摘要
目的研究混合散光儿童足矫配镜情况下戴镜与不戴镜视近（33em）时的调节反应，为临床正确配戴眼镜提供指导。方法横断面研究。招募54例（54只右眼）经1％阿托品眼膏散瞳验光后确诊为混合散光的5-7岁儿童，应用Shin—NipponNVision—K5001红外线自动验光仪，测量其在阅读距离为33cm时足矫戴镜及不戴镜情况下视近时的调节反应。采用配对t检验对结果进行分析。结果阅读距离为33cm时戴镜及不戴镜调节滞后量分别为（0．64±0．67）D和（0．09±0．59）D，两者差异有统计学意义（t=5．262，P〈0．01）。根据等效球镜度将混合散光分为远视性（〉0．00D）、正视性（0．00D）及近视性（〈0．00D）3种类型，其视近情况下戴镜与不戴镜时调节滞后量分别为（0．52±0．51）D与（0．17±0．53）D（t=2．680，P〈0．05）、（0．75±0．57）D与（0．08±0．74）D（t=4．746，P〈0．01）、（0．73±0．96）D与（-0．07±0．52）D（t=3．011，P〈0．01）。结论混合散光儿童视近时戴镜均表现出明显的调节滞后。
Objective To investigate the changes in accommodative responses at 33 cm of children with mixed astigmatism with and without wearing full corrective spectacles. Methods The right eyes of 54 5-7 year old children with mixed astigmatism were investigated in this cross-sectional study. They were given full corrective spectacles according to the results of optometric testing using 1% atropine eye ointment. An infrared autorefractor （Shin-Nippon Ophthalmic Instruments） was used to measure the accommodative responses of children with and without wearing full corrective spectacles at 33 em （reading distance）. A paired t test was used for analysis. Results The results demonstrated that with glasses or unaided vision the accommodative lag at 33 cm was 0.64±0.67 D and 0.09±0.59 D, respectively, and the difference was statistically significant （t=5.262, P〈0.01）. The data were then divided by spherical equivalent refraction （SER） into 3 groups, SER〉0.00 D, SER=0.00 D, SER〈0.00 D. The respective accommodative lags at 33 cm with or without glasses were 0.52±0.51 D and 0.17±0.53 D （t=2.680, P〈0.05）, 0.75±0.57 D and 0.08±0.74 D （t=4.746, P〈0.01）, and 0.73±0.96 D and -0.07± 0.52 D （t=3.011, P〈0.01）. Conclusion The near accommodative lag might lead to hyperopie retinal blur during near viewing and drive myopia progression.
