    4. Quantification of diabetic macular ischemia using novel three‐dimensional optical coherence tomography angiography metrics

      Quantification of diabetic macular ischemia using novel three‐dimensional optical coherence tomography angiography metrics
      We applied three‐dimensional (3D) analysis to optical coherence tomography angiography (OCTA) to measure macular ischemia in eyes affected by non‐proliferative diabetic retinopathy (DR). A previously validated algorithm was applied to OCTA data in order to obtain 3D visualization of the retinal vasculature. Successively, a global thresholding algorithm was applied and two novel quantitative metrics were introduced: 3D vascular volume and 3D perfusion density. Two‐dimensional (2D) OCTA metrics ...

    8. Appearance of cysts and capillary non perfusion areas in diabetic macular edema using two different OCTA devices

      Appearance of cysts and capillary non perfusion areas in diabetic macular edema using two different OCTA devices
      The aim of this paper was to distinguish the appearance of cysts and non-perfusion areas (NPAs) in diabetic macular edema (DME) using two different Optical Coherence Tomography Angiography (OCTA) devices. In this study, patients underwent OCTA using the AngioVue XR Avanti Spectral Domain (SD) OCTA and the PLEX Elite 9000 Swept-Source (SS) OCTA. Foveal and extrafoveal regions of interest (ROI), defined as any area with an altered flow signal comparing ...

    9. OCTA characterisation of microvascular retinal alterations in patients with central serous chorioretinopathy

      OCTA characterisation of microvascular retinal alterations in patients with central serous chorioretinopathy
      Purpose This study aimed to describe the characteristics of microvascular retinal alterations in eyes with chronic central serous chorioretinopathy (CSC) employing optical coherence tomography angiography (OCTA) analysis. Methods We collected data from 472 eyes with chronic CSC from 336 patients who had OCTA obtained. Each OCTA image was graded by two readers to assess the presence of microvascular retinal alterations, including regions of vascular rarefaction/retinal hypoperfusion, enlargement of the ...

    10. Optical coherence tomography angiography in diabetes: A review

      Optical coherence tomography angiography in diabetes: A review
      Diabetic retinopathy is a common diabetes complication representing a heavy burden in terms of visual impairment and heath expenditure. Optical coherence tomography angiography is a relatively new imaging method and has proven to be a powerful tool in the analysis of diabetic retinopathy common features, including microaneurysms, intraretinal microvascular abnormalities, or neovascularization, as well as in research field, challenging the gold standard of fluorescein angiography. Many studies underlined the vascular ...
