A red/green anaglyph stereotest (TNO) was administered to a group of patients who had anisometropic amblyopia, and the Worth 4-Dot test for fusion to two groups of strabismus patients. Both tests were administered twice, with the red/green lens position of the glasses reversed between eyes for the second administration. Twelve of 15 patients with anisometropic amblyopia exhibited a stereo acuity difference of 2:1 or more, and 18 of 89 strabismic patients changed Worth 4-Dot fusion or suppression status, between the two positions of the glasses. A group of seven strabismic patients who showed the reversal effect on the Worth 4-Dot test had the results of one glass' position discrepant with those of a geometrically identical achromatic test. It appears that the red/green format can introduce artifacts in binocular vision testing. Testing twice, with the red/green glasses reversed between trials, will prevent misinterpretation of binocular status and may provide diagnostically useful information.
对一组屈光参差性弱视患者进行了红/绿互补色立体视测试（TNO），并对两组斜视患者进行了用于融合检测的Worth 4点测试。两项测试均进行了两次，第二次测试时眼镜的红/绿镜片位置在两眼之间颠倒。15例屈光参差性弱视患者中有12例表现出立体视锐度差异为2:1或更大，89例斜视患者中有18例在眼镜的两个位置之间改变了Worth 4点融合或抑制状态。一组7例在Worth 4点测试中表现出反转效应的斜视患者，其一个眼镜位置的结果与几何形状相同的消色差测试结果不一致。似乎红/绿格式在双眼视觉测试中可能会引入伪像。在两次测试之间颠倒红/绿眼镜进行两次测试，将防止对双眼状态的错误解读，并可能提供具有诊断价值的信息。
