How does diabetes affect the eye?


High blood sugar levels due to a lack of insulin from diabetes can cause eye problems over time, such as making your small blood vessels and capillaries leaky. In the eye, this can mean blood and fluid entering the retina and damaging the cells which detect light.

In the long term, diabetes can lead to other eye problems including cataract, glaucoma and diabetic retinopathy.
