    Acute retinal necrosis (ARN) is a rare viral endophthalmitis, and human herpesvirus is the principal pathogen. Early diagnosis and treatment are critical to avoid visual impairment by ARN, and pars plana vitrectomy (PPV) is required in advanced cases. In this study, we evaluated the transition of viral load in ocular fluids of ARN eyes with varicella-zoster virus (VZV) after intravenous acyclovir treatment. Fourteen eyes of 13 patients were analyzed retrospectively. All patients received intravenous acyclovir treatment, and eventually, all eyes underwent PPV. A polymerase chain reaction (PCR) test showed a 100% detection rate in all aqueous humor samples collected before the treatment (Pre-AH), as well as aqueous humor (Post-AH) and vitreous fluid samples (VF), collected during PPV conducted after the treatment. Within eight days or less of acyclovir treatment, viral loads both in AH and VF did not decrease significantly. Furthermore, the viral load of Pre-AH had a strong correlation with that of VH. These data suggest that in ARN eyes with VZV infection, the AH sample for the PCR test was reliable to confirm the pathogen. We propose that short-term treatment of intravenous acyclovir may be insufficient for reducing intraocular viral load, and the Pre-AH sample could be a predictor of viral activity in the eyes after acyclovir treatment.

    Purpose: To investigate the clinical features and visual outcome of young Japanese patients with uveitis.Methods: Patients younger than 18 years who presented with uveitis at the University of Tokyo Hospital between 2000 and 2018 were retrospectively reviewed.Results: The study comprised 98 patients whose mean age was 12.3 ± 3.8 years. Anterior uveitis was present in 52.0%, panuveitis in 37.8%, and posterior uveitis in 10.2%. The most common diagnosis was juvenile chronic iridocyclitis (JCI) (29.6%) followed by tubulointerstitial nephritis and uveitis syndrome (4.1%) and neuroretinitis (4.1%). Thirty-nine patients received systemic anti-inflammatory treatment. Among all subjects, 56% presented with ocular complications and 20% underwent ocular surgery. Visual acuity of 20/200 or less was observed in 6.2%. The common causes of decreased vision were hypotony, serous retinal detachment, and pupil disorder.Conclusions: JCI was the most common diagnosis. Hypotony, serous retinal detachment, and pupil disorder can lead to visual loss.

    Purpose: To compare standard fluorescein angiography (FA) and ultra-wide-field (UWF) FA in evaluating sarcoid uveitis activity using the scoring system adopted by the Angiography Scoring for Uveitis Working Group (ASUWG).Methods: Standard and UWF FA images of 36 eyes with sarcoid uveitis were acquired on the same day. Three graders independently graded 72 FA images using the ASUWG scoring system. We evaluated inter-observer variability using the intra-class correlation coefficient (ICC) and compared scores of each angiographic sign.Results: The ICC was 0.77 for standard FA and 0.87 for UWF FA, with respective total scores of 12.0 and 14.6. UWF FA had higher scores than standard FA for optic disc hyperfluorescence, posterior retinal vascular staining and/or leakage, and peripheral capillary leakage.Conclusions: The scores for UWF FA had a higher ICC than those for standard FA in evaluating sarcoid uveitis. Peripheral capillary leakage scores were particularly high for UWF FA.

    PURPOSE: To clarify the prevalence of secondary glaucoma (SG) and its speed of progression in patients with herpes simplex virus (HSV)-anterior uveitis (AU), varicella zoster virus (VZV)-AU, and cytomegalovirus (CMV)-AU. METHODS: In total, 170 patients with herpetic AU were enrolled in this retrospective observational case series. Patients with visual field (VF) defects and glaucomatous disc abnormalities were diagnosed with SG. Moreover, the speed of SG progression was defined as decreasing mean deviation (MD) values per year. SG prevalence and annual MD-value decrease were compared among the three types of herpetic AU. RESULTS: SG prevalence was 16%, 9%, and 72% in patients with HSV-AU, VZV-AU, and CMV-AU, respectively. Patients with CMV-AU had the highest SG prevalence (odds ratio = 3.15; 95% confidence interval = 1.15-8.65; P < 0.05). Furthermore, the annual MD-value change was significantly higher in SG caused by CMV-AU than in that caused by HSV/VZV-AU (-2.6 ± 2.4 dB/year and -0.45 ± 0.54 dB/year, respectively; P < 0.05). CONCLUSIONS: Our results demonstrated that patients with CMV-AU may have a higher risk and faster speed of progression of SG than patients with HSV/VZV-AU. Therefore, clinicians should monitor glaucoma onset and VF-defect progression in patients with CMV-AU.

