Does low blood platelets cause bloodshot eyes?
It depends how low your platelets are. Though normal is between 150,000 and 400,000/ μl (microlitre) problems don’t usually occur until levels drop to under 20,000. There are many fairly benign causes such as viral suppression and ITP ( idiopathic thombocytopaenic purpura ) which is treated with steroids. Certainly at very low levels spontaneous bleeding can occur.
