Strabismus tester for ophthalmology department

Abstract

The invention relates to the technical field of ophthalmology instruments, in particular to an ophthalmology strabismus inspection tester which comprises a face limiting device and a strabismus detection device. The strabismus detection devices are symmetrically arranged on the face limiting device; the strabismus detection device comprises a mounting frame, a test lamp group, an eyepiece device, a shielding device, a pupil recognition device and a rotation adjusting device; the mounting frame is fixedly mounted on the face limiting device; the test lamp group is arranged beside the mounting rack, and one end of the test lamp group is fixedly connected with the face limiting device; the rotary adjusting device is fixedly mounted on the mounting frame; the eyepiece device is fixedly mounted at the working end of the rotary adjusting device; the shielding device is fixedly mounted on the eyepiece device; the pupil recognition device is fixedly installed on the installation frame. The strabismus degree can be effectively and accurately detected, and meanwhile the detection cost is saved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic instruments, in particular to a strabismus tester for ophthalmology. Background technique [0002] Strabismus generally includes esotropia, exotropia and upper and lower strabismus, esotropia refers to the inward deviation of the eye position; exotropia refers to the outward deviation of the eye position, which can generally be divided into intermittent and constant exotropia; upper and lower strabismus refers to the upward deviation of the eye position Or downward deviation, less common than esotropia and exotropia, upper and lower strabismus is often accompanied by head tilt, that is, compensatory head position. [0003] In medicine, the degree of strabismus is often used to quantify the degree of strabismus. Accurately detecting the degree of strabismus is beneficial to the subsequent training of strabismus and the design of strabismus surgery. The use of prisms to cover, remove, and alterna...

Problems solved by technology

This detection method has the disadvantages of a large number of prisms or a large array of mirrors, which is extremely inconvenient to use and high in cost.

[0005] In CN201811446141.0, by adjusting the position of the lens to form a prism surface, the volume and cost of the detection equipment can be effectively reduced, but the structure is simple and the detection effect is unstable
