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.

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.

A comprehensive eye examination is the only reliable means of detecting diabetic retinopathy. After the pupil is dilated, a device called an ophthalmoscope is used to view the retina and determine the extent of the retinopathy. If diabetic retinopathy is discovered optical coherence tomogram (OCT) may be recommended.

Retinal Changes Seen in Diabetic Retinopathy

If diabetic retinopathy becomes uncontrolled new blood vessels can grow and block the natural drainage of the eye. This leads to neovascular glaucoma and often requires aggressive treatment to save the vision. This treatment is coordinated with a retinal specialist to ensure the best possible long term outcomes for patient.

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. If diabetic retinopathy progresses or becomes uncontrolled often a retina specialists is consulted for treatment options. Laser surgery is often the first line of treatment if macular edema or proliferative retinopathy is present. For macular edema, the laser is focused on leaky areas of the retina to aid in reabsorbing the excess fluid. The primary goal of this treatment is to prevent further vision loss. It is uncommon for people to recover significant vision following treatment but some do experience partial restoration. Laser surgery is not a cure for diabetic retinopathy and is not guaranteed to prevent further loss of vision. Other treatments for diabetic retinopathy include medications like steroids or a novel class of medication called anti-VEGF.
