Oct 11, 2024 · Fluorescein angiography or OCT angiography helps your doctor see what is happening with the blood vessels in your retina. Fluorescein angiography uses a yellow dye called fluorescein, which is injected into a vein (usually in your arm).

Posterior pole structural OCT had the best detection rate for NV, and B-scan OCTA showed the most potential for objective monitoring of disease after treatment. This study demonstrates the utility of novel multimodal imaging in the daily management of patients with PDR.

Jun 29, 2020 · Optical coherence tomography (OCT) is a noninvasive imaging technique well established for DME but less used to assess neovascularization in PDR. Developments in OCT imaging and the introduction of OCT angiography (OCTA) have shown significant potential in …

Feb 3, 2025 · Purpose: To evaluate the relationship between diabetic retinal neurodegeneration (DRN), as quantified by optical coherence tomography (OCT), to the development of diabetic retinopathy (DR), progression of DR, and development of proliferative DR (PDR).

Oct 11, 2021 · Proliferative diabetic retinopathy (PDR) is a major cause of blindness in diabetic individuals. Optical coherence tomography (OCT) and OCT-angiography (OCTA) are noninvasive imaging techniques useful for the diagnosis and assessment of PDR.

Feb 14, 2025 · On OCT, measurements that elucidate diabetic retinal neurodegeneration may precede microvascular changes characteristic of the disease, allowing for earlier detection and treatment. Namely, thinner macular ganglion cell-inner plexiform layer thicknesses at baseline were associated with DR progression and PDR development in this study .

To assess the real clinical utility of widefield OCT angiography (WF-OCTA) for detecting retinal neovascularization (RNV) in eyes with proliferative diabetic retinopathy (PDR).

Purpose: To present the routine use of OCT and OCT angiography (OCTA) for the objective diagnosis and monitoring of proliferative diabetic retinopathy (PDR). Design: Retrospective, observational case series. Participants: Patients with diabetic retinopathy imaged using a standardized PDR protocol.

OCT angiography (OCTA) is a novel technology that produces images of retinal and choroidal vascular flow without dye injection. OCTA images are acquired by detection of the decorrelation signal generated between multiple successive OCT scans taken at high speed.

OCT showing center-involving diabetic macular edema Proliferative diabetic retinopathy (PDR) PDR happens after the diabetic angiopathy causes ischemia that is severe and longstanding enough to lead to neovascularization. PDR is really bad news for the eye!
