What is OCT?

 

What is OCT? Ocular Coherence Tomography is an advanced eye scan for people of all ages. Similar to ultrasound, OCT uses light rather than sound waves to illustrate the different layers that make up the back of the eye. This particular 3D OCT unit captures a digital photograph of the surface of the eye at the same time and this can be cross-referenced across any areas of concern.

 

The major benefit of this state of the art machine is that it allows your optometrist to see both the back of your eye, and a three dimensional image to look beneath the surface of the regular retinal image. Never before, has it been easier to find out the exact state and location of a particular eye condition. Your optometrist can review the images on a PC screen and pinpoint areas of concern by digitally peeling the layers back until they define what it is that they have identified as requiring further investigation.

 

 

How is chronic glaucoma detected?

There are few tests that can help detect glaucoma. These are:

 

  • Measuring the pressure inside the eye - often a puff of air or a special contact 'tonometer'

  • Examination of you 'visual field' - usually, a machine where you press a button when you see lights in your peripheral vision

  • Examination of your optic nerve by your optometrist.

 

All these tests are very straightforward, don't hurt and are be done by our optometrists at the practice.
