Prevalence and pattern of dry eye symptoms among “okada” riders in Southwest Nigeria using the ocular surface disease index: A cross sectional study

Abstract

Background: Dry eye is a common disorder of the tear film that results in epithelial damage and the disruption of normal homeostasis at the ocular surface. It is a common ocular condition that is often missed in clinical diagnosis. The objectives of this study were to determine the prevalence and pattern of dry eye symptoms using the Ocular Surface Disease Index (OSDI) among commercial motorcyclists and also identify factors that may be responsible for dry eye symptoms in this population. Methods: This was a descriptive, cross-sectional, population-based study. Using a multistage random sampling technique, 422 commercial motorcyclists were surveyed from 10 units of registered commercial motorcyclists. Interviewer-administered OSDI questionnaires (face to face) were used, and visual acuity (VA) measurement was done. Results: The prevalence of dry eye symptoms in this study was 83.42%. Using the OSDI, the pattern of dry eye symptoms in this study showed that 21.56% had mild dry eye, 54% had moderate dry eye, and 7.82% had severe dry eye. Riders aged >50 years (86.90%), P
