Etiology - Diabetic retinopathy is caused by damage to the retinal blood vessels because of high blood sugar. People at risk are those who either already have diabetes or are likely to develop it.
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. It occurs when high blood sugar levels strain and weaken retinal blood vessels, which leads to disrupted blood flow in the eye. If left untreated, it can lead to partial vision loss and even blindness.
Treatment - If detected early, its negative effects can be largely reversed. Common treatments include general health improvements, tight monitoring of blood sugar/cholesterol levels, and, in severe cases, surgical options.
