Abstract
A method of screening for retinal disease including directing a first light at a first portion of the retina, directing a second light at a second portion of the retina, measuring a first pupillary response of the eye as a result of the first light and a second pupillary response as a result of the second light, and generating an indication of a severity level of the retinal disease using the first pupillary response and the second pupillary response. Also, an apparatus that implements this method including a light source for directing a first light at a first retinal portion and a second light at a second retinal portion, a pupil measuring device for measuring the pupillary response of the eye as a result of the first light and second light, a processor in electronic communication with the pupil measuring device, and a memory in electronic communication with the processor.
