Eye movements in the blind

Objectives : Eye movements are necessary to stabilize the retinal picture and to find a new object. This seems useless for blind people, so why do they nevertheless have them. We report on an EOG study on 29 blind volunteers and 5 volunteers with closed eyes. Material and methods: We recorded eye movements by EOG and let the volunteers fulfill different exercises by following an acoustic running point by gaze, pointing, imagining in the room, listing words that begin with the vocal U and a finger labyrinth. Results: We found slow eye movements as well as pathological eye movements in the blind subjects. We found that blind subjects have a horizontal preferency.The duration of fixation of pictures is shorter in the blind subjects. The blind could even modulate saccade amplitudes . Discussion: Eye movements seem to be structural properties of the brain which prepare the organism for certain situations-even if they do not take place. We think that eye movements are partially independent of the experience of view. We did not expect that the blind subjects could modify gaze according to the subject. This leads to the hypothesis of a preformed dimensional system.
