摘要:

方向相干光断层扫描成像(directional optical coherence tomography,D\|OCT)是一种通过改变扫描光束在瞳孔的入射位置,得到视网膜同一部位不同反射强度横截面图像的方法,可清晰地显示Henle纤维层(Henle′s fiber layer ,HFL)与外核层(outer nuclear layer,ONL)的边界,有助于准确观察并分析HFL与ONL的形态及厚度改变,对于影响HFL及ONL的疾病,如黄斑囊样水肿、年龄相关性黄斑变性等的研究有重要的临床指导意义。

Abstract:

Directional optical coherence tomography (D\|OCT) is a method of obtaining a cross\|sectional image of different reflection intensity at the same part of the retina by changing the incident position of the scanning beam at the pupil. The boundary between Henle′s fiber layer(HFL)and outer nuclear layer(ONL)can be clearly displayed, which is helpful to accurately observe and analyze the morphological and thickness changes of HFL and ONL. It has important clinical significance for the study of diseases affecting HFL and ONL, such as cystoid macular edema (CME), age\|related macular degeneration (AMD), etc.