    PURPOSE: Retinal vasculitis and occlusive changes are important signs of posterior uveitis and are possible diagnostic markers for uveitis. However, the frequency of arteritis and phlebitis in various uveitis entities, including infectious uveitis (IU) and non-infectious uveitis (NIU), have not been systematically investigated. STUDY DESIGN: Retrospective. METHODS: We investigated the frequency of retinal vascular inflammatory and occlusive changes in patients with IU and NIU. The study included 283 patients with intermediate, posterior, or pan-uveitis who were diagnosed with IU (presumed tuberculous uveitis, acute retinal necrosis, cytomegalovirus retinitis, human T-cell lymphotropic virus type 1-associated uveitis, toxoplasmic retinitis, syphilitic uveitis, rubella virus-associated uveitis, fungal endophthalmitis, and bacterial endophthalmitis) or NIU (sarcoidosis, Behçet's disease, Vogt-Koyanagi-Harada disease, human leukocyte antigen-B27-associated uveitis, systemic lupus erythematosus retinopathy, psoriatic uveitis, rheumatoid arthritis/collagen disease-associated uveitis, multiple sclerosis-associated uveitis, and sympathetic ophthalmia). All patients underwent fluorescein angiography (FA) and color photography examinations of the fundus. Presence of inflammatory and occlusive changes was determined by FA images. RESULTS: Significantly higher positive ratios of phlebitis, vein sheathing, vein occlusion, arteritis, artery sheathing, artery occlusion, and avascular areas were observed in the IU group than in the NIU group (p < 0.05). Notably, the discrepancy between IU and NIU was prominent with regard to retinal arterial changes (arteritis [57.9% vs 11.2%], inflammatory artery sheathing [33.7% vs 0%], and artery occlusion [22.1% vs 3.7%], respectively; p < 0.0001). CONCLUSION: Findings of vasculitis and occlusion, especially in retinal arteries, in FA strongly suggest an infectious origin of active uveitis.

    Treatment of uveitis is complicated because of its multiple aetiologies and elevation of various inflammatory mediators. To determine the mediators that are elevated in the vitreous humor according to the aetiology of the uveitis, we examined the concentrations of 21 inflammatory cytokines, 7 chemokines, and 5 colony-stimulating/growth factors in vitreous samples from 57 eyes with uveitis associated with intraocular lymphoma (IOL, n = 13), sarcoidosis (n = 15), acute retinal necrosis (ARN, n = 13), or bacterial endophthalmitis (BE, n = 16). Samples from eyes with idiopathic epiretinal membrane (n = 15), which is not associated with uveitis, were examined as controls. Heat map analysis demonstrated that the patterns of inflammatory mediators in the vitreous humor in eyes with uveitis were disease-specific. Pairwise comparisons between the 5 diseases showed specific elevation of interferon-α2 in ARN and interleukin (IL)-6, IL-17A, and granulocyte-colony stimulating factor in BE. Pairwise comparisons between IOL, ARN, and BE revealed that levels of IL-10 in IOL, RANTES (regulated on activation, normal T cell expressed and secreted) in ARN, and IL-22 in BE were significantly higher than those in the other 2 types of uveitis. These mediators are likely to be involved in the immunopathology of specific types of uveitis and may be useful biomarkers.

