ABSTRACT:
A system for an examination of an eye of a patient, the system including: (a) a head set attached to the head of the patient; (b) a screen attached to the head set, such that the eye of the patient is covered by the screen; (c) a plurality of light sources attached to the screen, such that light is projected from at least one of the light sources directly to a preselected area of the retina of the eye of the patient to form reflected light; (d) a light receiving device attached to the head set to receive the reflected light and to transmit a signal according to the received reflected light; (e) an eye tracking device to determine the position of the eye relative to the light receiving device; and (f) a microprocessor for receiving the signal and for analyzing the signal to determine a size of a pupil of the eye and an amount of light reflected from the retina of the eye, such that a pupillary light response is measured to perform the examination. Also provided is a method for using the system of the present invention to perform an examination of the visual field of an eye of the patient. Preferably, the light receiving device is also able to continuously track, or follow, the position of the eye relative to the light receiving device. The method of examination preferably includes the steps of tracking the position of the eye, stimulating a preselected area of the retina with light at a retinal threshold intensity and then measuring both pupillary size and the amount of reflected light in order to determine the field of vision of the patient.
