An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can include at least one source for producing mechanical waves of several frequencies from a distance to the eye of the patient to generate at least one surface wave to the eye, a detector for detecting at least one surface wave from a distance from the eye to extract surface wave information, and a device for determining pressure information of the eye based on the surface wave information.

An automated 3D mapping and display system includes automated ultrasound probe position registration, calculation of the position of each pixel in the ultrasound image in reference to selected anatomical references, and storage of specified information on command. The system, during real time ultrasound scanning, enables ultrasound probe position and orientation to be continuously displayed over a body part diagram, thereby facilitating scanning and images interpretation of stored information. The system can record single or multiple ultrasound free hand frames in a video sequence or cine loop wherein multiple 2D frames of one or more video sequences corresponding to a scanned volume can be reconstructed in 3D volume images corresponding to the scanned region, using known 3D reconstruction algorithms. In later examinations, the exact location and position of the transducer can be recreated along 3D or 2D axis points enabling known targets to be viewed from an exact, known position.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

It has been discovered that even mild changes in cerebrospinal fluid (CSF) pressure or intracranial pressure (ICP) can be detected immediately as evidenced by distortions in the ONS surface structure. Further, the changes in the ONS persist after the CSF pressure has returned to normal. The stability of ONS distortions provides a means of detecting transient changes in brain pressure even when the use of the diagnostic ultrasound is delayed. One embodiment provides systems and methods for detecting or diagnosing brain injury by detecting distortions or deformations of the ONS, preferably using ultrasound.
