Hysterical and malingered blindness may be distinguished from organic ocular and cortical blindness by a variety of clinical and electrophysiological tests. This report discusses the limitations of these tests and emphasizes the objective superiority of a new test which utilizes the electronystagmographic technique. This test is based on the principle that visual input blocks nystagmus induced by vestibular stimulations: the presence of nystagmus suppression will indicate that blindness is either hysterical or malingered.
癔症性和诈病性失明可通过多种临床和电生理测试与器质性眼部和皮质性失明相鉴别。本报告讨论了这些测试的局限性，并强调了一种利用眼震电图技术的新测试在客观上的优越性。该测试基于视觉输入会阻断前庭刺激诱发的眼球震颤这一原理：眼球震颤抑制的存在将表明失明是癔症性的或诈病性的。
