Optical Coherence Tomography

Optical Coherence Tomography (OCT) is an imaging test that allows for detailed visualization of the different layers of the retina and the optic nerve. It helps physicians diagnose and monitor various diseases affecting the eye such as age-related macular degeneration and glaucoma.

The OCT image is captured by directing focused beams of light into the eye for a few seconds. These beams of light are reflected out of the eye and are processed to give very detailed cross-sectional images of the different structures of the eye. This test is non-invasive and takes about 15 minutes from start to finish. Eyes are usually dilated for this test.
