In a chronic subdural collection, the problem is not discovered immediately and blood leaks from the veins slowly over time.
A subdural hematoma is more common in the elderly because normal brain shrinkage occurs with aging that stretches and weakens the bridging veins.

  Subdural hematoma - Wikipedia, the free encyclopedia
A subdural hematoma, also called a subdural hemorrhage, is a collection of blood between the dura (the outer protective covering of the brain) and the arachnoid (the middle layer of the meninges).
Subdural hematomas are most often caused by head injury, when rapidly changing velocities within the skull may stretch and tear small bridging veins.
Subdural hematomas are divided into acute, subacute, and chronic, depending on how quickly or slowly they take to form.

It is usually the result of hemorrhage into the middle or anterior fossa of the skull, but it may be the result of aerocele, increased cerebrospinal pressure, encysted collections of cerebrospinal fluid in the subdural or subarachnoid spaces, extradural hemorrhage, subdural hematoma, or edema from infection.

 AANS.org | Education and Meetings | AANS Scientific Journals | Neurosurgical Focus
The presence of craniocerebral disproportion that develops from any cause--external hydrocephalus, internal hydrocephalus, arachnoid cyst, or chronic subdural hematoma--makes the patient exceptionally susceptible to subdural hemorrhage after what would otherwise be inconsequential trauma.[5,14,18,21,26,30,35,37] In particular, the prevalence of subdural hematoma in case series of patients with external hydrocephalus seems significant.
In a study reported by Azais and Echenne,[5] "spontaneous" subdural hemorrhage was demonstrated in five of 41 patients with "benign enlargement of the subarachnoid spaces" on ultrasonography and computerized tomography scanning.
Whether or not external hydrocephalus imparts a special susceptibility to ocular hemorrhage is unknown; however, in the present case the involvement of the eyes seems severe in relation to the extent of the intracranial hemorrhage.
