Abstract : The present invention relates generally to clinical instruments for the examination of eyes, and more particularly to a portable instrument for self-examination of the pupil of the eye. Pupilometer instruments known in the art prior to the invention generally comprise large, substantially stationary devices which have significant power requirements and which need a separate operator to focus and align optics of the devices, to make measurements and to interpret results. The invention described herein comprises a compact, portable subject operated instrument for rapid and accurate measurements of the eye in substantially any environment, and has particular field utility as a pupilometer in the self-administered examination of pupil dilation. The invention includes a flashlamp and power source for illuminating the eye, a lens system for projecting an image of the e ye onto photographic film, and a calibrated grid imaged onto the film simultaneously with the image of the eye.
