Diabetes-induced retinopathy is usually not completely curable, but it can be controlled, improving symptoms and slowing progression. Diabetic retinopathy is a more common chronic complication of diabetes, which is a microvascular damage to the retina caused by diabetes, and is mainly characterized by blurred vision, diplopia, visual field defects, vision loss, and severe blindness. Although diabetic retinopathy cannot be completely cured, it can be controlled and prevented. Once the diagnosis of diabetes is confirmed, early strict control of blood glucose should be adhered to regular funduscopic examination, while actively managing blood pressure and blood lipids, can effectively prevent or delay diabetic retinopathy. After the diagnosis of diabetic retinopathy is confirmed, it is still necessary to actively control blood glucose, blood pressure and blood lipids, and medication (e.g. calcium hydroxybenzenesulfonate), laser treatment (e.g. retinal photocoagulation) and surgical treatment (vitrectomy) can be used to improve the symptoms. For retinopathy caused by diabetes mellitus, endocrinology consultation is recommended for further examination of the fundus and formulation of an appropriate treatment plan.
