摘　　要：视乳头水肿是由于颅内压升高导致视盘神经纤维轴浆流障碍,视盘水肿、抬高,并向前隆起。假性视乳头水肿多为视盘形态异常,如视盘玻璃疣、视盘倾斜等,眼底照相可见视盘边界模糊。临床上难以鉴别视乳头水肿和假性视乳头水肿,谱域光学相干断层扫描(SD-OCT)提供了一种无创、易获取、高分辨率的成像技术,通过测量视盘周围神经纤维层厚度、视盘体积和总视网膜厚度等定量指标或观察视盘周围形状和移位、视网膜皱褶等定性指标,可提高诊断准确性。本文主要讨论SD-OCT在鉴别视乳头水肿和假性视乳头水肿中的应用价值。Papilledema is due to the increase of intracranial pressure,which leads to the disorder of axoplasmic flow of nerve fibers,optic disc edema and elevation.Pseudopapilledema is mostly due to congenital morphological abnormality of the optic disc,such as optic disc drusen,optic disc tilt and so on.Fundus photography shows unclear optic disc boundaries.It is difficult to distinguish papilledema from pseudopapilledema.Spectral-domain optical coherence tomography(SD-OCT)provides a noninvasive and easy imaging method to obtain high-resolution images that can improve diagnostic accuracy through quantitative indexes such as peripheral nerve fiber layer thickness,optic disc volume and total retinal thickness,or qualitative index such as shape and displacement around the optic disc,retinal fold,and so on.This paper mainly discusses the application value of SD-OCT in differentiating papilledema from pseudopapilledema.
