Optical Coherence Tomography


Optical Coherence Tomography is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina. This laser scanning system acquires and analyzes the retina in three dimensions. It provides a high-resolution topographical map of the optic disc, which is the "head" of the optic nerve. It measures the key structures and stores them, enabling Dr. Gauerke to recognize changes that may indicate progression of glaucoma.
