Diagnostic apparatus for intelligent screening of strabismus and diopter

Abstract

The invention discloses a diagnostic apparatus for intelligent screening of strabismus and diopter. The diagnostic apparatus comprises an optical system and a processing control unit, the optical system includes a strabismus imaging optical path and a diopter imaging optical path, the two optical paths share an infrared camera and a light source, the infrared camera and the light source are arranged on an arc guide rail with synchronous movement, the infrared camera is moved to the right front of the eye to detect the diopter or the light source is moved to the right front of the eye to detect strabismus, the strabismus imaging optical path further includes a visual mark and a grating and visual mark switching structure, the visual mark is solely and fixedly arranged between the grating and visual mark switching structure and the light source, and eye shielding and sight-to-sight switching can be intelligently completed by the grating and visual mark switching structure without additional manual operation; the processing control unit includes an SOC processor, a wireless communication module, a touch screen and a power supply, and the SOC processor is connected with the wireless communication module, the touch screen, the power supply and the optical system respectively; the diagnostic apparatus can diagnose the strabismus and diopter intelligently.

Description

technical field [0001] The invention relates to a medical ophthalmic optoelectronic instrument, in particular to an intelligent diagnostic device for screening strabismus and diopter, which is used for strabismus screening and diopter detection. Background technique [0002] Children under the age of 7 are in the critical and sensitive period of visual function development. Only in a good visual environment can the visual function develop normally; in early childhood, various types of strabismus, refractive error and other diseases are prone to occur If it is not discovered early, it will often affect the normal development of children's vision and show poor vision; among them, strabismus is a common ophthalmic disease, which not only affects the appearance, but also has a serious impact on the binocular vision function and physical and mental health of the patient. Therefore, early screening can be used as an important means to discover children's eye diseases and visual pr...

Problems solved by technology

Specifically, at present, hospitals mostly use manual methods for strabismus examination: staring at 33cm optotype, 6m optotype with Mitsubishi mirror inspection, outdoor optotype, and cover test to measure the degree of strabismus, but the above traditional detection methods exist. The following disadvantages: (1) Due to the fast eye movement during the inspection, professional ophthalmologists or optometrists need to carefully observe and confirm the diagnosis repeatedly, which is time-consuming and labor-intensive; (2) Covering method needs to cover the eyes multiple times and test repeatedly , there are differences in the time to manually cover the eyes, which will ultimately affect the test results; (3) The detected data is manually recorded, which may make mistakes, which will ultimately affect the diagnostic results

[0004] In addition, most of the current ophthalmological testing and diagnostic instruments can only perform strabismus screening, or can only detect diopter. If multiple ophthalmological vision items are required to be tested, multiple separate testing instruments must be used. very inconvenient and cost more
