OCT
scans
At Corry & Christie we can now offer the option of an OCT scan as part of your eye examination.
In addition to providing a more comprehensive scan of your ocular health, this helps us to track any changes in your eyes when you visit us in the future.
In particular, it can help us detect any underlying eye health conditions such as glaucoma, diabetic retinopathy and age-related macular degeneration much earlier than we would have been able to previously.
What is an OCT scan?
OCT stands for Optical Coherence Tomography and is a scan that allows us to see beneath the surface of the eyes, so we can assess their health in greater detail.
The scan produces a 3D image of the retina at the back of the eye and the different layers within it. We can then measure the thickness of these layers, getting a greater understanding of your eye health.
Who needs an OCT Scan?
Even if your vision and eye health are perfectly fine, an OCT scan is always beneficial. We recommend taking an OCT if you are aged 40 or older. It will help keep track of your health and safeguard it. An OCT scan allows Optometrists identify many eye conditions including:
- Glaucoma
- Diabetic retinopathy
- Age-related macular degeneration
- Macular Holes
- Cystoid Macular Oedema
- Central Serous Retinopathy
- Epiretinal Membrane
Are there any OCT eye test side effects?
An OCT scan is a safe and non-invasive, and there are no side effects or risks associated with the procedure.
How does an OCT scan work?
An OCT scan uses light waves to build up a 3D image of the eye, in much the same way that an ultrasound scan uses sound waves. It is completely painless and will only take a few moments so you don’t need to worry.
During the scan, you will be asked to place your head on a chin rest in front of the OCT scanner. It will scan both your eyes and there will be a flash of light as it takes the images.
