眼肌麻痹可分为部分性或全眼性两种,部分性眼肌麻痹又分为眼内肌(即虹膜、睫状体肌)麻痹(瞳孔散大、无反应)与眼外肌麻痹(常同时合并上睑下垂)两种。全眼肌麻痹系眼球全部运动神经麻痹,如为单侧,病变可能在眶内、眶上裂或海绵窦。其发病原因很多,如外伤,鼻窦炎、原发性眼眶肿瘤、淋巴瘤、癌、结节性动脉周围炎、梅毒性骨膜炎、海绵窦栓塞、动脉瘤、颈内动脉海绵窦瘘、糖尿病与眼肌麻痹性偏头痛等。 Part of the ophthalmoplegia is divided into paralysis of intraocular muscles (ie, iris and ciliary body muscle) (mydriasis, no response) and extraocular muscle paralysis Often combined with ptosis) both. The whole eye paralysis Department of eye all motor nerve paralysis, such as unilateral, the lesion may be in the orbit, supraorbital fissure or cavernous sinus. The incidence of many causes, such as trauma, sinusitis, primary orbital tumors, lymphoma, cancer, nodular periarteritis, syphilitic periostitis, cavernous sinus embolism, aneurysm, carotid cavernous fistula, diabetes and Ophthalmoplegia migraine and so on.
