摘　　要：目的研究间歇性外斜视患者的调节功能与隐斜性近视漂移的关系。方法临床病例对照研究。对2007年7月至2012年7月在江山市中医院眼科就诊的年龄在21～38岁的成人间歇性外斜视组患者56例；正常对照组40例，用MEM（Monocular Estimate Method）动态检影的方法测量注视40cm处调节视标时主导眼的调节反应、正／负相对调节（Positive Relative Accommodation，PRA／Negativerelative Accommodation，NRA）及与之相对应的隐斜性近视。用SPSSl2．0统计软件包进行统计学分析两组间关系。结果间歇性外斜视组患者64．29％（36／56）主导眼表现为调节超前，平均调节反应为（一0．22±0．77）D，与之相对应的隐斜性近视漂移为（一1．22±0．27）D；正常对照组调节反应为（＋O．38±0．38）D，近视漂移为（一0．42±0．27）D，间歇性外斜视组主导眼的调节反应与对照组间差异有统计学意义（t=5．89，P=0．00，P〈0．05）；调节反应量与斜视度之间差异有统计学意义（r=一0．71，P=0．00，P〈0．05）。间歇性外斜视组PRA平均为（一3．93±0．79）D，对照组为（一3．11±0．69）D，两组间差异有统计学意义（t=5．95，P=0．00，P〈0．05）；间歇性外斜视组NRA平均为（＋1．91~0．58）D，对照组为（＋2．28±0．31）D，间歇性外斜视组隐斜性近视漂移为（一1．22±0．27）D，对照组近视漂移为（一0．42±0．27）D，两组间差异有统计学意义（t=一2．81，P=0．01，P〈0．05）。结论间歇性外斜视患者在注视近距离视标时表现为调节超前，调节功能与隐斜性近视漂移密切相关。Objective To study the relationship between the accommodative function and phoria myopia in patients with intermittent exotropia. Methods A total of 756 patients at age 20 to 38 years old with intermittent exotropia and 50 normal controls were recruited. Accommodative response in dominant eye was examined using MEM （Monocular Estimate Method） dynamic retinoscopy, Posi- tive Relative Accommodation/Negative Relative Accommodation （PRA /NRA） to 40cm target with bin- ocular viewing, deviation. The data were analyzed using SPSS12.0 system. Results 64.29% domi- nant eyes showed an accommodative lead. The mean accommodative response was in patients and normal control dominant eye was （-0.22±0.77）D and （＋0.38±0.38）D. The phoria myopia was （-1.22± 0.27）D and （-0.42±0.27）D. There was significant difference between dominant eye in patients and in normal controls （t =5.89, P =0.00） in accommodative response and （t =-2.81, P =0.01） in phoria my- opia. Accommodative response in dominant eye was significantly correlated with the angle of exotro- pia （r =-0.71, P =0.00）. The mean PRA was （＋1.91±0.58）D in patients and （-3.11±0.69）D in normal controls （t =5.95, P =0.00）. The mean NRA was （＋1.91±0.58）D in patients and （＋2.28±0.31）D in nor- mal controls （t =-2.82, P 〈0.01）. Conclusions Accommodative response in patients with intermittent exotropia is lead. The accommodative response is related with the phoria myopia.
