Glaucoma is a progressive eye disease that causes damage to the optic nerve. Although it’s usually associated with high intraocular pressure (IOP), there is a form of glaucoma that results even when IOP is within the normal range (normal-tension glaucoma).
Although those over 60 are at higher risk of developing glaucoma, it can occur at any age. Because many forms of glaucoma progress with no early symptoms, early detection is crucial for protecting your ocular health and vision. In many cases, if glaucoma is caught and managed early enough, vision loss can be entirely prevented.
Open-angle glaucoma (also known as primary or chronic) is the most common form of glaucoma. It occurs when the fluid in your eyes (the aqueous humour) can’t drain properly, causing your eye’s internal pressure to slowly rise. This form of glaucoma progresses gradually and will require life-long management.
This condition rarely exhibits symptoms in its early stages, so many patients don’t realize something is wrong until they have already experienced vision loss or even blindness.
Angle-closure glaucoma (also known as acute or narrow-angle) is a rare form of glaucoma that develops suddenly and painfully. It occurs when the iris expands outwards and blocks the drainage canals (the angle between the cornea and the iris), resulting in a sudden increase in IOP.
Symptoms of angle-closure glaucoma are very noticeable and damage occurs quickly. Symptoms include:
NCT, or the “air puff test,” uses a puff of air to measure your eye’s internal pressure. NCT is an easy test to screen for glaucoma as there is no contact made. However, it’s not as accurate as other forms of tonometry.
Perkins ultimately works the same as GAT. It uses a tonometer to slightly flatten the surface of the cornea to measure IOP.
Glaucoma is a serious and dangerous eye disease that requires quick action and prompt management. Regular eye exams are essential to early detection, so please book an appointment today.
Visual Field Testing
Optometrists use visual field testing to diagnose, assess, and monitor the progression of glaucoma. The test pulses light around different areas of your peripheral vision. At the same time, your optometrist monitors this test to look for signs of blind spots in your vision, which could be indicative of vision damage caused by glaucoma.
Optical Coherence Tomography
Optical coherence tomography (OCT) scans help your optometrist take a look at your retina’s health. Glaucoma can damage your retina, particularly your optic disc, and an OCT detects this by creating cross-sectional photographs of your retina. OCTs operate similarly to an ultrasound, but instead of using sound to generate images, it uses light directed into your eye.
Our Eye Care Services
Where to Find Us
You can find us on the corner of Colborne Street and Kaiser Crescent.
This was an initial visit. My wife wanted a second opinion since she was having some problems. The staff were friendly and efficient. The Dr. was thorough and great to deal with. Answered all of her questions and treated her completely differently than the optometrist that we have been going to for years. Amazing what an efficiently run business with pleasant people can do for your faith in service providers! There are still a few out there believe me! Thanks!
What a great friendly environment, with 1st class service and cutting edge technology. If “eyes” are important, and they are, then this is THE PLACE!!
I have been going here since their last location (20+ years). Have always been treated very well. Doctors are very knowledgeable and will help you. Excellent service and willing to go the extra mile.
