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.
