Diabetic Retinopathy: Causes, Symptoms and Treatment

Dr. Rodger Bodoia, M.D., Ph.D., specialist in diabetic eye care, explains the nature of proliferative diabetic retinopathy and how it is cared for.
A complication of diabetes is called diabetic retinopathy.. It is manifested by vascular affection of the retina, which often leads to blindness. For patients suffering from diabetes, this complication occurs in 80-90 % of cases. Among them  complete blindness occurs among 5% of patients. The others have various violations of visual acuity.

Diabetic Retinopathy: Causes, Symptoms and Treatment

Diabetic retinopathy: Causes

The only cause of diabetic retinopathy is the long duration of the diabetes. Vascular wall deteriorates with the passage of blood with high concentration of glucose through the vessels. Thus, the lumen of the vessel narrows and vascular wall becomes thickened. Given the fact that the retina contains a large number of arteries, capillaries, veins, blood vessels of the retina are affected ten years after the disease of diabetes occurred.

Initially, the vessel volume is reduced, causing the blood flow acceleration that leads to further collapses of vessel choroid. As a result, tiny capillaries in the retina become clogged gradually and their permeability increases. Because of these changes the connection between veins and arteries is formed that is aimed to compensate blood flow. This process further exacerbates the situation, as there are new vessels, aneurysms, and hemorrhage. These phenomena lead to detachment and irreversible changes in the retina and blindness.

Diabetic retinopathy: Symptoms

The first signs of diabetic retinopathy is a periodic discomfort experienced in the eyes and blurred vision. Patients almost never pay attention to these disorders, explaining them by all other causes: heredity, age, work at the computer and so on.

If you are infected with retinal hemorrhages, n the first sight there appear blurry or black spots, fuzzy visibility of objects. This symptom is not of a permanent nature. With resorption of blood clots stains disappear and the patient believes that his health condition was normalized.

With the simultaneous rupture of several vessels and active bleeding, as a result, there occurs retinal detachment and blindness. If you do not receive timely treatment interventions that occur in the retina may have irreversible changes .

Diabetic retinopathy: treatment

Control blood sugar levels.

Use intravenously or intramuscularly angioprotectors.

Take vitamins of C, E , P , B group ( B1, B2 , B6, B12).

 Micro-operations (laser photocoagulation) .

With timely carrying out of treatment and preventive measures it is possible to save the eyesight for more than half of patients. After five years of being diagnosed with diabetes mellitus, patient should regularly come for a visit to an ophthalmologist for the early detection of retinopathy .
