Analysis of Prognostic Factors for the Indirect Traumatic Optic Neuropathy Underwent Endoscopic Transnasal Optic Canal Decompression.
2020
OBJECTIVE: This study aimed to investigate the clinical outcomes of endoscopic transnasal optic canal decompression (ETOCD) for patients with indirect traumatic optic neuropathy (TON) and identify the relevant prognostic factors. METHODS: Seventy-two indirect TON patients who underwent ETOCD surgery from August 2017 to May 2019 were analyzed retrospectively. The paired t-test was used to compare the visual acuity (VA) before and after ETOCD, and multiple linear regression analysis was used to distinguish the potential prognostic factors. RESULTS: Among the patients analyzed, postoperative VA (-2.87 +/- 0.19) was significantly higher than the preoperative VA (-3.92 +/- 0.13) (P 0.05). CONCLUSIONS: ETOCD surgery could salvage VA impairment in patients with indirect TON. A better initial VA indicates better final VA outcomes after surgery. Additionally, shorter time to surgery implies better VA prognosis and higher IDVA.
