Vision screening in children:a retrospective study of social and demographic factors with regard to visual outcomes [PDF]

, 2015
BACKGROUND: Amblyopia and its risk factors have been demonstrated to be more common among children from low socioeconomic backgrounds. We sought to investigate this association in a region with orthoptic-delivered screening and whole population coverage,

Identification of ocular refraction based on deep learning algorithm as a novel retinoscopy method

BioMedical Engineering OnLine, 2022
Background The evaluation of refraction is indispensable in ophthalmic clinics, generally requiring a refractor or retinoscopy under cycloplegia. Retinal fundus photographs (RFPs) supply a wealth of information related to the human eye and might provide ...

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 ...

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 ...
