摘要目的 比较随机点整体立体视检测法与Titmus局部立体视检测法在临床中的应用.方法 从天津市以人群为基础的"3～15岁少年儿童斜视、弱视及屈光不正流行病学调查"资料中分层随机抽取正常视力儿童409名.弱视儿童210名;应用<随机点立体视觉检查图>整体立体视检测法和Titmus局部立体视检测法测定立体视锐度,比较正常视力儿童及弱视儿童应用这两种方法的立体视锐度分布.结果 正常视力儿童的中心凹立体视:随机点法为74.3%,Titmus法为86.3%,差异有统计学意义(X~2=18.79,P=0.000);弱视儿童组中心凹立体视分别为38.6%和51.9%,差异有统计学意义(X~2=11.87,P=0.008).弱视儿童立体视盲的检出率分别为12.4%和6.2%(X~2=11.87,P=0.008).结论 正常视力儿童立体视锐度值随机点整体立体视检测法高于Titmus局部立体视检测法,应用随机点整体立体视检测法能更准确地评价弱视患者的立体视功能.

abstractsObjective To study the clinical value of Random-Dot Stereotest (global stereopsis) and Titmus Stereotest (local stereopsis).Methods All cases were randomly selected from "The Epidemiology of 3-15 year old Children with Strabismus,Amblyopia and Refractive Error in Tianjin',including 409 children with normal vision and 210 children with amblyopia.The children's stereopsis was evaluated using Random-Dot Stereograms (RDS) for global stereopsis,and Titmus for local stereopsis.Results from both groups were compared of two forms of the stereopsis distribution of children with normal vision and children with amblyopia.Results The foveal stereopsis of children with normal vision measured with RDS was 74.3%,Titmus 86.3%,and the difference was statistically significant (X~2=18.79,P=0.000).The foveal stereopsis of amblyopic children measured with RDS was 38.6%,Titmus 51.9%,and the difference was statistically significant (X~2=11.87,P=0.008).The detection rate of blindness of stereopsis in amblyopic children with RDS was 12.4%,Titmus 6.2%.Conclusions The stereopsis acuity with RDS is higher than stereopsis acuity with Titmus in children with normal vision,and RDS is better at determining the stereopsis of amblyopic patients.
