Chronically elevated levels of sugar in your blood causes inflammation and damage to blood vessels—including the tiny ones which supply blood to your retinas. When this happens, the retinal tissue can begin to break down and scar, leading to progressive vision loss.
Symptoms of Diabetic retinopathy
· Spots or strings in vision (floaters)
· Blurred vision
· Poor color vision
· Empty areas in vision
· Vision loss
Types of Diabetic Retinopathy
Early diabetic retinopathy, also called nonproliferative diabetic retinopathy (NPDR), is the most common form of this condition and occurs when new blood vessels do not grow in the retina.
Advanced diabetic retinopathy, or proliferative diabetic retinopathy, is more severe and occurs when damaged blood vessels close off and new, abnormal blood vessels grow in the retina. This form may lead to the retina detaching from the back of the eye or can damage the optic nerve which carries images from the eye to the brain and lead to glaucoma.
Diabetic Retinopathy Treatments
The key to treating diabetic retinopathy is to get it diagnosed early. Advanced diabetic retinopathy may require prompt surgical treatment. Early diabetic retinopathy, on the other hand, may not need to be treated immediately. It is best practice to work with an endocrinologist, a diabetes doctor, to improve diabetes management as good blood sugar control can slow the progression of diabetic retinopathy.
