Application of the quick contrast sensitivity function in visual function assessment / 中华实验眼科杂志

ABSTRACT

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.
