Understanding Glaucoma: the Silent Thief of Sight

Did you know that over 400,000 Canadians suffer from glaucoma? Every year, more and more people are diagnosed with this disease, many of them not even having noticed any symptoms. Glaucoma works quietly, leaving cumulative and irreversible damage in its wake.

At Shelburne Primary Eye Care, we’re ready to help you understand the dangers of glaucoma, as well as the treatments. We’ve invested heavily in top-of-the-line technology to help us thoroughly screen for early indicators of glaucoma. It’s our pleasure to answer all your questions and explore all your eye care options with you.

What is Glaucoma?

Part of your eye is filled with a fluid called the aqueous humour. This fluid is constantly refreshing itself; draining away as your body makes more. But sometimes, the fluid doesn’t drain properly, causing intraocular pressure (IOP) to build as your body continues to make more fluid. If the IOP level gets too high, it can damage the optic nerve, which is responsible taking information from the eyes to the brain. Once the optic nerve is damaged it cannot be repaired.

Glaucoma is sorted into different types or variation. Each variation is based on the reason behind the lack of proper drainage in the eye.

If the angle between the iris and the cornea is wide enough for fluid to pass through, but the drainage canals are clogged, it’s called open-angle glaucoma. This particular variation of the disease is the most common, making up about 90% of cases. It is slow but painless; building up over a lifetime.

In normal tension glaucoma, the drainage canals are clear, and the angle between the iris and the cornea is wide enough to facilitate flow. Despite these factors, vision loss occurs. Although medical science is always moving forward, as of now, doctors still don’t know what causes normal tension glaucoma.

In most cases, glaucoma does not present any symptoms. Angle-closure glaucoma is the exception to the rule. This version of the disease occurs very quickly causing violent symptoms including nausea, severe eye and head pain, blurry vision, and excessive tearing. These symptoms are caused by the angle between the iris and the cornea suddenly closing.

Annual Eye Exams are the Best Way to Detect Glaucoma

Because most cases of glaucoma develop without symptoms, people often carry on untreated for years before they finally notice their loss of vision. By having an eye exam every year, you’re giving us the chance to annually check your eyes for any early signs of glaucoma. Once we’ve diagnosed it, we can prescribe the right treatment to delay and limit the damage it could cause. Schedule your eye exam with us today.
