01Diabetic patients

Abnormal blood sugar levels can damage small blood vessels throughout the body. The retina of our eyes, which is the film of the camera of the eye, is full of fragile small blood vessels, which can easily cause diabetic retinopathy during the course of diabetes.

Diabetic retinopathy, abbreviated as DRE, is caused by abnormal blood sugar that affects the function of small retinal blood vessels, leading to symptoms of bleeding, hypoxia, and angiogenesis. When unhealthy new blood vessels appear, heavy bleeding, also known as vitreous hemorrhage, is likely to occur.

Regular fundus examinations are like detailed inspections of camera film, and are of immeasurable importance in timely detection and prevention of the spread of lesions.

02 Hypertension patients

The effect of high blood pressure on blood vessels is like a high pressure in a water pipe, which can cause long-term damage to the pipe. Therefore, the blood vessels of patients with high blood pressure are also damaged during the long-term illness, affecting the integrity of the retinal blood vessels.

Patients with uncontrolled hypertension are likely to develop hypertensive retinopathy and branch retinal vein occlusion, which can also affect the health of the retina.

In addition, patients with high blood pressure may experience optic disc edema, and they also need to have their fundus examined to find out the cause.

03

Severe myopia

High myopia may also cause some fundus complications, endanger visual health and even cause blindness, such as retinal holes, retinal detachment, macular hemorrhage, macular holes, choroidal neovascularization, etc.

The survey found that retinal diseases related to high myopia have become the leading cause of irreversible blindness in adults in some areas of my country.

If your myopia is greater than 600 degrees (high myopia), it is best to have an eye fundus examination once a year.
