A computerized electro-oculographic system consists of a rotating chair (2) for the patient, surrounded by a cylindrical screen (18) on which projectors (12, 16) project the desired optical stimuli. The signals produced by eye movements are picked up by electrodes (6a-1), amplified (24, 26), calibrated (46), filtered (26) and digitized (28) for the interface (30) with a computer. (32). The tests to be performed are selected by means of a keyboard (44) which controls the computer according to its programs (36). The signals produced by the computer are then displayed (38) and / or recorded (40, 42). |
