Optical Coherence Tomography Test (OCT Scan)

OCT ScanAn OCT scan utilizes one of the most exciting pieces of eye care technology to enter the Optometry / Ophthalmology world. Unionville Optometry is proud to be one of the only optometry clinics in Markham Ontario to have an OCT scanner (Optical Coherence Tomography).

An OCT eye exam is used in the diagnosis and management of Diabetes, Glaucoma, Macular Degeneration, and many other ocular diseases affecting the Retina and Optic Nerve. The OCT directly measures the health of the tissue inside the eye, and is one of the most important eye care tools used to detect eye disease and prevent vision loss.

Who needs an OCT scan?

  • Diabetic Patients: For a diabetic patient a regular OCT eye exam can help with the early detection of diabetic retinopathy; a cause of permanent blindness when left untreated.
  • Glaucoma: The OCT is used to monitor patients with glaucoma regularly. An OCT eye exam can determine glaucoma disease progression and efficacy of treatment.
  • In patients at risk of developing glaucoma, an OCT scan can be used to detect the disease BEFORE it causes vision loss. Vision loss can be preventable.
  • Patients with Macular Degeneration (and those at risk): Macular Degeneration affects a portion of the retina responsible for central vision, the ability to see directly in front of you, and the only place where we are capable of 20/20 vision. Changes to the macula must be identified as early as possible. Early diagnosis using the OCT eye exam is critical to begin immediate treatment. The stable form of the disease needs to be monitored closely. In most cases, you will not notice when you have progressed to the more serious WET form.
  • Unexplained Vision Loss: In patients with decreased vision that cannot be corrected with prescription eyeglasses, a scan can detect many ocular diseases that could be the cause of unexplained vision loss.

As a part of your comprehensive eye examination, our eye specialists at Unionville Optometry will determine if you require an OCT eye scan.

We service patients from communities throughout the Greater Toronto Area including Markham, Stouffville, Newmarket, North York, Vaughan, Richmond Hill and Pickering, among others.

Frequently Asked Questions

What is an OCT eye scan?

An OCT eye scan takes a comprehensive, non-invasive image of the back of the eye including the optic nerve and retina layers using an Optical Coherence Tomography scanner. The image helps eye doctors to accurately examine, diagnose and treat certain eye diseases like macular degeneration and glaucoma.

How long does an OCT scan take?

It takes less than a minute to take a non-invasive OCT eye scan of both eyes.

Do I need an OCT scan?

OCT scans are non-invasive and utilize a safe spectrum of light to capture accurate images of the back of the eye. Along with early disease detection and diagnosis, OCT eye scans help to monitor the health of the eye as the patient ages.

Can an OCT replace a retina scan?

A retinal scan takes a digital image of the entire eyeball, whereas an OCT eye scan captures the optic nerve and different layers of the retina in 2D and 3D images. Retinal scans and OCT scans both have their advantages and are beneficial in helping to detect, diagnose, and treat various eye diseases.
