Diabetic Eye Care

If you have been diagnosed with diabetes, you may be at risk of losing your vision since your body does not utilize sugar properly and, when the sugar levels rise, damage to the retinal blood vessels may occur. This injury to the retinal vessels is known as Diabetic Retinopathy. Diabetic Retinopathy is the leading cause of blindness in working-age adults.

What are the symptoms of diabetic retinopathy?

Often, one may not be aware of any symptoms even when significant diabetic retinopathy is present. When macular edema occurs, vision often becomes blurry and may fluctuate. If abnormal new blood vessels form, as in proliferative diabetic retinopathy, they may bleed and result in small specks or large floaters obscuring the vision. If a large hemorrhage occurs, vision often becomes very blurry.

How is diabetic retinopathy diagnosed?

A comprehensive eye examination by an optometrist or ophthalmologist is the only reliable means of detecting diabetic retinopathy. We use the state-of-the-art Optos digital retinal exam to to throughly view the retina and determine if retinopathy is present. If diabetic retinopathy is discovered, a fluorescein dye test and/or optical coherence tomogram (OCT) may be recommended. A fluorescein angiogram involves the injection of a dye into a vein in the arm followed by several minutes of intermittent photos with a special digital camera focused on the retina. An OCT is a non-invasive photo that creates a detailed cross-sectional image of the macula.

What is the treatment for diabetic retinopathy?

The best therapy for diabetic retinopathy is prevention. Studies show that strict control of blood sugar levels can significantly lower the risk of vision loss from diabetic retinopathy. High blood pressure and kidney problems should also be treated to minimize their effect on the retinopathy. Laser surgery, steroids and a novel class of medication called anti-VEGF treatments are available. The primary goals of these treatments is to prevent further vision loss. Most people don't fully recover to 20/20 vision following these treatments, but some do experience partial restoration. There is no cure for diabetic retinopathy and the treatments do not guarantee further loss of vision.
