Etiology - Diabetic retinopathy is caused by damage to the retinal blood vessels because of high blood sugar. People at risk for diabetic retinopathy are those who either already have diabetes or are likely to develop diabetes.
Symptoms - Blurry/cloudy vision, dark spots in central vision, difficulty seeing in low light, and sudden vision loss.
Details - Diabetic retinopathy ranges from mild to proliferative and occurs when high blood sugar levels weaken and disrupt the retinal blood vessels, which can lead to a myriad of blood flow constraints within the eye. If left untreated, diabetic retinopathy can lead to vision loss and even blindness.
Treatment - Especially if detected early, diabetic retinopathy can be treated and its adverse symptoms largely reversed. Treatment options can include general healthy lifestyle improvements, tight monitoring of blood sugar/cholesterol levels, and, if severe enough, various surgical options.
