About 30% of our patients suffering from purely binocular asthenopia showed lower binocular than monocular visual acuity. Cover test examination revealed exophoria at near fixation, which could be regarded to be physiological. Furthermore, the Pola test as well as Graefe's prism diplopia test showed no pathological findings. When given 4 prism base-in, a better binocular acuity was achieved and exophoria at for distance fixation was revealed. Often the prisms base-in had to be increased slowly and an operative treatment was indicated in 80%. The test is described in detail and examples from typical case studies are demonstrated. The importance of the test for understanding asthenopia in cases with heterophoria is discussed.
在我们患有单纯双眼视疲劳的患者中，约30%的患者双眼视力低于单眼视力。遮盖试验检查显示近注视时存在外隐斜，可认为是生理性的。此外，Pola试验以及格雷费棱镜复视试验均未发现病理性结果。给予4棱镜底向内时，可获得更好的双眼视力，并显示远距离注视时存在外隐斜。通常棱镜底向内度数必须缓慢增加，80%的患者需要手术治疗。本文详细描述了该试验，并展示了典型病例研究的实例。讨论了该试验对于理解斜视性视疲劳病例的重要性。
