What is OCT?
Optical coherence tomography uses light waves to capture detailed, layer-by-layer images of the retina and optic nerve, similar to a CT scan but for the back of the eye. It is completely painless and takes only a few minutes.
Why it is so valuable
OCT detects subtle changes in macular and optic nerve thickness, making it indispensable for diagnosing and monitoring macular degeneration, diabetic macular oedema, glaucoma and many other conditions.
