Abstract
Introduction: Dry eye is a disorder of the tear film due to tear deficiency or excessive tear evaporation, which causes damage to the interpalpebral ocular surface and is associated with symptoms of ocular discomfort. Dry eye syndrome is also known as keratoconjunctivitis sicca. It is far more prevalent than was previously considered. Reported prevalence ranges from 5.5% to 27.5% (age and sex adjusted).The present study was conducted in department of Ophthalmology, Government Medical College, Nagpur to estimate the prevalence of dry eye in a hospital based population, to assess subjective symptoms of dry eye patients, to evaluate risk factors attributable to dry eye and to evaluate role of investigative modalities in diagnosing dry eye .Eighty two patients above the age of 5 years participated in the study. After detailed history and investigations, the prevalence rate in our study was found to be 16 .4 percent. It was found that dry eye is common in older population, females, and in summer season. It is mostly seen in farmers, labourers, those exposed to ultraviolet rays, computer users and contact lens wearers .Dry eye is an under diagnosed disorder . Early screening and effective management can improve the quality of life of patients and decrease the morbidity due to ocular surface disorders.
