A 37-year-old patient presented to our emergency department with sudden onset decreased vision with a history of being treated for COVID 19 3 weeks earlier. On examination, she was found to have a tonic right pupil, which was confirmed with a dilute pilocarpine test. As tonic pupils are known to be caused by neurotropic viruses and our current understanding of the SARS-CoV-2 is that it does affect the nervous system, we feel that the tonic pupil in our patient may be secondary to COVID 19.
一位 37 岁的患者因 COVID-19 于 3 周前接受治疗后突发视力下降而到我们的急诊部就诊。检查发现患者右侧瞳孔强直，用稀释的毛果芸香碱试验得到了证实。由于强直瞳孔已知是由亲神经性病毒引起的，而我们目前对 SARS-CoV-2 的了解是它确实会影响神经系统，因此我们认为我们患者的强直瞳孔可能是 COVID-19 引起的。
