Why Does Diabetes Cause Eye Disease

Whenever you eat, your body creates insulin to break down the glucose from your food and distribute it to different cells. Diabetes is a condition that occurs when someone isnt producing enough insulin or their body doesnt use insulin as well as it should. This leads to a build-up of glucose in the blood, and if not properly monitored, this excess can cause numerous health problems.

High levels of glucose in the blood can change the amount of fluid in your eyes or cause some of the tissue in your eyes to swell, causing blurry vision. If you lower your glucose levels in a short amount of time, your eyesight will return to normal, and there may be no permanent damage. However, having high levels of glucose for an extended period of time can damage your eyes permanently. This can cause diseases such as diabetic retinopathy, macular edema, and glaucoma. The increased levels of glucose in your blood might also damage the blood vessels in your eye, causing them to leak fluid or swell. Additionally, your body might begin to produce weaker blood vessels, which are more likely to leak fluid into the center of your eye. If enough leaked fluid builds up in the eye, it can create intense pressure and swelling, which can result in scarring and permanent damage.

Eye drops, oral medication, injections of medication, and surgery are all treatment options for the type of glaucoma that is associated with diabetes.

How Does The Eye Work

How does Diabetes affect your eyes?

To understand the eye disorders that can be caused by diabetes, its good to know how the eye works. The eye is covered by a strong outer membrane which is clear and curved. The curved part is the cornea which focuses light and helps protect the eye.

Once light passes through the cornea, it travels through the fluid-filled anterior chamber through the pupil and then through the lens that helps with focusing. The light then passes through another fluid-filled chamber in the middle of the eyeball and hits the retina in the back of the eye.


The retina records the light images that get focused on it and converts those images to electrical signals. The electrical signals are sent to the brain via the optic nerve and the brain decodes them. The macula, part of the retina, is highly specialized for seeing detail. Blood vessels in and behind the eye supply the macula with nourishment.
