[0002] With the development and popularization of video terminals, the public's demand for near vision is increasing, and more and more people are experiencing various functional "eye problems." Binocular vision function tests are an important means of evaluating the ability of the two eyes to work together. They are mainly used to diagnose problems such as visual fatigue, strabismus, amblyopia, and abnormal stereopsis. They also provide a basis for myopia control, refractive correction, and vision training.

BRIEF DESCRIPTION OF THE DRAWINGS
[0050] Figure 1 This is a flow chart of the RFPA four-dimensional professional inspection method proposed in the present invention. DETAILED DESCRIPTION
[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0052] Reference Figure 1 The RFPA four-dimensional professional examination method includes examining the patient's monocular and binocular vision in their natural state to obtain the first examination result. Here, the natural state refers to the examinee's usual eye state, such as naked eyes, wearing glasses, wearing contact lenses, or with full refractive correction, etc. If the examinee does not usually wear glasses, the examination is performed under the naked eye; if the examinee usually wears glasses, the examination is performed with the glasses; if the examinee usually wears contact lenses, the examination is performed with the contact lenses. The first examination results specifically include the following results:
[0053] If the binocular vision is not lower than the monocular vision, the first examination result is no obvious binocular vision abnormality; otherwise, the first examination result is suspected of binocular vision abnormality;
[0054] If the distance and near vision of one eye are normal, the first examination result shows that the patient's daily vision is normal;
[0055] If the patient's distance vision is low in one eye and the near vision is normal, the initial examination result shows that the patient has a refractive error. If the monocular vision improves with the pinhole microscope, this conclusion can be verified.
[0056] If the distance vision of one eye is normal and the near vision is low, the patient may be suspected of having abnormal accommodation function. If the near vision is improved with the help of pinhole mirror, this conclusion can be verified.
[0057] If the vision of both near and far vision in one eye is low, and the vision is improved and close to normal vision level after using pinhole spectacles, the patient may be suspected of having refractive error and abnormal accommodation function.
[0058] If the vision does not improve or decreases after using the pinhole mirror, and the first examination result is suspected functional vision loss, further examination is needed based on the patient's medical history to confirm the diagnosis. If functional vision loss is suspected, further examination is needed to rule out amblyopia.
[0059] Based on the first examination result, the patient's near and far fusion is examined to obtain a second examination result. Specifically, based on the first examination result, the patient's near and far fusion is examined using the Worth 4dot sight mark and red and green filters under the premise of full refractive correction to obtain the second examination result. The second examination result specifically includes the following results:
[0060] If the patient observes 4 optotypes, the second examination result is normal fusion;
[0061] If the patient observes 5 optotypes, a secondary examination result of abnormal fusion is obtained;
[0062] If the patient observes two optotypes, a secondary examination result of abnormal fusion is obtained;
[0063] If the patient observes 3 optotypes, a secondary finding of fusional abnormality is obtained.
[0064] Based on the second examination result, the patient's near and far eye alignment is examined to obtain a third examination result. Specifically, under the premise of the patient's full refractive correction, the patient's near and far eye alignment is examined using the alternating cover method (combined with the prism neutralization method for quantification) (this examination is a direct measurement of binocular fusional vergence function and an indirect measurement of monocular accommodation function) to obtain the third examination result. The third examination result specifically includes the following results:
[0065] If both the far and near eye positions are within the normal range (i.e., far eye position: 2△eso~4△exo, near eye position: 5△eso~6△exo), the third examination result is no obvious eye position abnormality;
[0066] If the distance eye alignment is normal and the near eye alignment is abnormal, a third examination result is obtained that suggests a convergence problem;
[0067] If the amount of near eye esotropia increases, a third examination result is obtained that is suspected of hyperconvergence;
[0068] If the amount of near-eye exotropia increases, a third examination result is obtained that may indicate convergence insufficiency;
[0069] If the distance eye position is abnormal and the near eye position is normal, a third examination result is obtained that suggests a divergence problem;
[0070] If the amount of esotropia in the far eye increases, a third examination result is obtained that may indicate insufficient divergence;
[0071] If the amount of exotropia in the far eye increases, a third examination result is obtained that may indicate excessive divergence;
[0072] If both near and far eye alignment are abnormal, the third examination result is suspected to be simple heterotropia;
[0073] If the amount of esotropia increases in both near and far eye positions, the third examination result is suspected to be simple esotropia;
[0074] If the amount of exotropia increases in both near and far eye positions, the third examination result is suspected to be simple exotropia.
