3D OCT DIGITAL RETINAL SCANS AND PHOTOGRAPHY

3D OCT Line Scan of an eyeWe are one of the first practices in the area to have invested in OCT technology and offer a unique service to patients in the area to offer patients an outstanding level of care at our Spalding practice.

We have always believed in the need to stay abreast of all the latest developments in technology and believe that it is through clinical differentiation that patients visit our practice.

OCT technology is the next generation in imaging the internal structures of the eye. The unique way in which the image is formed means that for the first time it is possible to see below the surface of the retina and view the microscopic layers beneath. This is of profound importance in determining the precise diagnosis of visual problems and in helping us guide patients on the treatment options possible.

3D Scan of an eyeEveryone would benefit from OCT scans, we can now see to a much higher resolution including changes to the retinal thickness (down to the nearest micron), which can be the earliest sign of eye problems.

The scanning procedure is painless and is similar to having a photograph taken, but with the camera positioned close to the eye. Nothing touches the eye and there is no discomfort during the scan.

We do 2 scans for each eye:

  1. Macula scan – to show for example early stages of Macular Degeneration, macula holes, pre-retinal membranes, or fluid on the macula
  2. Optic nerve scan – to analyse the thickness of the optic nerve fibres for Glaucoma.

Basically our Topcon OCT not only takes better more detailed retinal photographs by using a Nikon digital SLR camera, but takes 128 individual cross-section scans of the retina at the back of the eye. These scans are like viewing a biopsy of the retina on a high powered microscope without even touching the eye. Looking at the scans below, the average thickness of the retina in cross-section is about ½ mm, but this does vary considerably from person to person. These scans can also be put together to produce a 3D image of the back of the eye, which is a very powerful tool to show small detail and changes that could cause future problems.

MACULAR SCANS CAN ALSO DETECT THE VERY EARLIEST CHANGES IN WET AMD AND CONSEQUENTLY EARLY TREATMENT CAN HELP RETAIN EYESIGHT.

It is with this technology and Andrew Molsom’s accreditation that we are able to offer the Primary Eye Care clinics to see patients in the community.
