RESUMO
Introducción: El síndrome de Anton-Babinsky es un trastorno neuropsiquiátrico poco frecuente, que se manifiesta por anosognosia y ceguera cortical, debido a lesiones en las áreas visuales asociativas de la corteza occipital sin presentar afectación en la vía visual. En adultos mayores sus manifestaciones clínicas suelen ser atípicas y la valoración geriátrica integral permite orientar el diagnóstico, que se puede asociar con síndromes geriátricos. Objetivo: Describir las manifestaciones clínicas, síndromes geriátricos, paraclínicos y tratamiento de un paciente con Síndrome de Anton-Babinsky. Caso clínico: Paciente de 85 años, quien durante un postoperatorio inmediato de cirugía ocular (pterigión) presentó alteración fluctuante del estado de conciencia, alucinaciones visuales, disminución de la agudeza visual bilateral y anosognosia. La analítica sanguínea no reportó alteraciones y la tomografía computarizada de cráneo documentó isquemia occipital bilateral, se le diagnosticó síndrome de Anton-Babinsky. Conclusiones: El síndrome de Anton-Babinsky puede tener presentación atípica a través de síndromes geriátricos. La valoración geriátrica integral permite realizar un diagnóstico y manejo multicomponente oportuno con el objetivo de influir en el pronóstico tanto a corto como a largo plazo(AU)
Introduction: Anton-Babinski syndrome is a rare neuropsychiatric disorder, with a manifestation of anosognosia and cortical blindness, due to lesions in the associative visual areas of the occipital cortex without presenting visual pathway impairment. In elderly adults, its clinical manifestations are usually atypical and a comprehensive geriatric assessment allows to guide the diagnosis, which can be associated with geriatric syndromes. Objective: To describe the clinical manifestations, geriatric syndromes, paraclinical findings and treatment of a patient with Anton-Babinski syndrome. Clinical case: This is the case of an 85-year-old patient who, during the immediate postoperative period after ocular surgery (pterygium), presented a fluctuating alteration of consciousness, visual hallucinations, decreased bilateral visual acuity and anosognosia. Blood analysis reported no alterations and cranial computed tomography documented bilateral occipital ischemia; the patient was diagnosed with Anton-Babinski syndrome. Conclusions: Anton-Babinski syndrome may have an atypical presentation through geriatric syndromes. Comprehensive geriatric assessment allows for timely multicomponent diagnosis and management with the aim of influencing both short- and long-term prognosis(AU)

PURPOSE: To determine causes of visual impairment in children at the Low Vision Service of the Ophthalmic Clinic at the University of São Paulo and at the Brazilian Association for the Visually Impaired People (Laramara), located in São Paulo, Brazil. PATIENTS AND METHODS: This study evaluated 3,210 visually impaired children (49% female, 51% male; average age, 5.9 years). Visual impairment was present in 57% (visually impaired group) and 43% presented another associated disability (multiple disability group). RESULTS: The main causes of visual impairment in the visually impaired group were toxoplasmic macular retinochoroiditis (20.7%), retinal dystrophies (12.2%), retinopathy of prematurity (11.8%), ocular malformation (11.6%), congenital glaucoma (10.8%), optic atrophy (9.7%), and congenital cataracts (7.1%). The main causes of visual impairment in the multiple disability group were optic atrophy (37.7%), cortical visual impairment (19.7%), toxoplasmic macular retinochoroiditis (8.6%), retinopathy of prematurity (7.6%), ocular malformation (6.8%), congenital cataracts (6.1%), and degenerative disorders of the retina and macula (4.8%). The retina was the most frequently affected anatomic site in the visually impaired group (49.2%) and the optic nerve in the multiple disability group (39%). CONCLUSION: Primary, secondary, and tertiary prevention efforts for childhood blindness and visual rehabilitation must be considered in Latin America.
