Patent ID: 7841718

Claim:
An apparatus for measuring visual sensitivity of a retina of an eye, said apparatus comprising: a stimulus presentation device; a pupillometer; and a computer system programmed to: (1) present through the stimulus presentation device a stimulus test to said eye, said stimulus test including a stimulus pair made up of a first stimulus and a second stimulus for illuminating areas within first and second regions of the retina, wherein the first stimulus illuminates an area within the first region but not any area within the second region and the second stimulus illuminates an area within the second region but not any area within the first region, and wherein the first and second regions of the retina are spatially separated from each other; (2) use the pupillometer to measure a pupillary response of the eye based on the stimulus test; and (3) from the measured papillary response, generate a pupillary response curve for said stimulus test.
