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.

Keeping an Eye on High Blood Pressure

Since World Diabetes Day was on November 14th, now may be a good time to discuss a condition that often goes hand in hand with Diabetes, and that is Hypertension, or High Blood Pressure. I’m sure that everyone has heard the warnings about high blood pressure increasing the risk of stroke, heart failure and kidney disease. But are you aware that high blood pressure can damage your eyes as well?

February is AMD and Low Vision Awareness Month

February has been dedicated to raising awareness of AMD and Low Vision in Canada. Age Related Macular Degeneration (AMD) is the leading cause of blindness in those over 50 and often comes on so slowly that people generally don’t notice it until their vision has been severely impaired.

What is Age Related Macular Degeneration?

The macula is a tiny piece at the back of the retina which controls your sharp central vision. This is the area affected by AMD, beginning by attacking your ability to see fine details. It may begin with having trouble reading fine print, or possibly a blur in your central vision. Eventually you will have trouble reading, driving, or doing an activity which requires the ability to see clearly. Left untreated, it will very likely cause total blindness.
