Continued progression of diabetes and poor long-term glycemic control can also affect the eyes, leading to the development of diabetic retinopathy.
Diabetic retinopathy refers to a series of lesions caused by microvascular damage to the retina due to diabetes, and is one of the common complications of diabetes.
The cause of its emergence is mainly related to persistent hyperglycemia, but the pathogenesis is still unclear, such as persistent hyperglycemic environment, can lead to vascular retinal barrier damage, increased permeability, microvascular leakage, and in the late stages of the retinal neovascularization and fibrous proliferation, which ultimately leads to retinal microvascular cell changes. This can lead to vision loss and in severe cases, blindness.
Diabetes is also prone to a variety of ocular complications. For example, glaucoma, optic nerve atrophy, vitreous clouding, fundus hemorrhage and so on. Related to the years of diabetes, the longer the onset of diabetes, the more severe the eye damage caused. Stable blood sugar control slows the onset of eye disease. Poorly controlled blood sugar can advance the onset of eye disease.
Therefore, after the diagnosis of diabetes, it is important to pay attention to strict control of blood sugar to avoid the development and progression of complications. Patients need to pay attention and actively seek treatment.
