Bilateral superior ophthalmic vein thrombosis, ischaemic stroke, and immune thrombocytopenia after ChAdOx1 nCoV-19 vaccination

Abstract

A 55-year-old woman presented with conjunctival congestion, retro-orbital pain, and diplopia. She had received her first vaccine against SARS-CoV-2—ChAdOx1 nCoV-19—10 days before admission. Both on the night after the vaccination and 7 days later, the patient reported marked flu-like symptoms and a fever. She had no medical history of visual problems, autoimmune disorders, stroke, thrombosis, thrombocytopenia, neurological disorders, or arterial disease risk factors—including hypertension, diabetes, or smoking.
