A Prospective study of the effect of bromfenac on tear production

Abstract

Context: The effect of bromfenac on tear production of 100 healthy participants aged 16–35 (mean age 23.65 ± 4.38 years) was studied using Schirmer's test. Aim: This study, therefore, is primarily geared toward finding out whether the observed positive effect of bromfenac on the management of dry eye is only as a result of its anti-inflammatory effect on the ocular surface. Settings and Design: The pretest, posttest method of experimental design was used and the posttest was at 30-min interval. The tear production was evaluated before and after the administration of 0.09% of bromfenac. Materials and Methods: Participants were first screened of any systemic or ocular problems. The tear production of the participants' right eye (OD) was measured before the topical administration of bromfenac. A drop of bromfenac was administered, and the tear production of the same OD was measured at 30, 60, and 90 min later and recorded. Statistical Analysis Used: Repeated measures analysis of covariance and t-test methods were used. Results: A decrease in mean tear production from the mean baseline value (19.76 ± 4.61 mm/5 min) was recorded after 30-min interval at 30 min, 60 min, and 90 min, respectively. The lowest mean tear produced was observed at 60 min, this effect was found to be statistically significant (P
