FAQs

Optical Coherence Tomography (OCT) is a recently designed 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 regimes.
An OCT scan is very quick to perform and it is completely painless and non-invasive. Results are available instantaneously and it is a great way for patients to gain a better understanding of their eye condition.
