Assessment of Symptomatic Dry Eye Disease among Postgraduate Medical Students of KIST Medical College and Teaching Hospital using an Ocular Surface Disease Index Questionnaire.

Background Symptomatic dry eye disease is a growing public health challenge especially among those who are visual display unit users and other long-time near activity workers. Increased screen time, prolonged use of face mask and shortage of sleep among resident doctors increases the risk of developing dry eye disease that can affect their learning and social abilities. Data is insufficient on the prevalence of dry eye disease among postgraduate medical students in Nepal. Objective To find out the prevalence of symptomatic dry eye disease using an ocular surface disease index questionnaire among postgraduate medical students of KIST Medical College and Teaching Hospital. Method A cross-sectional study was conducted among three batches postgraduate medical students until 2023 of KIST Medical College and Teaching Hospital, Imadol, Lalitpur. A single validated symptom-based questionnaire with 12 questions was used to assess symptomatic dry eye disease. Result Total of 110 post-graduate medical students with mean age of 30.4 years, 67 males and 43 females were enrolled. Among them, 68 (61.8%) had dry eye disease. Severe dry eye was the commonest followed by mild dry eye. There was statistically significant association between dry eye disease with the increased screen time and suboptimal durations of sleep. Conclusion About half of postgraduate students faced symptomatic dry eye disease. It is advisable for residents to have optimum sleep as possible, limit screen time and establish regular break time along their exposure.
