Optical coherence tomography angiography imaging characteristics and clinical significance of the foveal vertical hyperreflective line in patients with macular neovascularisation.
Observational study in Eye (London, England), 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 investigate the incidence, characteristic manifestations, outcomes of changes, and potential clinical significance of the foveal vertical hyperreflective line (FVHL) on optical coherence tomography angiography (OCTA) in patients with macular neovascularisation (MNV).
methodsThis retrospective observational case series was conducted using OCTA images, fundus photographs, best-corrected visual acuity measurements, and other clinical information of the eyes of patients with MNV who were followed up for at least 3 months between January 2024 and October 2025. The incidence of FVHLs, OCTA characteristics, FVHL changes, and prognoses were analysed.
resultsAmong the 322 eyes of 161 patients with MNV, 14 patients (8.7%) showed FVHLs in 15 eyes. The mean age of the patients was 69.29 ± 12.68 years. Among the eyes with an FVHL, 13 were of patients with age-related macular degeneration-MNV and two were of patients with pathological myopia-MNV. All cases showing FVHLs occurred in the early stages of the disease course (within 1-3 months) and did not disappear during follow-up. Among the cases with FVHLs, 80% showed no obvious changes in the FVHLs and 20% showed weakened reflexes. The eyes that showed FVHL maintenance had a higher interdigitation zone/ellipsoid zone (IZ/EZ) repair rate (91.7%) than those with reflex-weakened FVHLs (p = 0.009).
conclusionsFVHLs were present in 8.7% of patients with MNV. The eyes that maintained FVHLs exhibited a higher degree of IZ/EZ restoration than the eyes with reflex-weakened FVHLs. This OCTA finding may provide a foundation for assessing the recovery responses of retinal photoreceptors and Müller cells.
