Stereoscopic vision and depth perception testing is important in identifying diseases such as Amblyopia, Strabismus, Suppression and Stereopsis. Stereovision is how each eye may see an object from different angles, but combines these angles to give us a 3D image. There are many stereoscopic/depth perception tests on the market. Random Dot E is geared more for children while the others to adults. The patient will be asked to identify the “raised” letter, shape or animal to measure depth perception and identify if the patients eyes are working together to identify the intended image.
