Claim One:
1. A method of simultaneously evaluating a visual field and retinal function in a patient, the method comprising a. using an instrument containing a light source to shine a relatively stronger pulse of light on an area of the retina wherein a circular image is projected on the retina and an individual is instructed to look at the center of the circle until the patient indicates lack of seeing the light source thereby indicating bleaching the patient's retinal photoreceptors; b. using the instrument to shine a plurality of subsequently weaker pulses of light than in step a on the same area of the retina until the patient indicates seeing the light source thereby measuring recovery of the bleached retinal photoreceptors, and c. assessing the time interval between a time the patient indicates seeing the light source as in step a, and a time the patient indicates seeing the light source as in step b, to measure the recovery of the bleached retinal photoreceptors as the patient's photoreceptor recovery thereby indicating the patient's photoreceptor health compared to photoreceptor health of a normal individual.
