ABSTRACT:
Visual disorders of the retina are identified and assessed by stimulating the eye(s) with an array of controllable optical elements wherein the controllable elements are activated with M-sequences. The transient responses of the eye to the activation of the array of elements is obtained and processed using the known M-sequences to identify any areas of disease. The optically controllable elements can produce flashes of light or change colors in response to the energization thereof.
