Purpose:
To describe predisposing factors, ophthalmic manifestations, and magnetic resonance imaging (MRI) findings in children with cerebral visual impairment.
Methods:
A retrospective cross-sectional analysis of patients younger than 16 years with neuroradiological and clinical evidence of retrogeniculate visual pathway pathology was performed. Detailed histories, ophthalmic examinations, and MRI findings were compiled and analyzed.
Results:
Of the 88 cases included in the study, the median age was 32 months (range: 1 to 180 months). Ante-natal history and preterm delivery was positive in 25.0% and 37.5% of patients, respectively. A simple myopic astigmatism was the most common refractive error. Accommodative anomalies were noted in 6 children.
Conclusions:
The demographic trends found in the study were similar to those of developed nations, but the frequency of the predisposing factors varied. A comprehensive knowledge of cerebral visual impairment in the developing world can aid an earlier diagnosis, appropriate management, and the development of better rehabilitation teams.

Purpose:The aim of this study was to compare noncycloplegic refraction performed in school camp with that performed in eye clinic in children aged 6–16 years.Methods:A prospective study of children with unaided vision <0.2 LogMAR who underwent noncycloplegic retinoscopy (NCR) and subjective refraction (SR) in camp and subsequently in eye clinic between February and March 2017 was performed. A masked optometrist performed refractions in both settings. The agreement between refraction values obtained at both settings was compared using the Bland–Altman analysis.Results:A total of 217 eyes were included in this study. Between the school camp and eye clinic, the mean absolute error ± standard deviation in spherical equivalent (SE) of NCR was 0.33 ± 0.4D and that of SR was 0.26 ± 0.5D. The limits of agreement for NCR were +0.91D to − 1.09D and for SR was +1.15D to -1.06D. The mean absolute error in SE was ≤0.5D in 92.62% eyes (95% confidence interval 88%–95%).Conclusion:A certain degree of variability exists between noncycloplegic refraction done in school camps and eye clinic. It was found to be accurate within 0.5D of SE in 92.62% eyes for refractive errors up to 4.5D of myopia, 3D of cylinder, and 1.5D of hyperopia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
