Technical Field
The invention relates to the technical field of visual function correction training, in particular to a central visual nerve loss inhibition system and a central visual nerve loss inhibition method.
Background
The existing disinhibition training method can only be qualitative, for example, the existing Worth four-point test can only indicate whether the inhibition occurs, but can not be quantitative, so that the cognition inhibition is always hindered by the lack of quantitative measurement.
At present, the training method for inhibiting the amblyopia is carried out under the condition of single eye, and the strong eyes on the non-amblyopia side are completely blocked by covering or atropine; these training methods all aim to improve the vision of one eye and then restore the visual function of both eyes. The biggest problem of the training method is to neglect the rule of visual development and binocular vision formation, and to simply use the visual acuity and general binocular vision examination as the judgment standard, and consider that most of people with unbalanced binocular vision do not have the condition of binocular vision, and the binocular vision function can be recovered only after the single-eye vision is improved. Although the training method can improve the visual function of a part of patients, the potential functions in the visual system of the patients are not fully utilized to achieve the maximum training effect and efficiency; moreover, the most important defect of the training method is that once the period of visual plasticity sensitivity (8 years old) is passed, the training method has little significance for improving visual function.

Preferably, the minimum value of the first left-eye frame flicker adjustment key 5, the first right-eye frame flicker adjustment key 6, the second right-eye frame flicker adjustment key 7 or the second left-eye frame flicker adjustment key 8 is that no flicker is added to the first left-eye frame 1, the first right-eye frame 2, the second right-eye frame 3 or the second left-eye frame 4.
The colors of a first left eye viewing frame 1, a first right eye viewing frame 2, a second right eye viewing frame 3 and a second left eye viewing frame 4 are consistent; and in the initial state, the first left eye viewing frame 1, the first right eye viewing frame 2, the second right eye viewing frame 3 and the second left eye viewing frame 4 have the same brightness and do not flicker.
The present invention provides a central optic nerve loss inhibition method, comprising: firstly, finding out a point of disinhibition by changing information input of two eyes, then gradually reducing information input difference of the two eyes, and enabling a patient to continuously try to find out four frames until the information input by the two eyes is consistent; the patient can still see four boxes.
The method specifically comprises the following steps:
and S1, adjusting the central visual nerve loss inhibition system to be in an initial state, namely adjusting the brightness of the first left eye visual frame, the first right eye visual frame, the second right eye visual frame and the second left eye visual frame to be consistent and not to flicker.
S2, the trainer watches the first left eye viewing frame, the first right eye viewing frame, the second right eye viewing frame and the second left eye viewing frame, and judges whether to see four viewing frames.
S3, if the four frames cannot be seen, increasing flicker to the frames which cannot be seen until the trainee completely sees the four frames, finding the balance point of the two eyes of the trainee, and removing inhibition at the balance point;
after continuously watching for a certain time, reducing the flicker frequency of the unseen frames, breaking the balance point established for the first time, enabling the information of good eyes to be larger than the information of poor eyes, forcing the poor eyes to stare until all four frames are watched, and finishing the disinhibition training;
s4, if the patient can see four frames, the brightness of the four frames is not consistent; reducing the brightness of the frames of the good eyes to make the brightness of the four frames consistent, finding the balance point of the two eyes of the trainer, and removing the inhibition at the balance point;
after the eyes are continuously watched for a certain time, the brightness of the good-eye frames is improved, the balance point established for the first time is broken, the brightness of the good eyes is larger than that of the poor eyes, the poor eyes are forced to watch the eyes until the brightness of the four frames is completely consistent, and the disinhibition training is completed;
s5, when the flicker is added to the maximum value, the four visual frames still cannot be seen, and the contrast of the visual frames visible to the eyes is reduced on the basis; if the four visual frames can not be seen, the distance between the trainer and the visual frames is shortened until the trainer completely sees the four visual frames, and a balance point of the two eyes of the trainer is found;
and then after continuously watching for a certain time, prolonging the distance between the trainer and the sight frames, breaking the balance point established for the first time, reestablishing new balance until four sight frames are visible at the normal distance, then sequentially improving the contrast of the sight frames visible to eyes, reducing the flicker frequency of the sight frames visible to eyes until the four sight frames are completely seen, and finishing the disinhibition training.
Further, in the above-described central optic nerve loss inhibition system and central optic nerve loss inhibition method:
1. when inhibition exists, increasing flicker to the corresponding frame, if four frames are visible within the flicker frequency range of 500 s-100 s, if 300s is visible, the four frames are the balance point; then, reducing flicker in sequence (at the moment, good eye information is strong, poor eye information is weak, the process forces the poor eye to improve functions), namely breaking balance points, and watching until four frames are seen;
2. when the brightness is inhibited, the patient can see four boxes but the color is different; at this time, the good-eye contrast is reduced (i.e. the good-eye brightness is reduced) until the two-eye brightness is the same, which is the balance point; and then, the eye contrast is improved, the balance is broken, and the brightness of the four frames is consistent when the four frames are observed.
3. When the poor eye flicker is maximized, the four frames cannot be seen, and the good eye contrast is reduced; if the good-eye contrast is reduced to the minimum, the user cannot see the good-eye contrast, the distance is shortened, for example, the normal distance is 2.5m, four frames can be seen at 1m, the user moves back to 1.5m to see the good-eye contrast, and the like until four frames can be seen at the normal distance;
then, the eye contrast is increased until four frames are seen;
then, the difference eye flicker is reduced until four boxes are seen;
in the process of the inhibition removal, the poor eye observation is forced and promoted by enhancing the good eye information, so that the inhibition removal effect of the invention on the poor eye is achieved.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
