Charles Bonnet syndrome is commonly encountered and diagnosed in low-vision patients. It can be distressing for some of them, as there is no known effective treatment of this condition. Although there is a growing interest in retinal implants for blind patients with severe retinal diseases, the effect of these devices on Charles Bonnet syndrome visual hallucinations remains undocumented.
The aim of this study was to report changes in the Charles Bonnet syndrome of a patient with retinitis pigmentosa after implantation of the Argus II retinal prosthesis.
A 65-year-old patient with retinitis pigmentosa and no light perception was frequently experiencing Charles Bonnet syndrome. In the hope of improving his vision, he received an Argus II retinal prosthesis in 2018 and participated in a 10-week rehabilitation program at the Institut Nazareth et Louis-Braille. The nature and the frequency of his Charles Bonnet syndrome were documented with the Questionnaire de repérage du syndrome de Charles Bonnet (a French questionnaire used to screen for Charles Bonnet syndrome) before the surgery and for 70 weeks after it. The patient's visual acuity and visual fields were monitored during the same period. Additional tests were administered to document the visual, psychological, and cognitive states of the patient throughout the study.
Although this case report confirmed that Argus II retinal prosthesis improves the performance of blind patients in visual tests, the improvement was not associated with a decrease in the symptoms of Charles Bonnet syndrome.
Charles Bonnet 综合征在低视力患者中很常见，也易于诊断。对于一些患者来说，这种疾病无法治愈，这可能会带来困扰。尽管人们对严重视网膜疾病致盲患者的视网膜植入物越来越感兴趣，但这些设备对视幻觉 Charles Bonnet 综合征的影响仍无文献记载。
本研究旨在报告接受 Argus II 视网膜假体植入后，一位色素性视网膜炎患者的 Charles Bonnet 综合征的变化。
一位 65 岁的色素性视网膜炎患者无光感，经常出现 Charles Bonnet 综合征。为了改善视力，他于 2018 年接受了 Argus II 视网膜假体植入，并在 Institut Nazareth et Louis-Braille 参加了为期 10 周的康复计划。在手术前和手术后 70 周，使用 Questionnaire de repérage du syndrome de Charles Bonnet（一种用于筛查 Charles Bonnet 综合征的法国问卷）记录他的 Charles Bonnet 综合征的性质和频率。在此期间，监测了患者的视力和视野。进行了额外的测试，以记录患者在整个研究过程中的视觉、心理和认知状态。
尽管本病例报告证实 Argus II 视网膜假体可提高盲患者在视觉测试中的表现，但改善与 Charles Bonnet 综合征症状的减轻无关。
