| 摘 要： | 目的探讨屈光不正矫正与视网膜调制传递函数测量结果的关系。设计前瞻性非随机自身对照研究。研究对象无其他眼病的单纯性屈光不正者25例50眼。方法受试者首先测量裸眼视力,再分别测量在屈光未矫正、用框架眼镜矫正和用隐形眼镜矫正三种状态下不同干涉条纹视力(0.06、0.1、0.2、0.4、0.6、0.8)的视网膜调制传递函数值(用RM-800视网膜调制传递函数仪)。主要指标视网膜调制传递函数值。结果对于未矫正的屈光不正患者,视力表视力与干涉条纹视力有显著性差异(Z=9.009,P=0.000);对于矫正后的单纯性屈光不正患者,视力表视力与干涉条纹视力无显著性差异(Z=1.009,P=0.317);在屈光未矫正、用框架眼镜矫正和用隐形眼镜矫正三种状态下测得的视网膜调制传递函数值的差异有统计学意义(P﹤0.05),且戴隐形眼镜矫正所测得值略高于戴框架眼镜所测得值。结论干涉条纹视力比视力表视力更能准确反映视网膜-大脑的视觉功能;屈光未矫正进行视网膜调制传递函数的测量将可能出现假阳性,建议测量视网膜调制传递函数时要矫正屈光不正。 |

| Abstract: | Objective To study the relationship between retinal modulation transfer function(MTF) and ametropia correction.Design A prospective non-randomized self-controlled study.Participants 50 eyes of 25 ametropia patients without other eye diseases.Methods Vision was exammed when these 50 eyes without any correction.Then retinal MTF was determined by RM-800 MTF testing instrument when these 50 eyes were uncorrected,corrected with glasses and corrected with contact lenses,respectively.The retinal MTF was got at six... |
