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 ≤3 months and 10 with duration of >3 months, were treated using a single intravitreal triamcinolone injection (4 mg/0.1 ml). Best-corrected visual acuity and foveal thickness by optical coherence tomography were measured 1, 3, and 6 months post-injection. Results: In patients that received treatment after a disease duration of ≤3 months, visual acuity and foveal thickness significantly improved from baseline over 6 months of follow-up. However, in those with a duration of > 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.
