Intraretinal microvascular abnormalities (IRMA) are abnormalities of the blood vessels that supply the retina of the eye, a sign of diabetic retinopathy. [1] IRMA can be difficult to distinguish from and is likely a precursor to retinal neovascularization. One way to distinguish IRMA from retinal neovascularization is to perform fluorescein ...
Diabetic retinopathy (also known as diabetic eye disease) is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
The most common cause found in adults is diabetic retinopathy. Abnormal blood vessels can form in the back of the eye of a person with diabetes. These new blood vessels are weaker and prone to breaking and causing hemorrhage. [2] Diabetic retinopathy accounts for 31.5–54% of all cases of vitreous hemorrhage in adults in the United States. [1]
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Diabetes is the most common cause of retinopathy in the U.S. as of 2008. [4] Diabetic retinopathy is the leading cause of blindness in working-aged people. [5] It accounts for about 5% of blindness worldwide and is designated a priority eye disease by the World Health Organization. [6]

Cotton wool spots are typically a sign of another disease state, most common of which is diabetic retinopathy. [2] The irregularly shaped white patches are a result of ischemia , or reduced blood flow and oxygen, in the retinal nerve fiber layer , which is located in the distribution of the capillaries of the superficial layer of the retina.

Retinal vasculopathy with cerebral leukocencephalopathy and systemic manifestations (RVCL or RVCL-S, also previously known as retinal vasculopathy with cerebral leukodystrophy, RVCL; or cerebroretinal vasculopathy, CRV; or hereditary vascular retinopathy, HVR; or hereditary endotheliopathy, retinopathy, nephropathy, and stroke, HERNS) is an inherited condition resulting from a frameshift ...
