Alert To The Dangers Of Diabetes On The Eye

　Diabetic retinopathy is a serious complication of diabetes, it is an important cause of blindness in diabetic patients increased today, diabetic eye disease to strengthen the prevention of blindness has become a top priority.

In our Eye Center, almost every day due to diabetic retinopathy and the need for surgery patients. In the process of diagnosis and treatment of these patients, found a considerable number of patients do not know the dangers of diabetes on the eye, there are more patients do not know diabetes can cause blindness. In addition, there are many patients know the dangers of diabetes, but because of work requirements, or luck, not good control of blood glucose and regularly check the eyes, only to medical treatment such as retinal hemorrhage, retinal damage results to the most serious of which is difficult to save.

Definition of diabetic retinopathy

Diabetic patients showed abnormal glucose metabolism, glucose increased. Diabetes, high glucose can damage retinal blood vessels, causing blood vessels atresia, retinal hypoxia, which occurs retinal microaneurysms, edema, exudation, hemorrhage, neovascularization, and vitreous proliferative lesions and a series of pathological changes, known as diabetic retinopathy lesions.

The dangers of diabetes on the eye

● diabetic retinopathy can cause blindness in the affected eye. The risk of diabetic blindness is 25 times normal.

● the development of diabetic retinopathy is hidden, when the patient was decreased vision, often disease is already advanced.

In the course of disease development, the early patients have no obvious symptoms until the patient was decreased vision, often the disease has progressed to a very serious stage, when most patients have lost the best timing of treatment. When the development of diabetic eye disease to a certain stage, the eye disease can not be reversed. A large number of studies have shown that diabetes leads to blindness prevention is the best way to preventive treatment. In order to receive timely treatment, the most effective way is to regularly check the eyes of people with diabetes, so patients had no obvious symptoms that doctors can find disease early and provide timely preventive treatment. Only regularly check the eyes, early detection, early treatment can prevent blindness caused by diabetes.

● Diabetic retinopathy is often late in the course of diabetes (5-10 years) appeared early patients have no symptoms, so often ignored. When vision loss occurs, they often have irreversible disease.

Empirically, patients with diabetes if blood glucose, blood pressure and lipids are controlled well, life does not note that many patients five years after the emergence of retinopathy; if blood sugar, blood pressure and other indicators of control in general, then 10 to 15 years retinal lesions may occur. I have seen a lot of blood sugar, blood pressure, lipids are well controlled diabetes, duration> 20 years, the fundus remains well. This shows the occurrence of diabetic eye disease and blood glucose, blood pressure and lipid control and other indicators of quality-related; the other hand, suggesting that diabetic eye disease is closely related to the occurrence and course of disease. It is noteworthy that many patients diagnosed with type 2 diabetes prevalence of diabetes do not know how long, so once diagnosed, it should immediately check the eyes.

Prevent diabetic blindness

A large number of studies have shown that diabetic retinopathy if early diagnosis and treatment, 90% of patients can prevent blindness. A large number of the root causes of diabetes ultimately blindness is to ignore the eye examination and treatment. Early detection and laser treatment can significantly reduce the risk of diabetic retinopathy of blindness. Laser treatment can maximize the retention vision, but can not make the loss of visual acuity.

All diabetic patients should be periodically by an ophthalmologist for eye exams, to get timely treatment to prevent diabetic retinopathy caused by the loss of vision.

Community physicians should be in an appropriate manner, to give the patient the correct and timely advice and guidance; awaken awareness of prevention of blindness in diabetic patients to enable them to recognize the risk of diabetes lead to vision loss and early diagnosis and timely treatment of the importance of eye protection; so that they receive timely examination and treatment, which is essential to improve patients' quality of life.

Reasonable arrangements for eye examination in patients with diabetes

Diabetes check at least 1 eye. For the already diagnosed with diabetic retinopathy patients, the need to increase the number of checks per year, specific times to listen to medical advice.

When patients first diagnosed with diabetes, the eye should be checked in accordance with the following tips:

● <30-year-old patient, diagnosed with diabetes five years must be eye examination.

● ≥ 30-year-old patient, diagnosed with diabetes in a few months, the eye should be checked, because it may have been diagnosed in patients before diabetic retinopathy has already happened.

● For gestational diabetic women, the first three months of pregnancy should be closely observed, and at 3 months of pregnancy during the fundus examination 1. Because diabetic retinopathy during pregnancy may develop rapidly.

● If you have diabetes-related kidney failure or amputation history, or history of diabetes> 10 years, your eye doctor should be immediately eye examination, as it is at high risk of visual impairment in diabetes.

If after following the case of diabetes, should go to the hospital for eye examination:

● changes in visual acuity of one or both eyes.

● visual changes for several days.

● there has nothing to do with blood sugar changes in visual acuity reduced.

Common Mistakes of diabetic retinopathy

● Diabetes good vision, no need to check eyes.

Many patients do not know the dangers of diabetes on the eyes, blindness prevention of diabetes knowledge so seriously, that their eyes no problem, while ignoring the dangers of diabetes on the eye hidden.

● such as decreased vision and then go to an ophthalmologist.

As mentioned earlier, when diabetics are decreased vision, often very severe retinopathy, and difficult to reverse. Only regularly check the eyes to early detection and early treatment to prevent the disease worse.

● have done laser treatment, the eyes should be no problem.
Diabetic retinopathy is gradually increased as the duration, even after laser treatment or vitreous surgery can not once and for all, should regularly check the eyes, a complementary treatment.

● fear more of visual acuity after retinal laser treatment decreased.

Retinal laser treatment of retinopathy can only further increase the control, prevent complications, can not reverse the disease, it is difficult to restore vision already lost. Decreased vision after laser treatment, even if temporarily unable to control, disease control and prevention of retinal blindness is extremely important.
