A Terson
Terson's syndrome = Terson described vitreous hemorrhages occurring in patients with subarachnoid hemorrhage and attributed it to a sudden increase in venous pressure that ruptures epipapillary and peripapillary capillaries. About 20% of patients suffering of subarachnoid, or subdural hemorrhages develop intraocular hemorrhages that in most cases are confined at the posterior pole. Intraretinal and subretinal bleeding may also be present, usually from the optic disc and retinal blood vessels. Subhyaloid hemorrhages are usually present. In most cases these hemorrhages clear spontaneously and vision function is unaffected.
