Vision loss, diabetes is at work

Letter from the reader.

hzh {display: none; }  我父亲患有糖尿病多年,不久前他发现自己看东西越来越模糊,眼前好像有一小块东西挡住视线。At first, we thought that it was normal for the elderly to be old and could not see things. I didn’t expect to go to the hospital for examination. The doctor said that it was a retinopathy caused by diabetes. What should I do if I have this disease?

Can vision be restored?

  As a kind of endocrine and metabolic disorder, diabetes is involved in many organs of the body. Among them, eye diseases are a common complication of diabetes.

Diabetic eye diseases mainly include cataracts, glaucoma and retinal resection, which can impair the vision of diabetic patients and even lead to blindness.

  Retinopathy is the most common form of diabetic eye disease and one of the most important blinding eye diseases.

The retina is a light-sensitive tissue located at the back of the eyeball. Hyperglycemia can cause swelling and even leakage of blood vessels in the retina. Abnormal neovascularization will grow on the surface of the retina, causing bleeding and affecting vision.

This retinal defect often occurs in both eyes.

  Diabetic retinopathy is generally divided into a non-proliferative phase and a proliferative phase.

The non-proliferative phase is the early stage of diabetic retinopathy. The patient’s appearance will become blurred. The most common manifestation is difficulty in reading or driving, and vision may occur once and for all.

  If the neovascularization forms on the surface of the retina, it means that the retina retina enters the late stage, that is, the proliferative phase. The blood clot implanted by the retinal hemorrhage seems to be blocked by a piece of things in front of the eye. It may not be serious at one time, and disappears after a few hours.However, in the next few days or weeks, there will usually be a more severe retinal hemorrhage, making the vision more and more blurred.

  As long as diabetes, whether type I or type II, there is a risk of retinal complications, and the longer the diabetes, the risk of developing an eye disease.

In the United States, approximately 40% to 45% of people with diabetes are associated with varying degrees of diabetic retinopathy.

  At the beginning of the retinal lesions, there may be no symptoms, so the diabetic patients should have a full fundus fundus examination at least once a year, and the lesions should be found at the same time.

  Pregnant women with diabetes during pregnancy are also prone to retinopathy.

In order to protect eyesight, it is best for pregnant women with diabetes to receive a full eye exam every month.

  The better the blood sugar level is controlled, the more it can delay the occurrence and development of the retina.

Therefore, diabetic patients should actively control blood sugar, monitor blood pressure regularly, and maintain healthy eating habits.

  Patients with initial diabetic retinopathy can effectively avoid a large amount of visual impairment as long as they can receive treatment in time.

At present, the main methods for treating diabetic retinopathy are laser photocoagulation, vitrectomy and other medical treatments such as anti-VEGF therapy.
