How Does Diabetes Affects the Eyes


The disease

Diabetes is one of the most common diseases of modern society. It is a chronic condition where there is a disorder of fat metabolism, protein and carbohydrate, and where the main feature is the increased value of sugar (glucose) in the blood.

Diabetics have elevated glucose because their bodies can not carry it into cells. In spite of many prejudices, diabetics can carry all life activities normally, thus denying the myth that they have many limitations. Examples are public figures with diabetes, actors Halle Berry and Tom Hanks and midfielder Nacho Fernandez.

Types of diabetes

There are two main types of diabetes: Type 1 diabetes which occurs at any age, but most often in children, teenagers or young adults. In this type of diabetes the pancreas produces little or no insulin, and therefore creates a need daily insulin release in the body. The second is that Type 2 diabetes usually affects adults, but in recent years appears in teenagers and young adults due to excessive weight gain. In this type of diabetes, the pancreas often produces insulin, but the amount or is not sufficient for the organism or the cells are resistant to insulin. Symptoms of occurrence of diabetes are: increased thirst, frequent urination, weight loss, blurred vision and more.

Diabetes and eyes

Diabetes can cause eye damage due to prolonged elevated blood sugar. It damages blood vessels of the retina, causing bleeding in the retina, swelling and fatty deposits especially in the center of clear vision, creating new blood vessels that cause the bleeding inside the eye. This condition is called diabetic retinopathy.

The choice of method for the treatment of diabetic retinopathy is laser retinal photocoagulation. In recent years, great success is achieved by the application of so-called anti-VEGF therapy causes a decrease in the swelling of the retina and prevents the creation of new blood vessels in the posterior segment of the eye, caused by diabetes. In certain cases where the disease is at an advanced stage, the only way of treatment is surgery called a vitrectomy. It’s a one-day intervention is performed under local anesthesia, the patient feels no pain, and after the procedure is free to go home.

If you are diabetic, it is recommended once a year to go to your ophthalmologist for examination. If you feel big reduction of vision or your vision is foggy, you should immediately visit your doctor, because changes in the eye can advance even without a reduction in vision. The ophthalmologist will make detailed examinations and properly treat the eye.
