Optical Coherence Tomography

iFusion-PatientOptical coherence tomography (OCT) is an advanced technology used to produce cross-sectional images of the retina, the light-sensitive lining on the back of the eye where light rays focus to produce vision. These images can help with the detection and treatment of serious eye condition such as macular holes, macular swelling and optic nerve damage.

OCT uses technology that is similar to CT 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 light to produce high resolution images, rather than sound or radiofrequency waves. Dr. Cartwright can evaluate and measure each layer of the retina through this image and compare it with normal, healthy images of the retina.

The OCT exam takes about 10 to 20 minutes to perform in our office.
