Symptoms can include: Sudden loss of vision in one or both eyes Retinopathy of prematurity — An ophthalmologist examines the inside of the eye for abnormalities. In this test, a fluorescent dye is injected into the bloodstream, often into an arm vein. However, if you experience one or more of these symptoms, contact your ophthalmologist for a complete exam. Good management will help delay the development of retinopathy. After 15 years of having diabetes, 98 percent of those with type 1 diabetes and 78 percent of those with type 2 have some degree of retinal damage. Premature and low-birth-weight infants should be screened for retinopathy of prematurity if they: Are born at less than 36 weeks of gestation Weigh less than 4 pounds 6 ounces at birth GOP can be caused by or get worse from inadequate or too much oxygen after birth.

DBE is the most common cause of vision loss among people with diabetic retinopathy. Diabetic Retinopathy begins prior to any outward signs of disease being noticed.  These unstable blood vessels cause frequent minor bleeding. A more advanced form of diabetic retinopathy, called proliferative diabetic retinopathy, may lead to scars that decrease vision. Late-stage diabetic retinopathy symptoms include: Diabetic retinopathy is an eye disease caused by complications of diabetes.
