Diabetes and Your Eyes

Diabetes and Your EyesDiabetes affects your entire body, including your eyes. According to The American Academy of Ophthalmology, diabetics are 25 times more likely to lose vision than those without this disease. The most common complication of diabetes is diabetic retinopathy, and the longer you have diabetes, the more likely it is that you’ll develop diabetic retinopathy.
High blood sugar levels, as associated with diabetes, often affect blood vessels in the retina of the eye, causing diabetic retinopathy. There are 2 stages of classifications of diabetic retinopathy: non-proliferative or proliferative.
Non-proliferative retinopathy, sometimes known as background diabetic retinopathy, is the most common form of the disease. This condition is first diagnosed when small retinal blood vessels start to swell. As the disease progresses, these blood vessels break and leak blood.
Proliferative retinopathy is the more advanced stage of diabetic retinopathy. As the condition progresses, more and more blood vessels are blocked. Sensing the need for new blood vessels to supply nourishment, new blood vessels grow, but they are frail and abnormal, often hemorrhaging and scarring. Patients with this type of diabetic retinopathy can experience severe vision loss, and even blindness.
At both the early and advanced stage, fluid can leak into the macula, the center of the retina that allows you to see fine detail. Known as macula edema, it is another common cause of vision loss in diabetics.
It is worth noting that smoking does accelerate the damaging effect that diabetes has on the retina. Several other influencing factors include your genes, your blood pressure levels, how long you have had diabetes and of course, your blood sugar level.
In the early and most treatable stages of diabetic retinopathy, there are usually no visual symptoms or pain. In fact, many times the disease can even progress to an advanced stage without your noticing the gradual change in your vision.
Symptoms of Diabetic Retinopathy
May Include:
. Abnormal patterns in the field of vision
. Dark streaks in your vision
. Sudden onset of decreased vision
. Distorted central vision
. Floaters
. Red film that blocks vision
. Blind spots
. Poor night vision
. Items may have a blue-yellow color tone, interfering with color perception
We strongly recommend that all diabetics have yearly comprehensive medical eye exams. Your eye doctor will dilate your eyes and check your retina, blood vessels and optic nerves for changes. We may also order a fluorescein angiography to track and photograph dye as it flows through the retina to look for leaking blood vessels.
We also commonly perform an Optical Coherence Tomography (OCT) to assess fluid accumulation (macular edema) in the retina of diabetics.
The OCT can show areas of retinal thickening and is often a useful tool in assessing a patient’s response to a treatment.
Treatment
The most important tool for treating diabetic retinopathy is good management of the underlying diabetic condition. Nevertheless, once diabetic retinopathy has presented itself, there are several methods of treatment. Lasers are the mainstay; often used to treat the early stages of diabetic retinopathy by sealing leaking blood vessels. More advanced cases may require a vitrectomy, a surgical procedure needed when the vitreous, the gel in the eye, contains a great amount of blood.
The optimal time for treatment is before the patient experiences visual symptoms so early detection and treatment is the best protection against significant vision loss. Diabetic retinopathy can progress into its advanced stages with no pain, no recognizable vision loss. That’s the reason it is so important for all diabetics to get a yearly comprehensive medical eye examination.
Please take time to educate yourself, and any loved ones with diabetes, on how to preserve their vision.
