摘要:
目的:根据眼外肌协同运动的原理,并结合双眼前红蓝分视眼镜通过计算机扑捉眼球运动轨迹,分析眼位和眼外肌力量用简便的方法精确测量眼位和眼球运动,并设计出简便用于临床检测的眼位追踪定位系统的软、硬件结合的创新发明设备并对共同性外斜斜视度检测。方法:通过运用诊断眼位进行同向运动视标追踪,通过计算机获取图像分析转动方向有无一眼落后或过度,何眼出现偏斜,斜度是否一致等。采用红蓝视镜,令患者双眼分视,观察眼球运动及协调情况。查50例共同性斜视患者(其中20例间歇外斜患者),用传统方法(角膜映光法、三棱镜遮盖法、视野弧检查法、同视机检查法等)检测患者斜视度。将计算机测定结果与传统斜视角测量值(以视野弧检查法为主要参考标准)进行统计学分析。结果:1) 通过设备可以方便采集患者九方位运动图像。2) 双眼协调力量检查可以明确诊断麻痹性眼外肌的情况。3) 共同性斜视(间歇性外斜视患者除外)患者50例计算机眼外肌诊断系统检测斜视角与视野弧测得视近斜视角相比,有显著性差异(P < 0.05),但二者差值均数绝对值 < 5 (提示计算机眼外肌诊断系统检测的斜视角结果与视野弧斜视角检查结果相差5度范围以内)。4) 间歇外斜视患者20例,通过红蓝眼镜分视检查的斜视度数与视野弧测的视近斜视角比较有显著性差异(P < 0.05),二者差值均数绝对值 < 5 (提示计算机眼外肌诊断系统检测的斜视角结果与视野弧斜视角检查结果相差5度范围以内)。结论:采用计算机眼外肌诊断系统分析眼外肌力量对麻痹性斜视的眼外肌力量判断准确,通过红蓝分视镜对测量共同性斜视(包括间歇性外斜视)患者斜视角检测结果比较准确。

Abstract: Objective: To invent a new measurement method, we innovate an eye tracking positioning system, which combines software and hardware equipment to capture eye movements, analyzes extra ocu-lar muscle strength with the red and blue glasses, and compares with the common strabismus de-gree examinations according to the extra ocular muscle cooperative movement principle. Methods: We utilized the standard tracking eye direction system and conducted computer image analysis, which could also measure the extra ocular muscles movement and coordination. With the red and blue glasses, it can make the patients separate both eye views. 50 cases of concomitant strabismus patients (including 20 cases of intermittent exotropia strabismus) were included in this study. We compared the traditional methods (including the corneal light reflection method, prism covering method, visual arc inspection method and synoptophore method) with the new instrument for the strabismus degree detection by statistical analysis. Results: 1) Our new innovation device can easily acquire eye movement image of nine standard directions. 2) Binocular coordination test can defini-tively diagnose patients’ paralysis extra ocular muscle. 3) 50 cases of concomitant strabismus (ex-cept the intermittent exotropia patients) had utilized this new system to detect the angle and com-pare with the angle measurement from visual arc method. There is a significant difference (P < 0.05), yet the difference between the two means are smaller than 5 arc degrees meaning the new system generates acceptable results compared with those from the conventional method. 4) 20 cases with intermittent exotropia had been measured with the red and blue glasses supporting system compared with the traditional visual arc measurement. According to the finding, there is a significant difference (P < 0.05), yet the difference between the two means is smaller than 5 arc degrees meaning the new system generates acceptable results compared with those from the conventional method. Conclusion: The new computer system is an accurate system on the extra ocular muscle strength diagnosis, especially in the judgment of paralytic strabismus. Also, the squint angle detection result is accurate in concomitant strabismus (including intermittent exotropia) by using the red and blue glasses.
