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,

Ontario will be entering LOCKDOWN on December 26 @12:01AM by order of the Government of Ontario for at least 28 days. Please note that medical care including Optometry services are NOT impacted by these changes.

We will continue to operate following Public Health protocols including screening, PPE, handwashing & sanitizing as well as maintaining physical distancing where possible.

We are open throughout the holiday season (Closed Dec25-27 and Dec31-Jan3) for orders, with very limited in person care. We will be open for full care on Jan 4. We will reserve two urgent care appointments each day during the province-wide lockdown to help reduce the number of eye related emergency room visits for our current patients.

If you are experiencing an eye emergency (loss of vision, double vision, distortion to vision, ocular pain, photosensitivity or other visual symptoms) please contact the office at 519 822 2710 for advice before presenting to the emergency room.
