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

Efficacy, durability, and safety of intravitreal faricimab with extended dosing up to every 16 weeks in patients with diabetic macular oedema (YOSEMITE and RHINE): two randomised, double-masked, phase 3 trials

Background: To reduce treatment burden and optimise patient outcomes in diabetic macular oedema, we present 1-year results from two phase 3 trials of faricimab, a novel angiopoietin-2 and vascular endothelial growth factor-A bispecific antibody. Methods: YOSEMITE and RHINE were randomised, double-masked, non-inferiority trials across 353 sites worldwide. Adults with vision loss due to centre-involving diabetic macular oedema were randomly assigned (1:1:1) to intravitreal faricimab 6·0 mg every 8 weeks, faricimab 6·0 mg per personalised treatment interval (PTI), or aflibercept 2·0 mg every 8 weeks up to week 100. PTI dosing intervals were extended, maintained, or reduced (every 4 weeks up to every 16 weeks) based on disease activity at active dosing visits. The primary endpoint was mean change in best-corrected visual acuity at 1 year, averaged over weeks 48, 52, and 56. Efficacy analyses included the intention-to-treat population (non-inferiority margin 4 Early Treatment Diabetic Retinopathy Study [ETDRS] letters); safety analyses included patients with at least one dose of study treatment. These trials are registered with ClinicalTrials.gov (YOSEMITE NCT03622580 and RHINE NCT03622593). Findings: 3247 patients were screened for eligibility in YOSEMITE (n=1532) and RHINE (n=1715). After exclusions, 940 patients were enrolled into YOSEMITE between Sept 5, 2018, and Sept 19, 2019, and 951 patients were enrolled into RHINE between Oct 9, 2018, and Sept 20, 2019. These 1891 patients were randomly assigned to faricimab every 8 weeks (YOSEMITE n=315, RHINE n=317), faricimab PTI (n=313, n=319), or aflibercept every 8 weeks (n=312, n=315). Non-inferiority for the primary endpoint was achieved with faricimab every 8 weeks (adjusted mean vs aflibercept every 8 weeks in YOSEMITE 10·7 ETDRS letters [97·52% CI 9·4 to 12·0] vs 10·9 ETDRS letters [9·6 to 12·2], difference −0·2 ETDRS letters [−2·0 to 1·6]; RHINE 11·8 ETDRS letters [10·6 to 13·0] vs 10·3 ETDRS letters [9·1 to 11·4] letters, difference 1·5 ETDRS letters [−0·1 to 3·2]) and faricimab PTI (YOSEMITE 11·6 ETDRS letters [10·3 to 12·9], difference 0·7 ETDRS letters [−1·1 to 2·5]; RHINE 10·8 ETDRS letters [9·6 to 11·9], difference 0·5 ETDRS letters [−1·1 to 2·1]). Incidence of ocular adverse events was comparable between faricimab every 8 weeks (YOSEMITE n=98 [31%], RHINE n=137 [43%]), faricimab PTI (n=106 [34%], n=119 [37%]), and aflibercept every 8 weeks (n=102 [33%], n=113 [36%]). Interpretation: Robust vision gains and anatomical improvements with faricimab were achieved with adjustable dosing up to every 16 weeks, demonstrating the potential for faricimab to extend the durability of treatment for patients with diabetic macular oedema.
