对比敏感度函数(CSF)是在不同空间频率下对空间视觉进行基础描述的视觉心理物理学检查方法,为视功能的评估奠定了基础,在基础和临床工作中有很重要的应用,但是过长的检测时间使其缺乏对视功能评估的简便性和广泛性.快速对比敏感度函数(qCSF)是一种新的快速测量CSF的自适应心理物理学程序,它极大地提高了CSF的检测效率.在正常视功能群体、弱视患者以及近视患者等视功能低下患者群体中,qCSF检测结果的高敏感度、高精密度和高重测信度均已得到证实.大样本水平研究也证实qCSF提高了CSF检测效率并降低了花费.目前,qCSF已实现在iPad设备上的应用,运用此程序的临床医疗设备也已在美国、德国的一些临床机构中应用,在临床应用中具有很好的发展前景,因此,本文就qCSF在视功评估中的应用进展进行综述.“,”The contrast sensitivity function (CSF) describes visual sensitivity at different contrasts and spatial scales,which provides a fundamental caracterization of spatial vision,important for basic and clinical applications,but its long testing time has prevented the easy and widespread assessment.The quick contrast sensitivity function (qCSF) method is a novel Bayesian adaptive procedure for rapid measurement of the CSF,which can greatly improve the efficiency of CSF assessment.In the normal eyes,amblyopia,myopia and a low vision population,the high sensitivity,high precision and high test-retest reliability of the qCSF method have been verified.The qCSF method also shows higher CSF efficiency and lower costs in a large sample.Currently,the qCSF method has been implemented on iPad,and medical devices using this program have also been applied in some clinical institutions in the United States and Germany,which has a good prospect in clinical application.In this review,the application of the qCSF in visual function assessment was reviewed.
