PURPOSE
To describe three cases of Charles Bonnet syndrome (CBS) in glaucoma patients with preserved visual acuity.
METHODS
Three glaucoma patients who had taken part in a recent CBS study were interviewed about their hallucinations. The patients underwent macular optical coherence tomography (OCT) of both eyes. The visual function was evaluated with visual field measurement (Humphrey visual field analyser) and visual acuity testing (Snellen scale).
RESULTS
All three patients had preserved visual acuity (≥0.5 in both eyes) and at least one eye with advanced visual field defect (Mean Deviation worse than -12.00 decibel). They all reported vivid visual hallucinations with insight into the unreal nature of the hallucinations.
CONCLUSION
Charles Bonnet syndrome can occur in glaucoma despite preserved visual acuity. Awareness of this relation is desirable among clinicians, as it will improve communication with patients.
目的
描述 3 例伴有视力保留的青光眼患者的 Charles Bonnet 综合征（CBS）。
方法
对最近参与 CBS 研究的 3 例青光眼患者进行访谈，了解其幻觉情况。对所有患者进行双眼黄斑光学相干断层扫描（OCT）。通过视野测量（Humphrey 视野分析仪）和视力测试（Snellen 视力表）评估视觉功能。
结果
所有 3 例患者均具有保留的视力（双眼均≥0.5），至少有一眼存在晚期视野缺损（平均偏差值差于-12.00 分贝）。他们均报告了生动的视觉幻觉，并对幻觉的不真实性有洞察力。
结论
尽管视力保留，青光眼仍可发生 Charles Bonnet 综合征。临床医生应该意识到这种关系，因为这将改善与患者的沟通。
