Fundus fluorescein angiography is one of the leading tools for the early detection of DR, however it is an invasive procedure. OCTA has been nominated as a non-invasive tool for the early detection of DR. Optical Coherence Tomography(OCT) and Optical Coherence Tomography Angiography (OCTA) for the quantitative assessment of choroidal vascular density map correlated with choroidal thickness in normal individuals and in diabetic patients with and without diabetic retinopathy (DR).
Patients and Methods: This study included 64 eyes. The diabetic and control groups were recruited from an internal medicine clinic at Misr University for Science and Technology Hospital and asked to participate in this study. This study was designed as an observational and crosssectional study in the period from 12/2017 to 12/2019.
Results: There was a decrease in choroidal thickness and vascular density in patients with diabetes.
Conclusion: Our study suggests that OCTA can identify preclinical DR prior to the manifestation of clinically apparent retinopathy. Our ?ndings highlight the potential role of OCT-A in the monitoring and quantification of choroidal vascular alterations in diabetes.
