| Popis: | Purpose Diabetic macular ischemia is a vision-threatening complication of diabetes mellitus. Early detection of ischemic changes can preserve the vision. The aim of the study was to detect the early macular ischemic changes in patients with no diabetic retinopathy (NDR), using optical coherence tomography angiography, and to correlate these changes with the best-corrected distance visual acuity (BCDVA). Patients and methods A case–control study was conducted to compare 30 diabetic eyes with NDR with 30 healthy control eyes. The glycemic control was determined by glycosylated hemoglobin level less than 6.5%. The diabetic group was further subdivided into those with normal BCDVA and those with decreased BCDVA. The outcome measures included BCDVA and optical coherence tomography angiography features. Results Compared with controls, the diabetics with decreased BCDVA were found to have significantly thinner central macular thickness (P |
