Diabetes-Related Eye Diseases

1. Diabetic Retinopathy

Diabetic retinopathy happens when the blood vessels in the eyes are damaged due to high blood pressure. The blood vessels will bleed and blood and fluid will flow into the retina.

The leakage can cause permanent vision loss and irreversible damage to the retina.

Symptoms
Blurry vision
Loss of colors
Loss of central vision
Holes or black spots in vision

Natural prevention
Eat fruits that are great sources of vitamins A and C which will strengthen the blood vessels in the eyes. So will honey. Gingko biloba is good for increasing the diameter of the blood vessels to improve blood circulation.

Quercetin, an antioxidant, and anti-inflammatory, may help people with blood vessel-related disorders are found in citrus frutis, leafy green vegetables, tomatoes, apples, dark cherries, etc.


2. Diabetic Macular Edema (DME)

Because of Diabetic Retinopathy, blood and fluid will flow into the retina. This affects the retina directly and cause vision loss.

Symptoms
Images directly in front of you appear blurry or wavy
Colors appear dull

Natural Prevention
If you prevent diabetic retinopathy, you will prevent DME. Be sure to always monitor your blood sugar levels and see your eye doctor at least once a year.


3. Glaucoma and Cataracts


Cataracts are more often associated with those who have type-2 diabetes. A cataract is the clouding of the eye’s lens due to a protein build up. It causes blurred central vision and fortunately, the loss of vision is reversible.

Just as a ball requires air pressure to maintain its shape, the eyeball needs internal fluid pressure to retain its globe-like shape and ability to see. When the pressure starts building up, it cannot be released. It will just keep building and pushes the optic nerve until the damaged is permanent and vision is lost.

Glaucoma is the leading cause of blindness in many countries.

Natural Prevention
Some causes of cataracts include ultraviolet radiation from sun and other lights, high myopia, eye injury or inflammation, previous eye surgery. So take care of your eyes from injuries and environment.

Another way to prevent glaucoma is by doing regular moderate exercise. Cardiovascular exercises such as aerobics will lower intraocular pressure, which is pressure in your eyes, and that helps to keep the retinal ganglion cells protected. Cardio exercise also increases the flow of blood to the optic nerve and the retina.

See your eye doctor at least once a year.
