目前国内采用的内斜视的分类标准中,把两类集合过强性内斜视(非屈光性调节性内斜视和非调节性集合过强型内斜视)都划归高AC/A型内斜视.实际上前一类内斜视的AC/A确实是高出正常范围;后一类的AC/A不高,有的还可能偏低.上述问题是隐斜法导致的错误,改用梯度法检查AC/A之后,就能发现上述错误.前者的病因是调节性集合与调节的比值偏高,或者说调节性集合过强,即高AC/A.后者的病因是接近性集合过强、紧张性神经支配或是其他类型集合过强导致的看近内斜视度数变大,总是称之为非调节性集合过强.只有了解AC/A各种检查方法的本质,才能区别这两类不同病因的内斜视.

There are two types of convergence excess esotropia in the classification of strabismus in our country. One is nonrefravtive accommodative esotropia and another is nonaccommodative convergence excess esotropia. Inadequate heterophoria method to determine the AC/A ratio does not distinguish between a high AC/A ratio and nonaccommodative convergence excess. The diagnosis of nonrefravtive accommodative esotropia is based on the presrnee of a high AC/A ratio as established with the gradient method to distinguish this condition from nonacconunative convergence excess.
