Strabismus training device

Abstract

The invention provides a strabismus training device. The strabismus training device is characterized by comprising a display module, an image shooting and processing module, a calibration module, an eye movement point calculation module and a strabismus training image displacement range calculation module, or a strabismus training prism degree range calculation module, wherein the image shooting and processing module includes at least one camera, and can continuously shoot images of the left eye and the right eye; and the calibration module is used for performing single-eye calibration on the left eye and the right eye. The strabismus training device has the beneficial effects: on the basis of keeping fusion of both eyes, the strabismus degree is gradually reduced by performing visual training on a strabismus patient, and the effect of treating strabismus without an operation is achieved.

Description

technical field [0001] The invention relates to the field of ophthalmic medical devices, in particular to a strabismus training device. Background technique [0002] Strabismus is a common disease in ophthalmology. The treatment of strabismus is mainly surgical treatment and visual training at present. Generally speaking, patients with strabismus can try visual training first. If they can return to normal through visual training, the physical and mental pain caused by surgery can be avoided, and the possible side effects of surgery can also be avoided. [0003] The traditional vision training method is generally to wear prisms for binocular vision training, but the choice of prism degree in vision training is currently difficult. Because if the vision training prism degree is equal to the strabismus prism degree, although the patient feels relatively comfortable subjectively, the eye muscles maintain a large strabismus state, and it is not easy to change the strabismus deg...

Problems solved by technology

[0003] The traditional vision training method is generally to wear prisms for binocular vision training, but there are currently difficulties in the selection of prism degrees during vision training

Because if the vision training prism degree is equal to the strabismus prism degree, although the patient feels relatively comfortable subjectively, the eye muscles maintain a large strabismus state, and it is not easy to change the strabismus degree through training, resulting in poor training effect; and if the vision training prism degree is greater than If the prism degree of strabismus is too small, close to the limit of binocular vision vergence, the patient will feel very uncomfortable and prone to visual fatigue, which will have an adverse effect on the training effect; even if the vision training prism exceeds the limit of binocular vision vergence , which destroys the state of fusion, will lead to patients with diplopia or confusion, which can not achieve effective visual training effect
