Diabetes has become increasingly common over the last few decades, and the unfortunate part is that it brings with it several related medical issues.

Yes ladies, your eye health and blood sugar levels are linked.

Vision-related complications are frequent in people with diabetes.  Around 25% of people with type-1 and type-2 diabetes develop eye complications associated with high blood glucose levels. Uncontrolled blood glucose levels can damage the blood vessels supplying to the light-sensitive tissue present on the back of the eyes in the retina, thereby making it crucial for people having diabetes to control their blood glucose levels. 

Understanding the diabetic eye

The diabetic eye is a collective term given to a group of eye conditions that usually affect people having high blood glucose levels for a long time. Usually, people having diabetes develop diabetic retinopathy. The other conditions that develop due to the complications of diabetic retinopathy are diabetic macular edema, cataracts, and glaucoma. Diabetic macular edema and diabetic retinopathy are leading causes of blindness in people with diabetes.

Generally, people whose eyes develop diabetes-related complications may experience mild symptoms. However, some do not exhibit any signs. But the absence of symptoms does not mean that they cannot develop any complications associated with the diabetic eye.

People having diabetic eye may experience the following symptoms:

  • Blurring of vision
