Patient-reported Outcomes for Assessment of Quality of Life in Refractive Error: A Systematic Review.

Optometry and Vision Science, 2017
SIGNIFICANCE This review has identified the best existing patient-reported outcome (PRO) instruments in refractive error. The article highlights the limitations of the existing instruments and discusses the way forward.

Refractive Errors in Children

Pediatric Clinics of North America, 1987
Optical correction of refractive errors in infants and young children is indicated when the refractive errors are sufficiently large to cause unilateral or bilateral amblyopia, if they are impairing the child's ability to function normally, or if the child has accommodative strabismus.

Refractive Errors in Twin Studies

Twin Research and Human Genetics, 2006
AbstractIt is estimated that 1.6 billion people worldwide have myopia, a refractive error, and this number is expected to increase to approximately 2.5 billion by the year 2020. It is now well established that both the environment and genetics play a role in the development of myopia.

REFRACTIVE ERRORS

1987
Publisher Summary A common cause of blurred vision is refractive error. This is a physiological condition where the refracting system of the eye fails to focus objects sharply on the retina. It is usually corrected with glasses. Myopia is an optical condition where distant objects are focused in front of the retina so that vision for distance is ...

Refractive errors and refractive development in premature infants

Journal Français d'Ophtalmologie, 2015
To examine refractive errors and refractive development in premature infants.Premature infants in the retinopathy of prematurity (ROP) screening program were recruited and examined longitudinally between 28 and 58 weeks postmenstrual age. For performing cycloplegic retinoscopy, 1% tropicamide was administered, two drops with a 10-minute interval, in ...

Uncorrected Myopic Refractive Error Increases Microsaccade Amplitude.

Investigative Ophthalmology and Visual Science, 2015
PURPOSE Human brain generates miniature eye movements, such as microsaccades, to counteract image fading due to visual adaptation. Generation of microsaccade relies on the amount of retinal error or acuity demand for a desired visual task.

MECHANISMS OF ACCOMMODATION AND REFRACTIVE ERROR*

Ophthalmic and Physiological Optics, 1983
Abstract The classical or Helmholtz theory of accommodation has formed the basis of optometric practice for many years. This theory maintains that the ciliary muscle receives only parasympathetic innervation and that the position of rest in the emmetropic eye lies at optical infinity.

Refractive Error in the Geriatric Population

2009
An 88-year-old African-American male is sent by his primary care physician for retinal evaluation for diabetic retinopathy. He has had worsening diabetes control requiring insulin therapy. He moved to the area after the death of his wife, who had been his primary caregiver, and is currently living with his daughter.
