Areas of neovascularization (NV) in proliferative diabetic retinopathy (PDR) on ultrawide-field (UWF) fluorescein angiography (FA) were identified and compared with a simulated wide field (WF) swept-source OCT angiography (SS-OCTA) field of view (FOV) to determine whether the WF SS-OCTA FOV was sufficient for detection of NV in PDR.

To explore the distribution of non-perfusion area (NPA) on ultra-wide field fluorescein angiography (UWF FA) in proliferative diabetic retinopathy (PDR) and its relationship with the presence of neova...
Various imaging modalities are of significant utility in the screening, grading, treatment, and follow-up of the different stages of diabetic retinopathy (DR) and diabetic macular edema. Color stereog...
To classify retinal nonperfusion regions (NPR) in patients with diabetic macular edema (DME) and assess the relationship with severity of DME.
Threshold of retinal nonperfusion for the development of proliferative diabetic retinopathy (PDR) is unclear.
PURPOSE: To characterize the appearance of the far peripheral retina of normal eyes using ultra-widefield fluorescein angiography (UWFA). DESIGN: Prospective observational case series. ME...
To develop a database of the peripheral retinal circulation using ultra widefield fluorescein angiography (UWF-FA) imaging for the Optos COE platform. This database will serve as a quanti...
This interventional study will evaluate the retinal vascular dynamics associated with Intravitreal Aflibercept Injection (IAI) therapy in eyes with diabetic macular edema (DME) or macular ...
The purpose is to compare the efficacy of ranibizumab versus additional panretinal photocoagulation on diabetic neovascularization that is persistent despite previous treatment with panret...
Background: to evaluate the 3-month efficacy of a single dose of intravitreal bevacizumab on the progression of severe non proliferative diabetic retinopathy, proliferative diabetic retino...
Visualization of a vascular system after intravenous injection of a fluorescein solution. The images may be photographed or televised. It is used especially in studying the retinal and uveal vasculature.
Disease of the RETINA as a complication of DIABETES MELLITUS. It is characterized by the progressive microvascular complications, such as ANEURYSM, interretinal EDEMA, and intraocular PATHOLOGIC NEOVASCULARIZATION.
Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy.

Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
A TIE receptor tyrosine kinase that is found almost exclusively on ENDOTHELIAL CELLS. It is required for both normal embryonic vascular development (NEOVASCULARIZATION, PHYSIOLOGIC) and tumor angiogenesis (NEOVASCULARIZATION, PATHOLOGIC).
Diabetes is a lifelong condition that causes a person's blood sugar level to become too high. The two main types of diabetes are: type 1 diabetes type 2 diabetes In the UK, diabetes affects approximately 2.9 million people. There are a...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
