Comparison between Optical coherence tomography Angiography and fundus Fluorescein Angiography in cases of Diabetic Maculopathy

Abstract

Background: Diabetic macular edoema (DME) in industrialised nations has become the most common cause of vision loss. The major cause of serious vision impairment in diabetes individuals is also diabetic macular ischemia (DMI). It is also one of the world's top causes of avoidable blindness, as the WHO states. The objective of this research was to evaluate the state of a capillary bed in diabetic maculopathy in the macular region and the connection between findings with OCT-Angiography and Fundus Fluorescein angiography. Methods: This research consisted of 40 eyes of 25 individuals aged 49 to 70 years with a clinically significant maculo-diabetic edoema as determined by the Early Treatment Diabetic Retinopathy (ETDRS) study without additional eye conditions. Outcomes and conclusion: This research shows the angiographical characteristics of OCT diabetic retinopathy. Some of their benefits over fluorescence angiography include the fast acquirement time, lack of requirement for an intravenous dye, the detection of tiny neovascular tufts and regions of capillary drop-out not masked by leaking. This technique may be helpful for regular diabetic retinopathy monitoring. It has limited field of vision, relatively poor resolution and difficulties identifying micro-aneurysms over a wide region. The lack of the retinal peripheral technology for measuring its vascular health is also a significant barrier to the adoption of OCT-A as the only means of evaluating diabetic retinopathy patients.
