Evaluation of Retinal Vessel Diameter Measurement in Coronary Artery Disease

Abstract

Purpose: To examine the relationship between the stage of coronary artery disease (CAD) and retinal vessel diameters in patients with s table angina pectoris (SAP) and diagnosed with CAD. Material and Methods: Patients with a diagnosis of CAD are divided into 3 stages according to the results of coronary angiography. Stage 1) Normal coronary artery; stage 2) Non-critical narrowing of coronary arteries ( 0.05). In stage 1, the mean diameter of the retinal arteri oles was 119.77 ± 7.24, and the venules were 142.44 ± 7.10; 118.77 ± 6.69 um and 143.01 ± 6.67 in stage 2, 104.60 ± 5.17 and 144.73 ± 12.45 um in stage 3, respectively. There was a significant difference between stage 1-3 and stage 2-3 (P = 0.730; P
