Abstract

The purpose of this study is to compare the effect of topical diclofenac and topical dexamethasone on anterior chamber flare and postoperative pain following rhegmatogenous retinal detachment (RRD) surgery. This prospective study included 40 eyes of 40 patients treated for RRD. Twenty-eight patients underwent scleral buckling and 12 patients underwent 20-gauge pars plana vitrectomy (PPV). For each surgical procedure, patients were postoperatively randomly divided into two groups: the first group received topical dexamethasone phosphate 0.1 % four times daily for 28 days; the second group received topical diclofenac sodium 0.1 % three times daily for 28 days. The inflammatory reaction in the anterior chamber was measured with laser flare photometry preoperatively and 1, 7, 14, 28, and 90 days postoperatively. Pain level was evaluated with Scott’s visual analog scale at day 1, 7, 14, and 28 postoperatively. For patients treated with scleral buckling, there was no significant difference between the two groups regarding mean aqueous flare at day 1 (p = 0.096), day 7 (p = 0.435), day 14 (p = 0.510), day 28 (p = 0.583), and day 90 (p = 0.423). The group who received diclofenac had significantly lower pain score at days 7, 14, and 28 (p = 0.048, p = 0.017, and p = 0.028, respectively). For patients treated with PPV, there was no significant difference between the two groups regarding mean aqueous flare at day 1 (p = 0.400), day 7 (p = 0.728), day 14 (p = 0.843), day 28 (p = 0.939), and day 90 (p = 0.568). Patients who received diclofenac had significantly lower pain score at days 7, 14, and 28 (p = 0.032, p = 0.030, and p = 0.023, respectively). Topical diclofenac seems to be as potent as topical dexamethasone in managing postoperative inflammatory response induced by surgery for RRD with better analgesic effect. Both of them are consequences of blood-aqueous barrier and blood-retinal barrier breakdown.
