We present two cases of blunt ocular trauma with clinical findings and complementary tests compatible with traumatic optic neuropathy (TON), and progression to sectorial optic atrophy.
TON have an essentially clinical diagnosis, and in the last few years has been treated with high doses of intravenous steroids, based on weak evidence of the benefit of the steroids in cases of medular trauma. Nevertheless, subsequent studies have concluded that there is a relatively high proportion of cases in all series with spontaneous visual recovery, and there was no convincing evidence of a benefit of steroids compared to observation only.
我们呈现了两例钝性眼外伤病例，其临床症状及辅助检查结果与创伤性视神经病变（TON）相符，并进展为扇形视神经萎缩。
TON主要依靠临床诊断，在过去几年中，基于类固醇对脊髓损伤病例有益的证据不足，一直采用大剂量静脉注射类固醇进行治疗。然而，随后的研究得出结论，在所有系列病例中，有相当比例的患者视力可自发恢复，且与仅观察相比，没有令人信服的证据表明类固醇有治疗益处。
