Early versus late intravitreal triamcinolone acetonide for macular edema associated with branch retinal vein occlusion.

Abstract

PURPOSE: To compare the effect of early versus late intravitreal injection of triamcinolone in patients with macular edema due to branch retinal vein occlusion (BRVO). METHODS: Twenty eyes of 20 patients with macular edema from BRVO, including 10 with duration after onset of or 3 months, improvements in visual acuity and foveal thickness, though apparent at 1 month, were not maintained at 3 and 6 months post-triamcinolone. CONCLUSIONS: Intravitreal triamcinolone is more effective in patients with BRVO who are treated earlier.
