title: [Transnasal endoscopic optic nerve decompression for traumatic optic neuropathy: analysis of 155 cases].
abstract: OBJECTIVE
  To explore the outcome of transnasal endoscopic optic nerve decompression (TEOND) for traumatic optic neuropathy (TON).
  
  
  METHODS
  The clinical data of 155 consecutive patients with TON treated with TEOND after failure of mega-dose steroid therapy were retrospectively analyzed, their outcomes were summarized after follow-up, and then Logistic regression was used to analyze the prognosis-related information to explore the factors influencing prognosis.
  
  
  RESULTS
  Patients were followed up for 3 - 60 months. The total effective rate of the 155 patients was 44.5%. The effective rate of the patients with light perception or better vision was 87.5%, much higher than that of the patients without light perception (29.6%). Eyesight was improved, mostly occurring 1 - 5 days after operation and lasting for 1 - 3 months, in 69 patients. Residual vision degree after trauma (OR = 0.04) and the interval between injury and surgery (OR = 4.62) were significant prognostic factors of the general effect (P < 0.01), and the gradual or immediate visual loss history (OR = 0.22) and the interval between injury and surgery (OR = 6.34) were significant to the outcomes of the patients with no light perception (P < 0.05). Sex, age, duration of coma after trauma, pre- and post-operative duration of steroid treatment, operators, fracture site of optic canal, and nerve sheath incision were not correlated to the outcomes of patients (all P > 0.05). Intraoperative cerebrospinal fluid rhinorrhea and postoperative transient visual loss occurred in one and the other two cases, respectively, but these conditions were resolved successfully.
  
  
  CONCLUSIONS
  TEOND is effective and safe for TON patients, but the visual outcome is poor for the immediate blindness cases. The surgery is indicated for the patients with some residual vision or with a gradual visual loss and is suggested to perform early within seven days after injury.
