Optical Coherence Tomography (OCT) 3D Eye Exams

Optical Coherence Comography camera from - https://en.wikipedia.org/wiki/File:OCT_Optical_Coherence_Comography_camera_Topcon_3D_OCT_2000.jpgOptical Coherence Tomography, or ‘OCT’, is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope. It is effectively ‘optical ultrasound’, imaging reflections from within tissue to provide cross-sectional images.

An optical beam is directed at the tissue, and a small portion of this light that reflects from sub-surface features is collected. Note that most light is not reflected but, rather, scatters off at large angles. In conventional imaging, this diffusely scattered light contributes background that obscures an image.

OCT can build up clear 3D images of thick samples by rejecting background signal while collecting light directly reflected from surfaces of interest.

Fundus Camera

A photo taken with a Fundus cameraA Fundus camera captures images of your retina, at the back of your eye, and is a quick and painless procedure.

The camera allows an improved inspection of the back of your eye than was previously possible. This imaging service is invaluable, as this will store the pictures on a computer, allowing us to compare images and look for changes with your regular check-ups.

Should a referral to a consultant ophthalmologist be required for further opinion we will also be able to send the digital image to them.

If required, this is included in your eye examination as part of our pre screening.
