Non-infectious occlusive retinal vasculitis following switching from aflibercept 2 mg to aflibercept 8 mg in neovascular age-related macular degeneration: a case report.
Article in BMC ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAnti-vascular endothelial growth factor (anti-VEGF) therapy represents the standard of care for neovascular age-related macular degeneration (nAMD). Aflibercept 8 mg was recently introduced with extended dosing intervals and favorable safety outcomes in phase III trials. Although no confirmed cases of occlusive retinal vasculitis were reported in pivotal studies, rare inflammatory vascular events may emerge during broader real-world exposure. CASE PRESENTATION: A 74-year-old pseudophakic male with active nAMD in the left eye demonstrated significant anatomical and functional improvement following intravitreal aflibercept 2 mg. After switching to aflibercept 8 mg, the patient presented 26 days later with painful visual deterioration. Fundus examination revealed mild vitritis, segmental arterial sheathing, venous narrowing, and peripheral intraretinal hemorrhages. Fluorescein angiography demonstrated capillary non-perfusion and late vascular leakage. Optical coherence tomography confirmed cystoid macular edema. Extensive infectious and autoimmune investigations were negative. Systemic and local corticosteroid therapy resulted in regression of inflammation with partial visual recovery.
conclusionsNon-infectious occlusive retinal vasculitis may rarely occur following switching to aflibercept 8 mg. Early recognition and prompt anti-inflammatory treatment are critical to minimize irreversible ischemic damage. Continued post-marketing pharmacovigilance is warranted.
