ABSTRACT:
A head rest for instruments used for opthamological examination comprises two vertical columns mounted on the instrument base. Each of said columns carries a vertical post to which is attached a forehead rest spanning the space between the posts. Said posts are retracted with respect to said columns. Said columns also carry a transverse bar spanning the space between the columns and supporting a chin rest which is adjustable with respect to the base. The arrangement provides maximum freedom of movement around the patient's eyes for the physician or surgeon.
