Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.
It appears as an aftereffect of an intracranial hemorrhage (such as traumatic brain injury or subarachnoid hemorrhage). Intraocular bleeding results from the condition's abrupt and severe rise in intracranial pressure, which is then conveyed to the eyes through the optic nerve sheath. Terson's syndrome's most frequent cause.
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]
People on these medications can have a subdural hematoma after a relatively minor traumatic event. Another cause can be a reduction in cerebrospinal fluid pressure, which can reduce pressure in the subarachnoid space, pulling the arachnoid away from the dura mater and leading to a rupture of the blood vessels. [10]
Subarachnoid hemorrhage approximately doubles mortality. [142] Subdural hematoma is associated with worse outcome and increased mortality, while people with epidural hematoma are expected to have a good outcome if they receive surgery quickly. [76] Diffuse axonal injury may be associated with coma when severe, and poor outcome. [10]
Intraocular hemorrhage (sometimes called hemophthalmos or hemophthalmia) is bleeding inside the eye (oculus in Latin). Bleeding can occur from any structure of the eye where there is vasculature or blood flow, including the anterior chamber , vitreous cavity, retina , choroid , suprachoroidal space, or optic disc .
The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.
