Do all children need a cycloplegic refraction? A comparison of Mohindra's versus cycloplegic refraction [PDF]

open access: yesIndian Journal of Ophthalmology, 2020
Purpose: In 1–12 years old children, we assessed correlation, regression, and agreement between spherical equivalents (SE) obtained on Mohindra's near retinoscopy (MNR) and the post cycloplegic refraction (PCRef), performed 72 h after a cycloplegic ...

Prediction of cycloplegic refraction for noninvasive screening of children for refractive error. [PDF]

open access: yesPLoS ONE, 2021
Detection of refractive error in children is crucial to avoid amblyopia and its impact on quality of life. We here performed a retrospective study in order to develop prediction models for spherical and cylinder refraction in children.

A randomized clinical trial using cyclopentolate and tropicamide to compare cycloplegic refraction in Chinese young adults with dark irises [PDF]

open access: yesBMC Ophthalmology, 2021
Background To evaluate the necessity of cycloplegia for epidemiological studies of refraction in Chinese young adults (aged 17–22 years) with dark irises, and to compare the cycloplegic effects of 1% cyclopentolate and 0.5% tropicamide in them. Methods A

Agreement in non-cycloplegic and cycloplegic refraction between a photoscreener and a calibrated autorefractor [PDF]

open access: yesBMC Ophthalmology
Introduction Photoscreeners have been shown to provide excellent measurements of the refractive error. However, whether they could be used for assessing cycloplegic refraction has not been examied.

Comparison of objective refraction in darkness to cycloplegic refraction: a pilot study [PDF]

open access: yesAustralasian journal of optometry, The, 2016
The aim was to assess non-cycloplegic objective refraction in darkness using an open-field auto-refractor, and furthermore to compare it with distance cycloplegic subjective refraction and distance cycloplegic retinoscopy in the light, in children and young adults.Twenty-three, visually-normal, young-adults (46 eyes) ages 23 to 31 years, and five ...

Cycloplegic refraction is the gold standard for epidemiological studies [PDF]

open access: yesActa Ophthalmologica, 2015
AbstractMany studies on children have shown that lack of cycloplegia is associated with slight overestimation of myopia and marked errors in estimates of the prevalence of emmetropia and hyperopia. Non‐cycloplegic refraction is particularly problematic for studies of associations with risk factors.

Analysis of 2-year spherical equivalent progression in emmetropic children with non-cycloplegic refraction: a retrospective chart review [PDF]

open access: yesBMC Ophthalmology, 2023
Background We aimed to investigate children with an emmetropic non-cycloplegic refraction (NCR) to compare the difference in progression of NC spherical equivalent (SE) over 2 years between the children with emmetropic and hyperopic cycloplegic ...
