Two-year results of intravitreal triamcinolone acetonide injection for the treatment of macular edema due to central retinal vein occlusion.

We investigated intravitreal triamcinolone acetonide injection for the treatment of macular edema due to central retinal vein occlusion in 20 patients. Mean central macular thickness at 3 days, 1, 3, 6, 12, 18, and 24 months postoperatively was different than baseline. Visual acuity did not change. Intravitreal triamcinolone injection significantly improves short-term anatomy, but recurrences and steroid-related complications were noted in the longer term.
