重视光相干断层扫描技术在神经眼科中的应用

Focusing on the application of optical coherence tomography in the field of neuro-ophthalmology

【摘要】光相干断层扫描技术以能够观察发现轻微视盘水肿、光感受器内外节连接层改变，测量视盘周围平均视网膜神经纤维层厚度、视网膜厚度、黄斑容积，检测轴索丢失、黄斑区神经节细胞复合层损害等独特优势，在青光眼和非青光眼性视神经病变、视神经疾病和黄斑疾病、外层和内层视网膜病变的诊断与鉴别诊断，评价神经眼科疾病疗效、随访观察及评估疾病预后以及神经眼科疾病发病机制研究等方面均表现出重要的应用价值和广泛的应用前景。值得广大神经眼科医生深入了解、重视和应用。

Optical coherence tomography （OCT） can depict mild papilledema and slight changes in the internal segment and external segment; measure thickness of the retinal nerve fiber layer, retinal thickness and macular volume; detect missing axons and damage to the macular ganglion cell complex. Thus, OCT has important application values and widespread prospects in diagnosis and differential diagnosis of glaucoma and non-glaucoma optic neuropathy, optic nerve diseases and macular diseases, outer and inner retinopathy as well as evaluation of curative effects, follow-up observation, prognosis and mechanisms in neuro- ophthalmological diseases. Neuro-ophthalmologists should pay more attention to the exploration and application of OCT in the field of neuro-ophthalmology.
