Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. Here we were presented with 30 cases of sudden visual loss following blunt eye trauma seen in Kaohsiung Medical College Hospital, Taiwan from April 1994 to March 1997. We analyze the treatment style, visual acuity, elapsed time since injury and orbit computed tomography retrospectively. Among them, 21 cases received intravenous methylprednisolone treatment, 2 cases received oral prednisolone, 2 cases underwent optic canal decompression in addition to intravenous methylprednisolone and 5 cases were carefully monitored without any kind of treatment. Thirteen of the 21 cases (62%) in intravenous methylprednisolone group got visual improvement. Patients with initial vision better than light perception benefitted more from treatment than did the patients who with no light perception in medical treatment group (85% VS 20%) (p < 0.05). Thirteen of the 30 cases (53.3%) had orbit fracture and 2 of the 30 cases (6.7%) had a fracture of the optic canal. These two cases also received optic canal decompression surgery in addition to intravenous steroid treatment but the prognosis was poor. In conclusion, intravenous methylprednisolone does offer help in traumatic optic neuropathy. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome. In this article, we also compare our results with other series in the literature and found that the value of different treatment in traumatic optic neuropathy still needs to be prospectively judged in the future.
外伤性视神经病变是真正的眼科急症之一,目前尚无经证实有效的外伤性视神经病变治疗方法。本文报告了1994年4月至1997年3月在台湾高雄医学院附设医院就诊的30例钝性眼外伤后突然视力丧失的病例。我们回顾性分析了治疗方式、视力、受伤后的时间以及眼眶计算机断层扫描结果。其中,21例接受了静脉注射甲基强的松龙治疗,2例接受口服强的松龙治疗,2例在静脉注射甲基强的松龙的基础上接受了视神经管减压术,5例在密切观察下未接受任何治疗。静脉注射甲基强的松龙组的21例患者中,有13例(62%)视力得到改善。在治疗组中,初始视力优于光感的患者比无光感的患者从治疗中获益更多(85%对20%)(p<0.05)。30例患者中有13例(53.3%)发生眼眶骨折,30例中有2例(6.7%)发生视神经管骨折。这2例患者除接受静脉类固醇治疗外,还接受了视神经管减压手术,但预后较差。总之,静脉注射甲基强的松龙对外伤性视神经病变确实有帮助。初始视力是否优于光感是影响预后的关键危险因素。在本文中,我们还将我们的结果与文献中的其他系列进行了比较,发现外伤性视神经病变不同治疗方法的价值仍需在未来进行前瞻性评估。
