屈光不正对视网膜对比敏感度的影响

【摘要】 目的探讨屈光不正对视网膜对比敏感度检测的影响。方法使用RM-800对比敏感度仪测量47例中低度近视94眼在屈光矫正与不矫正状态下进行不同空间频率1.8,3,6,12,18和24cpd(cycles per degree)的视网膜对比敏感度的测量。结果屈光不矫正状态下视网膜对比敏感度在所有检查频段均较对照组下降(P﹤0.05)。结论屈光不正对视网膜对比敏感度的测量有明显影响。更多还原

【Abstract】 Objective To evaluate the influence of ametropia on retinal contrast sensitivity function Methods retinal Contrast sensitivity in patients with myopia were determined in 94 eyes of 47 patients.Retinal contrast sensitivity was assessed with RM-800 contrast testing instrument(which was used to evaluate the visual function from retina to brain),testing for six spatial frequencies,1.8,3,6,12,18and 24 cycles per degree (cpd).Results Contrast sensitivity was significantly worse at all frequencies compared with correct in myopia without correction(P<0.05 respectively).Conclusion Ametropia affect the retinal contrast sensitivity.更多还原
