PURPOSE To examine the effects of strabismic amblyopia and strabismus only, without amblyopia, on the temporal patterns of eye-hand coordination during both the planning and execution stages of visually-guided reaching. METHODS Forty-six adults (16 with strabismic amblyopia, 14 with strabismus only, and 16 visually normal) executed reach-to-touch movements toward targets presented randomly 5°...

purpose: to determine the prevalence of amblyopia and its determinants in students of region 1 in mashhad, 2006. methods: using randomized cluster sampling, 2510 students were selected to undergo ophthalmologic examinations. amblyopia was defined as corrected visual acuity of 8/10 or less in either eye. results: of the 2510 selected student, 2150 were examined (85.6% participation rate). the pr...

Amblyopia, also known as lazy eye, usually occurs during early childhood and results in poor or blurred vision. Recent neuroimaging studies have found cortical structural/functional abnormalities in amblyopia. However, until now, it was still not known whether the spontaneous activity of the brain changes in amblyopia subjects. In the present study, regional homogeneity (ReHo), a measure of the...

Purpose Amblyopia is associated with a broad array of perceptual and neural abnormalities in the visual system, particularly in untreated or unsuccessfully treated populations. Traditionally, it has been believed that the neural abnormalities are confined to the visual cortex and subcortex (e.g., lateral geniculate nucleus). Here, we investigate the presence of neuroanatomical abnormalities ear...

The management of strabismus in Cameroon is not well developed and the average age of first consultation is beyond the age amblyopia reversal. It is with the aim of improving strabismus management that we undertook this prospective and descriptive study which spanned 11 months. The objective was to describe amblyopia in patients with comitant strabismus at their first visit. Data collected incl...

Amblyopia is a visual impairment secondary to abnormal visual experience (e.g., strabismus, anisometropia, form deprivation) during early childhood that cannot be corrected immediately by glasses alone. It is the most common cause of monocular blindness globally. Patching remains the mainstay of treatment, but it is not always successful and there are also compliance and recurrence issues. Beca...

PURPOSE The purpose of this study was to document the prevalence of anisometropia, anisoastigmatism, and anisometropic amblyopia in patients with neurofibromatosis-1 (NF1) and to compare it with that in age- and sex-matched controls. METHODS Fifty patients with NF1 and 150 age- and sex-matched controls were examined in this study. Cycloplegic autorefraction was attempted on all patients <16 y...

STUDY OBJECTIVE To investigate the relationship between age at presentation of amblyopia and social deprivation before and after the introduction of changes to a vision screening service. DESIGN Two cohorts of children treated for amblyopia in 1983 and 1992. SETTING THe orthoptic department of Leicester Royal Infirmary. PARTICIPANTS The 209 patients treated for amblyopia who first attende...
