目的：探讨照相机辅助测量对评估角膜映光法(Hirschberg Test)测定共同性斜视斜视角的准确性。

方法：收集2016-01/2018-01我院收治的105例共同性斜视患者的临床资料，入院后均接受传统Hirschberg Test法、图片Hirschberg Test法斜视角检查，以三棱镜遮盖试验为金标准，记录传统Hirschberg Test法、图片Hirschberg Test法与金标准测定斜视角偏差值，分析Kappa角对偏差值的影响，分析照相机辅助测量在共同性斜视角中的应用价值。

结果：传统Hirschberg Test法、图片Hirschberg Test法、三棱镜遮盖试验测定斜视角比较差异均有统计学意义(P<0.05)，三棱镜遮盖试验测定斜视角度高于图片Hirschberg Test法(P<0.05)，图片Hirschberg Test法又高于传统Hirschberg Test法(P<0.05)，图片Hirschberg Test法与三棱镜遮盖试验测定斜视角一致性高于传统Hirschberg Test法(P<0.05)； 传统Hirschberg Test法测定斜视角偏差值比较差异有统计学意义(P<0.05)，传统Hirschberg Test法偏差值均高于图片Hirschberg Test法(P<0.05)； 图片Hirschberg Test法对阳性、阴性Kappa角患者倾斜度检查偏差度均低于传统Hirschberg Test法(P<0.05)。

结论：照相机辅助测量图片Hirschberg Test法对共同性斜视斜视角测定偏差低于传统Hirschberg Test法，且更适用于无法配合的低龄患者。

METHODS:The clinical data of 105 patients with concomitant strabismus who were admitted to the hospital during the period from January 2016 to January 2018 were collected. After admission, they were given traditional Hirschberg Test and picture Hirschberg Test for squint angle examination.Taking the prism cover test as golden standard, the deviation values between squint angle measured by golden standard and those measured by the traditional Hirschberg Test and the picture Hirschberg Test were recorded.The influence of Kappa angle on the deviation value was analyzed.The application value of camera-assisted measurement in squint angle of concomitant strabismus was analyzed.

RESULTS:There was a significant difference in the value of squint angle measured by traditional Hirschberg Test, picture Hirschberg Test and prism cover test test(P<0.05), and the squint angle measured byprism cover test test was higher than that of picture Hirschberg Test method(P<0.05), and the angle in picture Hirschberg Test method was higher than that in traditional Hirschberg Test method(P<0.05), and the consistency of picture Hirschberg Test method and prism cover test test in measuring squint angle was higher than that of Traditional Hirschberg Test method(P<0.05).There were significant differences in the deviation values of squint angle measured by traditional Hirschberg Test among the 4 examiners(P<0.05).The deviation values of all examiners measured by traditional Hirschberg Test were higher than those by picture Hirschberg Test(P<0.05).The deviation degree of picture Hirschberg Test was lower than that of traditional Hirschberg Test in terms of the examination of squint angle in patients with positive and negative Kappa angle(P<0.05).

CONCLUSION: The deviation of camera-assisted measurement picture Hirschberg Test is lower than that of traditional Hirschberg Test for the measurement of squint angle of concomitant strabismus, and it is more suitable for young patients who cannot cooperate with.
