应用Humphrey视野分析仪和细微矩阵方法测定了14例正常人,以中心凹为中心,1°空间间隔,由100个位点构成的9°×9°矩阵的蓝光明视和暗视阈值,并应用此方法研究了屈光效应。结果表明,在明视情况下,黄斑区的平均敏感度改变小于1,0dB,而在暗视情况下,旁中心4°的敏感性较中心凹升高15.0dB。由1.00D屈光度所致非聚焦效应使敏感度下降近1.2dB。此项技术对黄斑视功能测定提供了一种高空间分辨的敏感的方法。
The Humphrey visual field analyzer and the subtle matrix method were used to determine the Blu-ray and dark-thresholding thresholds of 9 normal persons in a 9 ° × 9 ° matrix composed of 100 sites with the fovea as the center, 1 ° space interval and Refractive effects were studied using this method. The results showed that in the case of bright vision, macular area the average sensitivity of less than 1,0dB change, while in the dark case, the center 4 ° sensitivity than the fovea elevation of 15.0dB. The non-focusing effect caused by the 1.00D diopter decreased the sensitivity by nearly 1.2dB. This technique provides a highly sensitive and sensitive method for macular visualization.
