Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie 2024年7月12日PURPOSE: To investigate the real-world 2-year treatment outcomes of intravitreal brolucizumab (IVBr) for neovascular age-related macular degeneration (nAMD). METHODS: This multicenter, prospective, and interventional study included 53 eyes treated with brolucizumab from October 2020 to August 2021 at 3 institutions. A modified treat-and-extend (TAE) regimen with predefined discontinuation criteria was used. The mTAE regimen was discontinued if patients responded positively and achieved a treatment interval of 16 weeks twice with no sign of recurrence. The number of patients discontinuing TAE and the visual and anatomic changes at 1 and 2 years after the first IVBr were evaluated. RESULTS: Thirty-eight eyes from 38 patients (71%) completed the 2-year observation period and 7 eyes from 7 patients experienced intraocular inflammation (IOI). Of these 38 patients, 18 (47%) could discontinue the TAE at a median [interquartile range] of 13.1 [12.9-16.8] months after the first IVBr. Best-corrected visual acuity, central subfield retinal thickness, and central choroidal thickness were significantly improved compared with baseline at both 1 and 2 years after the first IVBr (all P < 0.001). An extension study revealed a 1-year recurrence rate of 5.6% (standard deviation, 5.4%) after TAE discontinuation. CONCLUSIONS: While IOI is a concern with brolucizumab, careful observation allows discontinuing the TAE regimen in patients treated with IVBr. Moreover, brolucizumab may reduce the risk of recurrence after treatment interruption. TRIAL REGISTRATION NUMBER: UMIN Clinical Trials Registry ( http://www.umin.ac.jp/ ; R000050688 UMIN 000044374).

Scientific reports 14(1) 9087-9087 2024年4月20日This single-center retrospective cohort study analyzed the 1-year real-world treatment outcomes of 63 consecutive eyes (of 60 patients) with neovascular age-related macular degeneration (nAMD) that were switched from intravitreal brolucizumab (IVBr) to intravitreal faricimab (IVF) and managed on a treat-and-extend regimen with discontinuation criteria. After the switch, patients opted to continue IVF, to switch back to IVBr, or receive photodynamic therapy (PDT). Thirty-eight patients continued IVF, 16 patients were switched back to IVBr, 2 patients received PDT, and 4 patients paused treatment. Best-corrected visual acuity (BCVA), central subfield thickness (CST), subfoveal choroidal thickness (sf-CT), and injection intervals were compared immediately before and 1 year after the initial IVF. Whereas there was no change in BCVA and CST; 0 [- 0.0969 to 0.125, P = 0.58], - 1.5 [- 27.8 to 13.5, P = 0.11] µm, respectively, sf-CT decreased significantly; - 19.5 [- 45.5 to 7.75, P = 0.015] µm. The patients switched back showed no significant change in sf-CT. The injection interval extended significantly in the IVF continuation and the switch-back group (2.0 and 3.0 weeks, respectively; [P = 0.0007 and 0.0078]) in eyes with a pre-switching interval of less than 12 weeks. Faricimab shows promise as a safe and effective alternative to brolucizumab for treating nAMD.

Journal of Medical Case Reports 18(1) 80-80 2024年2月29日BACKGROUND: This study reports the first cases of scleritis following intravitreal brolucizumab (IVBr) injection for nAMD, emphasizing the need to be aware of the possibility of scleritis following IVBr injections. CASE PRESENTATION: Case 1. A 74-year-old Japanese man with nAMD complained of conjunctivitis and decreased vision in the right eye 8 days after his eighth IVBr injection. Examination revealed scleritis without anterior inflammation. Topical 0.1% betamethasone and 0.3% gatifloxacin eye drops were started. The scleritis worsened in the following 2 weeks and became painful. He underwent sub-Tenon's capsule triamcinolone acetonide (STTA) injection. Two days later, he returned with a complaint of severe vision loss. Fundus examination revealed retinal artery occlusion, vasculitis, and vitreous opacity in the right eye. Vitreous surgery was performed. CASE 2: An 85-year-old Japanese woman with nAMD in the right eye complained of reddening of the eye 27 days after her fifth IVBr injection. Examination showed conjunctivitis and scleritis without anterior inflammation in the right eye. She was started on 0.1% fluorometholone and 0.5% levofloxacin hydrate eye drops. The scleritis worsened in the following 3 weeks. Her treatment was switched to 0.1% betamethasone eye drops. One month later, the scleritis had improved and a sixth IVBr injection was administered. There was no worsening of the scleritis at that time. However, 1 month after a seventh IVBr injection, she complained of severe hyperemia and decreased vision. Fundus examination revealed vitreous opacification. She underwent STTA, and the vitreous opacity improved in 24 days. Case 3. A 57-year-old Japanese man with nAMD complained of pain and decreased vision in the right eye 21 days after a fourth IVBr injection. Examination revealed scleritis with high intraocular pressure but no anterior chamber or fundus inflammation. STTA and topical eye drops were performed. One month later, scleritis improved but visual acuity didn't due to progression of nAMD. CONCLUSIONS: Intraocular inflammation following IVBr injection may progress to the posterior segment. Scleritis can occur after IVBr injection, and topical eye drops alone may not be sufficient for initial treatment. Clinicians should consider the possibility of scleritis in patients with worsening inflammation after IVBr injection.
