Optical Coherence Tomography (OCT)

Optical Coherence Tomography (OCT) is a new technology that allows almost instant imaging of the retina at the back of the eye. Thousands of images are collected in a few seconds whilst the patient looks at a flashing light. It is quite painless. These images are assembled into one detailed image which can then be analysed. The Clinic has just purchased the latest version of this technology which gives faster, higher definition images.

The two major uses are for glaucoma and macular degeneration.

Very early changes can be detected in glaucoma, well before any visual problem occurs. This means early treatment can be started and reduces the risk of there ever being a visual problem. In combination with computerised visual field testing, glaucoma can be easily monitored and treatment adjusted as required.

Macular degeneration can occur as either the dry form or the wet form. In the wet form, abnormal blood vessels grow under the retina and leak fluid. If nothing is done, these vessels can bleed and scar causing permanent damage to the vision. OCT can detect the earliest part of this process, and, now with new drugs, there is an excellent chance that the process can be halted or even reversed.
