WebMar 31, 2024 · How Does OCT Work? Experts draw parallels between OCT and ultrasounds, but OCT uses light rather than sound. The non-invasive test sends light beams into the eyes, which are then bounced back to the sensors. Just like an ultrasound uses sound echoes to visualize tissues and organs in your body, OCT images tell the machine the size and … 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?
