How can diabetes affect your eyes?

 

Cataract

People with diabetes are 2 to 5 times more likely to get this condition - a clouding or fogging of the normally clear lens of the eye - than those without diabetes. Cataract, which is a leading cause of blindness in American adults, also tends to develop at an earlier age in people with diabetes.

Glaucoma

Glaucoma may occur amongst people with and without diabetes, however, diabetes nearly doubles the risk of this eye condition. Glaucoma is a group of diseases that damage the eye’s optic nerve, causing changes in vision.

Diabetic macular edema (DME)

Diabetic macular edema (DME) is a condition that makes your retina to swell due to leaking of fluid from blood vessels within the macula. DME is a consequence of diabetic retinopathy and can cause blurry, washed-out vision.

Diabetic retinopathy

High blood sugar levels from diabetes can damage the tiny blood vessels on the retina, leading to diabetic retinopathy. It is the most common cause of vision loss among people with diabetes as well as the leading cause of vision impairment and blindness among working-age adults.

Initially, diabetic retinopathy may cause no symptoms or only mild vision problems. Symptoms, if develop, may include:

• Blurry or double vision
• Rings, flashing lights, or blank spots
• Dark or floating spots
• Pain or pressure in one or both of your eyes
• Trouble seeing things out of the corners of your eyes

All people with diabetes mellitus - those with Type I diabetes and those with Type 2 diabetes- are at risk of diabetic retinopathy.
Therefore, people with diabetes should make regular visits to their ophthalmologists for eye exams to avoid eye problems besides controlling blood sugar and high blood pressure. Remember, treating problems early can save your vision.
