Publication Ocular Survey in Kathmandu University Medical Students(Kathmandu University, 2022) Shrestha, P; Kaiti, R; Shyangbo, R; Dhakal, KABSTRACT Background Medical students spend long time in academic activities that increases the risk of developing refractive errors and dry eyes that can affect their learning and social abilities. Only a few studies are available regarding ocular problems and its contribution to visual impairment among medical students in Nepal. Objective To evaluate the ocular problems among the medical students in a University hospital. Method An observational, descriptive, cross-sectional study was conducted among five batches undergraduate medical students until 2022 of Kathmandu University School of Medical Sciences, Dhulikhel, Kavre. A self-administered questionnaire was used to obtain demographic data and information on visual problems followed by a detailed ocular examination that included refraction, color vision and Schirmer test. Result Total of 284 medical students (with 568 eyes) with mean age of 22.8 years, 179 males and 105 females were enrolled. Among them, 270 (47.5%) eyes were emmetropic. Simple Myopia was the commonest followed by Compound Myopic Astigmatism. The mean spherical equivalent in right and left eye were -0.914 ± 1.54 and -0.886 ± 1.53 respectively. Approximately 18% students had some form of dry eye. Nineteen students (6.7%) had color vision deficiency and 13 (4.6%) had deuteranomalia, 3(1.1%) had deuteranopia and 3(1.1%) had protanomalia. Conclusion Eye defects, like refractive errors, dry eyes and color blindness, are common among medical students. They need to be advised for frequent eye check up in order to diagnose eye defects timely and arrest visual impairment at early stage.

The large majority of vision impairment in school aged children is due to uncorrected refractive error. Hence, refractive errors are considered as a public health challenge. The aim of this study was to estimate the prevalence of refractive error and spectacle compliance among children in Tokha municipality, Kathmandu. Objective The aim of this study was to estimate the prevalence of refractive error and spectacle compliance among children from Tokha municipality, Kathmandu. Method A descriptive, cross-sectional study was conducted by enrolling 1366 children from Tokha municipality from 1st to 3rd week of April 2022 after obtaining the Institutional Review Board (Reference number:60/2079/80). Assent was taken from all children and informed consent was signed by the legal guardians of the children. All the samples underwent a comprehensive ocular history taking, visual acuity and refraction and ocular health assessments. The inclusion criteria was school going children within age group 5-16 years. Result Out of a total of 1366 samples, 10.91% (149) of the school children were identified to have refractive error. The primary type of refractive error observed was compound myopic astigmatism, which accounted for 52.3% (78) of the cases. A spectacle compliance rate of 72.15% was found. Conclusion Refractive error prevalence in this study is consistent with findings from other part of Nepal. The most common type of refractive error was compound myopic astigmatism. The frequency of refractive errors was notably higher among individuals who frequently use electronic devices, attend private schools, and reside in densely populated areas. It is recommended to organize regular community eye camps and conduct vision screenings to identify and promptly address refractive errors in children.
