タイトルまたは説明

optical Coherence Tomography (OCT) is a new, noninvasive, and noncontact, imaging technology which can image retinal structures in vivo with a resolution of 5 to 8 microns. Cross-section images of the retina are produced using the optical backscattering of light in a fashion analogous to B-scan ultrasonography and confocal microscopy. Cross-sectional images of the retina are revolutionizing the early detection and treatment, and greatly ensure the quality of patient management.

Applications
In vivo, cross-sectional images and quantitative analysis of retinal features to optimize the diagnosis and the monitoring of retinal disease and enhance pre- and post-therapy assessment.

High-quality images and accurate measurement of RNFL and the optic nerve head to assist in the detection and management of glaucoma.

Cross-sectional images are valuable for clinical evaluation of macular holes, macular edema and other retinal pathologies.

Precise location of pathology to expand diagnostic confidence and therapeutic precision.

OCT is a kind of non-invasive bio-tissue imaging with ultra-high resolution. Its theory comes from the different reflectivity of the various tissue structures. In the ophthalmological OCT imaging, different colors stand for different reflective intensity. Usually red represents the high value, and black and yellow represent low and middle, respectively. The inner structure image helps doctor to quantitatively analyse the thickness of the center fovea. Moreover, a database is built to make contrast among a variety of people. According to OCT images, some potential disease which is contained in the inner structure could be clearly found, that’s the remarkable advantage for OCT imaging technology.
