In the same way that ultrasound uses high frequency sound waves to map body tissue, the reflections of light waves are used to map an image of the inner most layer of the eye interior. Using eye-safe light that is near the infra-red spectrum, OCT technology is very unlikely to cause any damage to the interior of the eye while testing takes place.
The test is non-invasive and does not usually require dilating drops. It involves keeping the eye as still as possible while looking at a fixation light inside the machine. Images are seen immediately on a nearby screen so that your optometrist can check the deep layers of the retina where the early stages of Macular Degeneration and eye disorders can start.
A normal retina shows up in the scan as regular, uninterrupted layers but if there is any damage the layers are disrupted from this healthy pattern. This can easily be seen by the optometrist using OCT technology and treated when caught early.
A regular OCT scan is recommended for all patients over 60 and those in high risk groups, with a scan at least every 2 years. For even more in-depth analysis, ask for a scan on our latest Optos UWF Imaging equipment, available now at Insight Optometrists, Indooroopilly.

Who should have 3D OCT Imaging?
3D OCT Imaging is recommended every 2 years, conducted within your regular eye health examination and sight check. It should be carried out annually for anyone with symptoms or history of eye diseases or disorders.
The OCT test does not usually require dilating drops and involves sitting comfortably in front of the digital scanning equipment, with the head steadied on a chin rest. Keeping the eye as still as possible, you will be asked to look straight at a light inside the machine. This scanner works in a similar way to an infrared barcode scanner, where the back of your eye is mapped safely using controlled, harmless lightwaves.
