Visual loss from orbital compression and stretching of the optic nerve is an infrequent but well-recognized cause of dysthyroid optic neuropathy, occurring in less than 5% of thyroid eye disease cases. Another important but less recognized cause of vision loss due to thyroid-associated optic neuropathy is protracted stretching of the optic nerve. Of the reported cases of compression and stretch optic neuropathy, none have documented the rate of vision loss due to continuous stretching of the optic nerve.
眼眶对视神经的压迫和牵拉导致的视力丧失是甲状腺功能异常性视神经病变中一种少见但已被充分认识的病因，在不到5%的甲状腺眼病病例中出现。甲状腺相关性视神经病变导致视力丧失的另一个重要但较少被认识到的原因是视神经的长期牵拉。在已报道的压迫性和牵拉性视神经病变病例中，尚无文献记录因视神经持续牵拉导致的视力丧失发生率。
