Strabismic amblyopia.
NOTWITHSTANDING the vast literature, a complete and satisfactory definition of the clinical picture of amblyopia in strabismus has not yet been produced, and some symptoms are often confused with those of other forms of functional amblyopia. Bangerter (1953) and many other authors embrace in the term " amblyopia ex anopsia" the amblyopia observed in anisometropia, in high ametropia, and in nyst...
متن کاملImage segregation in strabismic amblyopia
Humans with naturally occurring amblyopia show deficits thought to involve mechanisms downstream of V1. These include excessive crowding, abnormal global image processing, spatial sampling and symmetry detection and undercounting. Several recent studies suggest that humans with naturally occurring amblyopia show deficits in global image segregation. The current experiments were designed to stud...
متن کاملStrabismic Amblyopia: When to Treat the Amblyopia, When to Operate
Introduction: Strabismic amblyopia is frequently encountered by pediatric ophthalmologists and orthoptists. An understanding of its onset and of the timing of treatment may lead to better long-term treatment results. Methods: A review was conducted of past and recent literature pertaining to strabismic amblyopia. Articles relevant to further understanding the onset, course, and management of st...
متن کاملElectrophysiological and psychophysical differences between early- and late-onset strabismic amblyopia.
PURPOSE To compare visual evoked potentials (VEPs) and contrast sensitivity in adults with early- or late-onset strabismic amblyopia. METHODS Twelve adults with early- and 12 with late-onset strabismic amblyopia with similar ranges of visual acuity were studied. Pattern-onset VEPs to 30-minute checks were recorded at a range of contrast levels. Contrast sensitivity (CS) was measured at 3.2 cy...
متن کاملIntegration of local orientation in strabismic amblyopia
In order to investigate the processes which integrate local orientation information in observers with strabismic amblyopia, we measured contrast thresholds for discriminating the global orientation of a pattern (3 "bars") comprised of Gabor patches. We found that in both eyes of amblyopic observers, as has been reported for normal observers [Saarinen, Levi & Shen (1997) Proceedings of the Natio...
