There are many things that can cause eye strain and blurry vision, such as spending a lot of time in front of a screen. But blurry vision is also a common warning sign for diabetes. If not caught early or properly managed, diabetes can damage the small blood vessels in the retina — a layer of light-sensitive tissue at the back of the eye that sends visual signals to the brain. This condition, called retinopathy, can result in blindness.
Diabetes is a complex disease that occurs when your body does not produce insulin normally. Insulin is a hormone that allows the body to break down sugars that our cells use for energy. Increased blood sugar (or blood glucose) can cause the lenses of your eyes to swell with fluid, causing distorted vision or blurriness. If not managed, unhealthy sugar levels can progress to diabetic retinopathy.
Preventing diabetic retinopathy
In order to prevent permanent damage to the retina, doctors recommend a yearly eye exam with dilation. Dilation involves using drops that open the pupil and allow doctors to examine the retina for damage. In addition to regular eye exams, these steps can lower the likelihood or severity of diabetic retinopathy:
Pay attention to warning signs
As diabetes progresses, blood vessels in the retina may be permanently damaged. The longer you’ve had diabetes, the higher your chance of developing some level of retinopathy, particularly if you haven’t taken preventive steps.
If you are diabetic, be aware that blurriness is just one symptom of retinopathy. Others include:
While some patients with retinopathy have symptoms, many do not. Without regular eye exams, retinopathy can quickly become problematic. This makes treatment less effective, or even impossible.
Treating diabetic eye problems
If you do have retinopathy, continue to follow prevention measures to slow the progression of the disease. With advanced disease, your doctor may recommend more aggressive treatment options to prevent blindness. These include:
