摘　　要：目的探讨外斜v征患者眼底客观旋转状态与v征程度及下斜肌功能变化的关系。方法临床病例回顾性研究。于2014年10月至2015年1月在天津市眼科医院就诊的外斜V征患者50例，用三棱镜交替遮盖法测量v征程度，检查双眼运动，评估下斜肌亢进程度，行眼底照相，测量视盘黄斑夹角（fovea—discangle，FDA）。眼底客观旋转度与V征程度的相关度采用Pearson相关分析，眼底客观旋转度与下斜肌亢进程度的相关度采用Spearman相关分析。结果外斜v征患者双眼平均FDA与V征程度之间相关系数r=0．244，P=0．088，无显著相关性。下斜肌亢进为88只眼，其中亢进＋1为38只眼（-14．39±7．01）°，亢进＋2为36只眼（-8．96±7．16）°，亢进＋3为12只眼（-13．83±6．94）°，亢进＋4为2只眼（-9．50±0．71）°。FDA与下斜肌亢进程度之间的相关系数r=-0．075，P=0．605，无显著相关性。结论外斜v征患者眼球旋转程度并不决定v征的程度，也不影响下斜肌亢进的程度，眼球旋转更像是V征发生后的-个伴随现象。Objective To investigate the correlation between the status of ocular torsion, the de- gree of V sign, and the inferior oblique muscle function in V pattern exotropia patients. Methods Fifty cases of v pattern exotropia were studied. The degree of V sign was measured with the meth- od of prism and alternative cover. The ocular movement, assess the degree of inferior oblique mus- cle hyperfi.mction were checked, the fovea-disc angle （FDA） by fundus photograph were measured. Pearson method was used to analysis the correlation between the degree of objective ocular torsion and the degree of the V sign. Spearman method was used to analyze the correlation between the de- gree of objective ocular torsion and the inferior oblique muscle hyperfunction. Results There was no significant correlation between the average FDA and the degree of the V sign （r =0.244, P = 0.088）. There were 88 eyes with inferior oblique muscle hyperfunction： 38 eyes （-14.39±7.01）° with hyperfunction ＋1, 36 eyes （-8.96°±7.16）°hyperfunction ＋2, 12 eyes （-13.83±6.94）° hyperfunction ＋3, and 2 eyes （-9.50±0.71）°hyperfunction ＋4. There was no significant correlation between the average FDA and the degree of inferior oblique muscle hyperfimction （r =-0.075, P =0.605）. Conclusions The ocular torsion in V pattern exotropia patients does not determine the degree of the V sign, also does not influence the degree of inferior oblique muscle hyperfunction. It is more like an accompany- ing phenomenon after the V sign.
