Study Design: A cross-sectional study included 209 medical students at a medical school in Korea.
Methods: Dry eye symptoms were assessed using a 9-item questionnaire, and DED was defined as having 1 or more dry eye symptoms often or all the time. The ocular surface disease index (OSDI) and visual analog scale (VAS) questionnaires were also administered to quantify the dry eye symptoms. A survey including demographic data, potential risk factors of DED, personal habits and psychological stress was also performed.
Results: .Of the 209 students, 188 (93 male and 95 female) completed the survey. The average age was 28.0 ± 2.5 (mean ± SD; range, 23 - 37) years. Prevalence of DED was 27.1% (51 / 188). Participants with DED had significantly higher VAS and OSDI than those without DED (P<0.001 for both). Univariate analysis revealed that female sex (P=0.001), CL wear (P=0.034), prolonged computer use (P=0.001) and higher psychological stress score (P<0.001) had significant association with DED. Multivariate analysis also showed the significant association between DED and female sex (P=0.026), CL wear (P=0.042), prolonged computer use (P=0.004) and higher stress score (P=0.014).
Conclusions: DED was prevalent among young Korean medical students. Its risk increased among females, CL wearers, prolonged computer users, and students with increased psychological stress.
