Description

Intelligent digital synopsis machine

【Technical field】

The invention relates to an ophthalmic synoptic machine for checking the binocular vision function of visual organs, in particular to an intelligent digital synopic machine completely controlled by a computer.

【Background technique】

Binocular vision is the most advanced visual function of human beings. The binocular vision function refers to the coordinated, accurate, and precise simultaneous work of both eyes, which transmits the optical imaging of external objects to the brain through the visual pathway, and forms a complete impression with a three-dimensional sense of depth after analysis and processing by the visual center. Abnormal binocular vision will cause patients to be unable to accurately obtain concepts such as the shape, orientation, and distance of external objects, and cannot correctly judge and adapt to the positional relationship between themselves and the objective environment.

Abnormal binocular vision disease is a common clinical disease with a high incidence. Typical diseases include strabismus, amblyopia, visual fatigue and so on. At present, the commonly used clinical examination methods for binocular vision abnormalities include corneal light reflection method, visual field arc, prism, synoptism, Worth four-point method and Hexcel screen, etc. Among them, the synopic machine is the most comprehensive and commonly used binocular vision abnormal disease inspection method, which can be used to comprehensively check the three-level binocular vision function of the subject. However, the traditional synoptic machine is still in the manual operation mode, and its diagnostic accuracy depends on the physician's clinical operation experience. At the same time, the manual inspection process is boring and cumbersome, time-consuming, difficult for patients to tolerate, and labor-intensive for doctors. Even for professional physicians, the objectivity and accuracy of the examination results are often affected by factors such as the different techniques of the examiners or the subjective wishes at the time.

In order to simplify the operation of the synopic machine, someone has proposed a scheme of using an angular displacement sensor to read out and automatically record various rotation angles of the synopic machine (referring to Chinese patent application No. CN1593329A). The disadvantage of this solution is that in addition to manual reading and recording of various rotation angles, other major operations still need to be done manually by doctors, including the design of the inspection process, the adjustment of various rotation mechanisms, and the replacement of induced pictures. The observation of the patient's eye position must also be done by the doctor with both eyes, so the accuracy of the examination results still depends on the doctor's clinical operation experience.

In order to improve the objective accuracy of binocular vision abnormal disease-related examinations, someone proposes to use camera analysis to check strabismus (see Chinese patent applications CN10114767A and CN1836625A). The common feature of these schemes is that a single fixed-position camera is used to capture images of the subject's eyes during the inspection process, and after computer image processing, the eyeball rotation angle is calculated according to the plane displacement of the iris or pupil. Since the position of the camera is fixed, there is no simple linear relationship between the plane displacement of the iris or pupil and the rotation angle of the eyeball, and there are large individual differences in the size of the cornea, eyeball size, and axial length of the examinee, which leads to the accuracy of the detection. Poor and large measurement error. Simultaneously, the above-mentioned scheme has a single function, and only attempts to detect the degree of strabismus, but does not have other functions of the synoptic machine, such as the detection of simultaneous vision, fusion and stereoscopic vision.

The second camera 221 on the right side detects and calculates the disparity between the pupil position of the right eye and Purchin's spot. If the disparity is zero at this time, the degree of strabismus is zero; if the disparity is not zero, then according to the disparity data The first stepper motor 32 on the right side of the automatic drive drives the right rotary support 12 to rotate accordingly until the potential difference is zero, and now the angle of rotation of the right rotary support 12 is the angle of oblique viewing.

The right-rotating bracket 12 is synchronously diverging or cohesively rotating, so that the examinee's eyes are gazing hard at the fusion picture. If the subject has a fusion function, the eyes will follow the picture and do synchronous divergence or cohesion movement. At this time, the first camera 211 and the second camera 221 detect that the difference between the pupil and the Puerchin's spot is very small; when turning When the angle reaches the fusion limit, the subject's eyes give up the fusion, and the first camera 211 and the second camera 221 detect that the position difference between the pupil and the Puerchin's spot suddenly increases, then at this time, the left rotation bracket 11 and the right rotation bracket 12 The rotation angle is the fusion degree of the subject. If the subject's eyes do not follow the screen and do simultaneous divergent or cohesive movements, it can be judged that the subject's fusion function is abnormal.
