To characterize the nature and frequency of Charles Bonnet syndrome in glaucoma patients with low vision.
All patients attending the glaucoma clinic during a period of 10 months who had visual acuity of 20/80 or less in both eyes were included in this study. Each patient was questioned about the occurrence of visual hallucinations. Those who responded positively had a thorough interview relating to the characteristics of the hallucinations. Medical history and social history were taken, followed by a complete ocular examination.
Eighty-nine patients met the inclusion criteria. Eleven patients (12.3%), eight men and three women, admitted to having experienced visual hallucinations. Except for one case, the patients did not disclose this experience previously. Eight patients had one repeatable hallucination, and three patients experienced more than one sight. The visions were usually sharp, and the figures were occasionally incomplete. Most hallucinations were chromatic. Frequency of hallucinations varied between daily and weekly, and duration was mostly a few minutes. In addition to glaucoma, nine of the eleven patients had other ocular findings that could have contributed to the reduction of vision.
Visual hallucinations are not rare in glaucoma patients with low vision. Patients tend to conceal their experience of visual hallucinations, but a discussion of these phenomena with the patient and assurance of their harmless nature will reduce his or her anxiety and concerns.
明确低视力青光眼患者中查尔斯·博内综合征的性质和发生率。
本研究纳入了在10个月期间就诊于青光眼门诊、双眼视力均为20/80或更低的所有患者。询问每位患者是否出现视幻觉。那些回答为阳性的患者就幻觉的特征接受了全面访谈。记录病史和社会史，随后进行完整的眼部检查。
89例患者符合纳入标准。11例患者（12.3%），8名男性和3名女性，承认有过视幻觉经历。除1例患者外，其余患者此前均未透露过这一经历。8例患者有1种可重复出现的幻觉，3例患者经历过不止一种幻视。幻视通常很清晰，图像偶尔不完整。大多数幻觉是彩色的。幻觉出现的频率从每天到每周不等，持续时间大多为几分钟。除青光眼外，11例患者中有9例有其他可能导致视力下降的眼部表现。
低视力青光眼患者中视幻觉并不罕见。患者往往会隐瞒他们的视幻觉经历，但与患者讨论这些现象并保证其无害性将减轻患者的焦虑和担忧。
