摘要
弱视是一种发育紊乱性疾病,我国弱视患者检出率高达2.8%。对弱视视功能进行检查可以帮助医生更准确判定病情,从而制定有效的个性化治疗方案。针对弱视患者存在的视功能缺损模式,采用心理物理学的阈限算法,设计了弱视视功能检查系统。系统软件部分利用VC中的MFC以及Matlab的Psychophysics Toolbox实现视功能检查模块,通过SQL Server建立后台数据库记录检查数据。同时,为了达到心理物理学上对视功能检查的特殊显示要求,硬件部分加入了Vedio Switcher进行输出视频信号的转换。系统经临床实际试用,表明系统稳定性好,能满足弱视视功能检查的特殊临床需要。
Amblyopia is a developmental disorder of the visual system.There are about 2.8% of people in China who have amblyopic disease.The examinations of visual functions for amblyopia can help doctors make better treatment for patients.In this paper, a system with a psychophysics method is introduced to examine different visual functions of amblyopia.For the software system, MFC is used in the user interface and the overall framework.The Psychophysics Toolbox based on Matlab is adopted to realize the model of visual functions examination.SQL Server is used to generate back-end database.Meanwhile, a hybrid programming system between VC＋＋ and Matlab is adopted to combine the entire system into one.For the hardware of the system, a Vedio-Switcher is used to improve the display accuracy to meet the special requirements of the vision test.The results show that this system has good stability and can meet the needs of visual functions examination for amblyopia.
