OCT – Ocular Coherence Tomography

A long word for an amazing advance in eyecare!

You may have had an eye examination where you had a 2D picture taken of your eyes using a fundus camera, it’s an amazing thing to see – your whole retina in a large colourful picture. We can show you how your eye works and explain if there is anything we need to keep a check or if you need treatment.

This is always done at Park Vision! However…

Now with this very clever machine we can not only look at the back of your eye ….we can look at a 3D image and take a peek through the layers in your retina!! This is not possible with a normal eye examination. It works similar to an ultrasound but uses light rather than sound waves.

An OCT scan is quick, painless and doesn’t need eye drops. The results will be shown to you immediately and you will be able to see exactly how healthy your eyes are.

With this technology, we can see if problems in your central vision are occurring BEFORE they have had chance to affect your vision!

Early detection can mean early treatment for eye conditions such as wet & dry age related macula degeneration (ARMD), glaucoma, retinal detachment and diabetic retinopathy.

Early detection can mean prevention of sight loss!

If you are over 40 an OCT will give you complete peace of mind of your eye health- it is particularly recommended for patients who want the most accurate, in-depth eye examination but especially for anyone who has:

Family history of glaucoma

Half of all glaucoma patients are not aware that they have the condition – a hereditary disease often referred to as ‘the thief of sight’. If you have a family history of this condition, it is especially important to have regular checks as damage to the eye is irreversible. Until the disease has reached an advanced stage, the brain can compensate for blind spots within the vision, by filling in the gaps. This can mask the condition for some time, so regular screening is vital.


With half of patients being unaware that they have diabetes, the resulting loss of vision caused by the disease is a serious concern to health care professionals. With early detection and treatment of diabetic retinopathy, the chances of sight loss can be reduced for nine out of 10 patients.


It is estimated that by the age of 60 half of the population will have some degree of cataract. A cataract can make it difficult for your optometrist to assess your retina for any other signs of disease using traditional fundus photography, so you may only become aware of any other problems in your eye once the cataract has been removed.

History of ARMD, diagnosed ARMD, as an extra monitor alongside ophthalmological visits

Age-related macular degeneration (AMD) is the cause of one in two cases of serious sight loss, robbing the person of their central vision. Once this happens, simple activities like driving, watching TV and recognising faces can become very difficult.

 – Vitreous detachment and related conditions

 – Concerns regarding their vision

OCT is included in the Advanced Eye examination but this fantastic eye scan will give any patient complete peace of mind regarding their eye health. If you would like an OCT at your next eye examination please ask when you book your appointment, or feel free to discuss this with Michelle at your next visit.
