Catch and Control Glaucoma Before It Causes Irreparable Vision Loss

What is Glaucoma?

Glaucoma is a serious eye disease that damages your optic nerve. The vision loss caused by glaucoma is progressive and irreversible.

Unfortunately, Glaucoma often develops asymptomatically (shows no symptoms) until vision loss has already occurred.

Glaucoma Types & Symptoms

Glaucoma is not a defined disease but rather a group of diseases. There are many types of Glaucoma; the three most common are:

  • Open-Angle Glaucoma – Open-angle is the most common type of Glaucoma. It forms when the eye intraocular pressure (IOP) begins to rise due to clogged drainage canals within the eye.
  • Angle-Closure Glaucoma – Also called acute Glaucoma or narrow angle Glaucoma. This form of Glaucoma is much less common than the Open-Angle variant and is characteried by a rapid rise in IOP.
  • Normal-Tension Glaucoma – Refers to cases where Glaucoma has damaged the optic nerve despite IOP not being high.

Symptoms of Glaucoma

During Glaucoma’s initial development you may not experience any symptoms. The most popular variant – open-angle – happily develops without your noticing it until it is quite developed.

Symptoms include:

  • Blurred vision, difficulty focusing
  • Hazy, cloudy vision
  • Eye pain, often severe (indicates angle-closure Glaucoma)
  • Blind spots or tunnel vision
Diagnosing Glaucoma

The only way to catch Glaucoma before it causes vision loss is to catch it preemptively. During an eye exam we test for Glaucoma using advanced equipment and testing processes (such as OCT Imaging).

An annual eye exam will be sufficient for most people, though if you have a family history of Glaucoma (or other eye diseases) it is recommended you have more frequent eye exams.

Preventative Care Saves Your Vision

It’s difficult for us to properly articulate the importance of preventative eye care. We find it incredibly distressing when people discover the importance of preventative care too late.

We implore you: care for your eyes. If you are an adult with normal vision, have them checked at least once every one or two years- your future self, enjoying the benefits of great eyesight, will thank you!

If you are over age 65, OHIP provides coverage for annual eye exams- please, use it! As well, certain conditions (such as diabetes) also impact your eye sight, and OHIP provides coverage for more frequent eye exams as a result.

Glaucoma Cannot Be Cured, But it Can Be Managed

Unfortunately no cure for Glaucoma exists, though its symptoms and impacts can be managed effectively through eye drops (and in some cases, surgical procedures). In fact, treatment is effective enough that we have to remind our patients to continue their prescribed treatments despite a lack of obvious symptoms.

The most common cause of vision loss from Glaucoma is when patients fail to strictly follow their treatment.
