( Dr. Kathy Cao, Local Ophthalmologist Toronto, ON ), may talk about some of the conditions and some of the treatment options shown on the videos. Always talk with your Local Ophthalmologist about the information you learnt from the videos in regards to treatments for What is Glaucoma? and procedures the Local Ophthalmologist could  perform and if they would be appropriate for you. Remember good information is the corner stone to understanding your condition or disease.

local ophthalmologist is different from a local optometrist in that an optometrist doesn’t perform surgery. If you have a condition known as ocular hypertension, which is a result of high ocular pressure, your risk of developing glaucoma increases.Your optometrist or ophthalmologist may want to lower your IOP as a preventative measure.

Please contact ( Dr. Kathy Cao, Local Ophthalmologist Toronto, ON ) to enquire if this health care provider is accepting new patients.Patients are often concerned that an injection of material into their eye will be a painful or scary procedure. In fact, after the first or second injection, patients become quite at ease with the idea that they will have these injections, Following an intravitreal injection, you may feel pressure or grittiness in the eye, slight bleeding on the white of the eye and floaters in your vision. These are temporary and normal. As glaucoma progresses, it damages more and more of your optic nerve fibers, leading to vision loss. With primary open-angle glaucoma, the fluid can’t effectively flow back out of your eye. Angle-closure glaucoma occurs when the iris of the eye closes off the drainage angle completely, causing an increase in IOP pressure and damage to the optic nerve.

Glaucoma is a condition where there is increased pressure within the eyeball, causing damage to the optic nerve and gradual loss of sight.  If glaucoma is detected early preventative measures can be taken to save vision loss.

Cataracts can affect both eyes or just one, and some patients experience mild symptoms, while others can barely see any shapes or movements. Cataract symptoms include blurry vision, haloes, sensitivity to bright lights, decreased night vision, frequent changes in eyeglass prescriptions, and faded colours.

Glaucoma is a group of eye conditions that primarily affect the optic nerve, which transmits visual information from the retina to the brain. In most cases of glaucoma, damage to the optic nerve is associated with increased pressure within the eye, known as intraocular pressure (IOP). However, glaucoma can also occur without elevated IOP, known as normal-tension glaucoma.

When the pressure inside the eye becomes elevated, it can cause compression and damage to the retinal fibers that make up the optic nerve. These fibers are responsible for transmitting visual signals to the brain, allowing us to see.

    Worst clinic we have ever visited. Absolutely agree to the other google reviewers "AVOID THIS CLINIC AT ALL COSTS!!!! " My 77 years old mother-in-law visited Dr. Kathy Cao Eye clinic back in Jan. Dr. Cao didn't give any medicines or treatments to take care of her symptoms and concerns. Instead, Dr. Cao spent most of the time persuading my mother-in-law to have a cataract surgery, and presenting lens options , while my mother-in-law former eye specialist told her there is no rush to do a cataract surgery ...... Anyway, we gave Dr. Cao our full trust, did all the required tests & measurements, paid $550 for deposit ($1,610 cost in total for surgery), and booked a surgery with Dr. Cao in May, till ridiculous things happened later. 10 days before the scheduled surgery date, Annie Tan, assistant to Dr. Cao, suddenly called us to do another measure because the measures that were done three months ago were not success. And, "BTW, because it usually takes 15 days to order the lens from the vendor, Dr. Cao can't do your surgery on that day". Come on! There are more than three months between Jan and May that can re-do the measures. Now you are telling us that you are not able to have the lens ready for surgery on time? What a poorly running clinic! We were so frustrated because the delay of surgery will cause conflicts with our family travelling plan and other scheduled unchangeable specialist appointments. Plus, we no longer trust Dr. Cao and her team - they don't have the capability to properly manage their "business". As a result, we had to completely cancel the surgery. It is their fault, so obvious! However, Dr. Cao and her team did NOT express any apologies! And, Dr. Cao refused to reimburse the $71.57 expense we paid for eye-drops, though the only usage of these eye-drops are for surgeries. Okay, maybe we should not have agreed to do the cataract surgery at the very first visit because it is not so necessary! Okay, given the average google review for this clinic is only 2.7, we definitely should have avoided it at all costs! Hey, Dr. Cao, be professional! Please treat your patients as human beings, not only a source for profits and business!
