Diabetes experts say that in fact, diabetes itself does not cause too much harm to the human body, the risk factors of diabetes exist in diabetes, which will cause other complications, diabetic retinopathy is one of them, its occurrence is irreversible. Therefore, diabetic patients should be careful with retinopathy.

Diabetes is a disorder of glucose metabolism that affects the organs and blood vessels of the whole body, which can cause many complications. Among them, diabetic retinopathy is a common and serious ocular complication of diabetes mellitus, with retinal microvascular damage as the most significant feature. It is the first or second leading cause of blindness in European and American countries.

Studies have shown that the occurrence and development of diabetic retinopathy are closely related to the course of diabetes, and its incidence increases with the prolongation of the course of diabetes. With the improvement of living standards and the prolongation of life span of diabetic patients, the incidence of diabetes in China also has a trend of increasing gradually. The incidence of diabetic retinopathy has nothing to do with gender and age, but it is closely related to the course of diabetes. Fundus lesions increase with the duration of diabetes, and the incidence rate increases gradually. When the time is high or hyperlipidemia, the incidence rate of fundus lesions will increase significantly.

Diabetic patients should be careful of retinopathy. The occurrence and development of diabetic retinopathy is a long clinical process. According to blood glucose level, blood glucose control, other systemic complications and individual differences, the speed of development of diabetic retinopathy is different. Diabetic retinopathy is characterized by microaneurysms, bleeding spots, hard exudates, cotton wool spots, venous Beaded retinal microcirculation abnormalities, and macular edema. Extensive ischemia can cause retinal or optic disc neovascularization, retinal hemorrhage, vitreous hemorrhage and tractive retinal detachment. The occurrence of these lesions can cause serious visual impairment.
