Evaluation of topical 0.03% flurbiprofen drops in the treatment of herpetic stromal keratitis

Purpose: The management protocol for herpetic stromal keratitis (HSK) is still controversial. We have attempted to compare the relative efficacy of topical dexamethasone 0.01 % and flurbiprofen 0.03% in combination with topical acyclovir 3% in HSK.
Methods: In this institutional, prospective, randomized, controlled, double-blind study, 45 clinically diagnosed cases of HSK were randomly distributed into three coded treatment groups — topical placebo, dexamethasone 0.01 %, and flurbiprofen 0.03% each in tapering frequency and in combination with acyclovir 3% ointment five times per day for four weeks. Therapeutic response was assessed every third day for four weeks. Decoding of the treatment groups was done at the conclusion of the study and data analysed.
Results: Four-week success rate was 93.3% (14 of 15) in the dexamethasone-acyclovir treatment group, 66.7% (10 of 15) in the flurbiprofen-acyclovir treatment group and 20% (3 of 15) in the placeboacyclovir treatment group.
Conclusion: While dexamethasone in combination with acyclovir gives the best results in HSK with minimal side-effects, the role of topical flurbiprofen seems promising.
