Optical Coherence Tomography (OCT)

Optical coherence tomography (OCT) is a coherent imaging technique, based on interferometry, where the light "echoes" of biological tissue are detected and displayed. OCT is a noncontact, noninvasive imaging technique which we use to obtain high resolution cross-sectional images of the retina. OCT could be compared to ultrasound imaging except that light waves rather than sound waves are used in order to obtain a much higher image resolution of the retina. OCT has been shown to be clinically useful for imaging many macular disorders including macular holes, macular edema, age-related macular degeneration, 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.

Early detection of any change is very important for successful prevention and treatment. Periodic tests are integral and necessary for proper visual health.