    AIMS: To investigate susceptible human leukocyte antigen (HLA) alleles and their associations with clinical features in Thai patients with Behçet's disease (BD). METHOD: Eighteen HLA-A and 36 HLA-B alleles were determined in 42 Thai BD patients and 99 healthy controls (HCs) by reverse line blot assay, and reconfirmed by MICRO SSP assay. RESULTS: The BD patients had significantly higher allele frequency (AF) of HLA-B*51 than the HCs (13.10% vs 5.05%, P = .025). The AF of HLA-A*26, -A*26:01 and -B*51:01 also was higher and almost reached statistical significance (5.59% vs 1.52%, P = .054, 5.95% vs 1.52%, P = .054 and 10.71% vs 4.04%, P = .051, respectively). However, the BD patients had significantly higher AF of either HLA-A*26:01 or -B*51:01 (16.67% vs 5.56%, P = .005), or -A*26:01 or -B*51X (19.05% vs 6.56%, P = .003). The AF of HLA-B*51:01 and -B*51X increased significantly in -A*26:01 non-carrier BD patients (12.16% vs 4.17%, P = .024 and 14.86% vs 5.21%, P = .019, respectively); and that of HLA-A*26:01 was significantly higher in -B*51X non-carrier BD patients (7.58% vs 1.67%, P = .034). HLA-B*51:01 associated significantly with the presence of posterior uveitis and visual impairment (18.18% vs 2.50%, P = .031 for both conditions). HLA-B*51:01 was not observed in BD patients with gastrointestinal involvement or arthritis. Furthermore, the AF of HLA-B*51:01 was significantly higher in HLA-A*26:01 non-carrier BD patients without arthritis (17.30% vs 0%, P = .050). CONCLUSION: HLA-B*51:01 was a susceptible allele for Thai BD patients, and associated with posterior uveitis and visual impairment. HLA-A*26:01 was another susceptible allele in HLA-B*51X non-carrier patients. The protective effect of HLA-B*51:01 on arthritis needs further investigation.

    Purpose: We investigated clinical characteristics of ocular Behçet's disease (BD) patients treated in the 1990s and the 2000s.Methods: We retrospectively examined records of 68 newly arrived patients with ocular BD followed for more than 4 months during the 2000s and compared to those of 107 patients during the 1990s. Patient profiles, ocular and systemic symptoms, frequency of ocular attacks, BD ocular attack score 24-6 months (BOS24-6M), best-corrected visual acuity (BCVA), and immunomodulatory treatment were noted.Results: Clinical characteristics in the 2000s showed increases in iridocyclitis type, intestinal-, vasculo-, and neuro-BD cases, oral corticosteroid, methotrexate, and infliximab therapy usage, cataract and glaucoma surgery, and pseudophakia, and decreases in BOS24-6M and cyclophosphamide usage. BCVA of 20/30 or better at the final visit was slightly increased in the 2000s.Conclusions: Milder ocular BD tendency was seen in cases in the 2000s, whereas the incidence of special type of BD might be increasing.

    Recently developed technologies have revealed that the genomes of many organisms produce transcripts that do not encode proteins. These are called non-coding RNAs. Long non-coding RNAs (lncRNAs) are important regulators of the expression of their target genes at the levels of transcription, translation, and degradation. Multiple studies have demonstrated a role for lncRNAs in various biological responses, including pathogenic infection. Upon pathogenic infection, the expression levels of lncRNAs are dynamically altered, suggesting that lncRNAs are involved in the host immune response or propagation of pathogens. In this review, we focused on host lncRNAs that are involved in pathogenic infection. Some host lncRNAs act as host defense molecules to prevent pathogenic proliferation, while others are utilized by the pathogen to enhance the propagation of pathogens.

    PURPOSE: To investigate the clinical features of patients with ocular inflammation associated with relapsing polychondritis in Japan. METHODS: Ocular findings, systemic symptoms, and therapies were analysed retrospectively. RESULTS: Nine of 11 patients had scleritis (diffuse scleritis: six patients, posterior scleritis: two patients, episcleritis: one patient) and two patients had anterior uveitis. All cases were bilateral, and ten patients experienced recurrent episodes. Auricular chondritis was the most common systemic symptom. Ten patients were administered systemic steroids, and five patients were administered other immunosuppressive medications for severe systemic symptoms. At their last visit, none of the patients had decreased visual acuity that resulted from relapsing polychondritis-associated ocular inflammation. CONCLUSIONS: Ocular inflammation is often bilateral and recurring. Patients with ocular inflammation must be questioned regarding systemic symptoms so that the signs of relapsing polychondritis are not overlooked. Early diagnosis and prompt, appropriate treatment are important because relapsing polychondritis is a potentially lethal disease.

