What is Diabetic Retinopathy?

Description of the disease:

Diabetic retinopathy is a complication of diabetes that affects the eyes and can lead to vision loss. The disease develops due to damage to the blood vessels of the retina, caused by high levels of sugar in the blood.


  • Early diabetic retinopathy
  • Late diabetic retinopathy (including retinal edema, proliferative retinopathy, and neuropathy)


Symptoms may include blurred vision, floating black spots or patches, changes in color perception, difficulty seeing in low light, and loss of peripheral vision.


The cause of diabetic retinopathy is damage to the blood vessels of the retina due to prolonged high levels of sugar in the blood.


Diagnostics include examination of the fundus of the eye, determination of visual acuity, measurement of intraocular pressure, and other methods.


Treatment may include laser therapy, injections of drugs into the eye, and surgical intervention.


Prevention includes maintaining a stable level of blood sugar, regular examination by an ophthalmologist, and control of blood pressure and cholesterol.


The diagnosis and treatment of diabetic retinopathy is carried out by an ophthalmologist.
