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]
The gold standard blood sugar test is the HbA1C test. Many studies have suggested that lowering HbA1C levels in someone with elevated HbA1C levels can lower the incidence and progression of retinopathy. Fortunately, blood sugar control can have benefits beyond just the eye. A primary care physician can help with blood sugar control strategies.
The causes of macular edema are numerous and different causes may be inter-related. It is commonly associated with diabetes.Chronic or uncontrolled diabetes type 2 can affect peripheral blood vessels including those of the retina which may leak fluid, blood and occasionally fats into the retina causing it to swell.
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.

A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
Diabetic angiopathy is a form of angiopathy associated with diabetic complications. [1] While not exclusive, the two most common forms are diabetic retinopathy and diabetic nephropathy, whose pathophysiologies are largely identical. Other forms of diabetic angiopathy include diabetic neuropathy and diabetic cardiomyopathy. [2] [3]
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.
