Correlation of optic nerve on magnetic resonance imaging with visual acuity in children with cerebral visual impairment.
Article in Oman journal of ophthalmology. 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
aimThe aim of the study was to correlate the optic nerve dimensions at various locations on magnetic resonance imaging (MRI) with the visual acuity of children with cerebral visual impairment (CVI). MATERIALS AND
methodsA 1-year cross-sectional study was conducted in a tertiary care hospital involving 60 children aged 1 to 12 years diagnosed with CVI but without ocular pathologies. Visual acuity was evaluated using teller acuity cards (TACs). MRI of the brain and orbit was performed using three-dimensional high-resolution, volumetric heavily T2-weighted sequences to screen for brain pathologies and measure optic nerve dimensions at two locations. The correlation between visual acuity and optic nerve dimensions was analyzed. The Chi-square test was employed to assess significance using SPSS software.
resultsIn our study, 64% (
conclusionOur findings suggest that there may not be a direct correlation between optic nerve dimensions and visual acuity in children with CVI. However, optic disc changes do correlate with visual acuity, but optic disc changes alone are not a criterion for assessing visual function. Additionally, our study highlights the significance of a combined assessment by a neuro- ophthalmologist and neuro-pedaitrician in children with CVI.