    AIMS: International criteria for the diagnosis of ocular sarcoidosis (OS) was established by the first International Workshop on Ocular Sarcoidosis (IWOS) and validations studies revealed certain limitations of the criteria. To overcome the limitations, revised IWOS criteria was established in an international meeting. This manuscript was aimed at reporting the revised IWOS criteria. METHODS: A consensus workshop was carried out to discuss and revise the IWOS criteria. The workshop was held on 27 April 2017, in Nusa Dua, Bali, Indonesia. Prior to the workshop, a questionnaire proposing revised criteria and consisting of one item for differential diagnosis, seven items for ocular clinical signs, 10 items for systemic investigations and three categories of diagnostic criteria was circulated to 30 uveitis specialists. Questionnaire items with over 75% support were taken as consensus agreement; items with below 50% support were taken as consensus disagreement and items with 50%-75% support were discussed at the workshop. Of the latter items, those supported by two-thirds majority in the workshop were taken as consensus agreement. RESULTS: The survey and subsequent workshop reached consensus agreements of the revised criteria for the diagnosis of OS as follows: (1) other causes of granulomatous uveitis must be ruled out; (2) seven intraocular clinical signs suggestive of OS; (3) eight results of systemic investigations in suspected OS and (4) three categories of diagnostic criteria depending on biopsy results and combination of intraocular signs and results of systemic investigations. CONCLUSIONS: Revised IWOS criteria were proposed by a consensus workshop.

    Purpose: To clarify the relationship between fluorescein angiography (FA) leakage after infliximab therapy and ocular attack relapse in patients with ocular Behçet's disease (BD). Methods: Patients with ocular BD were divided into two groups based on the presence (Group 1) or absence (Group 2) of ocular attacks after IFX therapy. FA leakage was evaluated by FA score in each of the optic discs, macula, large retinal vessels, and capillary vessels. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the relationship between FA score after IFX therapy and ocular attack relapse. Results: The areas under the curves obtained from the ROC curve of optic disc score and capillary vessels score after IFX therapy were 0.867 (95% confidence interval [CI]: 0.788-0.946) and 0.788 (95% CI: 0.649-0.927), respectively. Conclusions: FA leakage in the optic disc and capillary vessels after IFX therapy was strongly related to ocular attack relapse.

    This study aimed to clarify the association between the retinal leakage site on fluorescein angiography (FA) and subfoveal choroidal thickness (SCT) measured using enhanced depth imaging optical coherence tomography (EDI-OCT). Twenty-two patients with Behçet's uveitis were retrospectively selected in this study. They underwent EDI-OCT and FA in both the active and convalescent phases. The associations of the changes between the active and convalescent phases in SCT and in FA leakage in various retinal areas (total retina, peripheral retina, macula, and optic disc) were examined. The changing rates of SCT between the two investigated phases were significantly associated with the changes in total FA leakage scores (y = 1.79X+ 11.7, r2 = 0.210, p < 0.05). Furthermore, the changes in FA leakage scores in the macula were correlated with the changing rates in SCT (y = 3.72X+ 13.9, r2 = 0.219, p < 0.05). By contrast, there were no significant associations between the changes in SCT and those in leakage from the peripheral retina or the optic disc on FA. These findings demonstrate that SCT may reflect macular vasculitis as determined using FA, and SCT measurement could be a non-invasive method to investigate inflammation near the macula in Behçet's uveitis.

    Background: Adalimumab, a human anti-tumor necrosis factor-ɑ monoclonal antibody, was recently reported to be effective in lowering the risk of recurrence of noninfectious uveitis. This is the first case series of adalimumab administrations for relentless placoid chorioretinitis (RPC) patients. Case Presentation: We report 2 cases of RPC where successful treatments were achieved with adalimumab. A 34-year-old woman developed conjunctival hyperemia, mild iridocyclitis, and multiple atrophic retinal lesions, along with exudative changes that were widespread from the posterior pole to peripheral retina in both eyes. The diagnosis of RPC was made based on the characteristic recurrences of choroiditis despite systemic corticosteroid and cyclosporine. Adalimumab therapy was introduced to the patient, and thereafter no recurrence was observed while tapering the immunosuppressive agents. The second case was a 22-year-old man with visual deterioration in both eyes who exhibited widespread multiple chorioretinal atrophic lesions. We diagnosed the case as RPC based on characteristic clinical findings and recurring chorioretinitis during tapering of systemic corticosteroids. Adalimumab therapy was administrated, and immunosuppressant dosage was successfully reduced without any recurrences. Conclusions: In the current two RPC cases, adalimumab was quite effective and useful to reduce the dosages of systemic immunosuppressants. Further study is necessary to confirm the effectiveness of adalimumab in RPC patients.

