Efficacy of Intravitreal Brolucizumab Switch in Pachychoroid Neovasculopathy.
Article in Ophthalmology and therapy, 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
introductionThis study aimed to evaluate the anatomical and functional outcomes of switching to intravitreally administered brolucizumab (Beovu
methodsTwenty-three eyes of 21 patients with exudative PNV, who were switched to brolucizumab between April 2021 and December 2023, were retrospectively enrolled. All patients had previously received at least one injection of another anti-VEGF agent. Following the switch (baseline), patients received brolucizumab under a pro re nata regimen and were followed for 12 months. Best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CT), and height of IRF, SRF, SHRM, and pigment epithelial detachment (PED) were assessed at baseline and at the 12-month follow-up.
resultsAt 12 months after the switch to brolucizumab (mean 5.26 injections), BCVA remained stable (20/50, 0.4 logMAR). However, significant anatomical improvements were observed, including a reduction in SRF (97-18 µm, p = 0.002), SHRM (75-0 µm, p = 0.008), and CT (379-337 µm, p < 0.001). Resolution of IRF was achieved in 70% of eyes and SHRM in 87%. A median of 2 brolucizumab injections were required to achieve fluid control (absence of both IRF and SRF). Notably, the number of injections needed for complete SRF resolution predicted final BCVA.
conclusionIn our cohort of patients with PNV, switching to brolucizumab demonstrated a significant anatomical response, leading to a reduction in exudative features. While BCVA remained stable, the number of brolucizumab injections required to resolve SRF emerged as a predictor of final visual outcome, suggesting that an earlier switch in non-responders might optimize anatomical results. The safety profile of brolucizumab in this study was favourable, with no severe inflammatory adverse events reported.
