LP97035-7   OCT
Optical coherence tomography (OCT) is a non-invasive imaging technique that provides an in vivo, cross-sectional view of the retina. There are 6 retinal layers viewable with OCT: the nerve fiber layer (NFL), the inner plexiform layer and ganglion cell layer (IPL+GCL), the inner nuclear layer (INL), the outer plexiform layer (OPL), the outer nuclear layer and photoreceptor inner segments (ONL+PIS), and photoreceptor outer segments (POS). OCT uses low-coherence interferometry to provide very accurate cross-sectional images. Two forms of OCT are time domain and spectral domain. Spectral domain has replaced the former because of its speed (20,000+ scans per second to avoid motion artifacts) and high resolution, and it can both visualize and measure the thickness of the retinal pigment epithelium and the nerve fiber layer adjacent to the optic disc.
