在视觉通路中,从视神经末梢至最高中枢的任何水平的病变均可出现视幻觉。与原发性眼疾有关的视幻觉一般不会发生,或仅为简单的闪光;而较复杂的视幻觉与大脑脚、大脑半球或视交叉等部位的病变有关。本文报告3例继发于眼疾使视力逐渐丧失而自发地出现视幻觉的病人。 In visual pathways, visual hallucinations may occur at any level of the lesion from the optic nerve end to the highest center. Visual hallucinations associated with primary eye diseases generally do not occur or are simply flash; more complex hallucinations are associated with lesions in the brain’s foot, hemisphere, or optic chiasm. This article reports 3 patients who spontaneously develop visual hallucinations secondary to eye disease that causes loss of vision.
