    Cese paradójico de un caso de síndrome de Charles Bonnet
    (Archivos de la Sociedad Española de Oftalmología, 2014) Santos Bueso, Enrique Miguel; Serrador García, Mercedes; Sáenz Francés, Federico; Méndez Hernández, Carmen Dora; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; García Sánchez, Julián
    Caso clínico: paciente varón de 78 años diagnosticado de síndrome de Charles Bonnet (SCB) por déficit visual secundario a glaucoma terminal. Evolucionó a amaurosis, presentando desaparición brusca de las alucinaciones de forma paralela a la pérdida del resto visual. Discusión: el cese paradójico del SCB se produce cuando el paciente pierde el resto visual, evolucionando a amaurosis. La falta de estimulación en la retina y el córtex correspondiente hacen desaparecer las alucinaciones debido a que las neuronas desaferentadas e hiperexcitadas pierden el estímulo que desencadena el SCB.

    (Archivos de la Sociedad Española de Oftalmología, 2017) Santos Bueso, Enrique Miguel; Serrador García, Mercedes; Sáenz Francés, Federico; Méndez Hernández, Carmen Dora; Morales Fernández, Laura; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; Porta-Etessam, Jesús
    Case report: The case is presented of a 12 year-old boy with congenital glaucoma and low visual acuity diagnosed with Charles Bonnet syndrome. This consisted of the acute onset of complex, repetitive, persistent, and with visual hallucinations (people, brooms and coffeemakers) of self-limited evolution without treatment. The patient was diagnosed with congenital glaucoma at 3 years of age, and subjected to a trabeculectomy in right eye, and trabeculectomy and keratoplasty in his left eye. Discussion: Charles Bonnet syndrome symptoms have been described in adults, but their presence in children is poorly reflected in literature, with unknown characteristics and prevalence.

    Prevalence and clinical characteristics of Charles Bonnet syndrome in Madrid, Spain
    (European Journal of Ophthalmology, 2014) Santos Bueso, Enrique Miguel; Sáenz Francés, Federico; Serrador García, Mercedes; Porta Etessam, Jesús; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; García Sánchez, Julián
    Purpose: Charles Bonnet syndrome (CBS) is a condition characterized by development of visual hallucinations in patients with no cognitive impairment and significant loss of vision mainly caused by age-related macular degeneration (AMD) or glaucoma. Methods: This was a study of prevalence and characteristics of CBS diagnosed at the Neuroophthalmic Unit within the Ophthalmology Department of Hospital Clínico San Carlos (HCSC), Madrid, Spain. Results: The CBS prevalence in patients from HCSC Madrid is 0.47%, rising to 15% in patients with low vision. Women over 80 years of age comprised 58.3% of the patients, who mainly had AMD (58.3%). Main characteristics of hallucinations included animals (50%), color (58.3%), moving (75%), 6- to 12-month evolution (50%), three times a day frequency (75%), and 3- to 5-minute duration (50%). Conclusions: Charles Bonnet syndrome is a complex process that must be treated jointly by ophthalmologists, neurologists, and psychiatrists in order to ensure accurate diagnosis and adequate management. New studies are needed in order to improve awareness of clinical manifestation of this condition, the incidence of which is underestimated due to patients' fear of being branded mentally ill, as well as physicians' lack of knowledge about CBS.
