青年人近视眼与各调节因素的关系

Analysis of the relationship between accommodation factors and myopia

目的分析眼屈光不正与调节各因素的关系，探讨近视眼与眼调节之间的相关性。方法分别对45名大学生的90眼进行屈光不正、调节幅度、调节灵活度和正相对调节检查，然后将各项结果与屈光不正状况进行相关性统计分析。结果45名大学生受试者调节幅度的平均值为（8．49±1．61）D（6．25～13．70D）。调节灵活度平均值为（9．64±2．30）周／min。正相对调节平均值为（-2．19±0．84）D。其中调节幅度与眼屈光度有显著相关性（r=-0．885，P≤0．05）。调节灵活度与眼屈光度无相关性。结论眼屈光不正与眼调节幅度有显著关系，眼的调节灵活度与屈光不正无相关关系。

Objective To investigate the correlation between accommodaton and refractive error.Methods Forty-five students （90 eyes） were randomly chosen for the study. Refraction, accommodative amplitude, accommodative facility and positive relative accommodation tests were performed on the students. Results were analyzed with SPSS software. Results The value of accommodative amplitude was （8.49± 1.61）D, the value of accommodative facility was （9.64 ± 2.30）cycle/min, the value of related positive accommodation was （ - 2.19 ± 0.84）D. The results showed that accommodative amplitude was significantly correlated to refractive error（ r = - 0. 885, P 〈0.05）. The results also showed that accommodative facility was not correlated to refractive error （ r = 0. 132, P = 0.215）, but there was a correlation between positive relative accommodation and refractive error （ r = - 0.503, P ≤〈0.05）. Conclusion Refractive error is significantly correlated to accommodative amplitude and positive relative accommodation, but it is not correlated to accommodative facility.
