The effect of visual skills, such as binocularity, on saccadic eye movement test performance is currently unknown. Therefore, the relationship between performance on commonly used clinical saccadic eye movement tests and visual skill was studied in a masked investigation of 181 kindergartners and first graders (mean age 6.25 years) from a middle class, suburban, elementary school near Cleveland, Ohio. The New York State Optometric Association King-Devick saccade test (NYSOA K-D) and the Developmental Eye Movement test (DEM) were employed because they are two commonly used clinical saccadic eye movement tests. A Modified Clinical Technique (MCT) vision screening and Randot stereoacuity test were performed to evaluate other visual skills. Analysis revealed that for the whole study population, total errors on the NYSOA K-D were significantly related to referral on the MCT screening (p = 0.015) and stereoacuity worse than 100 sec arc (p = 0.011). A trend toward significance was also found between DEM ratio and stereoacuity worse than 50 sec arc for the whole study population. However, in the children who passed the MCT, stereoacuity was not found to be significantly related to performance on NYSOA K-D or DEM. Thus, our findings indicate that visual difficulties may affect performance on the NYSOA K-D in this population.
目前尚不清楚诸如双眼视等视觉技能对眼跳运动测试表现的影响。因此，在一项针对俄亥俄州克利夫兰附近郊区一所中产阶级小学的181名幼儿园儿童和一年级学生（平均年龄6.25岁）的盲法调查中，研究了常用临床眼跳运动测试的表现与视觉技能之间的关系。采用了纽约州验光协会金 - 德维克眼跳测试（NYSOA K - D）和发育性眼动测试（DEM），因为它们是两种常用的临床眼跳运动测试。进行了改良临床技术（MCT）视力筛查和兰多立体视锐度测试以评估其他视觉技能。分析显示，对于整个研究人群，NYSOA K - D上的总错误与MCT筛查中的转诊显著相关（p = 0.015），并且立体视锐度差于100秒弧度时也显著相关（p = 0.011）。对于整个研究人群，在DEM比率与立体视锐度差于50秒弧度之间也发现了显著趋势。然而，在通过MCT的儿童中，未发现立体视锐度与NYSOA K - D或DEM的表现有显著关系。因此，我们的研究结果表明，视觉困难可能会影响该人群在NYSOA K - D上的表现。
