摘要
目的 :评价与眼屈光不正状态可能相关的各项眼调节功能状况 ,探讨眼屈光不正与眼调节之间的相关性。方法 :分别对 4 7名学生 94只眼进行屈光不正、调节幅度、调节灵敏度、调节准确度 (双眼交叉柱镜FCC法 )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 :被检者的屈光不正度平均值为 (- 2 .4 6± 2 .2 8)D ,调节幅度均值为(7.90± 2 .95 )D ,调节灵敏度为 (17.2 8± 4 .92 )次 /min ,调节准确度均值为 (0 .5 8± 0 .6 0 )D ,其中调节幅度与眼屈光度有显著相关性 (r=0 .377,P≤ 0 .0 5 ) ;调节准确度与眼屈光度有显著相关性 (r=- 0 .4 71,P≤ 0 .0 5 )。结论 :眼的屈光不正与眼调节幅度和眼调节滞后量有显著相关 ;眼的调节灵敏度与屈光不正无明显关系。提示我们可通过训练调节幅度和准确度来减缓近视加深。
Objective:To evaluate the status of accommodation and refractive error development. To investigate the correlation between these factors.Methods:Refraction,accommodative amplitude,accommodative ease,and FCC tests were performed on 47 students(94 eyes). Results were analyzed with SPSS software.Results:The results showed that accommodative amplitude was significantly related to refractive error,r=0.377;P=0.004(P≤0.05). Results also showed that the accuracy of accommodation was significantly related to refractive error,r=-0.471;P=0.000(P≤0.05).Conclusion:Refractive error was significantly related to accommodative amplitude and accommodative lag while reading.
