Real-world functional and anatomical outcomes of intravitreal aflibercept 8 mg in treatment-naïve neovascular age-related macular degeneration: a phenotype-based analysis by pachychoroid and polypoidal lesion status.
Article in International journal of retina and vitreous, 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
backgroundTo evaluate the short-term functional and anatomical outcomes of intravitreal aflibercept 8 mg in treatment-naïve neovascular age-related macular degeneration (nAMD), and to explore whether the early treatment response varied according to pachychoroid and polypoidal lesion status.
methodsThis retrospective, multicenter observational study evaluated 45 treatment-naïve eyes of 45 patients with nAMD who received three monthly loading injections of aflibercept 8 mg. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), central choroidal thickness (CCT), and exudative findings (subretinal fluid [SRF], intraretinal fluid [IRF], and subretinal hyperreflective material [SHRM]) were assessed at baseline and at 1, 2, and 4 months. Pachychoroid and polypoidal lesion status was determined using multimodal imaging. Longitudinal changes were analyzed using linear mixed-effects models, with subgroup analyses by pachychoroid and polypoidal lesion status.
resultsAt 4 months, mean BCVA improved from 0.27 ± 0.33 to 0.20 ± 0.31 logMAR (P = 0.005), CRT decreased from 382.1 ± 189.7 to 231.3 ± 109.1 μm, and CCT from 263.0 ± 146.5 to 231.0 ± 127.2 μm (both P < 0.001). The dry macula rate (absence of both SRF and IRF) increased from 17.8% to 75.6% (P < 0.001). Functional and retinal anatomical responses were broadly consistent across phenotypes, with no significant time-by-phenotype interactions for BCVA or CRT. Pachychoroid eyes showed a greater CCT reduction (interaction P < 0.001), but this was no longer significant after adjusting for baseline CCT. As exploratory observations, the time-by-polypoidal-lesion interaction for BCVA was not significant (P = 0.052), and residual SHRM at 4 months was present in 0% of polypoidal-lesion eyes versus 22.2% of those without (P = 0.067).
conclusionsIntravitreal aflibercept 8 mg led to significant short-term improvements in BCVA, CRT, CCT, and exudative findings in treatment-naïve nAMD, with benefit observed irrespective of pachychoroid or polypoidal lesion status.
