Abstract
A pixel light source apparatus, system and method are disclosed for a stimulus source for visual pathway testing. A representative system includes a plurality of pixel light sources and a control and driver circuit. The pixel light sources are coupled to each other to form a partially-spherical dome, with each pixel light source arranged to emit light directed to a convergent location of the partially-spherical dome. The control and driver circuit implements a selected stimulus protocol to selectively energize each pixel light source to generate light stimulation to any arbitrary or selected portion of the retina of an eye of a human subject. A representative pixel light source comprises at least one elongated and optically opaque side wall; a rear wall; an illumination source; a first optical element defining a first light chamber; and a second optical element defining a second light chamber.
