Purpose: To report the clinical outcome of a patient receiving an intravitreal injection of triamcinolone acetonide as treatment of bilateral, long-standing, cystoid macular edema due to central retinal vein occlusion.
Methods: A 70-years-old patient suffering from bilateral central retinal vein occlusion for 2 years and 1.5 years, respectively, received transconjunctivally an intravitreal injection of 25 mg of crystalline triamcinolone acetonide in each eye, with 10 weeks between injections.
Results: During the follow-up period of 4 months (OD) and 6 weeks (OS), respectively, visual acuity increased from 0.05 to 0.25 in his right eye and from 0.125 to 0.25 in his left eye. Fluorescein angiography showed a decrease of fluorescein leakage in the macular area.
Conclusions: Intravitreal injection of triamcinolone acetonide may be a therapeutic option for long-standing cystoid macular edema due to central retinal vein occlusion.
