The occurrence of upper lid ptosis in 66 patients in the anophthalmic state was 18 percent, despite an adequate prosthesis. The commonly cited causes for this entity do not hold up under examination. A detailed review of the anatomy of the levator mechanism and of the anatomy of an enucleation suggests that the etiology is really based on the production of a mechanical imbalance in the levator apparatus. Suggestions for management and for the timing of the correction (in relation to other surgical procedures) are made.
在66例无眼球状态的患者中，尽管使用了合适的义眼，上睑下垂的发生率仍为18%。对此情况通常所列举的病因经检查并不成立。对提上睑肌机制的解剖结构以及眼球摘除术的解剖结构进行详细回顾后发现，病因实际上是提上睑肌装置中产生了机械性失衡。文中还给出了治疗建议以及（与其他外科手术相关的）矫正时机的建议。
