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(33 cm)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只有眼)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-Nippon NVision-K5001红外线自动验光仪,测量其在阅读距离为33 cm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33 cm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(＞0.00 D)、正视性(0.00 D)及近视性＜0.00 D)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 rcsponses of children with and without wearing full corrective spectacles at 33 cm (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 hyperopic retinal blur during near viewing and drive myopia progression.
