Problems solved by technology

Therefore, there are many problems in the existing strabismus inspection, such as non-cooperation of the inspected person, too long inspection time, and inaccurate inspection results.
In addition, the existing inspection methods mainly rely on the experience of the examiner, and the patient's inspection data cannot be digitally archived, which is inconvenient for subsequent patient condition analysis and expert consultation.

Abstract

The invention provides a dynamically adjustable sighting mark device for eyeball movement examination. The device comprises an operation table which comprises a display screen facing a patient and used for displaying a dynamic picture designed based on a visual perception system principle; a camera arranged above the display screen and used for shooting or recording eye images when the patient observes the dynamic pictures on the display screen; a mode key used for switching and displaying eyeball movement examination modes of different dynamic pictures; and a communication unit used for communicating and transmitting the acquired eye images to external equipment for storage and comparative analysis. According to the device, the eye adjusting function of the examined person can be fully aroused in the examination process, the examined person actively participates in the examination, key data in the examination process can be digitally archived, the examination time is saved, and the examination result is more accurate.

Description

technical field [0001] The present application relates to the technical field of strabismus inspection equipment, in particular to a dynamically adjustable optotype device for eye movement inspection. Background technique [0002] An accommodative optotype is an optotype with fine detail that the eye can see clearly through the precise use of accommodation. In various eye movement tests (involving diseases with eye movement disorders such as strabismus or orbital fractures), such as alternating cover tests and cover-to-cover tests, it is necessary to place accommodative optotypes in front of the patient to mobilize the adjustment function of the tested eye . Since eye movement examinations are mainly for young children, the existing accommodative optotypes are mostly static patterns, which are difficult to mobilize the attention of young children. In the actual inspection process, it is usually necessary to replace several different optotypes, and the examinee is repeatedl...
