Glaucoma in Winnipeg

Glaucoma occurs when pressure inside the eye damages the optic nerve and causes blind spots. It tends to be a genetic disease, and may appear more frequently in families with a history of glaucoma over several generations.

The 3 most common types of glaucoma are:

• Open-Angle Glaucoma: is the most common form of glaucoma. The drainage angle and iris remain open, but the trabecular meshwork remains blocked and exerts pressure on the eye, damaging the optic nerve over time. This form of glaucoma rarely produces symptoms until vision is at risk.
• Angle-Closure Glaucoma (or Closed-Angle): occurs when the iris bulges forward and blocks the drainage angle. Fluid cannot circulate or release, resulting in increased pressure buildup. This type of glaucoma happens quickly and is considered a medical emergency that demands immediate attention.
• Normal-Tension Glaucoma: is not linked to rising pressure and occurs when the optic nerve sustains damage. Normal-tension glaucoma can appear in people whose optic nerves are extra-sensitive or receive less blood flow due to partially-blocked arteries.

Diagnosis is the first and most critical step to preserving your vision. Although the risk of glaucoma increases with age, this condition can affect anyone at any time in their lives.

The pressure that causes open-angle glaucoma is painless, making the disease difficult to detect. However, the following warning signs can make it easier to identify:

• Increasing loss of peripheral vision (suddenly or gradually)—also known as tunnel vision
• Compensating for lack of peripheral vision by tilting the head to see from one eye or the other
• Halos appearing around lights
• Frequent and severe headaches
• Unexplained nausea
• Blurred vision
• Redness around the eyes

These symptoms do not always indicate glaucoma. However, if glaucoma is present and left untreated it will eventually lead to irreversible blindness.

Your best defence against glaucoma is to schedule regular eye exams with your optometrist. Qualified medical professionals can identify glaucoma and other eye diseases before they severely impact your vision.
