You may already know that diabetes increases your risk of developing vision problems. High blood sugar can damage the tiny blood vessels in your eyes and cause complications like diabetic retinopathy and diabetic macular edema.
But what you may not realize is that people with diabetes almost always have unique eye care needs and considerations, even if their blood sugar is well controlled. Here are some of the common impacts of diabetes on your eye health and ways that your eye care may be adapted.
People with diabetes are twice as likely to develop cataracts than other adults — and cataracts are more likely to show up at a younger age. Cataracts cause your natural lens to become cloudy, leading to blurry, hazy or less colorful vision. Over time, you may need surgery to restore your sight.
With diabetes, you have a higher risk of swelling in the retina, also known as macular edema, after cataract surgery. This is especially true if you have diabetic retinopathy. Either way, your ophthalmologist may want you to be checked by a retinal specialist prior to cataract surgery and receive pre-treatment if necessary. Therapies may include steroid or anti-VEGF injections aimed to control inflammation in the retina.
Having diabetes doubles your odds of developing glaucoma, a chronic condition where retained fluid causes pressure to build up inside the eye. Extra pressure can damage the retina and the optic nerve, harming your vision.
Sometimes, treatments for diabetes-related eye conditions can also elevate eye pressure. For example, steroid treatments to reduce swelling in the retina can cause spikes in eye pressure. If you are being treated by a retinal specialist, they may also refer you to a glaucoma specialist for ongoing maintenance and monitoring.
If you do have glaucoma, you will also have a higher risk of elevated eye pressure after cataract surgery.
Diabetes does not affect your risk of developing age-related macular degeneration (AMD). However, some of the symptoms and treatments for these two conditions may overlap.
For example, diabetes-related macular edema, diabetic retinopathy and AMD can all lead to leaky blood vessels in the retina. All three of these conditions may be improved by treatment with anti-VEGF injections.
If you have diabetes, it's important to watch for early signs of trouble in your eyes.
Treatments for diabetes-related eye problems are expanding and improving. The sooner you notice a symptom, the more likely treatment will help.
