Comparative Study of Refraction between Wave Front-Based Refraction and Autorefraction without and with Cycloplegia in Children and Adolescents

Children, 2022
The main aim of this study was to compare refraction measurements with and without cycloplegia from two refractors devices, (TRK-2P autorefractometer (TRK-2P) and wavefront-based refraction Visionix 130 (VX130)) in children and adolescents.

Refractive errors in 3-6 year-old Chinese children: a very low prevalence of myopia?

, 2015
PURPOSE To examine the prevalence of refractive errors in children aged 3-6 years in China. METHODS Children were recruited for a trial of a home-based amblyopia screening kit in Guangzhou preschools, during which cycloplegic refractions were measured in

Comparison between cycloplegic and noncycloplegic refraction in young adult myopes

Optometry and Vision Science
SIGNIFICANCE This study explores the difference between cycloplegic and noncycloplegic refraction in young adult myopes. PURPOSE From the available literature, it is unclear whether cycloplegia is necessary when refracting young adults.

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

Acta Ophthalmologica, Volume 104, Issue 3, Page 267-279, May 2026.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated

Longitudinal Development of Refractive Error in Children With Accommodative Esotropia: Onset, Amblyopia, and Anisometropia. [PDF]

, 2016
Purpose: We investigated longitudinal changes of refractive error in children with accommodative esotropia (ET) throughout the first 12 years of life, its dependence on age at onset of ET, and whether amblyopia or anisometropia are associated with ...

A comparison of cycloplegic effect of cyclopentolate 0.5% versus 1.0% eye drops with five different refraction measurement modalities in young adults

Graefe's Archive for Clinical and Experimental Ophthalmology
To compare the refraction before and after cycloplegia with 0.5% and 1.0% cyclopentolate eye drops using five different measurement modalities. This prospective, clinical comparative study enrolled 96 eyes of 48 healthy patients with a mean age of 26.6 ±

The longitudinal associations of reading, writing and screen time with myopia at age 9 years among children from the GUSTO birth cohort

Acta Ophthalmologica, Volume 104, Issue 3, Page e337-e345, May 2026.
Abstract Purpose To investigate the associations between paper‐based reading and writing time, screen‐based time at ages 2, 3, 6 and 9 years and myopia at age 9 in the GUSTO birth cohort. Methods The GUSTO study recruited pregnant women from two Singapore public maternity hospitals between 2009 and 2010. Parent‐reported reading and writing time, screen

Receding and disparity cues aid relaxation of accommodation [PDF]

, 2009
Purpose. Accommodation can mask hyperopia and reduce the accuracy of non-cycloplegic refraction. It is, therefore, important to minimize accommodation to obtain a measure of hyperopia as accurate as possible.

Orthotropic Outcome With Spectacle Correction in a Pediatric Case of Refractive Esotropia and Anisometropic Amblyopia

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Early and accurate spectacle correction in children with refractive esotropia and anisometropic amblyopia can restore orthotropia, improve visual acuity, and prevent long‐term amblyopia. Timely diagnosis, careful refractive assessment, and individualized management are crucial.
