Ocular disorders among persons living with HIV/AIDS in Osun State, Nigeria: a cross-sectional study.
Article 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
backgroundHIV/AIDS affects all the structures of the eye and the orbit with grave implications on vision and quality of life. More than half of persons living with HIV/AIDS (PLWHA) are at risk of developing at least one HIV-related ocular disorder in a lifetime. This study aims to determine the prevalence, spectrum, and correlates of ocular disorder among PLWHA in Osun State, Nigeria.
methodsA multicentre cross-sectional study of a randomly selected sample of PLWHA in Osun State. Participants were interviewed using semi-structured questionnaires and underwent detailed ophthalmologic clinical examinations. The outcome variables were presence or absence of ocular disorders and visual impairment. Descriptive statistics, Chi square test and binary logistic regression were used to analyse data using SPSS version 20.
resultsA total of 505 PLWHA (80% female) aged 3.5–80 years (median, 40.0) were enrolled. They had lived with HIV/AIDS for a median period of 3.0 years (range: 0-12.8), and over 90% were on highly active anti-retroviral therapy. Their median CD4 + T lymphocyte count was 400 cells/ µl (range: 8-1977). Prevalence of any ocular disorder was 53.9% (95% C.I. =49.6%-58.2%), while the prevalence of HIV-related ocular disorders was 5.4% (95% C.I. =3.4%-7.4%). Common HIV-related ocular disorders were uveitis (1%), presumed toxoplasmosis (0.8%) and neuro-ophthalmic disorders (0.8%), and Cytomegalovirus (CMV) retinitis (0.4%). Prevalence of visual impairment in the sample was 4.4%, and refractive errors (50.0%) and cataract (13.6%) were the common causes. Participants with CD4 + count of at least 500 cells/µl (OR = 0.24; 95% C.I.=0.07–0.89; p = 0.03); those without visual impairment (OR = 0.25; 95% C.I.=0.08–0.80; p = 0.02) and those without eye complaints (OR = 0.35; 95% C.I.=0.15–0.83; p = 0.02) were less likely to have HIV-related ocular disorders.
conclusionsOcular disorders were common among PLWHA in Osun State although the prevalence of HIV- related ocular disorders was low. Moreover, there appeared to be emergence of previously rare and potentially blinding disorders such as CMV retinitis.
