Diabetic Retinopathy

Diabetic retinopathy refers to damage to the retina of one’s eye that occurs with long-term diabetes. It is very important that patients with diabetes see their ophthalmologist at least annually even if you believe your vision is fine. Many patients with diabetes have early changes in their eyes that, left untreated, will cause irreversible loss of vision. At Stahl Eyecare Experts, we very much believe that an ounce of prevention is worth a pound of cure. If we detect these early changes, many times we can prevent the loss of vision that otherwise would ensue.

Diabetic retinopathy is the leading cause of blindness in working-age Americans. People with type 1 diabetes and type 2 diabetes are at risk for this condition.

Having more severe diabetes for a longer period of time increases the chance of getting retinopathy. Retinopathy is also more likely to occur earlier and be more severe if your diabetes has been poorly controlled. Almost everyone who has had diabetes for more than 20 years will show signs of diabetic retinopathy.

Symptoms

Most often, diabetic retinopathy has no symptoms until the damage to your eyes is severe.

The eye specialist can diagnose diabetic retinopathy by dilating your pupils with eye drops and then carefully examining the retina. A retinal photography , fluorescein angiography, or ocular coherence tomography test may also be used.

If you have nonproliferative diabetic retinopathy, your eyes may reveal:

If you have proliferative retinopathy, your eyes may exhibit:
