PURPOSE
To describe the appearance of concentric, fingerprint-like waves within the Henle fiber layer (HFL) using en face optical coherence tomography in patients with tractional pathologies of the retina.
METHODS
Retrospective analysis of six eyes of six patients imaged by optical coherence tomography with volumetric slabs positioned at the level of the HFL.
RESULTS
Optical coherence tomography data from six patients with tractional vitreoretinal pathology were reviewed. Concentric, fingerprint-like microwaves were visualized through en face optical coherence tomography in all six study eyes at the level of the HFL. This finding resembled the finding of HFL waves previously noted histopathologically from force exerted on this layer.
CONCLUSION
In retinal pathologies in which specific physical forces act on the retina, volumetric optical coherence tomography may permit visualization of en face concentric, fingerprint-like hyperreflective rings within the HFL. This "fingerprint sign" may represent a biomechanical consequence of traction on the retina and allow clinical decision making based on improved recognition of the existence of such traction.
目的
通过对视网膜牵引性病变患者的共焦光学相干断层扫描（OCT），描述 Henle 纤维层（HFL）内出现的同心、指纹状波。
方法
对 6 例患者的 6 只眼进行 OCT 体层扫描，扫描层面位于 HFL 水平。
结果
对 6 例患有牵引性玻璃体视网膜病变患者的 OCT 数据进行了回顾性分析。在 HFL 水平，所有 6 只研究眼的共焦 OCT 均可见同心、指纹状微波。这一发现与之前对该层施加特定物理力时组织病理学发现的 HFL 波相似。
结论
在特定物理力作用于视网膜的视网膜病变中，OCT 体层扫描可能允许在 HFL 内可视化共焦同心、指纹状高反射环。这种“指纹征”可能代表了对视网膜的牵引的生物力学后果，并允许基于对这种牵引存在的更好识别来进行临床决策。
