OCT Imaging

Spybey Optometrists can carry out a variety of tests and checks to understand both your vision and the physical condition of your eyes, thanks to emerging technology becoming more available.

One such example of this is Optical Coherence Tomography (OCT). This is a hospital-quality scan that can be carried out at our practice, using cutting-edge technology to look more closely at your retina.

So what does an OCT scan do?

Many common eye diseases can creep up on you, without any significant symptoms. So, even if your vision and eyes appear perfectly fine, it’s useful for your optician to gain a full understanding of your overall eye health through additional tests.

In particular, an OCT scan can help to detect eye conditions like glaucoma, age-related macular degeneration and diabetic retinopathy. We recommend an OCT scan even when your eyes are healthy in order to provide a baseline image.

An OCT scan can help us to see what’s going on beneath the surface of your eye, providing a picture of the layers of your retina – we can then map out the layers and measure the thickness. The optic nerve head is also visible at the back of your eye, so an OCT scan can also evaluate any disorders of the optic nerve.

How do OCT’s scan work?

OCT technology uses light waves to take images of your retina; similar to how an ultrasound scan uses sound waves. During an OCT scan, you will be asked to sit in front of a small machine with your chin placed on a support. The instrument can scan your eye without touching it.

The scan is done on both eyes, one at a time. It is completely painless; you may be slightly dazzled by the flash of light that is given off in the machine, as if you have had your picture taken, but this will quickly disappear.

By attending multiple OCT scans over the years, we can notice subtle changes in the thickness of the layers. This can indicate early signs of eye conditions, making it much easier to diagnose, treat and manage.

Booking an OCT examination

Your OCT can be done at the same time as your routine eye examination – we’ll show and the explain the images of your eyes – if this is something which you like to have carried out, just mention it to the practice team.
