«¡¡¡Doctor: yo no estoy loca!!!». Síndrome de Charles Bonnet:a propósito de 3 casos

Resumo

Introduction: Charles Bonnet Syndrome (CBS) is a clinical condition characterized by the presence of visual hallucinations in patients with normal cognitive status associated with significant deterioration of visual function. It is a disorder whose incidence seems to increase in our medical consultations due to increased life expectancy and eye diseases associated to ageing. Case reports: We present the clinical cases of 3 female patients diagnosed with CBS in the Neurophthalmology Unit from 2012 till 2015. Cognitive pathology was discarded by the Psychiatry Service. The mentioned hallucinations were about people, animals or flowers. The associated diseases were advanced diabetic retinopathy, pseudoexfoliative glaucoma, corneal decompensation and macular edema. In two cases this syndrome was associated with treatment with topical brimonidine. Discussion-Conclusions: CBS is a little known syndrome associated with severe visual impairment. Patients are usually attended by the Primary Care or Psychiatric Services, this leading to misdiagnosis and receiving unnecessary treatments. Its complexity thereof requires adequate knowledge and a multidisciplinary approach in order to provide both a correct diagnosis and an appropriate treatment.
