Diabetic retinopathy is an age-related eye disease that can manifest itself with blurred vision, gray or black spots moving with the eye, and blurred vision. This was told to socialbites.ca by the head of the ophthalmology department of the Russian Scientific Surgical Center named after G. Akad. B. V. Petrovsky, candidate of medical sciences Shakhlo Makhkamova.
“Like other diseases, it does not manifest itself in any way in the initial stages. The first symptoms appear at a late stage of the disease. When the swelling affects the center of the retina, the patient experiences blurred vision, it becomes difficult to read, write, type at close range and work with small details. In hemorrhages, floating gray or black dense spots appear that move in the eye, giving the feeling of a veil or cobweb in front of the eyes. These symptoms occur due to damage to the blood vessels in the fundus. After treatment, the spots disappear when the hemorrhages are resolved. However, the symptoms may reappear if the glucose levels are unstable or blood pressure increases,” the doctor said.
This eye disease develops in type 1 and type 2 diabetes. The patient experiences changes in the blood vessels of the fundus of the eye, and sometimes people even learn from an ophthalmologist what diabetes is.
“Hyperglycemia and glucose toxicity eventually lead to the death of cells in the blood vessels, pericytes, which control fluid exchange by constricting and dilating the capillaries. After the damage, the permeability of the retinal blood vessels increases, the retinal layers become thin and stretched due to the pressure of the fluid accumulated under them. This leads to the formation of microaneurysms, small local dilations of the retinal capillaries that contribute to the development of ischemia. In advanced cases, the person loses his vision,” the ophthalmologist explained.
With type 2 diabetes, this disease becomes more serious. First, people often do not realize that they have diabetes, and eye damage occurs approximately 10-15 years after the onset of the disease due to incompletely treated diabetes. Therefore, the elderly are faced with diabetic retinopathy.
What other eye diseases can begin after the age of 40, what symptoms indicate them and why will the number of patients suffering from eye pathologies increase in the future? report Makhkamova “socialbites.ca”.
