Independent and reciprocal accommodation in anisometropic amblyopia [PDF]

open access: yes, 2010
Accommodation is considered to be a symmetrical response and to be driven by the least ametropic and nonamblyopic eye in anisometropia. We report the case of a 4-year-old child with anisometropic amblyopia who accommodates asymmetrically, reliably ...

Uncorrected low hyperopia in young subjects induces postural instability even in those with clear visual acuity.

open access: yesPLoS ONE, 2019
Reports have indicated the effect of myopic blur on postural stability. The objective of this study was to investigate the minimum refractive error to significantly affect postural stability through a various levels of hyperopia and myopia induced by ...

The effect of unilateral disruption of the centrifugal visual system on normal eye development in chicks raised under constant light conditions [PDF]

open access: yes, 2016
The centrifugal visual system (CVS) comprises a visually driven isthmic feedback projection to the retina. While its function has remained elusive, we have previously shown that, under otherwise normal conditions, unilateral disconnection of centrifugal ...

Longitudinal Development of Refractive Error in Children With Accommodative Esotropia: Onset, Amblyopia, and Anisometropia. [PDF]

open access: yes, 2016
Purpose: We investigated longitudinal changes of refractive error in children with accommodative esotropia (ET) throughout the first 12 years of life, its dependence on age at onset of ET, and whether amblyopia or anisometropia are associated with ...
