Problems solved by technology

[0004] However, the existing two inspection methods for rotator strabismus are quite different from the real life experience of the patient. Although the patient can swing his head freely during the double Maddox rod inspection, what he sees is lines, not specific objects. Although the patient sees the actual cross picture, the patient can only keep his head still during the examination, and cannot get up and move to observe the surrounding things, which is not conducive to judging the actual strabismus status of the patient

Embodiment 1

[0035] Such as Figure 1 to Figure 7 The shown inspection tester for rotatory strabismus includes a carrier 1 that can be worn on the head and a detection mechanism 2 installed on the carrier 1. The detection mechanism 2 includes a lens barrel 20 and an eyepiece built in the lens barrel 20 21. A display screen 22, a camera 23 and a collimating lens 28, and a power supply system is built in the carriage 1.

[0036]The position of the carrier 1 in front of the corresponding eyes is the mirror frame 10, the lens barrel 20 is slidably connected with the lens frame 10, and there is a locking structure between the lens barrel 20 and the lens frame 10, which can be easily switched by sliding the lens barrel 20 to the left and right An examination of the left eye and an examination of the right eye.

[0037] The mirror frame 10 is also provided with a light-shielding plate 3, and there is a linkage structure between the lens barrel 20 and the light-shielding plate 3. The linkage stru...

Embodiment 2

[0049] like Figure 8 to Figure 10 As shown, the technical content of this embodiment is basically the same as that of Embodiment 1, and the technical points of difference between this embodiment and Embodiment 1 are:

[0050] The imaging system consists of a pair of eyepieces 21 and a pair of display screens 22, two high-speed lenses 6 constitute a picture capture system, and a control system is also provided, wherein one eyepiece 21 and one display screen 22 are used as a group and located in one of the pupils 9 In the front, another group of eyepieces 21 and display screen 22 are located in front of the other pupil 9; the picture capture system adopts high-speed camera technology, and the two high-speed lenses 6 are divided into a left lens 60 and a right lens 61, and the left lens 60 and the right lens 61 are respectively For simulating the field of vision of the left eye and the right eye and capturing images, the images captured by the left lens 60 and the right lens 61 ...

Abstract

The invention discloses an examination tester for rotational strabismus. A detection mechanism can be worn on the head, pictures in front of eyes of a patient are displayed in a display screen in real time through a camera, and the patient can freely observe surrounding things through the display screen and then adjust the rotation of the display screen to make the pictures right; and the rotating strabismus degree of the patient can be obtained by reading the rotating angle value of the screen. The main points of the technical scheme are that the device comprises a carrier and a detection mechanism; the detection mechanism comprises a lens cone, an eyepiece, a display screen and a camera, and a power supply system is arranged in the carrier; the eyepiece is provided with a reference cursor, the eyepiece is rotatably connected with the lens barrel, and the lens barrel is provided with a first adjusting piece for adjusting the rotation angle of the eyepiece; the display screen can display pictures captured by the camera in real time, the display screen is rotationally connected with the lens barrel, the lens barrel is provided with a second adjusting piece used for adjusting the rotation angle of the display screen and an angle mark, and the angle mark is used for obtaining the rotation strabismus degree of the patient.

Description

technical field [0001] The invention relates to the field of ophthalmic inspection instruments, in particular to an inspection tester for rotational strabismus. Background technique [0002] Rotational strabismus is an abnormal rotational eye movement in which one or both eyes rotates and tilts temporally or nasally about their anterior-posterior axis. Rotational strabismus can occur alone or co-occur with other types of strabismus. Pure rotational strabismus is rare, and clinically it often coexists with upstrabismus and hypotropia. This is because the muscles responsible for rotation function are also responsible for vertical function. Excessive superior oblique muscle function leads to internal rotation strabismus, inferior oblique muscle function is too strong to cause external rotation strabismus, inferior oblique muscle function is weakened to cause internal rotation strabismus, and superior oblique muscle function is weakened to cause external rotation strabismus. Th...
