强直性瞳孔在临床工作中较为少见，容易被误诊，典型的强直性瞳孔为单侧，随着病程的进展，逐渐转变为双侧。新发双侧强直性瞳孔更是极为罕见，应当引起重视。其典型的临床表现包括瞳孔散大、瞳孔运动迟钝、节段性瞳孔麻痹、无其他眼部器质性病变。依据病因可以分为继发于急性眼内肌麻痹、合并有全身疾病以及特发性三类。目前治疗方面多以病因治疗为主。
Tonic pupil is rare in clinical work and likely to be misdiagnosed. The typical tonic pupil is unilateral, which gradually turns to bilateral with the progress of disease. Newly bilateral tonic pupil is extremely rare, which captivates widespread attention. Typical clinical manifestations include dilated pupils, slow pupil movement, segmental pupillary palsy, and no other ocular diseases. On this basis, the causes can be divided into three categories, including secondary to acute intraocular myoparalysis, complicated with systemic disease and idiopathic type. At present, etiological treatment is the main treatment.
视神经脊髓炎相关性视神经炎(neuromyelitis optica spectrum disorder optic neuritis，NMO-ON)是一种常见的视神经炎(optic neuritis，ON)类型。女性非白种人占优势，损伤严重，双侧受累较多，视力预后差。我国有很大部分特发性ON最终诊断为NMO-ON。在相关实验室、光学相干断层扫描(optical coherence tomography，OCT)、磁共振(magnetic resonance imaging，MRI)等技术支持下，目前对NMO-ON的认识有了很大的进步，治疗方式除了皮质类固醇外还有免疫球蛋白、血浆置换及免疫抑制剂等。但提高NMO-ON的诊疗水平还有很长的路，更好地认识NMO-ON有助于更快速的诊断、更规范的治疗、更良好的预后。我们可以联合神经科开展多中心大样本量前瞻性的临床对照研究。
Neuromyelitis optica spectrum disorder- optic neuritis (NMO-ON) is a common type of optic neuritis (ON). This affliction is predominant in female non-Caucasians, with severe injury, more bilateral involvement, and poor visual prognosis. In China, a large proportion of idiopathic ON is ultimately diagnosed as NMO-ON. Our understanding of NMO-ON has made great progress under the technical support, such as the relevant laboratory, optical coherence tomography (OCT), magnetic resonance imaging (MRI). In addition to corticosteroids, immunoglobulin, plasmapheresis and immunosuppressive agents are also available for treatment. However, there is still a long way to improve the diagnosis and treatment level of NMO-ON. A better understanding of NMO-ON contributes to faster diagnosis, more standardized treatment, and better prognosis. We should cooperate with the neurology department to conduct a multi-center, large sample size prospective clinical control study.