    Noninfectious uveitis (NIU), which pathogenesis is often autoimmune nature, occurs as a symptom of systemic syndromes or only in the eye. The standard treatment of NIU is local, topical, and oral administration of corticosteroids (CS) in combination with immunomodulatory therapy (IMT). However, additional therapeutic strategies involving topical and systemic administration of CS or others to treat relapse or exacerbation of ocular inflammation in NIU which present as various ocular manifestations have not been established. The aim of this study was to investigate therapeutic strategies used for various ocular inflammations in relapse or exacerbation of NIU and to evaluate factors associated with the treatment pattern in Japan. The subjects were 198 eyes of 156 NIU patients with relapse or exacerbation of ocular inflammation at 6 university hospitals in Japan. The most frequent disease was sarcoidosis in 23.7% of the cases, followed by Behçet disease (BD) in 21.2%, Vogt-Koyanagi-Harada (VKH) disease in 13.6%, acute anterior uveitis (AAU) in 5.6%, tubulointerstitial nephritis and uveitis syndrome (TINU) in 4.0%, and juvenile idiopathic arthritis (JIA)-associated uveitis in 3.0%. Common ocular findings were worsened anterior inflammation (AI) in 67.2% of the cases, vitreous opacity (VO) in 46.5%, macular edema (ME) in 26.8%, retinal vasculitis (RV) in 23.7%, serous retinal detachment (SRD) in 9.1%, and optic perineuritis (OPN) in 4.0%. Reinforcement of betamethasone eye drop (ED) monotherapy for only AI in both unilateral and bilateral AI, sub-tenon injection of triamcinolone acetonide (STTA) for unilateral posterior inflammation including VO and ME, and systemic therapy using CS and/or IMT for bilateral anterior and posterior inflammation were significantly more frequent. Frequencies of exacerbated individual ocular findings in sarcoidosis and BD were similar, and severe ocular inflammation associated with panuveitis required both topical and systemic therapies. These results demonstrate that reinforcement of betamethasone EDs, topical administration of triamcinolone acetonide, and long-term administration of systemic corticosteroids are the major therapeutic strategies, and reinforcement of betamethasone EDs was used for exacerbated AI independently from its use for posterior inflammation. In addition, STTA was preferentially used for VO and ME associated with posterior inflammation.

    A 73-year-old female with a past medical history of breast cancer, who 10 years earlier experienced complete remission, complained of bilateral visual field disturbances and photopsia, 2 months prior. Tumour recurrence and metastatic lesions were not found during the medical examination, but antibodies against recoverin were detected in her serum. Despite immunosuppressive treatment with prednisolone and plasmapheresis, rapid and diffuse degeneration of the patient's photoreceptors and deterioration of her visual field were observed. This is a rare case of cancer-associated retinopathy with a long interval (10 years) between the diagnosis of the malignancy and visual loss.

    PURPOSE: Report global adalimumab safety and efficacy outcomes in patients with non-infectious uveitis. METHODS: Adults with non-infectious intermediate, posterior, or panuveitis were randomized 1:1 to receive placebo or adalimumab in the VISUAL I (active uveitis) or VISUAL II (inactive uveitis) trials. Integrated global and Japan substudy results are reported. The primary endpoint was time to treatment failure (TF). RESULTS: In the integrated studies, TF risk was significantly reduced (hazard ratio [95% CI]) with adalimumab versus placebo (VISUAL I: HR = 0.56 [0.40-0.76], p < 0.001; VISUAL II: HR = 0.52 [0.37-0.74], p < 0.001). In Japan substudies, no consistent trends were observed between groups (VISUAL I: HR = 1.20 [0.41-3.54]; VISUAL II: HR = 0.45 [0.20-1.03]). Adverse event rates were similar between treatment groups in both studies (854 to 1063 events/100 participant-years). CONCLUSIONS: Adalimumab lowered time to TF versus placebo in the integrated population; no consistent trends were observed in Japan substudies. Safety results were consistent between studies.

    Uveitis is a sight-threatening disease. Up to 35% of patients may have impaired vision. Inflammation of the uvea tissue has more than 60 etiologies. Previous reports have shown that 20-40% of uveitis cases were noninfectious. Some of them may be associated with systemic rheumatological and autoimmune diseases but some may affect the eyes only. The epidemiology and clinical situations of some specific uveitis entities vary worldwide because they are influenced by genetic, ethnic, environmental, and socioeconomic factors. The Asia-Pacific region comprises more than 30 countries. Epidemiology and patterns of uveitis vary greatly in this region. However, some uveitis entities, such as Behcet's disease, sarcoidosis, and Vogt-Koyanagi-Harada disease, are more common in this region. Many studies on the epidemiology, risk factors, and immune pathogenesis of this disease have been conducted. In this article, we review the epidemiology of noninfectious uveitis and special situations of these three uveitis entities in the Asia-Pacific region.

