Purpose: To evaluate early changes after the first antivascular endothelial growth factor injection for macular edema secondary to diabetic retinopathy and retinal vein occlusion and the relationship between longterm outcomes. Methods: The study enrolled patients who received anti-vascular endothelial growth factor injections for treatment-naive macular edema due to retinal vein occlusion and diabetic retinopathy. The central macular thickness was measured at baseline, post-injection day 1, week 2, and month 1, and at the last visit using spectral-domain optical coherence tomography. A good response was defined as a central macular thickness reduction of 0.001 for both). All patients with macular edema-retinal vein occlusion were good responders at post-injection day 1. All nongood responders at post-injection day 1 belong to the macular edema-diabetic retinopathy group (n=16.50%). The rate of hyperreflective spots was higher in nongood responders than in good responders of the macular edema-diabetic retinopathy group (p =0.03). Of 42 (2.4%) total good responders, one had a central macular thickness 350 mu m, whereas 5 (31.2%) of 16 total nongood responders had a central macular thickness >350 mu m at the last visit (p=0.003). Conclusion: The longterm anatomical outcomes of macular edema secondary to retinal vein occlusion and diabetic retinopathy may be predicted by treatment response 1 day after antivascular endothelial growth factor injection.
