Using a device based on the Pulfrich effect, we examined 70 patients with various strabismus problems and 20 normal subjects for gross stereopsis. We found an excellent correlation between this dynamic stereopsis test and random dot stereograms. Additionally, in several instances the Pulfrich device was easier to use and interpret correctly than random dot stereograms. The Pulfrich effect can be elicited reliably in patients as young as 3 1/2 years of age. Three patients with anisometropic amblyopia and stereopsis were found to possess a spontaneous Pulfrich effect.
我们使用基于普尔弗里希效应的设备，对70名患有各种斜视问题的患者和20名正常受试者进行了粗略立体视觉检查。我们发现这种动态立体视觉测试与随机点立体图之间存在极佳的相关性。此外，在某些情况下，普尔弗里希设备比随机点立体图更易于使用和正确解读。在年仅3岁半的患者中也能可靠地引发普尔弗里希效应。我们发现3名患有屈光参差性弱视和立体视觉的患者具有自发的普尔弗里希效应。
