Association between fusion visual function deficits and myopia in school-aged children: an analysis based on competitive binocular vision screening.

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
objectiveEven after refractive correction, myopic children remain at a significantly higher risk of visual function deficits compared to non-myopic children. Competitive binocular visual function testing is a screening method designed to simulate complex visual environments, specifically developed for the large-scale and rapid assessment of children’s visual performance under challenging conditions. This study aims to investigate whether visual function deficits observed in simulated complex environments are associated with myopia, thereby informing potential strategies for myopia prevention and control.
methodsA cross-sectional study was conducted involving 1,430 school-aged children from grades 1 to 6 at an elementary school in Wuxi in 2022. Competitive binocular visual functions (simultaneous perception, fusion, and stereopsis) were assessed and compared between myopic and non-myopic children.
resultsThe rate of fusion function deficits in the myopic group (35.80%, 256/715) was significantly higher than that in the non-myopic group (26.57%, 190/715). Myopic children had a 1.54 times higher risk of fusion deficits compared to non-myopic children (OR=1.54, 95% CI: 1.22–1.94). A weak positive correlation was observed between the degree of myopia and fusion deficits (r=0.087, P<0.01). Age stratification revealed that the fusion deficit rate in the lower-grade group (7–9 years old) (50.62%, 365/721) was significantly higher than that in the higher-grade group (10–12 years old) (11.42%, 81/709). Younger children had an 8.05 times higher risk of fusion deficits compared to older children (OR=8.05, 95% CI: 6.18–10.49). Gender differences showed that the fusion deficit rate in males (46.89%, 332/708) was significantly higher than that in females (15.79%, 114/722), with males having a 4.63 times higher risk than females (OR=4.63, 95% CI:3.64–5.89). No significant differences were observed in simultaneous perception or stereopsis between the myopic and non-myopic groups (P > 0.05).
conclusionMyopic children are more likely to exhibit deficits in competitive binocular fusion function. These findings indicate that early childhood may represent a potential critical period for intervention in fusion function development.
