摘要

It is the inflammatory response of the conjunctiva to allergens such as pollen, animal dander, and other environmental allergens. The treatment consists of avoidance of the offending antigen, topical decongestants, antihistamines, mast cell stabilizers, non steroidal anti-inflammatory drugs and corticosteroids.

Methods: After taking institutional ethics committee approval, total n= 62 (33, 29) patients were enrolled. Patients were randomized and divided into two study groups (1-olopatadine, 2-epinastine). After prescribing the drug therapy (day 1), patients were asked to visit at 3,7,15 day and at 1month. At every visit, slit lamp examination was done. Changes in all sign/symptoms were recorded.

Results: Both the study drugs found to be equally efficacious except at few points. Only statistically marked difference was observed in papillary hyperaemia (p.
