Abstract
OUR PREVIOUS studies1 on optic nerve sheath hemorrhage included one case which seemed unique as regards the possible complications of angiography. This communication summarizes the important features of that case. In brief, this patient developed massive unilateral optic nerve sheath and intraocular subhyaloid hemorrhage on the side on which the carotid artery was injected with 70% iodopyracet (Diodrast). There was only a small amount of blood in the left subdural optic nerve space. No intracranial meningeal hemorrhage was found at autopsy. It has been stated by other authors2 that in cerebral subarachnoid hemorrhage blood is forced under pressure through the optic foramen. Since no intracranial meningeal bleeding occurred in this case, it is evident that the nerve sheath hemorrhage can occur as an isolated phenomenon. REPORT OF A CASE R. R., a 36-year-old white woman, had had congenital heart disease with cyanosis since birth. Studies revealed polycythemia and
