We examined 310 schoolchildren to determine what normal values might be expected for successive convergence and divergence ocular movements. Vergence facility may affect the efficiency of visual information processing. The population consisted of children in grades 1 through 8. The subjects wore anaglyph glasses and viewed a nonvariable square-X-circle anaglyph target alternately through a 16 delta base-out and 4 delta base-in prism flipper. The subjects were directed to keep the target "clear and single." The total number of vergence cycles was recorded for 1 min. Students in higher grade levels were able to complete more vergence changes than students in beginning grades. The average number of changes accomplished per minute at each age level is presented for this population.
我们检查了310名学童，以确定连续的集合和散开眼球运动的正常数值可能是多少。集合功能可能会影响视觉信息处理的效率。研究对象包括1至8年级的学生。受试者佩戴立体眼镜，通过一个16棱镜度底向外和4棱镜度底向内的翻转棱镜交替观察一个固定的方形-X-圆形立体视标。要求受试者保持视标“清晰且单一”。记录1分钟内集合循环的总数。高年级学生比低年级学生能够完成更多的集合变化。本文给出了该人群每个年龄组每分钟完成的平均变化次数。
