    1. Do microvascular changes occur preceding neural impairment in early-stage diabetic retinopathy? Evidence based on the optic nerve head using optical coherence tomography angiography

      Do microvascular changes occur preceding neural impairment in early-stage diabetic retinopathy? Evidence based on the optic nerve head using optical coherence tomography angiography

      Aims To evaluate the microvascular and neural differences of the optic nerve head (ONH) between type 2 diabetes mellitus (T2DM) subjects and controls. Methods This was a cross-sectional observational study. One hundred and eight eyes of 108 T2DM subjects with or without diabetic retinopathy (DR) (54 preclinical DR and 54 mild-to-moderate DR) were included. Fifty-two eyes of 52 healthy subjects were included as controls. The 4.5-mm Angio Disc scan mode and the ganglion cell complex scan mode were performed with all participants using AngioVue software 2.0 of the optical coherence tomography angiography (OCTA) device. Results Regarding ONH radial ...

    2. Optical coherence tomography angiography findings of neurovascular changes in type 2 diabetes mellitus patients without clinical diabetic retinopathy

      Optical coherence tomography angiography findings of neurovascular changes in type 2 diabetes mellitus patients without clinical diabetic retinopathy

      Aims To evaluate the effect of early screening with OCTA in type 2 diabetes mellitus (T2DM) patients without clinical DR (NDR). Methods This was a cross-sectional case–control clinical study. Eighty-four eyes of 84 patients (44 T2DM and 40 control subjects) were included. Images were obtained using AngioVue software 2.0 of the OCTA device. Foveal avascular zone (FAZ) area, FAZ perimeter (PERIM), choriocapillary flow area (CCF), acircularity index (AI), foveal vessel density in a 300-µm-wide region around FAZ (FD), macular-associated vessel density (VD) and optic disc-associated capillary density (CD) were compared between the T2DM and control groups. In ...
