甲状腺相关视神经病变的研究进展

甲状腺相关视神经病变是甲状腺相关眼病的继发性病变，临床表现包括视力下降、色觉受损、相对性传入性瞳孔障碍、视盘水肿或萎缩等。眼科辅助检查表现为视野异常和视觉诱发电位异常等，影像学检查显示眶尖拥挤可辅助诊断。目前此病的发病机制未明，既往研究提出其与视神经压迫、牵拉和缺血有关。治疗方法包括大剂量糖皮质激素静脉冲击治疗、眼眶减压手术、眼眶放射治疗和生物制剂等。本文主要回顾流行病学特征、发病机制及临床诊治等方面的进展，以期为临床实践和研究提供参考。

Research progress of dysthyroid optic neuropathy

Dysthyroid optic neuropathy is an important secondary pathological condition of thyroid-associated ophthalmopathy, characterized clinically by several clinical manifestations, including reduced visual acuity, impairment of color vision, relative afferent pupillary defect, and optic disk edema or atrophy. Ophthalmological auxiliary examination shows abnormal vision field and visual evoked potential, etc., and imagining examination shows orbital apex crowding, which can assist diagnosis. The pathogenesis of this disease is still unclear. With previous studies proposing that it was related to optic nerve compression, stretch, and ischemia. Treatment methods include high-dose intravenous glucocorticoid, orbital decompression, orbital radiation therapy, and biological agent. This article systematically reviews the research progress on the epidemiological characteristics, pathogenesis, diagnosis, and treatment of this disease, with a view to providing useful reference for future in-depth clinical practice and scientific research.
