A Comprehensive Study on Cataracts and Diabetes

Amen Singh

Many people are still not aware of the fact that people who have diabetes are more at risk of developing vision stealing cataracts than the people who do not have the disease. The risk percentage is greater in the case of women sufferers. Even a simple eye examination can point fingers towards diabetes and other underlying health issues. Well, whatever the issue is, early detection provides patients a better chance of fighting with the disease.

If you are a diabetic then you must follow your doc’s instruction about your diet and maintaining blood sugar level. Cataract is a health condition in which a patient’s naturally clear lens becomes opaque resulting in a blurry vision. Generally, cataract is an age related disease, as you age it starts showing its symptoms. Other factors behind this condition include surgery, medication, prolonged exposure to sun and some diseases. Diabetes is probably the worst disease that develops cataracts even in young adults.

So how diabetes invites cataract?

The glucose level in the body is the catalyst of the disease. The lens of your eyes receives its nutrients from aqueous humor, a fluid filling that covers the front portion of the eyes. It is the source of oxygen and glucose for the body cells. If your body sugar level increases beyond normal limits then the sugar levels in aqueous humor and lens also increase. A higher percentage of glucose in lens makes it swell, affecting the clarity of the vision. The lens contains an enzyme that turns glucose into a substance called sorbitol. When sorbitol gets accumulated in lens it starts affecting cells and natural proteins making the lens blurry. This eventually leads to cataract formation in eyes making your vision weak, yellowish and faded.

Facts about diabetes and pre diabetes
