Surgical Treatment of V-pattern Exotropia in Crouzon Syndrome.
PURPOSE Strabismus affects as many as 60% to 70% of patients with Crouzon syndrome. V-pattern strabismus is common and is thought to be secondary to severe oblique muscle dysfunction. The complex motility disorders produced by abnormal extraocular muscles in this syndrome can be difficult to manage. Few studies have reported findings regarding the extraocular muscles or how to plan and adapt th...
متن کاملCrouzon syndrome in association with acanthosis nigricans
Crouzon syndrome is a rare inherited autosomal dominant syndrome characterized by craniosynostosis, midface hypoplasia. Acanthosis nigricans may be associated with Crouzon syndrome, but it differs from the classic crouzon syndrome. This is a report of a 30-year-old-woman who presented acanthosis nigricans coexist with crouzon syndrome.
متن کاملElectromyography of extraocular muscles in Duane's syndrome.
The electromyographic (EMG) study of patients with Duane's retraction syndrome has shown that there is a gross abnormality of innervational pattern in this condition. Most commonly the lateral rectus is affected and shows an innervation differing from the normal in several respects. The first description of the EMG pattern in two patients came from Breinin (I957) when he reported little activit...
متن کاملCrouzon Syndrome: Relationship of Eye Movements to Pattern Strabismus.
PURPOSE To characterize conjugate eye movements in Crouzon syndrome (CS) patients with and without strabismus. METHODS Smooth pursuit, saccades, horizontal optokinetic nystagmus (OKN), and horizontal vestibulo-ocular reflex (VOR) were recorded using binocular video-oculography (VOG) in 10 children with CS (5 orthotropic, 5 strabismic) and 12 age-matched controls. Hess-Lancaster plots were gen...
متن کاملExpression of schizophrenia biomarkers in extraocular muscles from patients with strabismus: an explanation for the link between exotropia and schizophrenia?
Recent studies have implicated exotropia as a risk factor for schizophrenia. We determined whether schizophrenia biomarkers have abnormal levels of expression in extraocular muscles from patients with strabismus and explored whether differences in gene expression between medial and lateral rectus muscles may explain the specific association of schizophrenia with exotropia but not esotropia. Sam...
