Glaucoma Detection & Management in North York
Glaucoma is often called the 'silent thief of sight' because it progresses without symptoms until vision is already affected. Early detection and consistent monitoring are the most effective ways to protect your sight — and that's exactly where we come in.
Symptoms of Glaucoma
Glaucoma often progresses without noticeable symptoms until significant vision loss has occurred. When signs do appear, they can include:
- Gradual loss of peripheral (side) vision, usually in both eyes.
- Blurred vision or halos around lights.
- Eye pain or redness.
- Tunnel vision in the advanced stages.
- Severe eye pain with nausea or vomiting — a possible sign of an acute attack requiring emergency care.
If you experience sudden, severe eye pain with nausea and blurred vision, seek immediate medical attention — it may indicate an acute angle-closure attack.
Who Is Most at Risk?
While anyone can develop glaucoma, the risk increases with age and is higher among certain groups. Common risk factors include:
- A family history of glaucoma.
- Age — risk increases as you get older.
- Diabetes — people with diabetes are about twice as likely to develop glaucoma.
- High or very low blood pressure.
- Nearsightedness (for open-angle) or farsightedness (for closed-angle).
- Long-term corticosteroid use or a previous eye injury.
The Different Types of Glaucoma
Understanding the type of glaucoma guides accurate diagnosis and timely treatment.
Open-angle glaucoma
the most common type, where the drainage canals are open but the optic nerve is damaged, often as pressure builds gradually. Normal-tension glaucoma is a form where damage occurs even at normal eye pressure. It tends to progress slowly and painlessly.
Angle-closure glaucoma
occurs when the drainage angle becomes blocked suddenly, causing a rapid rise in eye pressure with severe pain, nausea, and blurred vision. This is a medical emergency.
Secondary glaucoma
results from another cause, such as an eye injury, inflammation, certain medications, or other medical conditions.
Early Detection Is Key
Don't Wait for Symptoms
Glaucoma is most treatable when caught early. A comprehensive exam checks your eye pressure and optic nerve health.
