To determine the prevalence of dry eye diseases in general clinical ophthalmic practice in a hospital-based population in West Bengal, Eastern India, a cross-sectional study was undertaken among 3023 subjects with the age of >30 years, attending general ophthalmic clinic in a tertiary eye hospital. Demographics, detailed history and 6-items McMonnies' dry eye questionnaire were asked. Tear film break-up time (TBUT), Schirmer-I test, Rose Bengal (RB) staining, slit lamp examination and Meibomian gland dysfunction (MGD) were studied. Dry eye diseases were significantly higher in women than in men ie, 51.9% versus 48.1% (p<0.01). Symptom-based dry eye (one or more symptoms present often or most of the time) was diagnosed in 1234 subjects (40.8%). With symptoms and at least one sign [TBUT <10 seconds, RB staining (van Bjisterveld score: 4 or more) and Schirmer-I test =5 mm in 5 minutes], the prevalence of dry eye was 786 (26%). Different grades of Meibomian gland dysfunction (MGD) were detected in 957 cases (31.7%). Primary Sjogren syndrome was found in 21.5%; and 10.9% patients of dry eye had some form of systemic collagen vascular disorders. Using computers was not a risk factor in this geographical area. No significant correlation was seen between significant symptoms and positive signs in the study population. The prevalence of dry eye disease is high in West Bengal, Eastern India in hospital-based population. The risk is higher with age, female gender, systemic collagen diseases and with oral antidepressant/anxiolytic medication. Meibomian gland dysfunction is found to be common among dry eye subjects.
