Optical coherence tomography (OCT) is a rapid non-contact method that allows in vivo imaging of the retina, optic nerve head and retinal nerve fibre layer (RNFL). Since its introduction in Ophthalmology approximately a decade ago, the use of this technology has disseminated into the clinical practice. OCT has proven to be a useful ancillary tool for assessing retinal diseases because of its capability to provide cross-sectional images of the retina, and also to perform quantitative analysis of retinal morphology. In glaucoma, the OCT represents one of the methods capable of documenting and analysing optic disc and RNFL morphology in attempt to diagnose and monitor glaucomatous optic neuropathy. Recently, the spectral domain OCT became available, a new technique that allowed major improvements particularly regarding image acquisition speed and image resolution. Future studies will address how these major technological advances will impact the use of the OCT in research and clinical practice.
光学相干断层扫描（OCT）是一种快速的非接触式方法，可对视网膜、视神经乳头和视网膜神经纤维层（RNFL）进行体内成像。自大约十年前该技术引入眼科以来，其应用已在临床实践中得到普及。由于OCT能够提供视网膜的横断面图像，并能对视网膜形态进行定量分析，它已被证明是评估视网膜疾病的一种有用的辅助工具。在青光眼方面，OCT是能够记录和分析视盘及RNFL形态以试图诊断和监测青光眼性视神经病变的方法之一。最近，谱域OCT问世，这项新技术尤其在图像采集速度和图像分辨率方面有了重大改进。未来的研究将探讨这些重大技术进步将如何影响OCT在研究和临床实践中的应用。
