If total vision loss/ blindness has occurred, nothing can be done to reverse or treat the visual loss
caused by diabetic retinopathy. But if the disease is diagnosed in due time; during the early stage,
several treatment modalities could be considered.
The first thing that to do would be to control the blood sugar levels, blood pressure and blood
cholesterol levels. Blood sugar, hypertension, and cholesterol levels can be controlled by
adhering to the diet modification and exercise regimen recommended by your doctor or
nutritionist. Controlling these parameters can cause some of the visual functions to return
Anti-vascular endothelial growth factor (anti-VEGF) and steroids are medications that help to
reduce swelling in the retina, thereby improving vision. They are usually injected directly into
the affected eye.
Surgical procedures that are used to treat diabetic retinopathy include laser surgery and
vitrectomy. Laser surgery is used to repair damaged blood vessels and to shrink new blood
vessels that grew as a result of the disease. Shrinking and repairing of these vessels reduces
retinal swelling and improves vision. Vitrectomy is a procedure that helps to drain blood, fluid,
and gel from the eyes. Drainage of these substances allows light rays to focus correctly on the
retina, therefore improving vision.
