Frenzel's spectacles have been essential tools for the clinical examination of the vestibular system since 1925. However, they may lead to false-negative results because they enable the patient to fixate, or to false-positive results because they induce pseudospontaneous nystagmus. Both pitfalls originate from direct illumination of the patient's eyes, and we propose a new design using indirect illumination.
自1925年以来，弗伦泽尔眼镜一直是前庭系统临床检查的重要工具。然而，它们可能会导致假阴性结果，因为它们使患者能够注视，或者导致假阳性结果，因为它们会诱发假性自发性眼球震颤。这两个陷阱都源于对患者眼睛的直接照明，我们提出了一种使用间接照明的新设计。
