Diabetes and Your Eyes
Diabetes can harm your eyes. It can damage the small blood vessels in your retina, which is the back part of your eye. This condition is called diabetic retinopathy. Diabetes also increases your risk of having glaucoma, cataracts, and other eye problems.
Diabetes is a chronic disease in which the body cannot regulate the amount of sugar in the blood.
You may not know there is any damage to your eyes until the problem is very bad. Your health care provider can catch problems early if you get regular eye exams.
If your provider finds eye problems early, medicines and other treatments may help prevent them from getting worse.
You Need Regular eye Exams
Every year, you should have an eye exam by an eye doctor (ophthalmologist). Choose an eye doctor who takes care of people with diabetes.

Your eye exam may include:
- Dilating your eyes to allow a good view of the entire retina. Only an eye doctor can do this exam.
- At times, special photographs of your retina may replace the dilated eye exam. This is called digital retinal photography.
Your eye doctor may ask you to come more or less often than once a year.

Make it Easier for Yourself at Home
If your vision is affected by diabetes, make sure your home is safe enough that your chance of falling is low . Ask your doctor about having a home assessment done. For people with diabetes, the combination of poor vision and nerve problems in the legs and feet can affect balance. This increases the chance of falling.

If you cannot read the labels on your medicines easily:

- Always read labels with a magnifying lens.
- Use a pillbox with compartments for days of the week and times of the day, if you need to take medicines more than once a day.
