Abstract

Abstract : Purpose: To compare the changes in retinal perfusion on ultra–wide-field fluorescein angiography with the changes in diabetic retinopathy lesions observed on ultra–wide-field fundus color photographs after 3 monthly anti–vascular endothelial growth factor injections. Methods: Retrospective interventional cohort study analyzing the files of 14 patients with DR (18 eyes). UWF color photos and FA were analyzed at baseline (M0) and 1 month after the third anti-VEGF injection (M3). The main outcomes included the count of the number of red dots (microaneurysms, hemorrhages) and assessment of DR severity score (DRSS); the analysis of non-perfusion areas and disappearance or reappearance of arterioles or venules in the non-perfusion areas on FA. Results: Eighteen eyes of 14 diabetic patients, with mean age of 63 ± 5 years, were included. The DRSS score improved by at least one stage in 11/18 (61%) eyes. The mean number of red dots significantly decreased at M3 (n = 80 ± 85) compared with M0 (n = 139 ± 130) ( P < 0.0001). No reperfusion of arterioles or venules was observed in or around nonperfusion areas. Conclusion: After anti–vascular endothelial growth factor injections, the improvement in the DRSS score based on color fundus photographs can occur without retinal reperfusion on ultra–wide-field fluorescein angiography. Abstract : After three intravitreal anti–vascular endothelial growth factor injections, the severity of diabetic retinopathy on color fundus photographs improved, whereas no reperfusion occurred in the nonperfusion areas assessed on ultra–wide-field fluorescein angiography.
