Diabetic Retinopathy

Diabetic retinopathy (DR) is a chronic, progressive eye disease that causes visual impairment and is characterized by damage to the retinal microvasculature due to long-term hyperglycemia and other diabetes mellitus (DM)-related abnormalities, such as hypertension and dyslipidemia. Diabetic retinopathy can lead to macular edema and, in severe cases, preretinal and vitreous hemorrhage or even retinal detachment. It is one of the common and serious microvascular complications of diabetes. In traditional Chinese medicine (TCM), diabetic retinopathy falls within the categories of “dim vision,” “cloudiness obscuring vision,” “sudden blindness,” and “blood filling the pupil,” among others.
