Amblyopia correction and detection device

Abstract

The invention relates to a medical instrument for correcting and detecting amblyopia, in particular to a device for correcting and detecting amblyopia based on the principle of binocular balance. It includes two liquid crystal lenses embedded in the lens frame, a main board fixed on the lens frame, two light sensors respectively arranged on the inner surfaces of the two liquid crystal lenses, and a control system composed of a remote controller wirelessly communicating with the main board The main board is provided with a microprocessor, and the wireless receiver, the memory card module, the real-time clock, and the mode selection switch respectively communicated with the microprocessor, and the two liquid crystal lenses are respectively connected with the microprocessor on the main board for control, The two light sensors are respectively connected in communication with the microprocessor on the main board. The device can realize multi-mode amblyopia treatment and correction training, and the treatment and correction training modes can be adjusted arbitrarily according to the recovery status of individual patients. The device can cooperate with refractive correction treatment to obtain better amblyopia correction and binocular vision improvement Effect.

Description

technical field [0001] The invention relates to a medical instrument for correcting and detecting amblyopia, in particular to a device for correcting and detecting amblyopia based on the principle of binocular balance. The application of the device can more effectively treat children and adults with amblyopia, improve the treatment effect, and reduce recurrence after recovery. Background technique [0002] Amblyopia is a clinically common ophthalmic disease in children, with a clinical incidence rate of about 1-4% according to statistics. The current conventional treatment method is masking treatment. This method has been used for many years, and some shortcomings have been exposed in clinical practice: 1) Due to the influence of the mask on the appearance, the patient's medical compliance is poor, and the proportion of treatment abandonment is high; 2) The prognosis of some patients is not good, and the treatment effect is not significant; 3 ) recurrence is unavoidable in...

This method has been used for many years, and some shortcomings have been exposed in clinical practice: 1) Due to the influence of the mask on the appearance, the patient's medical compliance is poor, and the proportion of treatment abandonment is high; 2) The prognosis of some patients is not good, and the treatment effect is not significant; 3 ) Relapse is unavoidable for some patients after recovery; 4) Stereovision recovery of patients after recovery is not ideal

But there are still some deficiencies in the liquid crystal glasses that are used for children's amblyopia correction reported in the literature at present: 1) compared with traditional covering method, only improved the outward appearance of treatment glasses, although patient's medical compliance improves to some extent, but with traditional covering method The treatment principle is the same, but the treatment effect is not improved; 2) The specific clinical needs of amblyopia treatment are not fully considered, and the function and mode are too single

However, recent international studies have found that the traditional masking method has obvious defects in principle

It has been reported that the traditional occlusion method can also inhibit the neural pathways of the amblyopic eye while occluding the dominant eye, which violates the above-mentioned theory established by the occlusion method, and destroys the existence basis of binocular vision, which is not conducive to the recovery of binocular vision function and the development of stereoscopic vision.