[0075] Based on the third test results, under the premise of full refractive correction, the patient's visual clarity perception difference of the 20 / 30 optometry chart is examined using ±2.0D reversal at a distance of 40cm for both eyes. Here, the monocular accommodation function can be directly measured, and the binocular fusional vergence function can be indirectly measured to obtain the fourth test results. The fourth test results specifically include the following results:
[0076] If the positive and negative lenses of both eyes are clear and have no difference, and the fourth examination result shows that there is no obvious abnormality in the monocular accommodation function and vergence function;
[0077] If the monocular minus lens is clear and there is no difference in the clarity of the binocular plus lens, and the monocular plus lens is clearer than the binocular plus lens, the fourth examination result is suspected to be a positive fusional vergence abnormality in the binocular vision (such as convergence insufficiency, simple exophoria, etc., and discomfort symptoms will occur after long-term near vision);
[0078] If the plus lenses for both eyes are clearer than the plus lenses for one eye, the fourth examination result indicates that there is a suspected difficulty in accommodating one eye (such as visual fatigue, pseudomyopia, and excessive accommodation, which may cause discomfort after long-term near vision);
[0079] If the monocular plus lens is clear and there is no difference in clarity between the two eyes, and the monocular minus lens is clearer than the binocular minus lens, the fourth examination result is suspected to be a vergence abnormality with negative fusion in binocular near vision (such as excessive convergence, simple esotropia, etc., which may cause discomfort after long-term near vision);
[0080] If the binocular negative lens is clearer than the monocular negative lens, the fourth examination result is suspected to be abnormal monocular accommodation stimulation (such as insufficient accommodation, unsustainable accommodation, unequal accommodation, delayed accommodation, etc., and discomfort symptoms will occur after long-term near vision);
[0081] If both the positive and negative lenses of one or both eyes are not clear, a fourth examination result is obtained that indicates suspected monocular accommodation failure (such as accommodation spasm);
[0082] If both eyes are less clear than one eye, the fourth examination result is suspected to be accompanied by fusional vergence dysfunction for near vision.
[0083] Determine whether the patient's binocular vision function is abnormal based on at least one of the first examination result, the second examination result, the third examination result, and the fourth examination result, specifically:
[0084] According to the first examination result showing that the near / far visual acuity of both eyes is lower than that of one eye, the second examination result showing that the patient sees 4 / 5 / 2 / 3 visual marks, the third examination result showing that the distance eye position is normal or the distance eye position exophoria and the near eye position exophoria are increased, the fourth examination result showing that when observing the 20 / 30 visual mark card at 40 cm, the monocular positive lens is clearer than the binocular positive lens, and the fourth examination result showing that the patient is suspected of having positive fusional vergence dysfunction, the binocular vision function examination result of suspected convergence insufficiency or simple exophoria is obtained. Here, in the first examination result, the binocular vision is lower than the monocular vision, including distance vision and near vision, which is abnormal. According to visual physiology, normal binocular vision should be about 1.4 times that of monocular vision. Lower binocular vision indicates that the problem is caused by abnormal binocular vision function; regardless of the interference of positive or negative lenses, if the monocular vision is better than the binocular vision, it means that the binocular vision function is abnormal; if the positive lenses of both eyes are not good, it means that there is a problem of abnormal positive fusional convergence function for near vision; if the negative lenses of both eyes are not good, it means that there is a problem of abnormal negative fusional convergence function for near vision.
[0085] According to the first examination result that the near / far vision of both eyes is lower than the near / far vision of one eye, the second examination result that the patient sees 4 / 5 sight marks, the third examination result that the distance eye position is normal or the distance eye esotropia increases and the near eye esotropia increases, the fourth examination result that when observing the 20 / 30 sight mark card at 40 cm, the monocular minus lens is clearer than the binocular minus lens, and the fourth examination result that the patient is suspected of having negative fusional vergence dysfunction, the binocular vision function examination result of suspected hyperconvergence or simple esotropia is obtained.
[0086] According to the first examination result showing that both monocular and binocular vision were normal, the second examination result showing that the patient saw 4 sight marks, the third examination result showing that both near and far eye positions were normal, the fourth examination result showing that when observing a 20 / 30 sight card at 40 cm, the positive and negative lenses of the monocular eye were clearer than the positive and negative lenses of the binocular eye, and the fourth examination result showing that the patient was suspected of having abnormal fusional vergence function at near vision, the examination result of abnormal binocular vision function was obtained.
[0087] In specific implementation, whether the patient's binocular vision function is abnormal can be determined by f(x)=W1+W2+W3;
[0088] f(x)<0, the binocular vision function is abnormal as excessive convergence;
[0089] f(x)>0, the binocular vision function is abnormal and is called convergence insufficiency;
[0090] f(x) = 0, binocular vision abnormality is simple (or fusional vergence abnormality). When the distance and near eye positions are within the normal range, and the reversed monocular plus and minus lenses are clearer than the binocular plus and minus lenses, it is fusional vergence abnormality; otherwise, it is simple.
[0091] Wherein, W1 is the first test result: if the near vision of both eyes is lower than the near vision of one eye, W1 takes the value of 1; if the distance vision of both eyes is lower than the distance vision of one eye, W1 takes the value of -1; otherwise, W1 takes the value of 0;
[0092] W2 is the result of the third examination: if the distance eye alignment is normal but the near eye exotropia exceeds the normal value, W2 takes the value of 1; if the distance eye alignment is normal but the near eye esotropia exceeds the normal value, W2 takes the value of -1; otherwise, W2 takes the value of 0;
[0093] W3 is the fourth test result: when observing the 20 / 30 sight card at 40 cm, if the monocular plus lens is clearer than the binocular plus lens, the value of W3 is 1; if the monocular minus lens is clearer than the binocular minus lens, the value of W3 is -1; otherwise, the value of W3 is 0.
[0094] In the above-mentioned embodiment of the present invention, the four-step visual function examination method can quickly and qualitatively determine whether the patient has refractive error, functional vision loss, binocular vision function, monocular accommodation function, and binocular fusional vergence function abnormalities. This provides a basis for providing healthy, clear, comfortable, and long-term optometry diagnosis and treatment services.
[0095] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
