OCT 3D Scan
We have recently invested in a revolutionary piece of diagnostic equipment that can detect a number of key eye conditions, such as GLAUCOMA, age related macular degeneration (AMD) and DIABETIC RETINOPATHY during a routine eye test. This piece of equipment is called a 3D Optical Coherence Tomography system (3D OCT). Ocular Coherence Tomography is an advanced eye scan. Similar to ultrasound, OCT uses light rather than sound waves to illustrate the different layers that make up the back of the eye.
Why is it important?
The major benefit of this state of the art examination is that it allows your optometrist to see both the back surface of your eye and the layers below the surface in 3D. This means we can then screen for various eye conditions as well as monitoring existing conditions.
What are we looking for?
Any changes in the layers of the retina. These changes can be caused by GLAUCOMA, DIABETES, AGE RELATED MACULAR DEGENERATION or HIGH BLOOD PRESSURE. It is particularly important for those who have any family history of eye problems to have screening for any problems. Even small changes in the retina can be sight threatening, so the earlier it is noticed the better.
How does it work?
It is a quick painless procedure, similar to the previous 2D retinal photo you may have had.
Your optometrist can then review the images on a PC screen and pin point areas of concern by digitally peeling the layers back until they define what it is that they have identified as requiring further investigation.
What if something is detected?
Using this machine, your optometrist can more confidently diagnose, manage and refer you to a specialist for further treatment, should this be required.
I already have a 2d photo whats the difference?
The 2D retinal photograph you have had previously only looks at the SURFACE of the retina. This new 3D OCT SCAN is able look beneath the surface. The images show how quite different a 3D OCT scan is.
