Optical Coherence Tomography

We are using the latest in optical technology, the Maestro2 Topcon 𝐎𝐂𝐓 (𝐎𝐩𝐭𝐢𝐜𝐚𝐥 𝐂𝐨𝐡𝐞𝐫𝐞𝐧𝐜𝐞 𝐓𝐨𝐦𝐨𝐠𝐫𝐚𝐩𝐡𝐲) machine. Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of the back of the (the retina), including the optic nerve and macula.

With OCT, we are able to see each of the retina’s distinctive layers. This allows us to map and measure its thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina. These retinal diseases include age-related macular degeneration (AMD) and diabetic eye disease.

What happens during OCT?

To prepare you for an OCT exam our optometrists may or may not put dilating eye drops in your eyes. These drops widen your pupil and make it easier to examine the retina.

You will sit in front of the OCT machine and rest your head on a support to keep it motionless. The equipment will then scan your eye without touching it. Scanning takes about 5 to 10 minutes. If your eyes were dilated, they may be sensitive to light for several hours after the exam.

What Conditions Can OCT Help Diagnose?

OCT is useful in diagnosing many eye conditions, including:

OCT is often used to evaluate disorders of the optic nerve as well. The OCT exam helps us see changes to the fibres of the optic nerve. For example, it can detect changes caused by glaucoma.

The OCT machine can also be used to scan structures of the front of the eye including the cornea and iris.

OCT relies on light waves. It cannot be used with conditions that interfere with light passing through the eye. These conditions include dense cataracts or significant bleeding in the vitreous.

OCT scans are painless, non-contact, safe and very quick, like an ultrasound.
