Understanding Glaucoma

According to the Canadian Association of Optometrists, Glaucoma is one of the leading causes of blindness in Canada. Called the “Silent Thief of Sight”, glaucoma is actually the name given to a group of diseases that cause progressive damage to the optic nerve, eventually leading to vision loss and even blindness. Since January is Glaucoma Awareness Month, this would be an ideal time to study the causes and prevention of this condition.

What Do We Know About Glaucoma?

As of yet, we still don’t know the precise cause of glaucoma. For the most part, glaucoma is associated with high fluid pressure in the eye, but there are some exceptions to that rule.

The Connection Between Vision and Diabetes

November 14th is World Diabetes Day, a day dedicated to global recognition of diabetes and how it affects everyone. It is a safe bet that virtually everyone in Canada has heard of, and likely knows someone who is living with diabetes. Currently, there are nearly 11 million people living with either diabetes or prediabetes, a disease that causes the body to either fail to produce insulin, or makes it incapable of using it. Since insulin helps the body control blood sugar, people with diabetes suffer from high blood sugar levels. You may be aware that high blood sugar can damage your body’s organs, but were you aware that your eyes were included in the potential damage?

Unfortunately, this is a very real possibility.
