The NovaVision HMP™ Head Mounted Perimeter is an automated portable visual field screening device that quickly and reliably tests a 60 X 44º visual field using a suprathreshold 3 zone testing strategy. The HMP can be easily used in multiple office locations and with patients who may not have been able to sit at a table mounted device due to physical constrains, making the HMP ADA-compliant. Additionally the HMP delivers detailed information with test points every 4º. The hardware is comprised of a head mounted display with state-of-the-art optics and a response button for patient use and an intuitive touch screen and a robust processor for physician use that comes in a carrying case convenient for travel. Physicians and practices on the go can screen patients for a possible visual field deficit, which may indicate presence of disease or brain injury.
