What is OCT?

Optical Coherence Tomography uses low intensity
infra-red light to give a 3D image of the back of the
eye.  It shows not only the surface but also the depth
of the structures.  It is similar to using ultrasound and
creates an image not unlike an MRI or CT scan.

The light levels are very low, the scan takes seconds to
acquire and is totally painless.  All you need to do is look at a light, keep your eyes still and not blink for two
seconds, simple as that!
 

As well as the 3D scan, our instrument also takes a
photograph of the eye in high resolution.  This allows us
to pin point any area of concern to review in depth.

What are the benefits?

The instrument is incredibly good at measuring and
monitoring Macular Degeneration.  It can measure
the thickness of the optic nerves which are affected by
Glaucoma (and compare to an age, gender and

ethnically matched normal).

In both circumstances it can mathematically show any
changes from one visit to the next, working at a level way
beyond the ability of even the most experienced observer
with normal viewing methods.

If there are any changes or abnormalities they can be

monitored by ourselves if appropriate.  Should you need

referral to a hospital the information we provide can help

immensely in aiding the doctor to prioritise the urgency

for assessment/treatment.

Does everyone benefit?

Everyone can have greater reassurance from a more
in-depth examination.  The two main areas where we

see benefits are to people with, or likely to develop,
Macular Degeneration (mainly people aged 60 or over)

and those with a family history of Glaucoma or high

pressures in their eyes.  Diabetics can be monitored and

compared more accurately, which is very beneficial in

the long term.

Do I need to have an OCT scan?

When checking the health of your eye the more
information we have the better the quality of our

decisions will be.  This procedure gives us far more

information to make a decision now, and improves our
ability to compare and notice very subtle changes in the
years to come.

What does OCT cost?

The OCT scan is an additional test and as such is not
part of a standard NHS eye test.  Should you take
advantage of the scan it would be performed before your
standard eye test.  The cost is £35.00.

3 ways to help protect and
maintain a healthy macular.

1. Eat a diet rich in vitamins and  
   minerals, particularly Lutein
   and  Zeaxanthin.  These are
   found in green leafy vegetables
   and in yellow fruits.
    
2. Have regular check-ups including
   the OCT scan to monitor any changes.
    
3. Protect your eyes against damage
   from UV light.  When buying sunglasses
   make sure they have adequate
   UV protection.
