Early versus Late Intravitreal Triamcinolone Acetonide for Macular Edema associated with Branch Retinal Vein Occlusion

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.
