Herpes Zoster oftálmico e posterior acidente vascular cerebral: relato de caso

Um caso de acidente vascular cerebral (AVC) 14 semanas após a instalação de herpes zoster oftálmico (HZO) é apresentado. A tomografia computadorizada craniana documentou comprometimento em território de artéria cerebral média ipsilateral ao HZO. O diagnóstico de probabilidade é o de arterite por herpes zoster com posterior trombose. Os autores reviram a literatura e enfatizam o longo intervalo entre o HZO e a instalação da hemiplegia. Citam as novas drogas antivirais que tornam esta causa de AVC potencialmente passível de ser prevenida

Ocular, Neurologic and Systemic Findings of the Cases with Optic Nerve Hypoplasia

AIM: To describe the associated ocular, neurologic, and systemic findings in a population of children with optic nerve hypoplasia (ONH) and to evaluate the relationship between ocular signs and neurologic findings. METHOD: A retrospective chart review of 53 patients with the diagnosis of ONH seen between December 1998 and September 2012 was performed. All neurodevelopmental anomalies, neuroradiologic findings, endocrinologic and systemic findings were recorded. Poor vision was defined as the visual acuity poorer than logMAR 1.0 or inadequate central steady maintained fixation. RESULTS: Thirty (56.6%) of the 53 children with ONH were boys. Mean age at presentation was 56.2±46.8 months (range; 3 months to 18 years). Poor vision defined for the purpose of this study was found in 47.2% of 53 patients. Thirty-three (62.3%) children had nystagmus. Thirty-four (64.2%) children had strabismus. Thirteen (38.2%) of those with strabismus had esotropia, 20 (58.8%) had exotropia. The total number of the children with neurodevelopmental deficit was 22 (41.5%) in our study. CONCLUSION: The vision of young children with ONH should be monitored at least annually, and any refractive errors should be treated. Neuroimaging of the brain and endocrinologic evaluation is necessary in all cases with ONH