    Purpose: To report a case of acute retinal necrosis (ARN) caused by varicella-zoster virus (VZV) in an elderly patient with ocular sarcoidosis after oral corticosteroid indication. Methods: Retrospective case report. Results: A 75-year-old male with a past history of ocular sarcoidosis came with blurred left vision. Ocular findings in the left eye were consistent with ocular sarcoidosis, while no inflammation in the right eye. On day 14, intraocular inflammation in the left eye resolved by topical corticosteroid, but inflammatory cells were found in the right eye. Suspecting recurrence of ocular sarcoidosis, systemic corticosteroid was initiated. On day 21, inflammation worsened, and the presence of extended yellowish white peripheral retinal lesion in the right eye suggested ARN. Polymerase chain reaction (PCR) testing using ocular fluid detected 3.0 × 107 copies/ml of VZV DNA. Conclusions: In the case of poor response to immunosuppressive therapy in elderly uveitis, infection including ARN should be considered. Immediate PCR testing for pathogen screening is required.

    Several proteins have been proposed as candidate auto-antigens in the pathogenesis of Behçet's disease (BD). In this study, we aimed to confirm the cellular responses to candidate peptide autoantigens with high affinity for the HLA-B*51:01 molecule using computerized binding predictions and molecular dynamics simulations. We identified two new candidate peptides (HSP65PD, derived from heat shock protein-65, and B51PD, derived from HLA-B*51:01) with high-affinity to the HLA-B*51:01 binding pocket using the Immune Epitope Database for Major Histocompatibility Complex-I Binding Prediction and molecular dynamics simulations. The peptide-induced proliferation of lymphocytes from patients with BD, sarcoidosis, Vogt-Koyanagi-Harada disease (VKH) with panuveitis, systemic scleroderma (SSc) without uveitis, and healthy controls (HC) was investigated using the bromodeoxyuridine assay. The proliferative response of leukocytes to HSP65PD was significantly higher in BD (SI 1.92 ± 0.65) than that in sarcoidosis (SI 1.38 ± 0.46), VKH (SI 1.40 ± 0.33), SSc (SI 1.32 ± 0.31), and HC (SI 1.27 ± 0.28) (P = 0.0004, P = 0.0007, P < 0.0001, P < 0.0001, respectively, Mann-Whitney's U-test). The proliferative response of leukocytes to B51PD was also higher in BD than that in sarcoidosis, VKH, SSc without uveitis, and HC, whereas no significant differences were observed among the five groups in response to a control peptide derived from topoisomerase 1. A significantly higher response to HPS65PD and B51PD was observed in the HLA-B*51:01-positive patients with BD than in the HLA-B*51:01-negative patients. In conclusion, two peptides that had high affinity to HLA-B*51:01 in computerized binding prediction showed significantly higher response in HLA-B*51:01-positive patients with BD, indicating the usefulness of computerized simulations for identifying autoreactive peptides to HLAs.

    BACKGROUND: The distribution of uveitis varies with genetic, ethnic, geographic, environmental, and lifestyle factors. Epidemiological information about the patterns of uveitis is useful when an ophthalmologist considers the diagnosis of uveitis. Therefore, it is important to identify the causes of uveitis over the years in different regions. The purposes of this study were to characterize the uveitis patients who first arrived at the University of Tokyo Hospital in 2013-2015, and to analyze the changes in the patterns of uveitis from 2004 to 2012 to 2013-2015. METHODS: We retrospectively identified 750 newly arrived patients with uveitis who visited the Uveitis Clinic in the University of Tokyo Hospital between January 2013 and December 2015, using clinical records. We extracted data on patient age, sex, diagnosis, anatomic location of inflammation, laboratory test results of blood and urine, and chest X-ray and fluorescein fundus angiography findings for each patient. In addition, we compared these data with those from 2004 to 2012 to analyze the changes in the patterns of uveitis. RESULTS: A definite diagnosis was established in 445 patients (59.3%). The most common diagnoses were herpetic iridocyclitis (7.5%), sarcoidosis (6.1%), Behçet's disease (4.4%), Vogt-Koyanagi-Harada disease (4.1%), and intraocular lymphoma (4.1%). The most frequent unclassified type of uveitis was suspected sarcoidosis (22.3%). Analysis of the changes in the patterns of uveitis in the central Tokyo area from 2004 to 2012 to 2013-2015 revealed notable increasing trends of herpetic iridocyclitis and intraocular lymphoma, and increasing trends of bacterial endophthalmitis, fungal endophthalmitis, and juvenile chronic iridocyclitis. In contrast, the frequency of sarcoidosis, Behçet's disease, and Vogt-Koyanagi-Harada disease decreased. CONCLUSIONS: The patterns of uveitis changed considerably from 2004 to 2012 to 2013-2015. Continuous investigations about the epidemiology of uveitis are needed to diagnose uveitis more accurately.

