To probe the mechanism of visual suppression, we have raised macaques with strabismus by disinserting the medial rectus muscle in each eye at 1 mo of age. Typically, this operation produces a comitant, alternating exotropia with normal acuity in each eye. Here we describe an unusual occurrence: the development of severe amblyopia in one eye of a monkey after induction of exotropia. Shortly afte...

PURPOSE To elucidate the genetic or environmental background for clinical features in the three major types of comitant strabismus. METHODS Interview based on a questionnaire asking background factors such as family history of strabismus and abnormalities in pregnancy and delivery was conducted with 101 consecutive patients with infantile esotropia (5-180 months of age), 83 with accommodative...

www.PRSGlobalOpen.com Shimpei Miyamoto, MD Division of Plastic and Reconstructive Surgery National Cancer Center Hospital Tokyo, Japan Sir: T anterolateral thigh flap usually contains 2 comitant veins. The strength of the venous return flow differs between the 2 veins.1 To ensure flap survival, anastomosis of both veins has been recommended by several authors because there is little or no commu...

OBJECTIVE The aim of this study was to investigate the fractional anisotropy (FA) and mean diffusivity (MD) using a diffusion tensor imaging technique and whole-brain voxel-based analysis in patients with comitant strabismus. PATIENTS AND METHODS A total of 19 (nine males and ten females) patients with comitant strabismus and 19 age-, sex-, and education-matched healthy controls (HCs) underwe...

OBJECTIVE The aim of this study was to use amplitude of low-frequency fluctuation (ALFF) to investigate local features of spontaneous brain activity in patients with congenital comitant strabismus and clarify their relationship with emotional and psychosocial problems. METHODS A total of 20 patients with congenital comitant strabismus (ten males and ten females), and 20 healthy controls (ten ...

PURPOSE Computerized static stabilometry is a clinical test in neurologic and muscular diseases to assess postural stability or body sway in a quantitative manner. The purpose of this study was to examine whether postural stability would change in the process of the prism adaptation test in patients with intermittent and constant exotropia. METHODS Postural stability was measured before the p...

To compare the difference in white matter volume (WMV) and gray matter volume (GMV) between the comitant strabismus (CS) patients and health controls by voxel-based morphometry (VBM) and the relationship with behavioral performance. A total of 20 patients with comitant strabismus (10 males and 10 females), and 20 healthy subjects (10 males and 10 females) with matched age, sex status underwent ...

OBJECTIVE To evaluate the success rate of surgical corrections of constant and intermittent exotropias. STUDY DESIGN A case series. PLACE AND DURATION OF STUDY Al-Ibrahim Eye Hospital, Karachi, from July 2011 to December 2012. METHODOLOGY Patients having primary exotropia (deviation 15 - 45 prism diopters [PD]) were included. Patients with either constant exotropia or basic intermittent e...

Abstract Background Different surgical methods have been suggested for the correction of intermittent exotropia. Unilateral lateral rectus recession has described as a alternative small and moderate-angle In general, previous studies did not focus on outcomes unilateral in young children with The purpose this study is to evaluate treatment exotropia (? 25 PD (prism diopters)) children.
