Corneal endothelial morphology in vitiligo: a cross-sectional study with subgroup analysis of periocular involvement.
Observational study 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
purposeTo evaluate corneal endothelial morphology and anterior segment parameters in patients with vitiligo and to investigate the potential impact of periocular involvement on endothelial characteristics.
methodsIn this cross-sectional observational study, 50 patients with vitiligo and 50 age- and sex-matched healthy controls were enrolled. Vitiligo patients were subdivided according to the presence or absence of periocular involvement. All participants underwent comprehensive ophthalmologic examination including autokeratorefractometry, Goldmann applanation tonometry, slit-lamp biomicroscopy, axial length measurement, and specular microscopy. Corneal endothelial parameters including endothelial cell density (CD), hexagonality (HEX), coefficient of variation (CV), and total cell count (N) were analyzed. Statistical comparisons were performed using appropriate parametric and non-parametric tests.
resultsAge and sex distribution were comparable between groups (p>0.05). No significant differences were observed between vitiligo and control groups in spherical equivalent, axial length, central corneal thickness, or endothelial parameters (CD, HEX, CV, N) (p>0.05 for all). Subgroup analysis revealed significantly higher endothelial cell density in the periocular vitiligo group compared with the non-periocular subgroup (p=0.008), while other endothelial indices remained similar.
conclusionCorneal endothelial morphology appears preserved in patients with vitiligo. The disease does not seem to confer clinically significant reduction in endothelial reserve or increased surgical risk related to endothelial compromise. Periocular involvement may represent a biologically distinct subset; however, no evidence of endothelial vulnerability was observed. Longitudinal studies incorporating multimodal imaging are warranted.
