    Bi-tube optometric system for the measurement of binocular vision. A system is described which, being light and transportable, makes possible the measurement and treatment of binocular vision. The system consists of two tubes mounted on the plane of a circular scale and horizontally separated by a bar of variable length depending on the interpupillary distance. The measurement of the angle formed by the two tubes allows the measurement of the possible binocular anomaly. (Machine-translation by Google Translate, not legally binding)

    DESCRIPTION

    Bi-tube eye system for measuring binocular vision.

    Technical Sector 5

    The invention falls within the technical sector of optics, as measuring equipment and treatment of binocular vision problems.

    State of the art 10

    The optometric equipment for the evaluation of binocular vision and its subsequent treatment are generally sophisticated instruments that meet different parameters of the visual examination to, afterwards, treat refractive error with appropriate refraction using glasses and contact lenses but also with therapy visual if an accommodative and / or binocular anomaly is associated. This last anomaly of binocular vision is mainly caused by diplopia or double vision when both eyes do not have the same image associated harmonically in both retinas simultaneously, preventing the reception of a simple image at the cortical level.
     twenty
    This deviation of the eyes is measured with prisms or tests with fusion dissociators that allow, on a scale (always subjective because it depends on the patient's response) to check its value, both symmetrically and asymmetrically with respect to the fixation line. There is an instrument, the synophor, which also allows the evaluation of this deviation in the three spatial axes. In synophor, it is a very heavy equipment and it remains fixed on a table for evaluation and treatment, with different accessories to show the patient different images that evaluate different stages of binocular vision: simple, binocular vision, fusion and relief vision.

    Therefore, it would be desirable to have light and transportable equipment. 30

    The device proposed in this invention can be manufactured in a lightweight material and also allows to measure the deviation and treat it partially or totally depending on the binocular anomaly that remains after compensation of the refractive error. It is a sufficiently light device for use anywhere outside of the optometric cabinet 35 and by its arrangement allows real-time measurement.

    Detailed description of the invention

    Biometric tube eye system for binocular vision. 40

    The bi-tube consists of two tubes (1), one for each eye, being of light material (such as light metal or plastic) and a second element, the scale (2), on whose plane the tubes are mounted and which allows the measurement of deviations depending on the angle of one tube with respect to the other. Four. Five

    The tubes can be of different thicknesses and lengths. The scale is in degrees for values between 0º and 360º although the measurement clearance is much smaller. The angle formed by the tubes may vary depending on the vergence limits.
     fifty
    The tubes are separated by a bar (3) that can be shortened or lengthened depending on the interpupillary distance of the patient or distance between lines of sight of each eye.

    Embodiment of the invention
     5
    The present invention is further illustrated by the following examples, which are not intended to be limiting in scope.

    Example 1.
     10
    This example refers to the dimensions of the tubes.

    The bi-tube is formed by two tubes (1) of equal length (260 mm) and diameter (3.5 mm) of light metal and are mounted on a scale (2) in degrees made of rigid plastic to know the deviation of the eyes. The union between the tubes and the scale is done with 15 welds.

    Example 2

    This example refers to the use of the bi-tube as a diagnostic method of binocular vision.

    To the terminal of each tube is added an accessory of a larger diameter, subject to pressure and that includes an image for evaluation of the fusion (ability of the brain to join two images, with or without differences between them, of greater or lesser degree of cohesion and complementarity, to achieve a unique image, combination of those visualized by each eye).

    For this measure the relative positions of the tubes are modified, in any direction, subjectively assessing whether the person receives a single image (each image 30 has exclusive signals according to the eye used) that merges or unites neurologically since, otherwise, the double image with relative positions of these. they allow diagnosing both the binocular visual problem and the amount of deviation, provided that it does not suppress one of the two images.
     35
    Thus, when the person indicates that he sees double at the precise moment in which he separates the tubes approximately 2 cm, divergently, it can be concluded that his negative fusional vergences (ability to maintain a fused image when the object moves sagittally away from the eyes or of the person, in this case, when we separate the images of the tube house simulating the distance from the object) they are reduced and 40 is interpreted as excessive convergence by prolonged work from near distance to shorter distances than normal.

    Example 3
     Four. Five
    This example refers to the treatment of binocular vision using the bi-tube.

    The movements of the tubes are carried to the limits doing it in a sense where the person has problems and, progressively, it is possible to increase the values of separation of the images keeping the resulting image fused neurologically.
