Abstract：Objective To explore the effect of optic canal decompression via frontolateral approach for blind patients with traumatic optic neuropathy.Methods Clinical data of 13 patients (14 affected eyes) with traumatic optic neuropathy were analyzed retrospectively.The preoperative visual acuity was in no light perception in all the patients,who were treated by optic canal decompression via frontolateral approach and regularly followed up after the operation.The visual acuity increase of 2 level and above was considered as effective,increase of 1 level as meliorative and no change as invalid.Results Recovery of visual acuity within 1 week after the operation:front index was achieved in 3 eyes,front thumb in 1,light perception in 2 and no light perception in 8.Recovery of visual acuity within 1 month after the operation:front identification was achieved in 2 eyes,front index in 4,front thumb in 1,light perception in 1 and no light perception in 6.The effective surgery was obtained in 7 eyes and meliorative in 1 according to the long-term vision,and all surgeries were completed within 9 d after injury.The invalid surgery was seen in 6 eyes,2 of which underwent surgery within 9 d after injury and 4 over 9 d after injury.Conclusion Optic canal decompression via frontolateral approach is an effective method for blind patients with traumatic optic neuropathy,and the operation should be performed as soon as possible.
