One hundred and fifty successive referrals to a psychogeriatrician were assessed for visual hallucinations. Forty-four (29.33 per cent) patients reported visual perceptual disturbances. No differences between hallucinators and non-hallucinators were found in terms of sex, age, length of illness, underlying psychiatric diagnosis or cognitive score. There was a significant correlation between presence of hallucinations and eye pathology (less than .001) and delusions (less than .001). The phenomenological characteristics of the visual hallucinations are analyzed. The "picture" sign is described in 7 patients and the Charles Bonnet syndrome in two. The significance of these findings is discussed.
对连续转诊至一位老年精神科医生处的150名患者进行了视幻觉评估。44名（29.33%）患者报告有视觉感知障碍。在幻觉者和非幻觉者之间，在性别、年龄、病程、潜在精神科诊断或认知评分方面未发现差异。幻觉的存在与眼部病理（小于0.001）和妄想（小于0.001）之间存在显著相关性。对视幻觉的现象学特征进行了分析。7名患者出现了“图像”征，2名患者出现了查尔斯·博内综合征。对这些发现的意义进行了讨论。
