Embodiment

[0027] The present invention uses a digital camera or a video camera to take pictures or videos of the checked strabismus patients. The patient can be hugged by his parents or relatives, and the operator only needs a few seconds to obtain special images of strabismus patients. During this process, patients can take photos or videos obtained by digital cameras or video cameras at a relatively long distance without using special postures, and use software to cut and edit images as needed to obtain useful information. With the help of specific software, dynamic and static understanding of compensatory head position, eye movement disorders. Then, through the correlation between the corneal light spot and the degree of strabismus studied by the inventor, and the mathematical model established by advanced mathematical methods, the relationship between the position of the light spot and the degree of strabismus is quantified. The obtained results are automatically analyzed by comput...

Abstract

A strabismus degree measurer for children is disclosed. Its application includes obtaing the photo or video record of patient or the real-time special image taken by the measurer, editing the image to obtain useful data, automatic analyzing by software, calculating to obtain the type and degree of strabismus, and providing the therapeutic scheme.

Description

Technical field: [0001] The invention belongs to the field of ophthalmic medical instruments, in particular to a children's strabismus degree measuring instrument and a using method thereof. Background technique: [0002] It is generally believed that patients with early strabismus should be treated as soon as possible, so as not to affect the development of their vision, especially the formation of stereoscopic vision. Domestic Hao Yushi believes that children aged 2 to 3 are "dead spots" for strabismus inspection, and any subjective functional inspection is difficult to carry out. If the operation is not performed early, the abnormal reflex may develop and become more serious. Therefore, the operation should be performed as soon as possible to strive for the development of binocular vision after the operation. It has been reported abroad that the age of surgery for congenital strabismus has been advanced to six months after birth. [0003] On the other hand, many strabis...
