Abstract

The present invention belongs to the field of ophthalmic medical equipment and is one strabismus measuring device and method. The strabismus measuring device of the present invention includes a head fixing unit an eye video camera, a system calibrator, a stared target, a light source and a computerized image analysis system. The strabismus measuring instrument designed based on the present invention can measure strabismus fast, precisely and objectively.

Description

technical field [0001] The invention belongs to the field of ophthalmic medical instruments, in particular to a strabismus measuring instrument and a measuring method thereof. Background technique [0002] Strabismus is a common disease in ophthalmology, and surgical treatment is its main method. The main basis for the preoperative design of strabismus surgery is the degree of strabismus. Therefore, obtaining an accurate degree of strabismus is an important factor affecting the surgical effect. Existing clinically widely used methods for checking the degree of strabismus mainly include: prism plus cover test method, visual field arc test method, corneal light reflection method, strabismus ruler test method and synoptic machine test method. The above methods all depend on the patient’s understanding and cooperation to varying degrees, and due to the influence of the subjective factors of the examiner and the examinee, the examination results are often inconsistent and have la...
