Abstract

A system for treating binocular anomalies. The system includes one or more imaging devices, one or more visual displays, and a computing device. The imaging devices may include right and left imaging devices that capture images of a patient'"'"'s right and left eyes, respectively. The displays may include right and left displays that provide right and left visual stimulation, respectively. The computing device identifies right and left locations on the right and left retinas, respectively, based at least in part on images of right and left eyes, respectively. The brain fuses images positioned at the right and left locations on the retinas into a single image. The computing device transmits right and left positioning signals to the right and left displays, respectively, that indicate that the right and left visual stimulation, respectively, are to be displayed so they are positioned at the right and left locations, respectively, on the retinas.
