Diabetic Eye Diseases

Diabetic Eye Diagram

Diabetes damages the nerves and blood vessels throughout a person's body, especially if their condition isn't managed properly. Having diabetes also increases a person's risk of certain eye conditions like glaucoma and cataracts. Because eye problems in diabetics are so prevalent, we give diabetics a solution for diabetic eye diseases.

Diabetic Eye Diseases

Diabetic Retinopathy

Diabetic retinopathy is one of the more common conditions that affect diabetes. It's actually the leading cause of blindness in adults in the U.S. This particular condition causes damage to the retina, which is the portion of the eye consisting of nerves. It's the part of the eye that receives light and transfers images to the brain. Two main types of diabetic retinopathy exist: non-proliferative retinopathy and proliferative retinopathy. With non-proliferative retinopathy, the small vessels in the back of the eye begins to swell. They then become leaky and bleed. On the other hand, proliferative retinopathy causes new blood vessels to grow, which prevents the retina from getting enough blood. The new vessels are weak, and it's possible for blood to leak from them. This condition causes floaters, blurred vision, black spots in your field of vision, and a loss of your central vision.


According to The Diabetes Council, diabetics are twice as likely to develop glaucoma than someone who doesn't have diabetes. The relationship between the two issues, however, isn't fully understood. This particular eye issue arises as a result of damage to the optic nerve. This region of your eye is responsible for sending messages from your eye to your brain. In most cases, the damage occurs due to high pressure in the eye. In many times, glaucoma doesn't have any symptoms in the early stages, making it imperative to get routine eye examinations for it. This is especially the case since any vision loss from glaucoma can't be recovered. Once the eye disease does cause symptoms, you may notice you have patchy blind spots. Generally, the spots occur in either your peripheral or central vision. Tunnel vision happens in more advanced stages. These symptoms are part of open-angle glaucoma. 


The connection between diabetes and cataracts isn't fully understood. It appears individuals with diabetes are 60-percent more likely to develop cataracts than someone without diabetes. Cataracts cause a clouding on the lens of your eye. People with cataracts may feel like their looking through a fogged window. Although cataracts may develop slowly and not interfere with your vision at first, once they progress they cause clouded, blurred, or dim vision. It makes it difficult for someone to see at night. You may have a sensitivity to light or see halos around light. You might have a fading or yellowing of colors.

Importance of Routine Screening

While it's important for all individuals to receive routine eye screenings, it's even more so for diabetic patients. Once glaucoma progress, the conditions are manageable but not reversible. Once cataracts worsen too much, surgery is the only way to correct the problem. With management techniques, you may keep your eyesight for longer since either condition may lead to blindness.

Treatment for Eye Problems

The treatment depends upon the condition. For instance, you may receive a prescription for eye drops or an oral medication to reduce the pressure in your eye if you have glaucoma. Patients with cataracts may need frequent changes in their eyewear prescription to combat the problem. Surgery may be necessary for the advanced stages of either cataracts or glaucoma. For diabetic retinopathy, laser surgery may be necessary to remove vessels or treat abnormal ones.
