Eye movement sensor device

Abstract

The invention relates to an eye movement sensor device consisting of a helmet (1) which can be fitted to the head of a patient undergoing an ophthalmologic exam in an installation comprising a seat (10) and a screen (11) on which spots of light are projected in front of the patient. The aforementioned helmet (1) is equipped with a front light projector (2) which emits a spot of light in the direction of the screen (11) and means for recording images of each of the eyes, which register the movements from an angle that enables the eye to be seen in all of the positions thereof.Said recording means preferably comprise a video camera (6) which is disposed below the projector (2) in the helmet (1) and which focuses downwards on (i) a pair of mirrors (7) that are provided on both sides of the lower part of the helmet (1) below each eye respectively, in order to capture the specular reflection of the movements thereof, or (ii) two cameras (5) below each eye.

Description

technical field [0001] The invention has application in the field of ophthalmology, in particular for the detection, monitoring and optimization of further pathological treatments for specific eye movement abnormalities, e.g. Tremor (accelerated eye vibrations), eye movement abnormalities caused by ptosis (upper eyelid drooping), and examination of artificial eyes, etc. [0002] More particularly, the proposed eye movement sensor consists of a helmet, suitable for both adult and pediatric patients, provided with means for recording eye movements, in particular a video camera for both eyes or for each eye, said The camera records all eye movements as images from an angle that allows them to be picked up, where the angle of view is the maximum eye turn, such as looking down. Furthermore, the helmet has light emitters that emit light spots to the screen, which the patient needs to focus on for a very precise eye examination of said abnormality and to optimize the diagnosis.

Problems solved by technology

Children or even adults with any mental or physical disorder that can lead to erratic head movements may cause them to experience particularly large shifts in the position of the head, which in practice is easily detected by infrared detection devices due to the Reliable calculation of eye movements is not possible with respect to the gaze direction of a point outside the acquisition area of
