Eye Scan Detects Diseases Years Before Symptoms Eye scan technology has been touted as a revolutionary non invasive diagnostic tool that can detect diseases years before symptoms appear.
At its core, an eye scan uses optical coherence tomography (OCT) to create high resolution images of the retina and other ocular tissues.
This is achieved by directing a low coherence laser into the eye, which scatters off the retinal tissue and returns to the OCT device as reflected light.
