WebHow Does OCT Work? OCT utilizes technology that is similar to CAT scans of internal organs, using a scattering of light to rapidly scan the eye to create an accurate cross-section. OCT also measures the thickness of retinal nerve fiber layers to diagnose glaucoma and other diseases of the optic nerve. Why OCT is Safe? WebHow does OCT work? OCT uses light from the red end of the spectrum (near infra-red). As a result, it can penetrate the light-scattering tissues of the eye (and other organs). Transparent tissues, like the cornea and lens of the eye, allow light to pass through. But retina and skin tissue are semi-translucent. This means only some light can ... truss bridge design softwareWebOptical coherence tomography ( OCT) is an imaging technique that uses low-coherence light to capture micrometer -resolution, two- and three-dimensional images from within optical … philippine women university 1919
