Glaucoma Treatment in Toronto

Book Appointment

We Are Toronto’s Glaucoma Treatment Experts

Glaucoma is one of the leading causes of blindness in Canada. Having regular, comprehensive eye exams is the best way to detect glaucoma and slow or even prevent vision loss.

Glaucoma is sometimes called “the silent thief of sight” because it often progresses slowly and without symptoms. By the time symptoms are noticeable, the disease has likely reached an advanced stage, causing significant damage to your sight. 

Make sure glaucoma does not rob you of your sight. Book an appointment for a comprehensive eye exam today.

What Is Glaucoma?

Glaucoma is a group of eye diseases that are characterized by high intraocular pressure. The high pressure is often caused by increased fluid buildup in the eye. Eventually, this causes damage to the optic nerve

Your optic nerve is responsible for transmitting information from the eyes to the brain. When it becomes damaged, irreversible vision loss and even blindness can occur.

While not everyone with high pressure inside their eye will develop glaucoma, it’s still important to monitor your ocular health if increased pressure is present.

There are several types of glaucoma.

Types of Glaucoma

This is the most common type of glaucoma, accounting for 90% of the cases in Canada. If too much of the eye’s natural fluid, called aqueous fluid, is produced or trapped in the eye, pressure can build up, damaging the optic nerve.

Less common than open-angle glaucoma, acute angle-closure glaucoma is a medical emergency that can cause vision loss within a day. It occurs when the drainage angle between the cornea and iris becomes too narrow.

Angle-closure glaucoma can also be a chronic condition. In this case, it takes weeks or years for the drainage angle to close.

People with normal-tension glaucoma have intraocular pressure that falls within the normal range but still sustain damage to their optic nerve. It may be caused by reduced blood supply to the optic nerve or an overly sensitive optic nerve.

If injury, infection, or trauma to the eye occurs, intraocular pressure can rise, leading to secondary glaucoma.

Risk Factors For Glaucoma

There are several risk factors that might increase your susceptibility to glaucoma. These include:

If any of these risk factors apply to you, it is important that you make an appointment for a comprehensive eye examination.

Recognize & Prevent Glaucoma

Generally, glaucoma impacts the peripheral (side) vision but can rapidly advance to damaging central vision if left untreated. Glaucoma cannot be prevented, but it can be managed, and the impacts can be reduced.

Our practice uses applanation tonometry to measure your intraocular pressure. This test measures the amount of pressure needed to gently flatten the cornea. 

Anyone can get glaucoma, but people with diabetes are nearly twice as likely to develop open-angle glaucoma than those without diabetes.

Glaucoma Diagnosis

If you’ve been diagnosed with glaucoma, our eye care team will work closely with you to help you manage your disease. We are with you every step of the way to protect your vision and maintain your quality of life. 

We will have you visit us for regular glaucoma check-ups on top of your annual eye exams. During this visit, we check your vision, ask you about irritated eyes, and discuss your concerns. We may also take this time to adjust your treatment plan, if necessary. 

Many patients experience ocular surface diseases due to their glaucoma medications. But we want your eyes to remain happy and healthy, so we try different medications, add supportive drops, or begin dry eye treatment to provide you with long-term comfort. Any medications you are prescribed will be sent directly to your pharmacy.

If you have a concern about your glaucoma or vision, you can book an urgent glaucoma appointment (within 48 hours) between your regular exams. 

Don’t hesitate to protect your eyes. Please call us soon to schedule an appointment.

I couldn't be more enthusiastic about Dr. Korkis -- in fact, i think she may have saved the vision in my right eye. I went for a routine eye exam, she diagnosed a possible retinal tear, and through her contacts I was seen by a retinologist only a few hours later. He found a large tear and lasered it on the spot. (He failed to offer any follow-up advice -- although he did schedule another appointment -- but when I called Dr Korkis after the weekend, she immediately told me what I needed to know. In addition to her manifest diagnostic skills, she is friendly, personable, and very efficient. I am so glad to have found her.

We have been using this clinic for many years. The place gives you immediate confidence when you enter and know that you have arrived in a professional environment. Dr. Neel Vyas heads this place. He treated me with utmost care and professionalism. He has added new test equipment to do a diagnosis of many kinds. I will continue to visit him because I know the diagnosis will be accurate. The reception staff is quite friendly too. The place is clean, and they display all designer eye glasses for one to choose. Price is very reasonable. I compared it, and I know this clinic is not overcharging me. One more thing: They display artful paintings and photographs for you to enjoy while waiting your turn.

I recently experienced a very painful and scary corneal ulcer that appeared out of nowhere. I had never been to this clinic before but I called on a Saturday as an emergency when my symptoms first started. It ended up being an almost 2-month ordeal that I had to deal with and the care I received here was incredible! Both Dr. Korkis and Dr. Vyas were friendly and caring and were diligent about following up with me to ensure I was healing properly. The front desk staff were also very friendly and helpful! I highly recommend this place for eye care!
