Can diabetes cause eye disease

Diabetes usually leads to eye diseases.

Long-term hyperglycemia can damage the microvessels of the eye. Sustained high blood sugar levels can make the blood vessel wall fragile and increase permeability, which can affect the normal blood supply and nutrient transport of the eye, resulting in retinal diseases. Damage to the microvessels on the retina can cause retinal hemorrhage, exudation, edema, etc., and in severe cases, vision loss or even blindness. In addition, diabetic patients are more likely to develop cataracts than ordinary people. High blood sugar can accelerate the clouding process of the lens, making cataracts appear earlier and develop more rapidly.

In order to prevent and reduce the occurrence and development of diabetic eye diseases, diabetic patients need to strictly control blood sugar, blood pressure, blood lipids and other indicators, regular eye examination, so as to detect problems early and timely treatment. At the same time, maintaining a healthy lifestyle, such as reasonable diet, moderate exercise, smoking, etc., is also very important to protect eye health.
