OPTICAL COHERENCE TOMOGRAPHY

OPTICAL COHERENCE TOMOGRAPHY (OCT)

Optical Coherence Tomography (OCT) is an imaging technique used to provide unprecedented high-resolution and cross-sectional images of the eye. The OCT scan allows microstructures of the eye to be imaged and shows different colour-coded layers of the retina. It is particularly useful in the diagnosis and management of age-related macular degeneration, diabetic macular oedema, macular hole, epiretinal membrane, vitreo-macular traction syndrome and glaucoma. It has also become a gold standard in monitoring the efficacy of intravitreal anti-VEGF injections (Eylea, Lucentis or Avastin) for age-related macular degeneration and tailoring treatment regime.

Ultrawide-field, high-resolution OCT scanning is available at City Eye Centre using the Plex Elite OCT (Carl Zeiss) to image all layers of the retina and choroid. The ultrawide-field imaging is particularly useful in myopia, retinal masses and choroidal tumours. An OCT scan is very quick to perform and it is non-invasive and painless. Results are available instantaneously and it is an effective way for patients to gain a better understanding of their eye condition.
