A visual prosthesis simulator with capabilities to simulate several retinal diseases including Retinitis Pigmentosa (RP) and Age-Related Macular Degeneration (AMD), as well as a visual representation of prosthetic vision, was constructed to simulate both eye-directed and head-directed percepts using normally sighted volunteers wearing a head-mounted display with an external scene camera. These head and eye pointed modes allow the effects of foveation in retinal prostheses to be studied.