    RATIONALE: Chronic uveitis with immunosuppressive agents could develop chronic herpetic retinitis with varicella-zoster virus (VZV) or herpes simplex virus (HSV). Ocular Epstein-Barr virus (EBV) infection develops uveitis and vitritis, but the clinical feature of EBV retinitis is not typical as a viral retinitis. EBV retinitis is rare, and only a few cases of EBV retinitis have been reported. Herein, we describe a case of retinitis with EBV and VZV which were the primary viruses verified by multiplex polymerase chain reaction (PCR). PATIENT CONCERNS: A 75-year-old woman suffered from sudden visual loss in the left eye. She had been diagnosed with rheumatoid arthritis. At presentation, visual acuity (VA) was 20/400 in the left eye. Slit lamp examination disclosed fine white keratic precipitates with infiltrating cells and dense vitreous opacities in the anterior segment and vitreous. Fundus photographs showed multifocal chorioretinal scars in macula and peripheral retina, and granular lesions surrounding arcade vessels. DIAGNOSES: Ocular toxoplasmosis was primarily suspected. INTERVENTIONS: However, serological test showed negative of toxoplasmosis. Therefore, a diagnostic and therapeutic vitrectomy was performed. Vitreous fluid sample was used for multiplex PCR for detection of human herpesvirus (HHV) -1 to -8, toxoplasmosis and toxocariasis. OUTCOMES: Multiplex PCR detected 5.8 × 10 copies/mL of EBV-deoxyribonucleic acid (DNA), and 3.6 × 10 copies/mL of VZV-DNA in the sample. Therefore, we could diagnose the unidentified panuveitis a retinitis associated with double infection of EBV and VZV. At 85 days after the vitrectomy, VA of the left eye recovered to be 20/16. LESSONS: Elderly patients under immunosuppression may be susceptible to develop retinitis associated with infection of multiple HHVs, and multiplex PCR is an excellent tool to diagnose an unidentified panuveitis resembling this case.

    Candida lusitaniae is an uncommon cause of candidiasis in humans. Ocular manifestations of C. lusitaniae infection have not been reported. C. lusitaniae is either intrinsically resistant to amphotericin B or can acquire such resistance. We describe a case of bilateral endophthalmitis due to C. lusitaniae bloodstream infection in a liver transplant patient with rectal cancer. The patient suffered fungemia and endophthalmitis and was treated with liposomal amphotericin B. The isolate was identified as C. lusitaniae by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, the system based on biochemical tests, and sequencing of the internal transcribed spacer region. The minimal inhibitory concentrations were 0.06 μg/mL for amphotericin B and 2.0 μg/mL for fluconazole. Repeat blood cultures were negative and the endophthalmitis improved following treatment with liposomal amphotericin B. However, the treatment was changed to fluconazole due to nephrotoxicity. No recurrence occurred after completion of treatment.

    A 31-year-old woman developed bilateral painful red eyes. A slit-lamp examination revealed anterior diffuse scleritis. She had been diagnosed with palmoplantar pustulosis 2 years before. Further evaluation revealed hyperostosis of the sacroiliac joint and inflammation of the bilateral sternoclavicular joints and right sternocostal joint. Ultimately, she was diagnosed with SAPHO syndrome by rheumatologists after excluding other causative diseases. Scleritis associated with SAPHO syndrome is relatively uncommon. An identification of any systemic symptoms and early consultation with rheumatologists are key to making an early and correct diagnosis.

