Abstract

Diabetic retinopathy is typically asymptomatic in the early stages. Diabetic macular edema is an important manifestation of DR that can be seen at anystage of diabetic retinopathy, as early as NPDR, although it is more common in moresevere stages
Fluorescein angiography (FA) is the gold standard tool for visualizing retinal vasculaturethat has been used for over more than 30 years to assess chorioretinal disorders. Fluorescein angiography is the best way to diagnose retinal ischemiawhich represents retinal non-perfusion or capillary dropout.Ultra-wide-field (UWF) photography is described by the Diabetic RetinopathyClinical Research Network (DRCRnet) as fundus photography having a field of view of atleast 100 degrees.
AIM OF THE WORK:
The aim of this work was to evaluate the relation between macular edema andperipheral retinal ischemia in patients with diabetic retinopathy using Spectral Domain Optical Coherence Tomography (OCT) and Ultra- Wide Field Fluorescein angiography (UWFA) imaging techniques.
SUBJECTS:
This study was conducted on 50 eyes of diabetic patients diagnosed clinically, by fluorescein angiography and optical coherence tomography as having diabetic retinopathy with macular edema.
