Three adults with acquired unilateral visual impairment noticed phosphenes when they heard noises. They witnessed them only when resting in a dark or dimly illuminated room. The hallucinations persisted for days in a postkeratoplasty patient, for weeks in a patient with optic neuritis, and for months in a patient with compression of the optic nerve. The sound-induced phosphenes in these cases seemed to be a pathologic variety of hypnagogic hallucination. We theorize that under conditions of altered excitability and visual deafferentation of the brain, cells capable of responding to both visual and auditory stimuli become hyperresponsive to sounds.
三名获得性单眼视力障碍的成年人在听到噪音时出现了光幻视。他们只有在黑暗或光线昏暗的房间里休息时才会看到。这些幻觉在角膜移植术后患者中持续了数天，在视神经炎患者中持续了数周，在视神经受压患者中持续了数月。这些病例中由声音诱发的光幻视似乎是一种病理性的临睡幻觉。我们推测，在大脑兴奋性改变和视觉传入缺失的情况下，能够对视觉和听觉刺激作出反应的细胞会对声音产生过度反应。
