Optical Coherence Tomography

Change Text Size A A A

Optical Coherence Tomography (OCT) is a non-contact, noninvasive, advanced imaging technique used to obtain high-resolution cross-sectional images of the retina.

OCT is often used to diagnose selected macular diseases such as macular holes, macular edema, age-related macular degeneration, central serous retinopathy, epiretinal membranes, and retinal inflammatory diseases. 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. Unlike other imaging techniques, OCT uses no radiation, sound, or radiofrequency waves. As a result, there is no risk to the patient or harmful side-effects. OCT also measures the thickness of retinal nerve fiber layers to diagnose glaucoma and other diseases of the optic nerve.

Optical Coherence Tomography is available at Illinois Retina Associates.
