AIM:To investigate clinical efficacy of intravitreal ketorolac for the treatment of chronic cystoid macular edema after cataract surgery.

METHODS:A total of 38 patients with postoperative cystoid macular edema after cataract surgery coming to our hospital for treatment at 2014-2016 were collected. And the patients were treated with intravitreal ketorolac. After treatment, the patients were clinical examined with using optical coherence tomography(OCT)and fundus fluorescein angiography(FFA). And the clinical efficacy was observed. The corrected visual acuity, intraocular pressure and central retinal thickness of the cystoid macular area after cataract surgery were compared and analyzed before and after treatment in different periods(2 and 4wk, 3 and 6mo).

RESULTS:Comparing with before treatment, the leakage was significantly reduced at the FFA after intravitreal ketorolac for the treatment of chronic cystoid macular edema. And the cystoid macular edema in patients regressed. At the same time, the corrected visual acuity was significantly increased(P<0.05), and the intraocular pressure was significantly improved(P<0.05), and the average macular thickness was significantly reduced(P<0.05). The difference was statistically significant.

CONCLUSION:Intravitreal ketorolac for the treatment of chronic cystoid macular edema after cataract surgery has a good clinical efficacy. There is a important clinical significance.
