Glaucoma Test

Glaucoma is the generalized name for a group of eye diseases that damage the optic nerve of the eye, preventing the eye from sending accurate visual information to the brain.

Glaucoma tests are designed to test your eyes for one of the key symptoms of the disease—increased eye pressure—however only a comprehensive eye exam can reveal whether or not you have glaucoma.

Increased pressure inside the eye is often a key indicator of glaucoma, though not exclusively so. Eye doctors can use a number of tests for eye pressure, but will, by default, check for signs of glaucoma as part of a detailed examination of the retina—the light sensitive area at the back of the eye responsible for processing images.

How Does Glaucoma Testing Work?

A glaucoma test is usually part of a routine eye exam.

Both types of glaucoma tests measure internal pressure of the eye.

One glaucoma test involves measuring what happens when a puff of air is blown across the surface of the eye. (A puff test) Another test uses a special device (in conjunction with eye-numbing drops) to “touch” the surface of the eye to measure eye pressure.

While increased eye pressure is a key indicator of the disease, it does not necessarily mean you have a glaucoma diagnosis. In fact, the only way to detect glaucoma is to have a detailed, comprehensive eye exam that often includes dilation of the pupils.

So “true” glaucoma testing actually involves examining the retina and optic nerve at the back of the eye for signs of the disease.

Glaucoma can cause slight to severe vision loss, and is often discovered only after the disease is present—that’s why glaucoma testing is so important.

Dear Patients,

Today, under directions from the College of Optometrists of Ontario, we have made the difficult decision to immediately suspend all non-urgent care,  due to the COVID-19 pandemic. Our doctors will still be accessible for ocular emergency assessments case by case. The clinic is closed.

All non-urgent appointments will be canceled and rescheduled for a later date. For urgent care please DO NOT call or come to the clinic, but send an email to: info@miltoneyecare.ca for appropriate triaging.

For patients who need to order contact lenses, please continue to place your order request on our website at www.miltoneyecare.ca. We encourage a 6-12 months’ supply of contact lenses to be ordered.

What consists of an emergency: Ocular Emergencies require an urgent visit within 24-48 hours. Please email our office should you experience:

  1. Chemicals splashed into the eye within the last hour
  2. Sudden loss or decrease in vision, or the appearance of a cloudy veil in front of the eye
  3. Foreign body in the eye, ocular injury or forceful trauma to the eye or surrounding area
  4. Sudden onset of halos around lights; especially if associated with a red painful eye or brow
  5. Sudden onset of flashing lights or floaters
  6. Sudden onset of double vision
  7. Red eyes with pain, light sensitivity or pus discharge
  8. Swelling of eyelid

If you are not sure if you are experiencing an ocular emergency please email our office at info@miltoneyecare.ca

 As this situation evolves, Milton Eye Care is committed to providing updates to our patients. While this is a difficult time for all, we are aspired by our patients who have taken their own personal measures to protect our most vulnerable. Thank you for your understanding. Please stay safe and healthy.
