How Does Diabetes Affect Your Eyes?


Diabetes is one of the most common diseases of modern society. It is a chronic condition that causes a disorder of the metabolism of fats, protein and carbohydrate, and which main characteristic is the increased levels of sugar (glucose) in the blood.

Diabetics have increased levels of glucose because their bodies cannot transfer it into cells. In spite of many prejudices, diabetics can perform all life activities normally, thereby denying the myth that they have many limitations.

Examples are public figures with diabetes like actors Halle Berry and Tom Hanks and footballer Nacho Fernandez. 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 for daily insulin injection in the body.

The second is the Type 2 diabetes that usually affects adults, but in recent years it appears in teenagers and young adults due to excessive weight gain.

In this type of diabetes, the pancreas usually produces insulin, but the amount is not sufficient enough for the organism or cells are resistant to insulin.

The symptoms of diabetes occurrence are: increased thirst, frequent urination, weight loss, blurred vision and more.

Diabetes can cause eye damage as a consequence of prolonged elevated blood sugar levels. It damages the blood vessels of the retina and causes bleeding of the retina, swelling and fatty deposits especially in the center for clear vision, and it can also create new blood vessels because it causes bleeding inside the eye. This condition is called diabetic retinopathy.

The method of choice for the treatment of diabetic retinopathy is laser photocoagulation of the retina. In recent years, great success is achieved by the application of so-called anti-VEGF therapy which causes a decrease in the swelling of the retina, and prevents the creation of new blood vessels in the posterior segment of the eye that is caused by diabetes.

In certain cases where the disease is at an advanced stage, when there are many blood vessels created, bleedings into the vitreous occur which are accompanied by detachment of the retina, the only way of treatment is the surgery called vitrectomy.

It is a one-day intervention that is performed under local anesthesia where the patient feels no pain and can go home immediately after the surgery.

Also, patients with this condition who have a diopter or cylinder are suitable for laser correction of diopters, in cases where the diabetes has not made changes in the eye.

The technology is so advanced, that in patients who have diabetic retinopathy they implant the latest intraocular lenses that remove their diopter.

If you are a diabetic, it is recommended to go for examination by an ophthalmologist once a year. If you still feel sharp reduction of vision, see like through haze, flies emerge or have a visual field defect you just have to come for an examination because changes in the eye can advance without a reduction in vision.
