The effects of COVID-19 on the eye are still widely unknown. We describe a case of a patient who was intubated and proned in the intensive care unit (ICU) for COVID-19 and developed unilateral anisocoria. CT venogram excluded a cavernous sinus thrombosis. MRI of the head showed microhaemorrhages in the midbrain where the pupil reflex nuclei are located. After the patient was stepped down from ICU, intraocular pressure (IOP) was found to be raised in that eye. A diagnosis of subacute closed angle glaucoma was made. It is important for clinicians to rule out thrombotic causes in patients who develop acute anisocoria. It is also crucial to measure IOP in patients who develop ophthalmic pathology and have been proned for extended periods.
COVID-19 对眼睛的影响仍知之甚少。我们描述了一例患者因 COVID-19 在重症监护病房（ICU）插管并俯卧位，出现单侧瞳孔不等大。CT 静脉造影排除了海绵窦血栓形成。头部 MRI 显示位于瞳孔反射核的中脑微出血。患者从 ICU 转科后，发现该眼眼压升高。诊断为亚急性闭角型青光眼。对于出现急性瞳孔不等大的患者，临床医生排除血栓形成的原因很重要。对于出现眼部病变并长时间俯卧位的患者，测量眼压也至关重要。
