HOLMGREN has suffered from a relative central scotoma in his right eye, coming on from dazzling with light in 1880. In the region of the scotoma he has macropsia, metamorphopsia, and a certain degree of red blindness. By fixing a rectangular object with each eye he was able to determine the degree of the macropsia. With small objects the increase in apparent size was considerable, with larger objects it was less, and with objects of a certain size there was no apparent enlargement. This size corresponded in extent to the scotoma formed.
