WebAbstract—The Henle’s fiber layer (HFL) in the retina carries valuable information on the macular condition of an eye. How-ever, in the common practice, this layer is not separately seg-mented but rather included in the outer nuclear layer since it is difficult to perceive HFL contours on standard optical coherence tomography (OCT) imaging.

WebHenle fiber layer (HFL) in vivo. Here, we used D-OCT to characterize the HFL and outer nuclear layer (ONL) in albinism and examine the relationship between true foveal ONL and peak cone density. METHODS. Horizontal D-OCT B-scans were acquired, registered, and averaged for 12 subjects with oculocutaneous albinism and 26 control subjects.
