A pupil function analyzer has three major subsystems; an electro-optical system, an electronic interface system and a computer/software system. The electro-optical system can, in turn, be described in terms of three subsystems; one that delivers controlled lights to the patient's eyes, another that forms images of the two pupils on a video camera, and a third that moves the optics to maintain alignment with the patient's eyes. The electronic interface system converts signals from the video camera into digital signals to be read by the computer and also responds to the computer to move motors for the maintenance of optical alignment and also operates the light stimuli. The computer/software saves and analyzes the signals sent by the electronic interface, controls the alignment motors, and provides an operator interface, so that the operator can select tests and examine the results.
In an ophthalmological instrument for examination of pupillary responses and extrinsic eye muscle balance including pupil imaging optics, a video camera having a photosensitive image plane on which images of a patient's pupils are focussed by the pupil imaging optics, a programmed computer, light stimulus devices for selectively stimulating the retinas of a patient's eyes under the control of said computer, and a display screen connected to said video camera for providing a display of a patient's pupils as they react to said light stimulus devices and also displaying text and graphics generated by said computer, said computer being programmed to perform the method comprising the steps of:
