hypertensive retinopathy

Retinopathy

Retinopathy is a non-inflammatory disease of the retina, the membrane lining the back of the inner eye. This membrane is responsible for converting focused light images into electrical messages which are sent to the brain. Symptoms of retinopathy include sudden loss or decrease in vision or vision field, flashes of light or floating spots, all of which should prompt an immediate appointment with an eye care specialist. The most common cause of retinopathy is diabetes, causing damage to the blood vessels of the retina. There is also hypertensive retinopathy, caused by damage to retinal arteries related to high blood pressure. Sickle cell anemia can also adversely affect retinal blood vessels, as can prolonged sun exposure and certain drugs. Regular eye examinations can reveal any of these conditions and initiate a favorable plan of treatment.
