Description

사시 자동측정기구Isometric Automatic Measuring Instrument
본 발명은 안구의 사시를 측정하기 위한 기구로서, 보다 상세하게는 안구의 변위를 객관적으로 측정함으로써 양안의 사시에 대한 정도를 각각 정확하게 판단할 수 있는 사시 자동 측정기구에 관한 것이다. The present invention relates to a device for measuring the strabismus of the eye, and more particularly, to an automatic strabismus measuring mechanism capable of accurately determining the degree of strabismus of both eyes by objectively measuring the displacement of the eye.
사시란 두 눈이 정렬되지 않고 서로 다른 지점을 바라보는 상태로, 한쪽 눈으로 정면을 주시하고 있을 때 다른 쪽 눈은 안쪽 또는 바깥쪽으로 이동하거나, 위 또는 아래로 이동하여 안구변위가 일어나는 상태를 말한다. Strabismus is a condition in which two eyes are not aligned and look at different points, and when one eye is looking straight ahead, the other eye moves inward or outward, or moves up or down, causing eye displacement. .
상기한 바와 같은 사시 증상 중 잠복사시(간혈사시 또는 사위)는, 양측 눈으로 동시에 응시 할 때는 안구의 변위가 일어나지 않고, 한쪽 눈을 차폐하여 두 눈의 융합을 방해하게 되면 변위가 나타나는 사시이다. 즉 잠복사시는, 평소에는 안구 변위가 일어나지 않지만, 피로하거나 두 눈의 융합이 방해되는 상황이 나타낼 때 안구변위가 발생하여 증상을 호소하게 된다. Among the above-mentioned strabismus symptoms, latent esotropia (hepatic hemorrhage or son-in-law), when staring simultaneously with both eyes, does not cause displacement of the eye. to be. That is, during latent radiation, eye displacement does not occur normally, but eye displacement occurs when fatigue or disturbance of binocular fusion appears, causing symptoms.
따라서, 사시는 여러 상황에 따라 다양하게 나타나므로 사시의 증상을 정확하게 판단하기 위해서는 상황에 따른 안구의 변위 정도를 정확하게 측정하는 것이 중요하다.Therefore, since strabismus appears in various situations, it is important to accurately measure the degree of displacement of the eye according to the situation in order to accurately determine the symptoms of strabismus.
일반적으로 안구의 변위 정도인 사시각의 측정방법으로는 교대프리즘 가림 검사법이 사용되고 있다. 하지만 상기한 바와 같은 교대프리즘 가림 검사법은 검사자의 경험과 주관적인 판단에 의존하는 방법으로, 검사자에 따라 측정값의 차이가 비교적 크게 나타날 수 있어 정확하고 객관적인 진단이 어렵다는 문제점이 있다.In general, the alternate prism masking test is used to measure the angle of deviation, the degree of eyeball displacement. However, as described above, the alternate prism obstruction test method depends on the experience and subjective judgment of the examiner, and there is a problem in that accurate and objective diagnosis is difficult because the difference in the measured value may be relatively large depending on the examiner.
상기한 바와 같은 문제점을 해소하기 위하여 컴퓨터기반의 영상 처리를 이용하여 안구 변위 정도를 객관적으로 측정하는 개발이 진행되고 있다. 종래의 사시 측정 기구에 관한 기술로는 대한민국 등록특허 10-0949743호가 개시되어 있다.In order to solve the above problems, the development of the objective measurement of eyeball displacement using computer-based image processing is in progress.

상기한 바와 같이 상기 차폐제어장치(400)는 LCD 유리로 구성되어, 상기 좌측차폐유리(400a) 및 상기 우측차폐유리(400b)를 투명 및 불투명으로 제어함으로써, 상기 양안을 각각 차폐하는 것이 바람직하지만 이에 한정하는 것은 아니며, 상기 관통홀(112h) 사이를 이동하며, 상기 관통홀(112h)의 일부를 선택적으로 차폐하는 차단막으로 구성시킬 수도 있다. 즉 상기 차폐제어장치(400)는 좌측안구 및 우측안구를 각각 선택적으로 차폐할 수 있는 다른 형태로 용이하게 변경하여 적용시킬 수 있을 것이다.As described above, the shielding control device 400 is composed of LCD glass, and by controlling the left shielding glass 400a and the right shielding glass 400b to be transparent and opaque, it is preferable to shield both eyes, respectively. The present invention is not limited thereto, and may be configured as a blocking film that moves between the through holes 112h and selectively shields a part of the through holes 112h. That is, the shielding control device 400 may be easily changed and applied to other forms that can selectively shield the left eye and the right eye, respectively.
