AIM: To evaluate the efficacy of retrobulbar injection of triamcinolone acetonide(TA)combined with 577nm laser macular grid photocoagulation for the treatment of cystoid macular edema.

METHODS: Fifty-eight cases(66 eyes)with cystoid macular edema caused by different diseases were recruited in this study. The included patients were treated with both retrobulbar injection of triamcinolone acetonide and 577nm laser macular grid photocoagulation. The best corrected visual acuity, macular thickness, fundus and intraocular pressure were observed in the 1wk, 1 and 3mo after the treatment in all of the included cases.

RESULTS: After treatment, all of the 66 eyes showed cystoid macular edema partially or completely subsided according to optical coherence tomography and fluorescence fundus angiography; 54 eyes(82%)visual acuity improved, 12 vision remained the same.

CONCLUSION: Retrobulbar injection of triamcinolone acetonide combined with 577nm laser macular grid photocoagulation has good curative effect, simple operation procedure and rare complications in the management of cystoid macular edema.
