  1. PURPOSE: Given the prominence of central vision in humans, it has been assumed that visual signals from the fovea dominate emmetropization. The purpose of this study was to examine the impact of peripheral vision on emmetropization. METHODS:…
  2. INTRODUCTION: This study aims to understand off-axis refraction during accommodation and to identify whether the relative hyperopia generally observed in myopic eyes changes with accommodation. METHOD: Twenty bilateral myopes (18 to 33 years)…
  3. PURPOSE: To evaluate refractive error, axial length, and relative peripheral refractive error before, during the year of, and after the onset of myopia in children who became myopic compared with emmetropes. METHODS: Subjects were 605 children 6 to…
  4. Peripheral refractive error degrades the quality of retinal images and has been hypothesized to be a stimulus for the development of refractive error. The purpose of this study was to investigate the changes in refractive error across the horizontal…
  5. It has been suggested that emmetropic and low-hyperopic eyes in which the refractive error in the periphery of the visual field is relatively hyperopic with respect to the axial refraction may be at greater risk of developing myopia than eyes with…
  6. PURPOSE: The present study investigated the relationship between parental refractive error and myopia progression in their offspring and the interaction between parental ametropia and the effects of wearing progressive-addition (PALs) or…
  7. PURPOSE: The purpose of this study is to investigate the comparative clinical performance of two hyper Dk contact lenses: a silicone hydrogel lens (Focus Night & Day, Ciba Vision) and a rigid lens (Z-alpha, Menicon Co. Ltd.) when worn for up to 30…
  8. PURPOSE: To identify whether parental history of myopia and/or parent-reported children's visual activity levels can predict juvenile-onset myopia. METHODS: Survey-based data from Orinda Longitudinal Study of Myopia subjects from 1989 to 2001 were…
  9. Myopia is a significant public health problem and its prevalence may be increasing over time. The main treatment options of single vision spectacle lenses, contact lenses, and refractive surgery do not slow the accompanying eye growth or retard the…
  10. PURPOSE: The purpose of this study is to measure refraction across the horizontal central visual field in orthokeratology patients before and during treatment. METHODS: Refractions were measured out to 34 degrees eccentricity in both temporal and…
  11. PURPOSE: Because of the prominence of central vision in primates, it has generally been assumed that signals from the fovea dominate refractive development. To test this assumption, the authors determined whether an intact fovea was essential for…
  12. PURPOSE: The Mars Letter Contrast Sensitivity Test (initially known as the Lighthouse Letter Contrast Sensitivity Test) is similar in design to the Pelli-Robson Test but may offer several advantages. This study evaluates the repeatability of the…
