PURPOSE To investigate the nature of early ocular misalignments in human infants to determine whether they can provide insight into the etiology of esotropia and, in particular, to examine the correlates of misalignments. METHODS A remote haploscopic photorefraction system was used to measure accommodation and vergence in 146 infants between 0 and 12 months of age. Infants underwent photorefr...

INTRODUCTION Suppression is a major sensorial abnormality in humans and monkeys with infantile strabismus. We previously reported evidence of metabolic suppression in the visual cortex of strabismic macaques, using the mitochondrial enzyme cytochrome oxidase as an anatomic label. The purpose of this study was to further elucidate alterations in cortical metabolic activity, with or without ambly...

BACKGROUND/AIM Many children with accommodative esotropia must continue spectacle use throughout life. This study was undertaken to determine which factors are predictive of successfully weaning children with accommodative esotropia out of spectacles. METHODS A retrospective review of 10 children with accommodative esotropia, who were gradually weaned from their hyperopic correction, and thre...

Sixteen patients with moderate angle esotropia of 30 to 35 prism dioptres were treated with a unilateral medial rectus muscle recession of 6 or 6.5 mm. Thirteen of sixteen patients (80%) were straight postoperatively or had 12 prism dioptres or less of esotropia. Three of the 16 had greater than 12 prism dioptres of esotropia, and none were exotropic. This procedure should be considered as an a...

Esotropia Figure 1 shows that the patient has esotropia of the left eye or what is commonly known as a squint or strabismus. The squint is an inward squint (synonyms include convergent squint or esodeviation of the eye). Esotropia is a condition where either one or both eyes are turned inward. Congenital esotropia, often seen in infants below six years old, may give rise to amblyopia. Accommoda...

purpose: to determine the surgical results of partially accommodative esotropia (paet). methods: thirty-eight patients with paet scheduled for surgery from 2002 to 2008 were enrolled in a descriptive, analytic retrospective study. patient characteristics including age, gender, refractive error, visual acuity, pre and post operative deviation, technique of surgery and follow up duration were rec...

A histochemical study was made of 13 cases of lipidoses of the central nervous system. Niemann-Pick's disease can be differentiated from other cerebral lipidoses by the finding that all affected cells store histochemically stainable phospholipids. Evidence has been adduced indicating that the material stored in infantile amaurotic idiocy is a complex containing ganglioside, cholesterol, and pos...
