Optical Coherence Tomography (OCT)
Better known as an OCT, Optical Coherence Tomography uses light waves to obtain high-resolution pictures of the structural layers of the back of the eye. Being one of the latest advancements in imaging technology, OCTs provide color-coded, cross-sectional images of the retina, important in the early detection and treatment of eye disease, including age-related macular degeneration, retinal detachment, and diabetic retinopathy.
The OCT is a quick, noninvasive test. After your pupils are dilated, you will be asked to put your chin on the OCT’s chinrest and forehead against the support strap, hold steady, and focus on a target light while the technician takes images. The procedure does not typically involve pain.
