方法：共同性内、外斜视患者145例，年龄2～50岁，术前均用三棱镜、视野弧法检查斜视度，根据检查结果及眼轴长度设计手术量，评估斜视术后眼位正位率。

结果：在共同性内、外斜视轻度、重度组中，远、近距离三棱镜与视野弧法所测的斜视度，经统计检验差异均有显著性(P<0.05)； 而在中度斜视组，两种方法所查斜视度经检验差异无显著性(P>0.05)； 共同性内、外斜视组眼轴长度比较差异有显著性(P<0.05)。斜视术后共同性内、外斜视组功能治愈率分别为70.83%，67.01%； 临床治愈率分别为20.84%，24.74%； 无效分别为8.33%，8.25%。

结论：三棱镜、视野弧两种检查法在斜视度检查中应相互补充，同时参考眼轴长度，有利于提高斜视术后眼位正位率降低二次手术的风险。

METHODS: A total of 145 patients with concomitant esotropia or exotropia, aging 2～50 years old, were included. They were examined by PACT and perimeter strabismometry before operation. The strabismic operations were performed, the orthotropia rate of postoperation was assessed.

RESULTS: Using PACT and perimeter strabismometry, there was a significantly difference of deviating angle(P<0.05)in mild and severe strabismic group. But there was no significantly difference of deviating angle(P>0.05)in moderate strabismic group. The functional cure rate of postoperation was respectively 70.83%, 67.01%; the clinical cure rate was 20.84%, 24.74%; invalid rate was 8.33%, 8.25%.

CONCLUSION: The application of PACT and perimeter strabismometry in strabismic operation design, referring to the eye axial length, this can be helpful of improving the cure rate postoperation and decreasing the danger of reopreation.
