Publication Clinical Profile of Low Vision in Children(Institute of Medicine, 2021) Gupta, Jewel D; Bhattarai, Sanjeev; Sharma, Anand K; Joshi, Niraj D; Gautam, Pragati; Chhetri, SurajABSTRACT Introduction: Visual impairment in children is more common in developing countries like Nepal. A low vision service has been found to be effective in significantly improving their overall development and quality of life. The main aim of this study was to determine the causes of low vision in pediatric population along with their refractive error distribution and visual functions. Methods: A descriptive cross sectional study was carried out in Tribhuvan University, BP Koirala Lions Center for Ophthalmic Studies. A total of 50 low vision children were under went detail low vision examination. They were selected through purposive sampling. Data was analyzed by using the descriptive and inferential statistics with SPSS version 19.0. Results: The study findings showed, most common cause of visual impairment in low vision children was refractive error (20%), followed by congenital cataract (18%) and macular dystrophy (16%). The most commonly prescribed low vision device for distance was telescope and for near was spectacle magnifier. There was average acuity improvement of five lines in distance visual acuity with low vision devices. Conclusion: The study concluded that refractive error and congenital cataract being the commonest cause of low vision in children, which reflect poor accessibility of care service among Nepalese children. Refractive error, the major cause of visual impairment could have been managed even in primary eye care center in Nepal. Children with impairment have potential visual acuity that can be improved with low vision services.

People are unaware of colour vision defect due to which they suffer in various aspects of their career. The purpose of this study was to explore the colour vision defect pattern among patients attending tertiary eye centre, Kathmandu, Nepal. Methods: A hospital based, retrospective study was conducted to evaluate the defective colour vision pattern in patients attending B.P. Koirala Lions Centre for Ophthalmic Studies, Institute of Medicine, Kathmandu, Nepal where total of 692 subjects medical case sheets were reviewed and included in the study from September 2018 to April 2019. Results: Among 692 patients enrolled in the study, 272 (39.30%) patients were found to have CVD . Among 272 CVD,227(83.45%) were males and 45(16.54%) were females. Congenital colour vision defect was found in 139 (26.73%) males and 21 (13.81%) females. Acquired color vision defect was found in 88 (16.92%) males and 24 (15.78%) females . When congenital CVD was observed, deutan (28.3%) CVD was more prevalent than protan (22.79%) and tritan defect (7.72%). For acquired CVD, non-specific type of CVD (8.92%) was more prevalent followed by tritan CVD (5.35%). Conclusion: Significant proportion of patient presenting for eye care at tertiary eye hospital have color vision defects. Congenital CVD was found more in males than females whereas acquired color vision defect was found almost in same proportion in both males and females.
