Optical Coherence Tomography

OCT is a noncontact, noninvasive imaging technique used to obtain high resolution cross-sectional images of the retina. It is analogous to ultrasound B-scan imaging except that coherent light rather than sound waves is used in order to obtain a much higher longitudinal resolution of approximately 10µm in the retina.

It has been shown to be clinically useful for imaging selected macular diseases including macular holes, macular edema, age-related macular degeneration, central serous chorioretinopathy, epiretinal membranes, schisis cavities associated with optic disc pits, and retinal inflammatory diseases. In addition, OCT has the capability of measuring the retinal nerve fiber layer thickness in glaucoma and other diseases of the optic nerve.
