Ophthalmologic abnormalities in institutionalized Congolese children with cognitive impairment.
Article in BMC ophthalmology, 2025. 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
objectivesTo determine the frequency and types of ophthalmologic anomalies in children with cognitive impairment, identify the causes of visual impairment in these children, and assess the relationship between the severity of cognitive impairment and ophthalmologic anomalies.
methodsA cross-sectional study was carried out between October 2023 and June 2024 on 80 children 7 to 17 years old with cognitive impairment and institutionalized in two centers in Kinshasa. Participants underwent a complete ophthalmologic examination and cognitive assessment using the Montreal Cognitive Assessment (MoCA) test.
resultsThe median (interquartile range) age of the children was 14 (11-16) years. 55% were boys. Cognitive impairment was mild in 41.2%, moderate in 33.8%, and severe in 25% of the children. Overall, 74 (92.5%) children had at least one ophthalmologic abnormality, and 43.8% had multiple ophthalmologic abnormalities. Refractive errors (82.5%), stereoscopic disorders (22.5%) and strabismus (12.6%) were the most frequent disorders. Twenty-seven (33.7%) children had vision impairment. The causes of vision impairment were refractive errors (46.7%), strabismus amblyopia (20%), and cataract (13.3%). There was a significant association between the severity of cognitive impairment and both visual impairment and defective stereopsis (p = 0.035).
conclusionsOphthalmologic manifestations are frequent in children with cognitive deficits. They are dominated by ametropia. A substantial proportion of these children are visually impaired. Periodic ophthalmologic screening of these children via conventional pediatric health system or school health services is recommended.
