Glaucoma Management

Glaucoma is a group of eye conditions that damage the optic nerve, which is the nerve that connects our eyes to our brain and is responsible for converting light into vision. The damage from glaucoma can ultimately lead to vision loss. Glaucoma is one of the leading causes of blindness, affecting over 450,000 Canadians.

Early detection and management is a key part of glaucoma treatment. At Tonic Eye Care, we offer a complete care approach to glaucoma management, helping patients across Toronto stay ahead of their symptoms.

What are the Symptoms of Glaucoma?

Glaucoma is sometimes called the “silent thief of sight” because it often progresses without noticeable symptoms until significant vision loss occurs. However, these are some of the symptoms that can signal its presence:

  • Gradual loss of peripheral vision, usually in both eyes
  • Severe eye pain
  • Blurred vision
  • Halos around lights
  • Redness in the eye
  • Nausea and vomiting
  • Tunnel vision in the advanced stages


If you experience severe symptoms, seek immediate medical attention, as they can indicate an acute angle-closure glaucoma attack, which is a medical emergency.

Who is Most at Risk?

While anyone can develop glaucoma, the risk increases with age and is more prevalent in Black and Hispanic populations. Some other risk factors of glaucoma include:

  • Diabetes – People with diabetes are twice as likely to develop glaucoma
  • Familial history of glaucoma
  • Far-sightedness (for closed-angle glaucoma)
  • Near-sightedness (for open-angle glaucoma)
  • High blood pressure
  • Very low blood pressure
  • Long-term corticosteroid use
  • Previous eye injury

The Different Types of Glaucoma

Understanding the different types of glaucoma aids in accurate diagnosis and timely treatment.

Open-Angle Glaucoma

The most common type, open-angle glaucoma, occurs when the eye’s drainage canals are open but there is damage to the optic nerve. This can be because of material clogging up the drainage system which leads to increased eye pressure and subsequent nerve damage. Another type of open-angle glaucoma is normal-tension glaucoma. In normal-tension glaucoma, optic nerve damage occurs despite normal eye pressure levels. The exact cause is unknown, but has been hypothesized to be related to poor blood flow to the optic nerve. Open-angle glaucoma tends to progress slowly and painlessly, so can go unnoticed for years before symptoms appear.

Angle-Closure Glaucoma

Angle-closure glaucoma occurs when the drainage angle between the iris and cornea becomes blocked suddenly, causing a rapid increase in eye pressure. Symptoms include severe pain, nausea, and blurred vision. If you are experiencing these symptoms, seek medical assistance immediately. 

Secondary Glaucoma

Secondary glaucoma results from an underlying condition such as eye injury, inflammation, or a tumour, that causes an increase in pressure in the eye. It can also be caused by certain medical conditions or medications, like corticosteroids.

How We Detect Glaucoma

Our clinic is equipped with state-of-the-art diagnostic instruments to ensure accurate and early diagnosis. We use advanced methods and technologies to test eye pressure and get a detailed image of the back of your eye. These tools allow us to monitor changes over time and adjust your treatment plan as needed. For more on our diagnostic services, check out our Eye Exams page.

The Importance of Regular Check-Ups

Early detection of glaucoma is crucial to preventing vision loss. Because glaucoma often presents no symptoms in its early stages, regular eye exams are the best way to catch it early. During these exams, our optometrists will perform a series of tests to check your eye pressure, inspect the drainage angle, evaluate your optic nerve, and test your peripheral vision. These tests help us detect glaucoma before significant damage occurs.

How We Treat Glaucoma

At Tonic Eye Care, we educate our patients and offer the latest treatment options available. Treatments aim to lower eye pressure and prevent further optic nerve damage. Medicated eye drops are usually the first line of treatment, with the general intention of reducing eye pressure. 

For patients who require more advanced care, we can refer you for laser therapy or surgery if needed. Laser treatments such as Selective Laser Trabeculoplasty (SLT) and Argon Laser Trabeculoplasty (ALT) can improve the drainage of fluid from the eye. In more severe cases, surgical options may be necessary to create new drainage pathways for the eye or to help drain fluid.

Working Together in Your Glaucoma Management 

Managing glaucoma is a lifelong process, and we support you every step of the way. We offer continuous care and regular follow-up appointments to monitor your condition and adjust treatments as necessary. Our team provides comprehensive education about glaucoma, helping you understand your condition and how to manage it effectively. We encourage our patients to be active participants in their eye health, recognizing that informed patients are better able to adhere to treatment plans and lifestyle changes that can preserve their vision.

Our optometrists work closely with other healthcare providers, including ophthalmologists and primary care physicians, to ensure patients receive a complete care plan. We stay current with the latest research and advancements in glaucoma treatment to provide the best care possible.

Glaucoma Consultation - Tonic Eye Care & Vision Therapy

What to Expect During a Glaucoma Consultation

Your glaucoma consultation at Tonic Eye Care will involve a comprehensive eye exam and specific tests to assess the pressure in your eye and the condition of your optic nerve. You can expect to receive tests for:

  • Visual acuity
  • Peripheral vision
  • Eye pressure
  • Imaging of the front and back of the eye 
  • Eye muscle function
  • Binocular vision
  • Pupil reaction

During your appointment, your optometrist may administer dilating drops, which will cause sensitivity to light and blur your vision for 2-5 hours. Please arrange for safe transportation home from your appointment, as driving is unsafe until your vision returns to normal.
