目的检测双眼在不同颜色光下的调节幅度的大小,比较其差异及与屈光度的相关关系.方法横断面研究.受检者91例(182眼),年龄15～30岁,平均(22.9±4.2)岁.所有受检者均进行规范的主觉验光,根据屈光度分为正视组、低中度近视组、高度近视组.分别在白光(440、560、610 nm混合光)、红光(610 nm)和绿光(560 nm)下,用近视标负镜片法检测双眼的调节幅度.数据采用单因素方差分析、配对t检验和Pearson相关分析.结果 ①总体182眼在不同颜色光下调节幅度差异有显著统计学意义(F=21.490,P＜0.01),白色光下调节幅度[(13.04±2.75)D]最大,绿光[(12.40±2.61)D]次之,红光[(11.26±2.53)D]最小.②3种颜色光下正视组、低中度近视组、高度近视组间调节幅度差异有统计学意义(F=21.476、14.356、16.540,P＜0.01),正视组最低,高度近视组最高;正视组在不同光下调节幅度的差异无统计学意义(F=1.930,P＞0.05),其余两组差异有统计学意义(F=15.684、11.821,P＜0.01).③3种光下调节幅度均与近视屈光度呈正相关(r=0.385、0.312、0.328,P均＜0.01).④同一个体近视屈光度较高眼调节幅度较大,红光下差异无统计学意义(t=-1.803,P＞0.05),白光、绿光下差异有统计学意义(t=-2.344、-2.474,P＜0.05).结论不同颜色光所诱导的调节幅度的高低是不同的,绿光下检测到人眼调节幅度大于红光,近视组差异明显;调节幅度与屈光度显著相关,近视度较高者具有较大的调节幅度.

Objective To measure the binocular accommodative amplitude under different monochromatic lights; to evaluate the differences in accommodative amplitude under different monochromatic lights and the correlation between refractive state and accommodative amplitude.Methods This was a cross-sectional study.Ninety-one subjects (182 eyes),aged 15～30 years (average 22.9±4.2 years) were enrolled in the study.All subjects underwent refractive examinations measured with MPMVA,amplitude of accommodation measured with a minus lens-stimulated test under white light (440 nm,560 nm,610 nm combined light),red light (610 nm) and green light (560 nm).A one-way ANOVA and Pearson correlation were used for statistical analysis.Results ①There were significant differences in the amplitude of accommodation under different lights (F=21.49,P＜0.01):the largest amplitude was under white light (13.04±2.75 D),green light (12.4±2.61 D) was second,and red light (11.26±2.53 D) was the lowest.②The amplitude of accommodation under the 3 hights was significantly different (F=21.476,14.356,16.540,P＜0.01) among emmetropes,low and moderate myopes and high myopes.The smallest amplitude was for emmetropes and the amplitude was for high myopes.The amplitudes of accommodation were not significantly different for emmetropes under different lights (F=1.93,P＞0.05) while the other two groups showed significant differences (F=15.684,11.821,P＜0.01).③There was a positive correlation between the amplitude of accommodation and refraction (r=0.385,0.312,0.328,P＜0.01).④For each individual,the accommodative amplitude was higher with a higher degree of myopia,under red hight,the differences were not significant (t=-1.803,P＜0.05),under white and green lights,the differences were significant (t=-2.344,2.474,P＜0.05).Conclusion The amplitude of accommodation differs when induced by different lights.It is higher with green light than red light,and there was a significant difference in myopes.The amplitude of accommodation is correlated with refractive error; the higher the degree of myopia,the larger the amplitude of accommodation.
