Prevalence of Dry Eye Disease among University Students

Abstract

Purpose To determine the prevalence of dry eye disease (DED) and risk factors among young people based on the Ocular Surface Disease Index (OSDI) questionnaire. Methods The authors of the present study distributed the OSDI questionnaire to 263 university students. DED was diagnosed when the OSDI score was greater than 13 points. According to the OSDI score, DED was classified as mild (13-22 points), moderate (23-32 points), or severe (33-100 points). Additionally, the associations between the OSDI score and possible risk factors such as gender, contact lens use and allergic conjunctivitis were studied. Results Of 263 students, diagnosed DED was present in 133 (50.6%) and severe cases of DED were observed in 49 (18.6%). A high OSDI score was associated with female sex (p < 0.01), a history of allergic conjunctivitis (p = 0.02), contact lens use (p < 0.01), self-awareness of the dry eye symptoms (p < 0.01) and a history of clinically diagnosed DED (p < 0.01). Conclusions Prevalence of DED, which has been reported to be high in the elderly, was considered high at 50.6% among young people in the present study. Caution or education regarding DED is necessary for people who have a high OSDI score, particularly females, contact lens wearers and people with allergic conjunctivitis.
