Optical Coherence Tomography, or ‘OCT’, is a technique for imaging the thin tissues of the retina by measuring reflections off the retinal surface. OCT works much like ultrasound, but with light. It is a non-evasive, diagnostic procedure that allows for the direct, instant, cross-sectional evaluation of the retina with a resolution of up to 10 microns! It has revolutionized the way we diagnose and manage eye diseases. It allows for an earlier, more sensitive diagnosis. It also allows for the monitoring of current diseases on the microscopic level. OCT has been shown to be clinically useful for imaging selected macular and optic nerve diseases including macular holes, macular edema, age-related macular degeneration, central serous chorioretinopathy, epiretinal membranes, retinal inflammatory diseases and others. It is currently the accepted standard of care for diagnosing, managing and treating patients with glaucoma and macular degeneration. It is also questionably essential in managing the countless diabetics that walk through our doors every day. Utilizing the OCT in any optometric setting can significantly expand the scope of practice and offer each and every patient the highest standard of care available today!
