Diabetes and your Eyes

Did you know that an eye exam can be the first clue to identifying diabetes and other hidden health concerns? Finding these issues early can give patients a better chance at preventing damage through early treatment and management.

What is diabetes?

Diabetes is defined as a group of diseases characterised by high blood glucose levels that result from defects in the body's ability to produce and/or use insulin.

One of the well-known effects of diabetes is eye and vision damage caused by diabetic retinopathy. This means that delicate blood vessels in the eye swell or bleed. They may also grow abnormally on the retina itself. This allows unprocessed blood sugars, fats, and proteins to leak out of weakened blood vessels. That's what damages the retina and can cause vision loss.
