A new use of nonstereoscopic cues in stereopsis testing is described. It consists of alternation of fixation while observing for image jump in the disparate portions of the test target. This may enable some stereoblind strabismus patients to achieve artifactually good stereotest scores and explain those patients who appear to have gross stereopsis on the Titmus test, but are unable to perform any random-dot test of stereopsis. A new stereotest is described which does not resort to a random-dot format and yet is free from lateral displacement and alternation cues.
本文描述了非立体视觉线索在立体视觉测试中的一种新用途。它包括在观察测试目标的不同部分的图像跳跃时交替注视。这可能使一些立体盲斜视患者在立体视觉测试中获得虚假的良好分数，并解释了那些在Titmus测试中似乎有明显立体视觉，但无法进行任何随机点立体视觉测试的患者。本文还描述了一种新的立体视觉测试方法，该方法不采用随机点格式，且没有横向位移和交替线索。
