Objectives: The aim of the present study is to evaluate the optical coherence tomography angiography (OCTA) images in patients with type 1 diabetes who have not been diagnosed with retinopathy. Materials and Methods: The study included 17 eyes of 11 patients with type 1 diabetes and 36 eyes of 18 healthy volunteers. Optical coherence tomography angiography images were evaluated for the presence of microvascular changes and measurement of foveal avascular zone (FAZ) area and vessel density (VD) measurements in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) were performed. Results: Optical coherence tomography angiography revealed microvascular changes in 7 of 11 type 1 diabetes cases. There was no significant difference between the FAZ measurements between the diabetic group and the control group at the SCP and DCP levels (p=0,647, p=0,874 respectively). There was also no significant difference in VD measurements between the diabetic group and the control group (p> 0.05). In diabetic patients who are not clinically diagnosed with diabetic retinopathy, retinal microvascular damage may occur. Optical coherence tomography angiography is a rapid, noninvasive, and safe imaging modality that is useful in the recognition of microvascular findings that develop at an early stage.
