Abstract
Purpose
Dry eye is a multifactorial disease of the ocular surface. It showed an increased incidence during the pandemic situation, which may be due to long hours of exposure to electronic gadgets. We aimed to find the prevalence of dry eye disease among medical students during the coronavirus disease 2019 (COVID-19) pandemic and pre-pandemic periods.
Methods
This was a cross-sectional study conducted in a tertiary care teaching institute. This was an institution-based, cross-sectional study conducted among medical students. A modified Ocular Surface Disease Index (OSDI) questionnaire was used to find the severity and prevalence of dry eye disease. Considering 95% confidence interval (CI) and prevalence as 50%, the calculated sample size was 271. Online responses were collected and entered in an Excel sheet. The Chi-square test, univariate and multivariate logistic regression were used for statistical analysis.
Results
Data were collected from 271 medical students; the prevalence of dry eye disease was 41.5 and 55.19 during the pre-pandemic and pandemic periods, respectively. There was a significant rise in dry eye disease cases during the pandemic when compared to pre-pandemic period (P < 0.05). The odds of getting dry eye disease were 1.7 times more during the pandemic than pre-pandemic.
Conclusion
The lockdown situation during the pandemic forced people to use electronic gadgets for work, recreation, and academics. Prolonged screen time predisposes to the development of dry eye disease.
