The Correlation Between Diabetes And Eyesight

November is Diabetes Awareness Month. For the millions of us who are at risk for diabetes, it’s a time to get educated, find resources, and make sure all those around us are aware of their risk as well. Through advocacy, program development, and education the American Diabetes Organization “aims to improve the quality of life for the over 133 million Americans living with diabetes or prediabetes. New technologies to manage diabetes, better resources to educate ourselves, and a community that’s stronger than ever.”

Just as annual physicals are important to keep you in optimal health, annual eye exams may uncover undetected disease.  Did you know diabetes also can harm your eyesight? Obtaining regular screenings will allow you to monitor your health and react to any changes that may have occurred.

The American Academy of Ophthalmology (and the American Diabetes Association) recommend patients with type 1 diabetes receive an eye exam within the first 5 years after diagnosis, then one exam per year. The groups recommend those with type 2 diabetes receive an eye exam as soon as diabetes is diagnosed, and then once yearly.

All people with diabetes are at risk of developing eye disease that can permanently damage their vision and can lead to blindness.

However, some steps can be taken to help prevent diabetic eye disease, including:

  • Managing good blood sugar, blood pressure, and cholesterol control
  • Scheduling a yearly comprehensive dilated eye exam
  • Women with diabetes before pregnancy should have a comprehensive dilated eye exam early in their pregnancy. Additional exams may be recommended during pregnancy.
  • Maintaining a healthy lifestyle by exercising regularly, not smoking and following a healthy diet

While everyone needs to schedule routine eye exams, people with diabetes need to be especially vigilant in scheduling their annual exams. Diseases such as glaucoma, cataracts, and retinopathy are best treated when they are detected early and are often associated with diabetes. Talk to your eye doctor about any concerns or vision loss you may be experiencing for the best chances of early detection and treatment.

Patients often ask, “Why do I have to have my eyes dilated?” This type of exam allows doctors to check the retina for various types of disease.

Early Warning Signs Of Diabetic Eye Disease

  • Warning signs of leaky blood vessels, such as fatty deposits
  • Changes to blood vessels
  • Changes in the lens
  • Swelling of the macula
  • Damage to nerve tissue

Glaucoma occurs when pressure builds inside the eye and is 40% more likely to occur in individuals who have diabetes. The pressure pinches blood vessels that carry blood to the retina and optic nerve. Vision is gradually lost as the retina and nerves are damaged from the increase in pressure. There are several treatments available for Glaucoma however some treatments may require surgery. Early detection of high pressure may be able to be managed by medication. Maintaining the proper eye pressure is key to preventing permanent damage to the eye.

As we age many people run a higher risk of developing cataracts. Those with diabetes are 60% more likely to develop them. By detecting cataracts early you can help to slow down the progression. The typical corrective action for cataracts is to remove the lens of the eye. Patients then would typically receive a new transplanted lens. In people with diabetes, vision can get worse after the removal of the lens and glaucoma may start to develop so additional treatment may be necessary.

Retinopathy is a general term used for all disorders of the retina that are caused by diabetes. The good news is that there have been giant strides in the past decade on treatment for retinopathy.

Have you noticed a pattern? Particularly those with diabetes must be extra vigilant with screenings and health checkups. The key to being able to keep your vision as clear as possible when you suffer from diabetes is early detection. Keep in mind that you often can lose more than 60% of your vision before you begin to notice significant differences. Talk with your doctor if you have diabetes so you know what symptoms to look for and schedule your annual vision screening.
