ObjectiveTo evaluate the clinical characteristics and surgical outcomes of early-onset exotropia and to compare differences between constant and intermittent exotropia at presentation.MethodsThe medical records of 45 exotropia patients with a reported onset before 1 year of age who were operated on between 2008 and 2011 were reviewed, and the clinical(More)
PURPOSE Using high-resolution magnetic resonance imaging (MRI), we investigated whether rectus pulleys are significantly displaced in superior oblique (SO) palsy and whether displacements account for strabismus patterns. DESIGN Prospective case-control study. PARTICIPANTS Twenty-four patients diagnosed with SO palsy based on atrophy of the SO muscle on(More)
PURPOSE To compare the outcomes of unilateral lateral rectus recession to unilateral recession-resection in the treatment of patients with intermittent exotropia. METHODS The medical records of patients with intermittent exotropia with exodeviation of 20(Δ) to 25(Δ) who underwent unilateral lateral rectus recession or recession-resection at a single(More)
PURPOSE This study employed magnetic resonance imaging (MRI) to investigate possible size and contractility changes in the superior oblique (SO) muscle, and possible isometric hypertrophy in the inferior oblique (IO) muscle, resulting from abnormal mechanical loading in Brown syndrome (BrS). METHODS High resolution orbital MRI was obtained in 4 congenital(More)
PURPOSE To determine whether rectus extraocular muscle (EOM) sizes and pulley locations contribute to exotropia, we used magnetic resonance imaging (MRI) to measure these factors in normal control participants and in patients with concomitant and pattern exotropia. DESIGN Prospective case-control study. PARTICIPANTS Nine patients with concomitant(More)
Purpose We used magnetic resonance imaging (MRI) to ascertain effects of optic nerve (ON) traction in adduction, a phenomenon proposed as neuropathic in primary open-angle glaucoma (POAG). Methods Seventeen patients with POAG and maximal IOP ≤ 20 mm Hg, and 31 controls underwent MRI in central gaze and 20° to 30° abduction and adduction. Optic nerve and(More)
Purpose To investigate changes in volumes of extraocular muscle (EOM) compartments in unilateral superior oblique (SO) palsy using magnetic resonance imaging (MRI). Methods High-resolution, surface-coil MRI was obtained in 19 patients with unilateral SO palsy and 19 age-matched orthotropic control subjects. Rectus EOMs and the SO were divided into two(More)
Idiopathic intracranial hypertension (IIH) is a condition of raised intracranial pressure (ICP) in the absence of space occupying lesions. ICP is usually measured by lumbar puncture and a cerebrospinal fluid (CSF) pressure above 250 mm H2O is one of the diagnostic criteria of IIH. Recently, we have encountered two patients who complained of headaches and(More)
