How does diabetes affect your eyes and what can you do about it?

diabetes It has become a public health problem in the world. In Peru, about 1.4 million people over the age of 15 suffer from this disease, according to the Ministry of Health (Mine). Lima, Arequipa and Piura represent more cases due to more modern lifestyles and approaches to processed products.

This disease causes increased levels of glucose (blood sugar). From the diagnosis it is important that the patient maintains proper control as it may include other organs, such as the eyes, kidneys and the brain. This was explained by Dr. Héctor Palacios, a specialist of the ophthalmologic vision clinic.

"Diabetes directly affects the eyes and affects the various areas of this organ, but to a greater extent to the retina. Lesium in this layer generates diabetic retinopathy, ocular clots that occur when high blood sugar levels cause damage to retinal blood vessels, "he said.

According to the World Health Organization (WHO), 1% of the world's leading causes of visual impairment are caused by diabetic retinopathy.


Diabetic retinopathy is an initial symptom of small lesions in the retinal veins of the retina, microanurism, microemorrhage and even the inflammation of the macula, the central part of the retina that allows reading and detail details. On the other hand, in more advanced cases, the body creates new blood vessels when trying to give blood. However, these are abnormal and do not provide the correct blood flow.

In addition, the disease can be obtained in type 1 or type 2 diabetes. Type 1 is caused by the immune system problem, while type 2 develops at any time of the patient's life and its appearance is related to eating habits and lifestyle.

What to do?

Palacios explained that the treatment of this disease is surgery. There are currently two procedures: laser photocoagulation (which destroys abnormal retinal structures) and vitrectomy (a technique that removes a glassy, ​​transparent gel that fills the eye cavity).

In addition, there are medications that prevent the formation of abnormal blood vessels, which are administered through intravitreal injections (within the eye). If patients timely examine and follow the standard guidelines for treatment, less than 5% of diabetics will develop severe vision loss.

The expert has recommended diabetic patients to have periodic control with endocrinoloses. He also said that it is important to have frequent exams, according to what the expert suggests. Finally, he proposes a balanced diet, exercise, and alcoholic beverage avoidance. (Andean)
