ologists had to deal with. Fortunately, in recent years, a number of large national studies have proven that laser treatment of the retina can help control proliferative diabetic retinopathy and significantly prolong useful vision.
Ironically, laser treatment works by producing scarring on the affected retina. The treated part of the retina will no longer see, but the laser treatment halts the growth of new blood vessels and preserves vision in the most important part of the retina, the macula. Laser treatment for diabetic retinopathy is a tremendous tool that has expanded the ability to treat diabetic eye problems.
A surgical procedure called a vitrectomy, in which blood, scar tissue, and vitreous are removed from the eye and replaced with a saline solution, is also a relatively new, successful treatment for retinopathy that affects the vitreous.
Looking out for your eyes
Currently, the American Diabetes Association recommends that adults and children 10 and older with Type 1 diabetes have an initial dilated and comprehensive eye examination within five years after they are diagnosed with diabetes. People with Type 2 diabetes are advised to have a dilated and comprehensive exam shortly after the diagnosis of diabetes. After the initial exam, everyone with diabetes is encouraged to have a yearly exam.
In a study published in the March 2001 issue of Diabetes Care, however, researchers studying retinal photographs taken during the Diabetes Control and Complications Trial discovered that in people with Type 1 diabetes, the progression of diabetic retinopathy begins even earlier than had previously been thought. Waiting up to five years to have an initial eye exam is too long, they suggested, because it may already be too late for the best treatment. They concluded that all individuals newly diagnosed with Type 1 diabetes should have an eye exam upon diagnosis.
With recent improvements in treatments, the chances of avoiding vision loss from diabetes- and age-related eye conditions are greater than ever, but vigilance is key. If you have never had a dilated eye exam or haven’t had one within the past year, ask your doctor for a referral to an eye-care professional who is trained to diagnose diabetic retinopathy. Take this important step now, and follow up with yearly visits.
