摘　　要：目的分析间歇性外斜视斜视角与辐辏各因素的关系，探讨间歇性外斜视斜视角与辐辏参数的相关性。方法对48例不同程度的间歇性外斜视患者根据斜视角的大小分二三组，分别进行斜视角、正负融合范同、正负聚散幅度、辐辏近点、调节性辐辏与调节的比值检查，将各项检查结果与间歇性外斜视斜视角进行相关性统计学分析。结果48例间歇性外斜视5m远距离斜视角的平均值为（-13．19±8．40）^△，33om近距离平均值（-18．79±6．80）^△。正融合范围平均值7．29±4．73，负融合范围平均值：-4．28±4．55。辐辏近点平均值：破裂点7．50±2．43，恢复点8．74±2．84。远正相对聚散幅度平均值：模糊点12．34±6．90，破裂点18．48±7．63，恢复点10．76±7．19；远负相对聚散幅度平均值：模糊点14．30±6．22，破裂点21．52±6．94，恢复点8．34±7．92。近正相对聚散幅度平均值：模糊点18．03±8．16，破裂点28．13±7．85，恢复点20．25±18．70；近负相对聚散幅度平均值：模糊点14．21±7．04，破裂点21．55±6．96，恢复点8．06±7．99。调节性辐辏与调节的比值平均值：1．89±1．03。负融合功能和负相对聚散幅度与间歇性外斜视斜视角差异有统计学意义（P〈0．01）。结论间歇性外斜视斜视角与负融合功能和负相对聚散幅度有显著相关性，正融合功能范围、正相对聚散幅度、辐辏近点、调节性辐辏与调节的比值与间歇性外斜视斜视角差异无统计学意义。Objective To investigate the relationship between Strabismus Angle and Convergence Parameters of intermittent exotropia. Methods Based on the size of strabismus angle, 48 intermit-tent exotropia patients with different strabismus angle degrees were enrolled and divided into 3 groups. Respectively, strabismus angle, positive and negative fusion range, positive and negative fu- sional vergence, near point of convergence and AC/A rate were collected. Statistical analysis of these test results and the strabismus angle of intermittent exotropia were performed. All statistical cor-relation analyses were performed using SPSS15.0 software. Results The average strabismus angle de-gree of 48 intermittent exotropia patients at 5m distance：-13.19±8.40^△ average at 33cm dis-tance： -18.79±6.80^△ Intermittent Exotropia average： 7.29±4.73, Negative Fusion Range average： -4.28± 4.55, Near Point Of Convergence average： Break Point： 7.50±2.43, Recovery Point： 8.74±2.84. Far Positive Fusional Vergence average： Blur point： 12.34 ± 6.90, Break Point： 18.48 ± 7.63, Recovery Point： 10.76±7.19; Far Negative Fusional Vergence average： Blur point： 14.30±6.22, Break Point： 21.52±6.94, Recovery Point： 8.34±7.92, Near Positive Fusional Vergence average： Blur point： 18.03± 8.16, Break Point： 28.13±7.85, Recovery Point： 20.254-18.70; Near Negative Fusional Vergence aver-age： Blur point： 14.21±7.04, Break age： 1.89±1.03. Only negative fusion Point： 21.55±6.96, Recovery Point： 8 and Negative Fusional Vergence had 06±7.99, AC/A Rate aver-a negative correlation with Strabismus Angle in Intermittent Exotropia, the difference was significant （P 〈0.01）. Conclusions In Intermittent Exotropia, there are significant differences between Strabismus Angle with Negative Fu-sion and Negative Fusional Vergence; and there are no significant differences between Strabismus An-gle with Positive Fusion Range, PoSitive Fusional Vergence, Near Point Of Convergence, AC/A Rate.
