OCT Scanning

What Is Optical Coherence Tomography (OCT)?

With OCT, we can see each of the retina’s distinctive layers. This allows us to map and measure their 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 to expect from an OCT Scan

Preparation

At the start, you will be seated directly in front of our state-of-the-art OCT equipment. During the entire test, you will keep your head still with your chin resting on the chin rest and your head firmly against the instrument’s head band. You can blink normally. It takes a few minutes to acquire the images.

Examination

When the examination begins, a blue cross will appear in the instrument. You will be asked to stare at the centre of the blue cross during the entire examination. Your Eye Opener examiner will move the instrument toward your eye without touching you. At a safe distance from the eye, we are able to produce a clear image of your retina or optic nerve head. A safe light beam scans the most important structures.

After the examination

After the examination, your vision will not be impaired and you can drive as usual.

Are there any side effects of OCT testing?

The OCT is a non-invasive technology. It allows for the imaging of the retina without touching the eye. The only discomfort you may feel is a flash of light when the OCT records the scan of your eye. The testing takes only a few minutes and the results are available immediately, which allows the treating Eye Opener ophthalmologist to discuss the results with you and to provide the best treatment possible for your condition.
