Peripheral refraction and higher-order aberrations with cycloplegia and fogging lenses using the BHVI-EyeMapper

open access: yesJournal of Optometry, 2016
Purpose: To determine if a fogging lens ameliorates accommodative effects driven by the closed-view design of the BHVI-EyeMapper (EM) instrument. We compared cycloplegic refraction and higher-order aberration measurements of the EM with those obtained ...

Comparison of ocular accommodation throughout the day in children using 0.05% low‐dose atropine versus controls: A pilot study

open access: yesOptometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Purpose The purpose of this pilot study was to assess the effect of 0.05% low‐dose atropine on ocular accommodation (amplitude and accuracy) and how its effect changed throughout the day. Methods Sixteen children aged 6–16 years using 0.05% atropine and 16 controls not using atropine were enrolled.

Relationship between higher-order wavefront aberrations and natural progression of myopia in schoolchildren

open access: yesScientific Reports, 2017
This study investigated the relationship between higher-order aberrations (HOAs) and myopia progression as well as axial elongation in schoolchildren. We examined cycloplegic refraction, axial length, and wavefront aberrations prospectively in 71 myopic ...

Self-refraction, ready-made glasses and quality of life among rural myopic Chinese children: a non-inferiority randomized trial. [PDF]

open access: yes, 2016
PURPOSE: To study, for the first time, the effect of wearing ready-made glasses and glasses with power determined by self-refraction on children's quality of life. METHODS: This is a randomized, double-masked non-inferiority trial.

Test–retest reliability of clinical accommodative measures in adolescents

open access: yesOptometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Purpose To determine long‐term (3 months) test–retest reliability of accommodative testing in adolescents with normal accommodative amplitude. Methods Participants aged 12 years to <17.5 years with normal accommodative amplitude (minimum of 11 diopters [D]) and binocular vision were enrolled.

Visual performance and ocular abnormalities in deaf children and young adults: a literature review [PDF]

open access: yes, 2013
Visual defects are common in deaf individuals. Refractive error and ocular motor abnormalities are frequently reported, with hyperopia, myopia, astigmatism and anomalies of binocular vision, all showing a greater prevalence in deaf individuals compared ...

Impact of uncorrected hyperopia on visual function and academic performance in preschool and school‐age children

open access: yesOptometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Many children with a moderate amount of farsightedness do not see as well up close as children who are not farsighted, and they often have significantly more problems with near visual function (near visual acuity, stereoacuity, and accommodation), early literacy skills, reading, and attention.

Assumption-free estimation of the genetic contribution to refractive error across childhood [PDF]

open access: yes, 2015
Purpose: Studies in relatives have generally yielded high heritability estimates for refractive error: twins 75–90%, families 15–70%. However, because related individuals often share a common environment, these estimates are inflated (via misallocation ...
