随着近年来光学相干断层扫描(optical coherence tomography,OCT)技术的发展,视网膜细微结构更多的细节可被观察.在视网膜外层的OCT成像中有四条高反射线,即外界膜(externallimiting membrane,ELM)、内节/外节交界区(inner segment/outer segment junction,IS/OS)、锥细胞外节末端(cone outer segment tips,COST)和视网膜色素上皮(retinal pigment epithelium,RPE),这些高反射线的完整性与各种视网膜疾病的视力等功能相关,能够提示疾病的预后.本文就OCT对视网膜外层结构显像及其与常见视网膜疾病治疗后视功能恢复的关系进行综述.

In recent years,the fast-developing optical coherence tomography (OCT) technology has provided us more details of the outer retina microstructure.The four hyperreflective lines in OCT images (external limiting membrane,ELM; inner segment/outer segment junction,IS/OS; cone outer segment tips,COST; retinal pigment epithelium,RPE) are associated with visual acuity and function in different retinal diseases,and are able to predict prognosis and clinical outcomes of retinal diseases.In the present review,the emerging knowledge about the microstructures of the outer retina and its relationship with visual function in different retinopathies will be discussed.
