title: The early psychophysical disturbances in chronic open-angle glaucoma. A study of visual functions with asymmetric disc cupping.
abstract: Fourteen patients with elevated intraocular pressures, normal visual fields, and asymmetry of disc cupping were examined using a number of psychophysical tests. The results suggest that color vision and visually evoked potentials show early disturbances, but a contraction of the visual field is variable.
