摘要
光学相干断层成像(optical coherence tomography,OCT)技术已经成为眼科良好的影像学检查工具。OCT所带来的前所未有的深度分辨率能够对眼前段到后段的组织结构提供很有价值的参考信息。偏振光学相干断层成像技术(polarization-sensitive optical coherence tomography,PS-OCT)在OCT技术的基础上,利用偏振光技术能获得组织层面更多有用的信息。眼部的一些组织,像角膜、视神经纤维层、视网膜色素上皮层能够改变探测光的偏振状态,从而在PS-OCT图像上产生特殊的组织对比,达到观察目的。本文主要就PS-OCT在眼科学方面的发展和现状作一简要介绍,并对其在眼科疾病中的临床应用进行阐述。
Optical coherence tomography( OCT) has become a good imaging tool for ophthalmology. The unprecedented depth resolution brought by OCT can provide valuable reference information for the organizational structure from anterior segment to posterior segment. Polarization sensitive optical coherence tomography( PS-OCT) based on OCT technique,more useful information can be obtained by using polarized light technology. Some tissues of the eye,such as cornea,optic nerve fiber layer and retinal pigment epithelium,which can change the polarization state of probe light,and thus produce special tissue contrast on PS OCT images to achieve the purpose of observation. This article mainly introduces the development and present situation of PS-OC Tin ophthalmology and its clinical application in ophthalmology.
