All the patients above 40 years of age, attending out patients department were screened by ophthalmologist using the Ocular Surface Disease Index (OSDI). Those patients who were diagnosed of dry eye by OSDI were further evaluated by Schirmer’s test and Tear film breakup time (TBUT). Result Out of 4470 patients attending Ophthalmology outpatient department 1599 patients were of age above 40 years. The overall prevalence of dry eye according to OSDI questionnaire was 25% (400). The mean age of patient with dry eye was 54 yrs. 169 were males (42.2%) and 231 were females (57.7%).
