Abstract
An apparatus and method for automated perimetry. A patient interface is adjustable with respect to a previously positioned patient rather than requiring the patient to position him or herself with regard to the perimeter. Fine adjustment of the patient interface with respect to the patient is possible while a perimeter dome is moved away from the patient and patient interface. Once positioned, the perimeter dome is moveable to a position adjacent the patient. A visual stimulus generating and directing device is preferably contained in a first module attachable to the dome. The visual stimuli are directed to various locations in the dome. An optional feature includes an eye sensing device which continuously monitors the size and position of a patient's pupil and correlates this information to the projected stimuli to verify the patient's fixation during testing. The eye sensor is preferably contained within a second module attachable to the dome. A connection device allows connection of either or both the projector and eye sensor to a stand alone processor. The device and method provide for industry standard tests and results, while being of a size which is portable and of a structural cooperation which does not require field servicing.
