RT Journal Article SR Electronic T1 Anisocoria in an intubated patient with COVID-19 JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e240003 DO 10.1136/bcr-2020-240003 VO 14 IS 7 A1 Sam Myers A1 Minak Bhalla A1 Rohit Jolly A1 Saurabh Jain YR 2021 UL http://casereports.bmj.com/content/14/7/e240003.abstract AB 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.
