Abstract

Introduction. Visual impairment caused by myopia has been a major global health issue. The incidence of myopia has increased rapidly in the past two decades. Inflammatory factors are one of the factors causing myopia. Previous study shows there is a correlation between NLR and degree of myopia. Purpose. This study aims to determine the correlation between NLR and degree of myopia in medical students from Faculty of Medicine, University of Sumatera Utara. Material and Methods. This study was a cross sectional design with an observational analytical study. The measurements were refraction examination and NLR values. Statistical analysis used was Kruskal Wallis and Anova correlation with 5% significance. Results. This study consisted of 42 myopic subjects detailed as 20 male subjects (47.6%) and 22 female subjects (52.4%) with mean age 25.64±2.99 years old. Distribution of mild, moderate and high myopia was 38.1%, 42.9% and 8% respectively with mean spherical equivalent -3.57±2.11 D. Mean NLR values were 2.07±0.88. NLR values were not statistically significant with degree of myopia (p=0.082) Conclusions. There was no statistically significant correlation between NLR and degree of myopia in medical students from Faculty of Medicine, University of Sumatera Utara.
