What is OCT (ocular coherence tomography)?
The ‘Rolls Royce’ of ocular coherence tomography (OCT) takes the investigation of your eye a step deeper than the surface of the macula, optic nerve and retina. OCT technology shows what is happening beneath the surface of these structures, capturing a series of cross-sectional images and measuring the thickness of various tissues. NASA currently uses this technology on the space station to understand why astronaut’s vision changes in space.
