      Ultra-wide optical coherence tomography angiography in diabetic retinopathy

      Background: To implement an ultra-wide optical coherence tomography angiography imaging (UW-OCTA) modality in eyes with diabetic retinopathy (DR) with the aim of quantifying the burden of microvascular disease at baseline and subsequent clinic visits. Methods: UW-OCTA was implemented on a 1,060 nm swept source (SS) OCTA engine running at 100 kHz A-line rate with a motion tracking mechanism. A montage scanning protocol was used to capture a 100-degree field of view (FOV) using a 4×4 grid of sixteen total individual 6×6 mm 2 scans. Typical OCTA images with a FOV of 3×3, 6×6 and 12 ...

      How OCT angiography is improving our view of diabetic retinopathy

      The Early Treatment Diabetic Retinopathy Study (ETDRS) established and refined the current clinical grading of diabetic r etinopathy that retina specialists use as an adaptation of the Modified Airlie House Classification. The parameters of the grading system rely primarily on identifying somewhat indirect signs of microvascular ischemic disease that include retinal hemorrhages, venous beading, intraretinal microvascular abnormalities or preretinal neovascularization. However, identifying indirect signs of microvascular disease is fraught with challenges in ensuring reproducibility among different observers and operators, which may introduce error into research or clinical settings. ETDRS made attempts to measure and minimize this variability and found that ...
