Amblyopia correction and detection device

Abstract

The invention relates to a medical apparatus for correcting and detecting amblyopia, in particular to an amblyopia correction and detection device based on double-eye balance principle. The device comprises two liquid crystal lenses, a main plate, two optical sensors and a control system, wherein the two liquid crystal lenses are embedded on a lens framework, the main plate is fixedly arranged on the lens framework, the two optical sensors are respectively arranged at the inside surfaces of the two liquid crystal lenses, the control system consists of a remote controller which is performed with wireless communication with the main plate, the main plate is provided with a microprocessor, a wireless receiver, a storage card module, a real-time clock and a mode selection switch, the wireless receiver, the storage card module, the real-time clock and the mode selection switch are in communication connection with the microprocessor respectively, the two liquid crystal lenses are in control connection with the microprocessor on the main plate respectively, and the two optical sensors are in communication connection with the microprocessor on the main plate respectively. The device has the advantages that the multi-mode amblyopia therapy and correction training is realized, and the therapy and correction training modes can be freely adjusted according to the disease rehabilitation state of patients; the device is matched with the refraction collection and therapy, so the better amblyopia correction and binocular vision improvement effects are realized.

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 poor, and the treatment effect is not significant; 3) Recurrence is unavoidable in some...

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 poor, and the treatment effect is not significant; 3) Relapse is unavoidable for some patients; 4) The recovery of stereopsis in patients after recovery is unsatisfactory

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.
