is an OCT scan?
Optical Coherence Tomography (OCT) is a new imaging technique that
provides 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 eye conditions such as 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 (Avastin or Lucentis) for age-related macular
degeneration and tailoring treatment regime.
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.
