OCT Scan

An OCT scan is a non-invasive medical imaging technique, which allows us to obtain the mostdetailed information about your overall eye health.

OCT scans are especially helpful for the early detection of the sight-threatening eye disease, glaucoma, which shows few symptoms until it is advanced, as well as age-related macular degeneration, retinal detachments, and diabetic retinopathy.

What is an OCT scan?

An OCT scan is a non-invasive medical imaging technique, using light waves to produce detailed 3D images. It is a bit like an MRI scan for the eye. This helps your Optometrist to diagnose and manage certain eye conditions, in many cases much quicker and earlier than has been previously possible. OCT imaging systems are used to provide details of the back of your eye (the retina), and the OCT machine that we have at Eyeworks is also able to produce images of the front part of the eye (the cornea, iris and surrounding structures). One of the many advantages of an OCT scan over previous methods of retinal imaging is that the OCT scan can detect changes below the level of the retina long before they become visible on the retinal surface. This can greatly assist in the early detection and monitoring of various eye diseases such as Glaucoma, Diabetic Retinopathy, Age Related Macular Degeneration and many other conditions. An OCT scan is often the best way to pick up these conditions as early as possible, even before they are affecting your sight or giving rise to any noticeable symptoms, which in turn means any required treatment can be much more effective. Because they are so useful in detecting and monitoring a large range of eye conditions, you will find OCT machines in most hospital eye departments, and we are delighted to now be able to offer this sort of eye scan at Eyeworks.

Why should I have an OCT scan?

Having an OCT scan in combination with your normal eye test will allow us to obtain the most detailed information about your overall eye health. Most OCT scans that we do are entirely normal, but it is a fact of life that the risk of many eye conditions increases with age. Having an OCT scan however is often the best way to pick up these conditions as early as possible, and early detection will lead to timely and more effective treatment, and better outcomes for the health of your eye and for your vision.

What happens during my scan?

You are simply required to sit in one position and look at a green fixation target. The scan will not touch your eye or blow air at your eye, and is quick and entirely painless. An OCT scan will not affect a pacemaker or have any other negative after-effects.

How long does it take?

The OCT scan is a very quick process and most scans take only around 30 seconds per eye. Sometimes we will do some extra scans which may take a little longer, but even these are generally only a minute or two per eye, and again entirely painless.

What happens to my images?

Your images will be stored on file, so that when you see us again for your next appointment we can compare your images to see if anything has changed. Sometimes, if we need to refer you for further investigation we may send copies of your OCT scans to your doctor or to the hospital eye clinic.

Seeing through the retina

Traditional examination of the back of the eye (the retina) involved looking for signs of change on the surface. Thanks to OCT scans we can see through the surface and examine all the layers of the retina. Being able to identify and monitor abnormality within these layers is essential for early detection and diagnosis of some of the major causes of visual impairment and blindness. This means treatments can be made available at the earliest possible moment.

OCT scans and why we recommend having one will always be explained to you at the time of your eye test, but if you have any further questions, concerns or require any further information, please do not hesitate to ask. Contact us if you have any questions about OCT scans before booking in for an appointment.
