一种基于PL原理的儿童视力检查系统软件

The PL Theory-based Children Visual Acuity Testing Software

优先注视法(preferential looking,PL)是定量测定婴幼儿视力的主要方法。基于PL原理的儿童视力检查系统软件应用计算机数据库技术、图像处理技术和多媒体技术,能够自动生成测试图案,智能判断并形成视力检查结果,为临床儿童视力的检查以及检查数据的管理提供了极大便利。

The preferential looking （PL） is the main method of quantitative test of children visual acuity. This paper presents a PL theory-based testing software to assist doctors to complete children visual acuity testing. The software provides much more convenience both for clinical children visual acuity testing and testing results management. The basic theory and the main functions of the software are illustrated in detail in this paper. And furthermore, this paper points out the features and the innovation of the software. The clinical application of the software is presented by some tables in the end of the paper.
