Independent and reciprocal accommodation in anisometropic amblyopia [PDF]

, 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 ...

A retinoscopic survey of 333 horses and ponies in the UK [PDF]

, 2014
Introduction: Ophthalmic examination in the horse is generally limited to crude assessment of vision and screening for ocular lesions. The refractive state of equine eyes and the potential impact on vision and performance requires further ...

Effect of induced hyperopia on fall risk and Fourier transformation of postural sway [PDF]

PeerJ, 2019
Background and Purpose Fall accidents are a social challenge in Korea and elsewhere. Most previous studies have focused on the effects of reduced visual acuity due to myopia on falls and body balance.

Genome-wide search for strabismus susceptibility loci. [PDF]

, 2003
The purpose of this study was to search for chromosomal susceptibility loci for comitant strabismus. Genomic DNA was isolated from 10mL blood taken from each member of 30 nuclear families in which 2 or more siblings are affected by either esotropia or ...

Electroretinography and Gene Expression Measures Implicate Phototransduction and Metabolic Shifts in Chick Myopia and Hyperopia Models

Life, 2021
The Retinal Ion-Driven Fluid Efflux (RIDE) model theorizes that phototransduction-driven changes in trans-retinal ion and fluid transport underlie the development of myopia (short-sightedness).

Flash Electroretinography as a Measure of Retinal Function in Myopia and Hyperopia: A Systematic Review

Vision, 2023
Refractive errors (myopia and hyperopia) are the most common visual disorders and are severe risk factors for secondary ocular pathologies. The development of refractive errors has been shown to be associated with changes in ocular axial length ...
