Purpose: To investigate the foveal avascular zone (AVZ), superficial and deep foveal and parafoveal vesseldensity (VD) changes related to diabetic retinopathy. Methods: Forty-nine type 2 diabetes mellitus (DM) and 45 healthy control subjects were included in this study. The demographic data (age and sex), disease duration, and level of glycated hemoglobin were collected. SuperficialVD (%), superficial AVZ area (mm2), deep VD (%) and deep AVZ area (mm2) were evaluated via opticcoherence tomography angiography. Results: Superficial AVZ was 0.438 ± 0.05 mm2 in the DM group, 0.246 ± 0.022 mm2 in the control group (p< 0.001). Deep AVZ was 0.732 ± 0.06 mm2 in the DM group, and 0.342 ± 0.022 mm2 in the control group (p< 0.001). Superficial foveal VD was 29.45 ± 0.76 mm2 in the DM group, and 34.86 ± 0.75 mm2 in the controlgroup (p < 0.001). Deep foveal VD was 24.85 ± 1.08 mm2 in the DM group, and 33.47 ± 0.56 mm2 in the controlgroup (p < 0.001). Conclusions: In this study, we demonstrated an enlargement in the foveal AVZ along with a reduction in thevascular density of the superficial and deep capillary network in the foveal and parafoveal area using optic coherencetomography angiography in patients with nonproliferative diabetic retinopathy. This technique can beused to monitor the progression of the disease and to evaluate the response to treatment.

Purpose: The aim of the present study is to evaluate the effects of uncomplicated cataract surgery on microvascular structure of fovea, parafovea, optic disc, and peripapillary area with optical coherence tomography angiography (OCTA). Methods: The study included 53 eyes of 53 patients, who undergone uncomplicated cataract surgery. The day before cataract surgery and at the 1st week, 1st month, 3rd month after surgery, best-corrected visual acuity, foveal avascular zone, acircularity index, superficial and deep foveal density, superficial and deep parafoveal density, central macular thickness, peripapillary retinal nerve fiber layer thickness value, and peripapillary vascular density were measured with OCTA. Results: The mean age of the patients was 62.1 ± 7.2 years (range, 42-69 years) and the sex of the patients was 25 male and 28 female. The foveal avascular zone value was decreased compared to the preoperative value (p < 0.05). There was no significant change in acircularity index postoperatively (p > 0.05). There was a significant increase in superficial and deep foveal density and superficial and deep parafoveal density (p < 0.05). According to preoperative period, peripapillary retinal nerve fiber layer and inside disc capillary density of optic disc increased significantly (p < 0.05). There was no significant change in peripapillary vascular density postoperatively (p > 0.05). Conclusions: Changes in the vascular density of the retina were detected with OCTA in eyes without ocular or systemic disease, which underwent uncomplicated cataract surgery. In the postsurgical period, OCTA provides important information in the evaluation and follow-up of these changes.
