Abstract : A technique for obtaining monocular and binocular visual acuity measurements from rhesus monkeys is described. This procedure involves a back-lit screen and projection mechanism which presents stimuli varying in size between 0.5 and 10 minutes of arc. The subject is rewarded by pressing one of four levers based on a discrimination between four Landolt rings. Subjective visual acuity data (OS, OD, and OU) are presented for one subject. (Author)
