OCT Scan (Optical Coherence Tomography)

What is an OCT Scan ?

OCT (or Optical Coherence Tomography) is a non-invasive imaging technique.

OCT uses light waves to take cross-section pictures of your retina (50,000 per second!).

It is very similar to how an MRI scan would produce high-resolution images of internal organs without touching the body. With OCT, we can see each of the retina’s distinctive layers and can also build a 3-dimensional representation of each individual eye; and all within a matter of seconds!

At Macroom Opticians, we invest in the latest technology to ensure you receive the most comprehensive eye examination possible. We are delighted to have recently acquired the latest state of the art retinal scanning device, an OCT Scan (Optical Coherence Tomography)

What eye conditions is the optician scanning for?

Some of the conditions that can be detected and monitored using OCT include the following:

Age-related Macular Degeneration (AMD)

Age-related Macular Degeneration (AMD) : previously at Macroom Opticians, we could detect gross signs of AMD. For more information on AMD ,click here

We now have the capability to detect these signs with much greater resolution and actually measure their size and depth. Furthermore, we can now monitor progression.


Glaucoma : is a progressive eye condition that can lead to vision loss if not detected and treated in time.

It is a very common eye condition generally affecting people over the age of 60. For more information on Glaucoma , Click here

OCT examination is proving to be extremely helpful in detecting glaucoma in its earliest stages.


Diabetic Retinopathy

Diabetic Retinopathy : OCT is extremely useful in monitoring any diabetic retinopathy that may be present. It enables very early detection (and distinction) of retinopathy which helps improve referral strategy.

Macular Hole

Macular Hole, central serous retinopathy, vitreomacular traction and so much more…..

If you would like the OCT scan to be included as part of your already comprehensive eye examination, please advise at the time of booking.

It is not currently covered by PRSI or medical card optical benefit schemes. It is advisable for you, whether or not you have an ocular condition.
