Abstract
A pattern stimulus system is described that includes a hemispherical concave surface, a plurality of illumination sources, and a controller. The illumination sources are arranged on the hemispherical concave surface in a plurality of annular rows and a plurality of radial columns. The control is configured to operate the illumination sources to display a checkerboard pattern by illuminating a first subset of the illumination sources and dimming a second subset of the illumination sources. The control is further configured to invert the checkerboard pattern by dimming the first subset of the illumination sources and illuminating the second subset of the illumination sources. Methods are also described for using the pattern stimulus system to evaluate a condition of the eye and to diagnose diseases of the eye.
