  • Description: PURPOSETo 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.METHODSThe 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 ≥10% on post-injection day 1. Patients were reassessed at the last visit with regard to treatment response on post-injection day 1 based on the favorable anatomic outcome defined as a central macular thickness <350 µm.RESULTSIn total, 26 (44.8%) patients had macular edema-retinal vein occlusion and 32 (55.2%) had macular edema-diabetic retinopathy. The mean follow-up time was 24.0 (SD 8.5) months. A statistically significant decrease in the central macular thickness was observed in both patients with macular edema-retinal vein occlusion and macular edema-diabetic retinopathy after antivascular endothelial growth factor injection therapy (p<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 µm, whereas 5 (31.2%) of 16 total nongood responders had a central macular thickness >350 µm at the last visit (p=0.003).CONCLUSIONThe 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.
