OCT and Health Screening
Here at Ray-Lewis Opticians we have invested in a top of the range 3d scanner from Topcon called the Triton and is the only one of its kind in Sheffield.
This technique is essential in observing subtle and progressive changes at the macula (screening for macular degeneration) and at the optic nerve (screening for glaucoma amongst other conditions affecting the optic nerve.) This 3D scanner is capable of showing changes at the back of our eyes before they become apparent on the surface at the back of the eye (such as in a simple retinal photograph.)
Detecting conditions like macular degeneration, glaucoma and diabetes at an early stage allows us to benefit from a much earlier referral to a specialist for management / treatment.

A 3-D scan of the optic nerve at the back of the eye is essential for screening for glaucoma and other conditions affecting the optic nerve. Measuring changes in the optic nerve over time and in conjunction with other tests, e.g. Checking the pressure of the eyes and changes in the visual fields can allow for early detection of glaucoma.
What is OCT?
OCT stands for Ocular Coherence Tomography which is an advanced scan available for people of all ages. It is similar to an ultrasound scan; however, the OCT uses light rather than sound waves to illustrate the different layers that make up the back of our eyes in incredibly fine detail revealing 3 dimensional images of the structures.
The Triton also captures a digital photograph of the back surface of the eye at the same time.
Mr Pramod-Ray Patel can review the images and pinpoint areas of concern by digitally peeling back the various layers until he can define and locate areas that require further investigation.
Who will benefit from OCT?
We encourage every patient to have a 3D scan in conjunction with their first eye examination at Ray-Lewis Opticians, to establish a baseline reference point to allow us to compare any changes observed at subsequent scans.
Your OCT Appointment
At Ray-Lewis Opticians screening for eye health takes approximately an hour which includes tests using the M-POD which measures macular pigment density which is essential in safeguarding the macula against blue light.
Where necessary eye drops are sometimes instilled into the eyes to enlarge the pupils to allow an extensive look to the more peripheral parts of the back of the eye and the examination is concluded using the OCT to take 3D scans of the back of the eyes and where indicated also the front of the eye (if you suffer from Dry Eye or are a Contact Lens Wearer.)
The fee for the OCT appointment is £60.
