Visual acuity in a stumptail macaque.
Visual acuity in a normal stumptail macaque is 1.4 minutes of arc-similar to man's. Destruction of the fovea by photocoagulation decreased acuity to 9 minutes of arc. These facts suggest that the fovea in the macaque has the same physiological role in visual acuity as in man.
