What is a OCT Scan
When you schedule your routine eye test, you may be forgiven in thinking that your appointment is simply just to test your eyesight. However, Conor has invested in the most up to date Optical Coherence Tomography (OCT) equipment that can provide an in-depth picture of your overall eye health too, including screening for eye disease. This is offered as part of your standard eye examination
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. Conor offers an OCT scan as part of your standard eye examination.
An OCT scan can help your optician to see what’s going on beneath the surface of your eye, providing a picture of the layers of your retina. Conor 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 Does An Oct 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 Conor over the years and having multiple scans, he can notice subtle changes in the thickness of the layers from your history.This can indicate early signs of eye conditions, making it much easier to diagnose, treat and manage
