Optical Coherence Tomography

Optical Coherence Tomography in Toronto

Optical Coherence Tomography offers patients one of the most advanced ways to evaluate and protect their vision. This non-invasive imaging technology uses light waves to produce cross-sectional images of the retina, revealing details invisible during a standard exam. By identifying early changes linked to glaucoma, diabetic retinopathy, or macular degeneration, OCT makes it possible to take action before vision loss occurs.

 

Our eye care expert team uses this technology to deliver accurate assessments, guide treatment decisions, and provide peace of mind for patients concerned about their long-term eye health. Every scan is interpreted with precision and explained clearly, so you fully understand your results and next steps.

What Is Optical Coherence Tomography (OCT)?

Optical Coherence Tomography is a specialized imaging method that uses light to create high-resolution, cross-sectional pictures of the retina—the thin, light-sensitive tissue at the back of your eye. Unlike traditional eye exams that focus primarily on vision clarity, OCT goes deeper by revealing the individual layers of the retina and optic nerve.

Because these images are so detailed, even microscopic changes that signal early disease can be detected before symptoms appear. This is particularly valuable for patients with risk factors for vision-threatening conditions. With Optical Coherence Tomography, we can monitor subtle changes over time and adjust care plans quickly, helping prevent long-term complications.

Why is OCT Important for Eye Health?

Many eye diseases develop quietly and without pain, progressing unnoticed until vision loss becomes permanent. Conditions such as glaucoma, diabetic retinopathy, and age-related macular degeneration can damage the retina long before patients experience any symptoms. By offering Optical Coherence Tomography, we can identify these issues at their earliest stage, when treatments are most effective.

These OCT scans give our patients a unique advantage in preventive care. They allow our eye clinic to track changes in the optic nerve, identify swelling or thinning of the retina, and detect fluid or bleeding caused by systemic conditions like diabetes. By pairing OCT with a Best Eye Exam Toronto, we provide both a complete vision assessment and an in-depth look at your overall eye health. This ensures that you are not only seeing clearly today but also protecting your sight for the future.

Who Should Have an OCT Scan?

While OCT scans are valuable for nearly everyone, certain groups benefit the most from regular testing. Adults over 40, individuals with a family history of glaucoma or macular degeneration, and patients living with diabetes or high blood pressure should strongly consider adding OCT to their routine check-ups. Those experiencing sudden or unexplained vision changes, such as blurriness, distortions, or dark spots in their vision, can also benefit from this test.

What to Expect During an OCT Scan?

An OCT scan is simple, painless, and takes just a few minutes to complete. There is no need for preparation, and patients remain comfortable throughout the process. During the scan, you will be seated in front of the OCT machine with your chin resting on a support. The device uses light waves to scan the back of the eye without touching it, creating high-resolution images of the retina.
Once the scan is finished, our team will review the results with you immediately. If we detect any signs of disease, we will explain the findings in detail and create a personalized treatment or monitoring plan. This patient-focused consultation ensures that you leave the appointment with a clear understanding of your eye health and next steps.
