Claim One:
1. An automated system for determining the existence of dyslexia, said system comprising: (a) means for stimulating a predetermined pattern of eye movement in a subject to be tested for dyslexia, (b) means for detecting eye movement in a subject observing said means for stimulating eye movement, said detecting means providing an electrical output signal in response to said movement, (c) processor means for receiving said electrical output signal, said processor means further including, (i) means for sampling the output signal to obtain a series of successive eye positions, (ii) means for converting said successive eye positions into data representing eye movements, (iii) means for analyzing said data by direction, duration and amplitude in order to differentiate between forward saccadic movements, reverse saccadic movements, pursuit movements and fixations, (iv) means for comparing the number and placement of reverse saccadic eye movements with predetermined patterns to determine the existence of dyslexia, (d) output means for enabling display of said diagnosis.