상기 차폐제어장치(400)는 차폐제어방법(S410)을 이용하여 상기 양안을 선택적으로 차폐할 수 있다. 도 4를 참조하여 상기 차폐제어방법(S410)을 살펴보면, 상기 차폐제어방법(S410)은, 1차 해리단계(S411)와 2차 해리단계(S412)를 포함할 수 있다.The shielding control device 400 may selectively shield both eyes by using a shielding control method (S410). Referring to FIG. 4, the shielding control method S410 may include a primary dissociation step S411 and a secondary dissociation step S412.
상기 1차 해리단계(S411)는, 좌측안구를 기 설정된 시간동안 차폐한다. 상기 1차 해리단계(S411)는 좌측안구를 차폐함으로써, 양안을 해리시킨다. 즉 상기 1차 해리단계(S411)는, 상기 좌측차폐유리(400a)를 불투명하도록 제어하고, 상기 우측차폐유리(400b)는 투명하도록 제어하여 상기 좌측안구만을 차폐할 수 있다. 상기 1차 해리단계(S411)에 의하여 상기 좌측안구는, 우측안구와 해리되어 안구변위가 발생한다. 이때 우측안구는 상기 프레임(100)의 전방에 있는 대상물을 주시하게 되어 움직임이 발생하지 않는다.In the first dissociation step (S411), the left eye is shielded for a preset time. The primary dissociation step (S411) is to dissociate both eyes by shielding the left eye. That is, in the first dissociation step S411, the left shielding glass 400a may be controlled to be opaque, and the right shielding glass 400b may be controlled to be transparent to shield only the left eye. By the primary dissociation step (S411), the left eye is dissociated from the right eye and eyeball displacement occurs. At this time, the right eye gazes at the object in front of the frame 100 so that no movement occurs.
상기 2차 해리단계(S412)는, 상기 1차 해리단계(S411)로부터 좌측안구의 이동을 인식하면, 우측안구를 기 설정된 시간동안 차폐한다. 상기 2차 해리단계(S412)는 우측안구를 차폐함으로써, 양안을 해리시킨다. 즉 상기 2차 해리단계(S412)는, 상기 우측차폐유리(400b)를 불투명하도록 제어하고, 상기 좌측차폐유리(400a)는 투명하도록 제어함으로써 상기 우측안구만을 차폐할 수 있다. 상기 2차 해리단계(S412)에 의하여 상기 우측안구는, 좌측안구와 해리되어 안구변위가 발생한다. 이때 좌측안구는 상기 프레임(100)의 전방에 있는 대상물을 재주시하기 위하여 상기 1차 해리단계(S411)에서 안구변위가 발생한 만큼 이동한 후, 움직임이 발생하지 않는다. The second dissociation step (S412), when recognizing the movement of the left eye from the first dissociation step (S411), shields the right eye for a predetermined time. The secondary dissociation step (S412) dissociates both eyes by shielding the right eye. That is, in the secondary dissociation step S412, the right shielding glass 400b may be opaque and the left shielding glass 400a may be transparent to shield only the right eyeball. By the second dissociation step (S412), the right eye is dissociated from the left eye to generate eye displacement. At this time, the left eye moves after the eyeball displacement occurs in the first dissociation step (S411) in order to replay the object in front of the frame 100, and no movement occurs.
상기 2차 해리단계(S412)로부터 차폐된 우측안구의 이동을 인식하면, 다시 상기 1차 해리단계(S411)를 반복하여 수행한다. 즉 좌측안구를 기 설정된 시간동안 다시 차폐한다. 이에 따라 상기 우측안구는 상기 프레임(100)의 전방에 있는 대상물을 재주시하기 위하여 상기 2차 해리단계(S412)로부터 안구변위가 발생한 만큼 이동하게 된다. Recognizing the movement of the right eye shielded from the secondary dissociation step (S412), the primary dissociation step (S411) is repeated again. That is, the left eye is shielded again for a preset time. Accordingly, the right eye is moved as much as the eye displacement occurs from the secondary dissociation step (S412) in order to replay the object in front of the frame 100.
즉, 상기 1차 해리단계(S411)와 상기 2차 해리단계(S412)는 양안을 해리시켜 선택적으로 안구변위의 발생을 확인하기 위한 것으로, 사시 측정의 목적에 따라 반복하여 수행할 수 있다. That is, the first dissociation step (S411) and the second dissociation step (S412) are for confirming the occurrence of eyeball displacement by dissociating both eyes, and may be repeatedly performed according to the purpose of strabismus measurement.
