Abstract:
A small opening in the center of a rotating arc serves as a peephole to control central eye fixation. In central scotoma a small test light is inserted into this opening to facilitate attempted fixation. Readings are noted on an attached tangential grid plate using a pen with water-soluble ink. Such readings are then copied on a record sheet slipped over this plate.
