Spectralis OCT
John Rose was the first optometrist to introduce Spectralis OCT into the UK market, and is highly recognised and regarded as a pioneer within the optometric community.
The Spectralis OCT 4 Dimensional Eye Examination
What to Expect
The actual scan takes just seconds to carry out. The camera does not touch your eye and there is no bright flash or puff of air. It is a comfortable, non-intrusive and non-invasive procedure. Your full eye test may take 60 to 80 minutes in total.
The SPECTRALIS 4D HD Eye Health Check is much more than your standard sight test. The light beam scans the retina gathering information at different depths of the eye - active eye-tracking produces amazingly accurate 3-dimensional images of the back of your eye, looking for very early signs of glaucoma and other retinal and systemic diseases.

Why?
Why should I have a SPECTRALIS 4D HD Eye Health Check?
Rapid detection and rapid referral for treatment are the key to saving your sight.
It is commonly known that structural change in the eye often occurs long before you might notice any functional change or loss (sometimes by as much as 12 years). The Spectralis 4D HD Eye Health Examination offers you the peace of mind that comes with knowing that your eyes are healthy or that your optometrist will detect the smallest change before you do, thereby reducing the risk of sight loss and improving our patient's lives.
How?
What makes the SPECTRALIS Eye Health Check 4-Dimensional?
IT MEASURES CHANGE OVER TIME, time being the fourth dimension, measuring the smallest change to 1/1000 mm every time you visit.
You will be shown your 3D images and we will explain the results of the different scans with you.
After your eye examination, should you require vision correction we offer a wide range of spectacles, contact lenses and sunglasses to suit your personal style and budget.
“We are able to measure the smallest change …and that changes everything.”
Use this checklist to be sure that your optometrist offers the Spectralis 4D HD Eye Health Check:
The eye examination is non-contact
The instrument produces 3-dimensional images, allowing your optometrist to more easily identify eye disease
The instrument’s tracking system replaces the scan in exactly the same place at every visit, giving a true 4D view of change over time
There is no bright flash or puff of air
The optometrist owns a SPECTRALIS imaging platform and displays the authorised SPECTRALIS 4D HD Eye Health Check logo
What is OCT?
An Optical Computer Tomography is a device that acquires detailed images and scans of the structure of the eye. Our Heidelberg Spectralis OCT contains different enhanced ‘modules’ and lenses which we are constantly upgrading to provide the best and most comprehensive eye health exam. OCT scans are non-invasive and safe for all ages to repeat regularly.
Why OCT?
Not all OCTs are the same… Some high-street OCT ‘scans’ are limited to just take basic flat images. These, although fine for some, are not able to investigate critical structural changes within the different layers of cells and therefore can miss potentially serious underlying problems.
OCT systems are designed to be modular; upgradable, but only a handful of highly specialised practices invest in this powerful diagnostic and monitoring tool. Technology such as TruTrack allows us to repeat scans in the exact same location down to the micron (1/100th mm), this means we can detect the smallest of changes over time, offering you peace of mind or referring you for the right treatment at the right time.
Why choose John Rose for your OCT?
John Rose was the first optometrist to introduce Spectralis OCT into the UK market, and is highly recognised and regarded as a pioneer within the optometric community. Driven by passion to offer the best possible service and eye care available in the country.
Here are some of the scans that we consider routine within our highly-specialised practice, some of which can normally only be undertaken in a specialist hospital environment:*
Scans:
- Retinal Scans: Located by operator to investigate any suspicious structure seen in widefield imaging. Come in different densities, sizes and angles.
- JRret: Custom high-density scan of the macula to assess drusen/AMD progress.
- Retina Line slice scan: Single line scan that investigates fovea/macular condition, penetrates down layers of the retina including Bruches membrane .
- *OCTA: Angiography used to map the blood vessels of the retina. Which usually requires a hospital visit.
- Glaucoma module scans: Utilises TruTrack
- Posterior pole scans: Series of slices that provide overview of retina, vertical and horizontal (N-site, separate scan). Also allows for macular ganglion cell review.
- Optic nerve RNFL (retinal nerve fibre layer): Circular scan of tissue around optic nerve to assess glaucoma (RNFL-N for altered view of optic neuropathies such as MS).
- Glaucoma radial scans: Slices across optic nerve (N scan for altered view).
- ONH (optic nerve head): Scans horizontal across optic nerve.
- Imaging:
- Widefield: Wide angle lens and image system for the back of the eye for general inspection.
- Infra-red: Images of retina (macula, fundus) and optic nerve
- Multicolour: Uses 3 laser types to provide diagnostic images for conditions such as Geographic atrophy, drusen, diabetic retinopathy and vitreopapillary adhesion. Can be used in conjunction with Widefield lens (dilation required).
- Anterior segment: Allows imaging of cornea, sclera and anterior chambers of the eye.
- Blue Peak Autofluorescence: Uses certain wavelengths of blue light to highlight active disease within the retina as well as morphological alterations.
