A subarachnoid hemorrhage occurs in about 10 out of 100,000 people each year. This bleeding leads to irritation and constriction of blood vessels in the brain (vasospasm) in two out of three people affected within four to 21 days and thus to reduced blood flow. This can lead to a stroke and serious damage. In order to be able to diagnose and treat a constriction of the blood vessels at an early stage, there are various examination methods which, however, have various disadvantages such as radiation exposure of the patient, low sensitivity or high effort. Therefore, the prediction and timely therapy of vascular constrictions is currently only successful in a few cases before the reduced blood flow has already led to irreversible damage.
The aim of this study is to investigate whether the so-called retinal vascular analysis can be used in addition to previous standard examinations for the early detection of diseases of the cerebral blood circulation. This method has few side effects and has been successfully used for 50 years to examine the blood circulation in the eye.

Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.
Bleeding into the SUBARACHNOID SPACE due to CRANIOCEREBRAL TRAUMA. Minor hemorrhages may be asymptomatic; moderate to severe hemorrhages may be associated with INTRACRANIAL HYPERTENSION and VASOSPASM, INTRACRANIAL.
A group of rare, idiopathic, congenital retinal vascular anomalies affecting the retinal capillaries. It is characterized by dilation and tortuosity of retinal vessels and formation of multiple aneurysms, with different degrees of leakage and exudates emanating from the blood vessels.
Bleeding within the SKULL induced by penetrating and nonpenetrating traumatic injuries, including hemorrhages into the tissues of CEREBRUM; BRAIN STEM; and CEREBELLUM; as well as into the epidural, subdural and subarachnoid spaces of the MENINGES.
Bacterial infections of the leptomeninges and subarachnoid space, frequently involving the cerebral cortex, cranial nerves, cerebral blood vessels, spinal cord, and nerve roots. The type of causative organism varies with age and clinical status (e.g., post-operative, immunodeficient, or post-traumatic states). Clinical manifestations include the acute onset of fever, stiff neck, altered mentation, seizures, and focal neurologic deficits. Death may occur within 24 hours of disease onset. Pathologic features include a purulent exudate in the subarachnoid space, and diffuse inflammation of neural and vascular structures. (From Joynt, Clinical Neurology, 1994, Ch24, pp1-5)
