Background and objective: To evaluate the efficacy and safety of diclofenac 0.1% versus prednisolone acetate 1% following trabeculectomy with adjunctive mitomycin-C.
Patients and methods: The authors prospectively randomized chronic open-angle glaucoma patients who underwent trabeculectomy with adjunctive mitomycin-C to receive postoperatively either diclofenac 0.1% or prednisolone acetate 1% 4 times daily, to be tapered as inflammation resolved.
Results: In the diclofenac group (n = 14), the preoperative intraocular pressure of 30.4 +/- 13.1 decreased to 12.4 +/- 6.5 mm Hg at 6 months postoperatively. In the prednisolone acetate group (n = 12), the preoperative intraocular pressure decreased from 29.1 +/- 10.4 to 12.8 +/- 4.2 mm Hg at 6 months postoperatively (P = .85). The average number of medicines used 6 months postoperatively was 0.50 +/- 0.8 in the diclofenac group and 0.24 +/- 0.6 in the prednisolone acetate group (P = .36). Adverse events were similar between groups (P = .51). One patient in the diclofenac group underwent reoperation at 1 month due to uncontrolled intraocular pressure.
Conclusions: This study shows that following trabeculectomy with adjunctive mitomycin-C, a similar intraocular pressure result may be expected when either diclofenac or prednisolone acetate is prescribed postoperatively for intraocular inflammation.
