ABSTRACT:
The eye movement sensor comprises a helmet (1) adjustable to the head of a patient who is undergoing an ophthalmologic examination, in a unit with seat (10) and projection screen (11) of light spots in front, the same helmet (1) incorporating a front light projector (2) which emits a light spot towards the screen (11), as well as means of image recording of each one of the eyes, which records their movements captured from an angle which permits viewing the eye in all its positions. Said means of recording preferably consists of a video camera (6) disposed below the projector (2) of the helmet (1), focussing a pair of mirrors (7), incorporated on different sides of the lower part of the helmet (1) downward, under each eye respectively, to capture the specular reflection of its movements; or instead, two cameras (5) under each eye.
