Colour Doppler imaging (CDI) is an ultrasonic method for qualitatively and quantitatively assessing blood flow. Recently this technique has been adapted for investigation of the orbital, optic nerve and ocular vasculature. We discuss the history, principles and methodology of this examination technique for ophthalmology. Also described are normal haemodynamic characteristics as well as the findings in common pathological states involving derangements of orbital blood flow. Although CDI is relatively new to ophthalmology it has already proved to be of benefit in conditions with altered orbital, ocular and optic nerve blood flow. In the future it is expected that the indications for the applications of CDI will become more clearly defined and that orbital CDI will be more widely available and utilised, especially in the investigation of vascular diseases of the orbit, optic nerve and retina.
彩色多普勒成像（CDI）是一种用于定性和定量评估血流的超声方法。最近，这项技术已被应用于眼眶、视神经和眼部血管系统的研究。我们讨论了这种眼科检查技术的历史、原理和方法。还描述了正常血流动力学特征以及涉及眼眶血流紊乱的常见病理状态下的表现。尽管CDI在眼科领域相对较新，但它已被证明在眼眶、眼部和视神经血流改变的情况下是有益的。未来，预计CDI的应用指征将更加明确，眼眶CDI将更广泛地获得和应用，特别是在眼眶、视神经和视网膜血管疾病的研究中。
