A behavorial program is described which permits assessment of visual functioning in rhesus monkeys immediately following laser- induced foveal impairment. Six rhesus monkeys were trained on a visual discrimination problem involving Landolt rings. Subjects received stimuli via viewing tubes to either the right or left eye on a random basis. An equal number of stimuli were presented to each eye. Midway through the behavioral program the right eye was exposed to a neodymium laser. Post-exposure behavioral testing began immediately thereafter. The behavioral data predicted the occurrence of foveal impairment as verified by fundus photographs taken approximately 1 hour after exposure. Author
