Effect of Diabetes on Eye sight

Diabetes can significantly affect eyesight by damaging the blood vessels in the retina, leading to a condition called diabetic retinopathy, 

which causes blurred vision and even vision loss if left untreated; 

Key points about how diabetes affects eyesight:

Diabetic retinopathy:

This is the primary eye complication of diabetes, where high blood sugar damages the tiny blood vessels in the retina, causing them to leak 

fluid and potentially leading to vision loss. 

Macular edema:

Swelling of the macula, the central part of the retina responsible for sharp vision, is a common complication of diabetic retinopathy and can cause blurred or distorted vision. 

Cataracts:

People with diabetes are more likely to develop cataracts, a clouding of the eye lens, at a younger age than those without diabetes. 

Glaucoma:

Diabetes can increase the risk of developing glaucoma, a condition that damages the optic nerve and can lead to vision loss if not treated. 

Blurred vision:

Fluctuations in blood sugar levels can cause temporary blurred vision due to changes in fluid within the eye.
