In a method of non-invasively obtaining information on intracranial pressure of a patient, during a first time period, a plurality of facial veins of the patient are occluded by applying external pressure to each of the plurality of facial veins, which emanate from the periorbital region. During the first time period, external pressure is applied to a designated vein (17) connected to an intracranial vessel at a location within the region, upstream of the occlusion of the plurality of facial veins. Changes in the geometry of the designated vein (17) caused by the external pressure are observed to obtain at least one first value related to venous pressure in the designated vein (17). The at least one first value is processed to obtain information on intracranial pressure. The method enables measuring pressure values that are closely related to intracranial pressure without the need for measurements within the intracranial space. Instead, an occlusion establishes a direct pressure communication between the intracranial vessel and the designated vein, which can be easily examined outside the head.
