Diabetic Eye disease

Diabetic Eye diseaseDiabetic retinopathy

What is it?

Diabetes is a pathology that affects the body's ability to produce insulin effectively to control blood sugar levels. Excessive glucose in the blood for a long time can cause damage to various parts of the body, including the heart, kidneys, blood vessels and small blood vessels in the eyes.

Over time, diabetes damages the blood vessels in the retina. Diabetic retinopathy occurs when these tiny blood vessels leak blood and other fluids. This causes the retinal tissue to swell, resulting in cloudy or blurred vision. The condition usually affects both eyes. The longer a person has diabetes, the more likely they will develop diabetic retinopathy.

People who have bad blood sugar control, pregnant women, people with high blood pressure and high levels of fat, or both, have more risk of developing this disease.


When blood sugar levels are too high for extended periods of time, it can damage capillaries (tiny blood vessels) that supply blood to the retina. Over time, these blood vessels begin to leak fluids and fats, causing edema (swelling).

An examination of the fundus of the eye is essential for its diagnosis. In diabetics changes in blood sugar levels often cause blurred vision or changes in focus due to changes in the hydration of the eye. This should not be confused with diabetic retinopathy.

We correct eye diabetes in Alicante through surgery


Surgery is the main treatment to combat diabetic retinopathy.
Laser eye surgery creates small scars on the retina where there are abnormal blood vessels. This process is called photocoagulation and is used to prevent vessels from seepage or to reduce the size of abnormal vessels. In many cases this procedure can be complemented with the injection of substances to diminish the inflammation or to reduce the growth of those vessels.

In cases with internal bleeding or retinal detachment, the surgery called vitrectomy is the only solution.