    PURPOSE: We report three cases of ocular inflammation and polymyalgia rheumatica without concomitant giant-cell arteritis. METHODS: Report of three cases. RESULTS: Polymyalgia rheumatica onset was at a mean age of 66.7 years, and ocular inflammation, which developed 7-21 months later, was bilateral in all patients. Ocular inflammation presented as episcleritis, scleritis, or anterior uveitis, and it emerged during the tapering of low-dose prednisolone prescribed for polymyalgia rheumatica in all patients. Recurrence of ocular inflammation was observed in two patients. CONCLUSIONS: Ocular inflammation associated with polymyalgia rheumatica was often bilateral and occurred during steroid tapering. Although this presentation is relatively uncommon, polymyalgia rheumatica should be considered in the differential diagnosis of older patients presenting with ocular inflammation, especially those with proximal myalgia and elevated inflammatory markers.

    Primary intraocular lymphoma (IOL) has a propensity for central nervous system (CNS) relapse within 2 years of initial diagnosis, affecting clinical outcome. To reduce CNS relapse, we performed the combination treatment protocols of intravitreal methotrexate injections, methotrexate-based systemic induction chemotherapy and consolidation high-dose cytarabine and reduced-dose whole brain radiation therapy (rdWBRT, 23·4 Gy) for B-cell primary IOL with or without newly diagnosed CNS involvement. All patients underwent longitudinal brain magnetic resonance imaging (MRI) and cognitive assessment for evaluation of treatment-induced leucoencephalopathy. Seventeen patients initiated and 16 completed the protocol treatment. CNS relapse occurred in 2 patients and intraocular relapse in 3. Four-year progression-free survival (PFS) was 74·9% and 4-year overall survival (OS) was 86·3%, with a median follow-up period of 48·9 months. Of 11 patients without CNS involvement, 1 had CNS relapse and 3 intraocular relapse, and 4-year PFS and OS was 72·7% and 88·9%, respectively. Although white matter abnormalities shown by MRI were significantly increased at 4 years after rdWBRT, only one patient developed mild cognitive impairment. The combination of intravitreal chemotherapy, prophylactic systemic chemotherapy and rdWBRT for primary IOL showed a potential to reduce CNS relapse rate and improved 4-year PFS and OS without increase of cognitive dysfunction.

    A 68-year-old male presented with blurred vision in both eyes. Ophthalmoscopy revealed bilateral prominent disc swelling and vitritis. No systematic neurological symptoms were observed. Magnetic resonance imaging revealed bilateral meningeal enhancement of the optic nerve. Small cell carcinoma was found, and antibodies against collapsing response-mediating protein-5 (CRMP-5) were detected in the serum. Ophthalmological manifestations disappeared during a decrease in tumour size with treatment for the malignancy. This case report describes this rare case of anti-CRMP-5 antibody-positive paraneoplastic perioptic neuritis without neurological symptoms, showing that prompt diagnosis and timely treatment of the underlying tumour are crucial to prevent increased levels of autoantibodies and irreversible damage to the nervous system.

    BACKGROUND: In 2014, Pang et al. reported three cases with vitelliform submaculopathy as a preceding lesion of primary intraocular lymphoma (PIOL). Here, we report a case with an atypical presentation of PIOL who initially presented with vitelliform submaculopathy, vitreous haze and preripheral retinal focus. CASE PRESENTATION: A 73-year-old female initially visited another hospital with a chief complaint of acute reduced vision in the right eye. Funduscopic examination of the right eye showed a yellowish retinal lesion at the fovea with vitreous haze and retinal foci scattered in the peripheral region. Spectral-domain optic coherence tomography (SD-OCT) revealed a hyperreflective subretinal debris above the retinal pigment epithelium (RPE) at the fovea, suggesting vitelliform submaculopathy. Vitrectomy was performed to improve visualization of the retinal lesions and for examination of PIOL. Vitreous cytology was class III and cytokine analysis of vitreous fluid showed increased IL-10 and an IL-10/IL-6 ratio >1, suggesting PIOL. Thereafter, there was a sub-RPE infiltration of presumed lymphoma in the nasal retina, and PCR analysis of anterior chamber fluid indicated IgH gene rearrangement, leading to diagnosis of PIOL. Three months later, there was complete disappearance of the vitelliform submacular lesion, with resultant disruption and thinning of the outer retinal layers on SD-OCT images. CONCLUSIONS: Clinicians should be aware of atypical manifestations of PIOL such as vitelliform submaculopathy and peripheral retinal foci with vitreous haze. The patient's unusual funduscopic changes are findings that have not reported in patients with PIOL.
