First-year real-world experience of intravitreal brolucizumab injection for refractory neovascular age-related macular degeneration.
Observational study in Japanese journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo investigate the first-year real-world anatomical and functional outcomes of intravitreal brolucizumab injection in eyes with refractory neovascular age-related macular degeneration (nAMD). STUDY
designRetrospective observational study.
methodsnAMD patients who showed poor response to previous anti-vascular endothelial growth factor (VEGF) agents were switched to brolucizumab. Functional and anatomical outcomes were evaluated at initial treatment of nAMD, after treatment with other anti-VEGF agents and after switching and treating with brolucizumab for 1 year. Safety profile was also evaluated after brolucizumab injection. Best-corrected visual acuity (BCVA), central foveal thickness (CFT), subfoveal choroidal thickness (SFCT), and the presence of fluid in different compartments (intraretinal fluid [IRF], subretinal fluid [SRF], pigment epithelial detachment [PED]) were assessed at each time point.
resultsA total of 40 eyes of 40 patients were included in the study. BCVA remained unchanged throughout treatment (p > 0.05). CFT did not change after treatment with other anti-VEGF agents (p = 0.588) but decreased after switching to brolucizumab (p < 0.001). SFCT decreased after treatment with other anti-VEGF agents (p = 0.025) but not after switching to brolucizumab (p = 0.236). Presence of SRF (p = 0.001) and PED (p = 0.001) decreased significantly after switching to brolucizumab, despite their persistence with prior treatments using other anti-VEGF agents. However, IRF persisted even after switching to brolucizumab (p = 0.745). Intraocular inflammation (IOI)-related adverse events were reported in 3 eyes (7.14%).
conclusionAnalysis of first-year real-world outcomes after switching to brolucizumab in nAMD patients refractory to other anti-VEGF agents showed improved anatomic outcomes, limited functional improvement and low incidence of IOI-related adverse events.
