Before the invention of magnetic resonance imaging (MRI), it was impossible to observe an architectural deformation of the eyelid because of its movement. The authors observed MRI films of 15 eyelids in both closed and opened positions and obtained new information on the architecture of the upper eyelid and also the mechanism of single and double eyelids, and sunken eye formation. (1) Orbital fat is transposed when the lid moves. If the fat can not return into the orbit when the lid opens, it droops and interferes with the fold formation of the lid. (2) The thickness of the eyelid skin is associated with double-eyelid formation. The skin fold is observed at the junction between thick skin with subcutaneous fat and thin skin without it. (3) We could not confirm Doxanas and Anderson's assertion that septal insertion was lower in Orientals. However, we observed pretarsally drooped or herniated orbital fat in many slit-eye Orientals. (4) There are three angles at the tarso-levato-aponeurotic line: one at the junction with transverse ligament, one at the point of septal insertion, and another at the aponeurotic terminal on the tarsus.
在磁共振成像（MRI）发明之前，由于眼睑的活动，不可能观察到其结构变形。作者观察了15只眼睑在闭合和张开位置的MRI影片，获得了关于上睑结构以及单眼皮和双眼皮形成机制、眼窝凹陷形成机制的新信息。（1）眼睑移动时眶脂肪会移位。如果眼睑张开时脂肪不能回到眼眶，就会下垂并干扰眼睑褶皱的形成。（2）眼睑皮肤厚度与双眼皮形成有关。在有皮下脂肪的厚皮肤与无皮下脂肪的薄皮肤交界处可观察到皮肤褶皱。（3）我们无法证实多克萨纳斯和安德森关于东方人眶隔附着较低的论断。然而，我们在许多眯缝眼的东方人身上观察到睑板前眶脂肪下垂或疝出。（4）睑板 - 提上睑肌腱膜线有三个角度：一个在与横韧带交界处，一个在眶隔附着点，另一个在睑板上的腱膜末端。
