Diabetes and Blindness

Diabetes and Blindness

Diabetes can cause an array of complications. One of them is eye problems. This varies from blurry vision to even blindness. People with diabetes have a higher chance of becoming blind than those who do not have diabetes.

How diabetes can cause blindness

People with diabetes have high blood glucose levels. This could lead to eye damage. At an early stage, the symptoms aren’t very obvious. Over time, the symptoms could include blurry or double vision, seeing floating spots, rings or flashing eyes and pain or pressure in the eyes. There are two mayor eye complications that could lead to blindness: glaucoma and retinopathy.


People with diabetes have a higher chance of suffering from glaucoma than people without diabetes. Glaucoma develops when there is a high amount of pressure in the eye. The pressure (intraocular) damages the optic nerve and could eventually lead to permanent blindness.


Diabetic retinopathy takes place as a result of high blood glucose levels in the retina, the layer of cells at the back of the eye. The high levels of glucose damage the tiny blood vessels in the retina. If the tiny blood vessels are damaged, the retina won’t get the blood supply it needs to function properly. This can gradually lead to blindness.

Preventing eye problems

It is important to ensure that regular check-ups at the doctor become part of your schedule. Should you develop a problem with your eyes, then it is important you get the necessary treatment so that the condition does not worsen. Controlling blood glucose levels are also very important in preventing any complications of diabetes, not only eye problems.
