Abstract In a standard square plastic or glass prism, averaging about 38 mm. square, two small holes were drilled, each about 5 mm. in length and 2 mm. wide, one into the base and the other in one side of the prism. The hole in the base of the prism was drilled perpendicularly at a point midway of this rectangular surface. The hole in the side of the prism was drilled perpendicularly at a point midway between the apex and the basal edge. The holes were then tapped to permit the ready insertion of a rod about 6 inches (15 cm.) long, with one end threaded to screw readily into either of these spiraled openings. The result was a simple prism holder which could be changed readily to a base-down, base-in or base-out position. In a more recent model the holes were not threaded. One end of the rod holder was References 1. Krimsky, E.: A New Prism Holder , Tr. Am. Acad. Ophth. 51:297, 1947 2. A Multiple Prism Holder , Krimsky Tr. Am. Acad. Ophth. 54:370, 1950.
