We reported 42 cases of indirect optic nerve trauma in craniofaeial injuries. Mydriasis in affected eyes was found in 30 cases with absence or diminish of direct pupillary reflex but presence of indirect pupillary reflex. Imaging examination revealed optic canal fracture in 24 eases. Seven of 9 patients in whom the diagnosis of optic trauma was comfirmed received operation of optic nerve decompression from cranial and superior orbital wall approach within 10 days following injuries ,resulting in improvement of visual loss. While the other 2 patients operated on 15 days after trauma,obtained no relieve in their visual impairemenl. And 7 of 21 presumed cases of indirect optic trauma in this series treated with steroids became blind. We suggested that pupillary examination,imaging analysis,as well as early diagnosis and operation were essential to diagnosis and management of indirect optic trauma complicating craniofacial injuries. （Chin J Ocul Fundus Dis,1994,10:210-212）
