Spectral Domain Ocular Tomograph (OCT)

OCT is an extremely advanced 3D scan of the eye for people of all ages.  It works in a similar way to ultrasound but uses light waves rather than sound waves.  This allows us to illustrate the different layers that make up both the front and back of the eyes.


How Does It Work?

Using light reflected from the front or the back of the eye, the OCT creates a highly detailed picture in two or three dimensions.  This can give your optometrist a view of your eyes on a microscopic level.  The major benefit of this is that it allows us to literally see beneath the surface, allowing them to view structures and sections of the eye that would be otherwise invisible.

Never before has it been easier to find out the exact state and location of a particular eye condition.  We can then review the images on a PC screen and pin point areas of concern by digitally peeling back the layers until they define any areas requiring further investigation.

Having an OCT scan taken is a quick and easy process.  Nothing comes into contact with the eye and it is completely pain free.  You will be asked to look at a target and the scan will be taken in less than a minute, much like getting a photograph taken


Which Conditions Can Be Detected Through OCT?

By utilising OCT scanning, we can now detect a number of key eye conditions, such as glaucoma, age-related macular degeneration (ARMD) and diabetic eye changes during a routine eye examination. These conditions can often be detected earlier than would be possible without these images.
