视网膜周边部屈光不正测量方法探讨

Investigation of peripheral retina refractive error measurement methods

摘要:

目的：比较不同视网膜周边部屈光不正测量方法的可重复性和一致性。

方法：检查者分别使用带状检影镜、Shin-Nippon K5001电脑验光仪和Aberrometor(COAS)像差仪测量28位受试者的中央及周边屈光度。

结果：等效球镜度“M”的测量值在COAS像差仪和电脑验光仪上的可重复性良好(平均差异均 ≤±0.10D)，但检影验光的可重复性较差； 电脑验光仪和COAS像差仪的测量值之间有良好的一致性。

结论：COAS像差仪和Shin-Nippon K5 001电脑验光仪均可作为视网膜中央区和周边部屈光不正测量工具使用。

Abstract:

AIM: To compare the repeatability and agreement between different instruments on peripheral retina refractive error measurement.

METHODS: Streak retinoscopy, Shin-Nippon K5001 Auto-refractor and Aberrometor(COAS)were used to measure 28 participants' central and peripheral retinal field refractive errors.

RESULTS: Spherical equivalent value(M)were repeatable on Aberrometor and Shin-Nippon K5001 Auto-refractor(mean difference≤±0.10D),with poor repeatability on streak retinoscopy. There were good agreement between Aberrometor and Shin-Nippon K5001 Auto-refractor measurements.

CONCLUSION: Aberrometor and Shin-Nippon K5001 Auto-refractor both are valid tools for the central and peripheral refractive error measurement.
