Purpose—To review what is known about the normal maturation of stereoacuity, the stereoacuity deficits associated with infantile and accommodative esotropia, the rationale for making improved stereoacuity a goal of treatment, and strategies for improving stereoacuity outcomes. Methods—Studies of stereoacuity maturation during normal development, studies of stereoacuity outcomes following treatm...

IMPORTANCE We devised the optokinetic uncover test to examine the role of peripheral retinal motion input in generating horizontal optokinetic responses in patients with infantile strabismus. OBJECTIVE To ascertain whether subcortical visual input contributes to the asymmetrical monocular optokinetic responses that characterize infantile esotropia. DESIGN AND SETTING Observational study in ...

AIM Recent studies suggest that Asian strabismus patterns are different from those in the West. This study aims to determine the profile of children with comitant horizontal strabismus in Singapore. METHOD 682 children aged <or=16 years presenting with strabismus for the first time between 2000 and 2002 were included in this study. The type and size of the squint, visual acuity, refractive er...

PURPOSE To determine the maturational course of nasotemporal asymmetry in infantile esotropia and to define the relationships among the symmetry of the motion visual evoked potential (MVEP), eye alignment, fusion, and stereopsis. METHODS Sixty healthy term infants and 34 infants with esotropia participated. Nasotemporal MVEP asymmetry was assessed by the presence of a significant F1 response ...

Objectives: Manifest strabismus in children is a major cause of suboptimum visual experience with attendant impact on their development. This study aims to determine the pattern manifest among attending Paediatric Ophthalmology clinic University Port Harcourt Teaching Hospital, Rivers State. Materials and method: One hundred twenty-five (125) children, aged 6 months 18 years were ...

INTRODUCTION Recent studies of human infants have described a spectrum of early-onset esotropia, from small angle to large heterotropias. We report here a similar spectrum of early-onset esotropia in infant monkeys, with emphasis on the relationship between visuomotor deficits, central nervous system circuitry, and orbital anatomy. METHODS Eye movements were recorded in macaque monkeys with n...
