[A 212 cases analysis of treatment for traumatic optic neuropathy by nasal endoscopic opticnerve decompression]

Objective:To explore the clinical features and therapeutic efficacy of nasal endoscopic optic nerve decompression for traumatic optic neuropathy (TON)treatment.Method:Two hundred and twelve cases (217 eyes) with TON were retrospectively analyzed in our study, who were treated with nasal endoscopic optic nerve decompression in our institution from 1999 to 2016. χ ² -test was used to explore the potential prognostic factors on visual acuity.Result:All patients were followed up from 6 months to 2 years postoperatively, and the effective rate was 54.38%(118/217).In the 166 eyes with no light perception (NLP), the effective rate was 46.39% (77/166), while in the 51 eyes with light perception (LP), the effective rate was 80.39% (41/51).The therapeutic efficacy of patients with LP or above LP was better than that of NLP, and the difference was statistically significant(χ ²=18.186, P< 0.01).Moreover, the therapeutic efficacy of patients without an optic canal fracture was better than that with an optic canal fracture，and the difference had statistical significance (χ ²=10.096, P<0.01).Conclusion:The efficacy of nasal endoscopic optic nerve decompression on TON was positive, and even for the patients with NLP or a long history also should have a try.
