ABSTRACT
PURPOSE: To report a case of spontaneous suprachoroidal haemorrhage in a haemophilia patient immediately following ChAdOx1 nCoV-19 vaccination. CASE PRESENTATION: A 60-year-old man with haemophilia developed painful vision loss in his left eye a day following the ChAdOx1 nCoV-19 vaccination due to acute angle-closure glaucoma from a massive suprachoroidal haemorrhage. He had an extremely deranged coagulation profile; activated partial thromboplastin time (APTT): 89 s, normal range 29-35 s After factor VIII transfusion, ocular hypotensive therapy and systemic/topical steroids, the suprachoroidal haemorrhage and glaucoma resolved, but the vision remained poor. CONCLUSION: Spontaneous suprachoroidal haemorrhage may be seen in haemophiliacs with deranged coagulation profiles. In our case, it followed ChAdOx1 nCoV-19 vaccination, and we recommend caution and checking the coagulation profile in such patients apriori.
