Diabetic Retinopathy

Diabetes is a condition where the body does not produce enough insulin to convert sugar to energy, leading to a buildup of sugar in the blood


This leads to a number of problems, including diabetic retinopathy, which is one of the leading causes of adult blindness in Singapore.

What is Diabetic Retinopathy?

Diabetic retinopathy is a disorder of the blood vessels in the retina of patients with diabetes mellitus. It is the leading cause of new blindness in working adults in developed countries, including Singapore.

What Are the Main Causes of Diabetic Retinopathy?

Diabetic retinopathy first manifests itself slowly over the years as background retinopathy, which is the early stage of diabetic retinopathy. At this early stage, tiny blood spots or fatty deposits appear on the retina.

Over time, proliferative retinopathy develops from background retinopathy and is responsible for most of the visual loss in diabetics. In this condition, new blood vessels grow on the surface of the retina and optic nerve. These immature blood vessels tend to rupture and bleed into the cavity of the eye.

Scar tissue can also form from the ruptured blood vessels and can contract and pull on the retina, causing retinal detachment and vision loss. In some cases, new vessels can grow on the iris and cause a form of glaucoma, which can lead to blindness.
