Apparatus and method for measuring retinal function in discrete regions of a retina includes selecting a discrete region of a retina having ganglion cell axons extending therefrom and to an optic nerve head and directing a linearly polarized beam of light on a probe region of retinal nerve fibers proximate the optic nerve head. Thereafter the discrete region is stimulated with light. Apparatus is provided for detecting light reflected from the probe region, before, during and after stimulation for producing an electrical signal corresponding to the amount of shifted linearly polarized light as a function of time.
