Topical tropicamide induced delirium and psychosis: case report Delírio e psicose induzidos por tropicamida tópica: relato de caso
Acute psychosis and confusional states are known complications of treatment with anticholinergic agents in the elderly. We report an 87-year-old female patient presenting with acute neurobehavioral abnormalities requiring hospitalization immediately after starting treatment for openangle glaucoma with the topic cycloplegic muscarinic receptor blocker tropicamide. Case-effect relationship was confirmed. The authors make a review of the literature trying to identify the clinical manifestations and risk factors for this complication.<br>Tratamento com drogas anticolinérgicas é uma causa conhecida de alterações agudas do estado mental em idosos. Relata-se o caso de uma paciente de 87 anos de idade com alterações comportamentais agudas, que necessita de internamento imediatamente após início de terapia para glaucoma de ângulo aberto com tropicamida, um agente cicloplégico bloqueador de receptor muscarínico. A relação causa-efeito foi confirmada depois de a droga ter sido reiniciada durante o internamento. É apresentada uma revisão da literatura delineando as manifestações clínicas mais comuns e fatores de risco para essa complicação

Charles Bonnet syndrome in cranio-maxillofacial surgery: case report
BACKGROUND:
Complex visual hallucinations in the presence of a clear mental state and in the absence of underlying neurological disorders have received increased recognition since Charles Bonnet reported visual hallucinations secondary to mature cataracts in 1760. The prevalence of Charles Bonnet syndrome (CBS) varies widely in the literature and might be underestimated in most settings. The current paper presents a case of acute-onset CBS due to a unilateral Frost suture after revision of an orbit floor fracture.
CASE REPORT:
A 68-year-old male patient underwent an operation to repair a unilateral orbital floor fracture and subsequent eye patching by a Frost suture. The patient complained of complex, colored visual hallucinations ∼3 h after waking from general anesthesia. The visual hallucinations stopped during sleep and reappeared in the morning. The symptoms disappeared completely ∼2 h after removal of the Frost suture.
DISCUSSION:
Frost sutures are commonly used in oculoplastic surgery and may result in acute onset of visual hallucinations. CBS is often neglected, and clinicians must be aware of the association between acute visual deprivation and CBS
