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?

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?

Heterochromia – An Eye of a Different Colour

We are used to people having different eye colours, brown, blue, green, hazel, etc. We may even have seen someone whose eye colour appears to change, depending on lighting. But have you ever met someone who has two distinct different eye colours? Have you ever wondered what may cause something like that to happen?

Arthritis and How it Affects Your Vision

September is Arthritis Awareness Month. Arthritis is a chronic disease that currently affects more than six million Canadians, or over 20% of the population over the age of 15. Nearly 24,000 children have arthritis, as do almost 50% of seniors over the age of 65. Arthritis is an inflammatory condition that can attack the joints in your fingers, toes, hands, arms, legs, the ligaments of your spinal column from neck to low back, hips and shoulders. But were you aware that it can also affect your eyes?

What Does it Meant to be Colour Blind?

Many of you have probably heard the term Colour Blind before. You may even know someone who is colour blind to a greater or lesser degree. But do you know what it means? Does it mean that you see the world in black and white? Well, not exactly. In fact, some people may be colour blind and not even aware of it.

Will my Child Inherit my Eye Problems?

We know that many things that make us who we are can be inherited from our parents, hair and eye colour, facial features, height, or the lack thereof. Even some personality traits can be attributed to genetics, an easy going manner, or conversely, stubbornness, a love for reading or for taking apart and rebuilding things, a love of the outdoors. Other less desirable things can also be hereditary, such as arthritis, heart conditions or high blood pressure. But what about vision related problems? Can they also be inherited? Well, in some cases yes, but not necessarily.

Nutrition and Your Eyes

March is National Nutrition Month, a very good time to discuss the effect of diet on your vision. The average rabbit can tell you about the importance of carrots for your eyesight, but what other foods can help?

Aging and Eye Disease

We all know that as we get older, our bodies wear down and need more maintenance and upkeep. The same is true for our eyes. Some common eye diseases that are related to getting older are: Cataracts, Diabetic Retinopathy, Dry Eye Syndrome, Glaucoma, and Macular Degeneration.  Many of these age related conditions can be avoided or controlled by maintaining a healthy lifestyle, not smoking, getting regular exercise, and eating healthy. But what is a good diet to maintain eye health?
