RESUMO
PURPOSE: The aim of the present randomized, double-blind, placebo-controlled clinical trial was to assess the efficacy and tolerability of 0.5% indomethacin (INDOM) eye drops in adult patients suffering from macular edema (ME) related to different etiology uveitis. METHODS: Forty-six eyes of 31 adult patients (20 females and 11 males) mean age 39 years, affected by inflammatory ME, were randomized to receive a dose of commercial 0.5% INDOM eye-drops four times per day (16 subjects = 23 eyes) or placebo (the vehicle of INDOM, 15 subjects = 23 eyes) during a 6-month active therapy follow-up. Study assessment at each visit included visual acuity testing (VA), slit-lamp examination, IOP evaluation, and Heidelberg Spectralis optical coherence tomography (OCT) central foveal thickness (CFT) measurement. Any variation in subjective symptoms and tolerability was also detected. RESULTS: Statistical analysis showed, from baseline to the 6-month visit, a significant reduction in CFT (P < 0.0001) and a significant improvement in VA only in the 0.5% INDOM-treated group; a global reduction of discomfort symptoms was present in both groups (P < 0.001). CONCLUSIONS: The four times per day administration of 0.5% INDOM eye drops in eyes affected with uveitic ME from different etiologies, compared with placebo, is associated with a significant reduction in ME at the 6-month follow-up visit, as measured by spectral-domain optical coherence tomography (SD-OCT). However, not all eyes showed a complete resolution of ME because of vitreoretinal traction. (https://eudract.ema.europa.eu/index.html number, EUDRACT 2011-001522-20.).
