If treatment is not received, this bleeding can cause long-term problems such retinal detachment or scarring in addition to impairing eyesight. The underlying pathology originates in the brain and usually involves an intracranial hemorrhage, such as a subarachnoid hemorrhage (SAH), or several types of elevated intracranial pressure.

Trauma is the most common cause of intracranial hemorrhage. It can cause epidural hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage. Other condition such as hemorrhagic parenchymal contusion and cerebral microhemorrhages can also be caused by trauma. [3]
The most common cause of a subarachnoid hemorrhage is an aneurysm rupture due to the weakened blood vessel walls and increased wall stress. [48] The neurologic symptoms are produced by the blood mass effect on neural structures, from the toxic effects of blood on the brain tissue, or by the increasing of intracranial pressure. [49]
Subarachnoid hemorrhage: Find the cause of hemorrhage, treat aneurysm or arteriovenous malformation if necessary, monitor for clinical deterioration, manage systemic complications and maintain cerebral perfusion pressure and prevent vasospasm and bridge patient to angiographic clipping.
[14] Further, it says, the comprehensive center must show "expertise treating patients with large ischemic strokes, intracerebral hemorrhage and subarachnoid hemorrhage." [14] The center must serve a sufficient number of stroke patients to prove experience and must maintain an adequate number of dedicated beds in intensive care units. Typically ...
Intra-axial hemorrhage is bleeding within the brain itself, or cerebral hemorrhage. This category includes intraparenchymal hemorrhage, or bleeding within the brain tissue, and intraventricular hemorrhage, bleeding within the brain's ventricles (particularly of premature infants). Intra-axial hemorrhages are more dangerous and harder to treat ...
