PURPOSE: To compare the effect of topical indomethacin 0.1% solution with the effect of topical dexamethasone 0.1% phosphate solution on signs and symptoms of inflamed pterygium and pinguecula. METHODS: Of 50 consecutive patients who had inflamed pterygia (n = 17) or pingueculae (n = 33), met the study criteria, and signed an informed consent, one eye of each patient was evaluated in a comparative, prospective, randomized, double-masked, controlled study. Objective signs (conjunctival congestion, redness and edema, and staining of cornea) and subjective complaints (photophobia, pain, foreign-body sensation, discomfort, and tearing) were evaluated and scored. We also evaluated “total signs,” “total symptoms,” and “total score.” Group 1 (n = 25) received topical indomethacin 0.1% solution, and group 2 (n = 25) received a topical dexamethasone phosphate 0.1% solution six times daily for 3 days, then four times daily over the following 11 days. Patients were examined before treatment, on days 3, 7, and 14 after the treatment was initiated, and 2 and 4 weeks after the treatment was discontinued. RESULTS: In both groups, the scores for “total signs,” “total symptoms,” and “total score” were significantly lower (P = .001) by day 14. There were no differences between groups 1 and 2 for “total signs,” “total symptoms,” and “total score” at days 3, 7, and 14 (P = .07 to P = .88). After treatment was discontinued, the dexamethasone-treated group experienced a significantly greater recurrence of “total signs” (P = .023 at day 30, P = .02 at day 45), but there was no statistically significant difference in “total symptoms” and “total score.” Patients in group 2 reported more stinging after drops were administered than patients in group 1 (P = .002). CONCLUSIONS: This study indicates that topical indomethacin 0.1% solution is as effective as topical dexamethasone phosphate 0.1% solution for the treatment of inflamed pterygium and pinguecula and, therefore, is suggested as an effective treatment for these conditions.
