A comparative study of Olopatadine and Ketorolac eye drop with Ketorolac eye drop alone in seasonal allergic conjunctivitis

Ravindra Kumar Meena, M. L. Gupta, H.P. Sharma


Background: Seasonal allergic conjunctivitis is the most common allergic disorder seen in eyes. The aim of study was to compare the clinical efficacy of combination of 0.4% ketorolac and 0.1% olopatadine with 0.4% ketorolac alone in seasonal allergic conjunctivitis. Material and Method: The study was prospective, double blind parallel group comparative. Two hundred cases enrolled in the study. All the subjects were randomly divided in two groups, 100 in each. Group 1 patients received 0.4% ketorolac eye drop in both eyes 2 times a day and group 2 patients received combination of 0.1% olopatadine and 0.4% ketorolac in both eyes 2 times a day. Observations were collected at baseline and on day 3,7,15 and analyzed statistically regarding improvement in sign and symptoms. Result: In group 1, 50- 60% patients had no sign and symptoms on day 15 whereas in group 2 more than 95% patients showed improvement in clinical picture. p value was significant (p<0.0001) at day 15 in all sign and symptoms and on day 3 in itching and on day 7 in watering. Overall group 2 patients had better and earlier response regarding symptoms of itching at day 3. Conclusion: The combination of 0.1% olopatadine and 0.4% ketorolac was more effective than 0.4% ketorolac alone in seasonal allergic conjunctivitis patients.
