To confirm the structure of the fiber connection between Whitnall's ligament and the superior wall of the orbit, ten orbits from five Japanese cadavers were examined by magnetic resonance imaging (MRI) and dissection. MRI showed a well-circumscribed low-intensity signal at the fiber connection. Pre-aponeurotic fat was prominent and the fibers originating from Whitnall's ligament were fused at the lower face of the capsule of the pre-aponeurotic fat in four cadavers. Fibers originating from the upper face of the fat were attached to the superior periorbit (minimum width: 15 mm). The fifth cadaver had very little pre-aponeurotic fat and few fibers. These anatomic differences may be within the normal range of variation. The fibers may support Whitnall's ligament and may help to retract pre-aponeurotic fat during levator muscle contraction as the eye opens.
为了确认惠特纳尔韧带与眶上壁之间纤维连接的结构，对来自五具日本尸体的十个眼眶进行了磁共振成像（MRI）检查和解剖。MRI显示纤维连接部位有边界清晰的低强度信号。在四具尸体中，腱膜前脂肪突出，起源于惠特纳尔韧带的纤维在腱膜前脂肪囊的下表面融合。起源于脂肪上表面的纤维附着于眶上缘（最小宽度：15毫米）。第五具尸体的腱膜前脂肪很少，纤维也很少。这些解剖差异可能在正常变异范围内。这些纤维可能支撑惠特纳尔韧带，并可能在睁眼时提上睑肌收缩过程中帮助回缩腱膜前脂肪。
