Diabetic Eye Care

Diabetes can damage the retina, which leads to diabetic retinopathy – a significant ocular disease that can diminish or destroy vision.

Diabetes is a systemic disease in which abnormal levels of sugar (glucose) build up in the bloodstream. The excess glucose causes changes that ultimately damage the walls of small arteries throughout the body. In turn, the reduced vessel function compromises many of the body’s systems.

What is diabetic retinopathy?

Diabetic retinopathy occurs when the retina’s blood vessels swell, leak, or close off, which can cause abnormal new blood vessels to develop on the retina. Early-stage diabetic retinopathy can be mild and may require no treatment. In advanced stages, however, it can lead to bleeding in the eye, retinal tears or detachments, and blindness.

Stealthy damage

When affected vessels are situated inside the macula (the central part of the retina responsible for seeing in fine detail), the patient will notice their vision blurring. When affected vessels are situated outside the macula, however, the patient may not notice anything - but significant damage is already underway.

Treating diabetic retinopathy


Treatments for diabetic retinopathy vary widely depending on the severity of the disease and the location of the affected areas.

Treatments include:

  • Argon laser photocoagulation
  • Intraocular injections
  • Surgical intervention

Diabetic patients who don't have a diabetic retinopathy diagnosis can be seen by their eye specialist once a year. For diabetic patients who have been diagnosed with diabetic retinopathy, the frequency of visits will be determined after a comprehensive eye exam and consultation with the doctor.

If the retinal damage is extensive, Dr. Khodadadeh may refer you to a retinal subspecialist for further management.

Diabetes can also lead to other eye problems, such as cataracts and glaucoma.

Cataracts is the excess blood sugar associated with diabetes can also cause cataracts or clouding of the natural lens, requiring cataract surgery.

Glaucoma is a disease that damages the eyes’ optic nerve due to increased intra-ocular pressure. Having diabetes can substantially increase the odds of developing glaucoma.
