摘 要:AIM:To analyze differences in ultra-widefield fluorescein angiography(UWFA)findings between dynamic and static images of eyes with diabetic retinopathy(DR).METHODS:This cross-sectional study included 28 eyes of 28 patients with DR undergoing UWFA.A series of UWFA images acquired from each patient were converted into a time-lapse video and used as a dynamic image.A single,clear,arteriovenous phase image was chosen as a static image.Non-perfusion index(NPI)and its correlation with vascular abnormalities in different zones were compared between dynamic and static UWFA imaging.RESULTS:NPI appeared to increase from the center to the far-periphery in both groups.Dynamic NPI was lower in the total retinal area(0.26 vs 0.29,P=0.009)and farperiphery(0.33 vs 0.36,adjusted P=0.042),which was contrary to the static NPI.Far-peripheral NPI was associated with intraretinal microvascular abnormality in the posterior area in both groups.CONCLUSION:Time-lapse dynamic UWFA imaging is a useful modality to differentially diagnose hypofluorescence in the most peripheral region.This modality could provide a reliable method for NPI measurement.
