What are the methods of binocular visual function examination

First, synoptophore, which divides the visual process of binocular vision into three levels according to its simplicity and complexity, has been widely used by clinical workers. That is, binocular simultaneous vision, fusion power and stereopsis. Synoptophore can check monocular inhibition, abnormal retinal correspondence and three-level binocular vision.

Second: worth four point test, four point test can check monocular inhibition, diplopia and binocular fusion function. The examination methods are as follows: the patient wears red and green glasses and observes four lights at 33cm or 6m, one red, two green and one white. The red recording colors of glasses and four point lights complement each other, that is, the eyes with red glasses can't see the green light, they can only see the red light or regard the white light as the red light; the eyes with green glasses can't see the red light, they can only see the green light or regard the white light as the green light.

Fourth: the prism test, if the patient's Micro strabismus or strabismus correction surgery still exist fovea inhibition, this kind of fovea dark spot is difficult to find, in order to estimate the quality of binocular vision of patients can choose this examination method. The patient looks at a point light source directly in front of him, puts the prism with the bottom outward in front of one eye, and observes whether the other eye has two-way movement.
