Clinical Performance of the Spot Vision Photo Screener before and after Induction of Cycloplegia in Children

open access: yesJournal of Ophthalmology, 2019
Aim. To compare the clinical performance of the Spot Vision Screener used to detect amblyopia risk factors (ARFs) in children before and after induction of cycloplegia; the children were referred because they met the screening criteria of the American ...

The influence of cycloplegic in objective refraction [PDF]

open access: yes, 2005
The purpose of this study was to compare refractions measured with an autorefractor and retinoscopy in cycloplegic and non-cycloplegic eyes. The objective refractions were performed in 199 right eyes from 199 healthy young adults with a mean age of 21.6

Changes in the anterior segment after cycloplegia with a biometer using swept-source optical coherence tomography.

open access: yesPLoS ONE, 2017
The aim of this study was to investigate changes in the anterior segment of the eye after cycloplegia. A biometer combined with swept-source optical coherence tomography (SSOCT) was used for measurements.

Study on accommodation by autorefraction and dynamic refraction in children

open access: yesJournal of Optometry, 2014
Purpose: Childhood accommodation interferes with accurate diagnosis of the latent refractive errors. Dynamic retinoscopy offers accurate measurements of accommodative response, while an autorefractometer can predict the accommodative system activation in

Light distortion and spherical aberration for the accommodating and nonaccommodating eye [PDF]

open access: yes, 2016
To evaluate how different amounts of induced spherical aberration (SA) affect the light distortion (LD) phenomena, tests were performed using an experimental device to measure the distortion (haloes, glare, and so on) of a point source. To simulate the

Hypo-accommodation responses in hypermetropic infants and children [PDF]

open access: yes, 2010
Aims: Accommodation to overcome hypermetropia is implicated in emmetropisation. This study recorded accommodation responses in a wide range of emmetropising infants and older children with clinically significant hypermetropia to assess common ...

Use of atropine to predict the accommodative component in esotropia with hypermetropia

open access: yesIndian Journal of Ophthalmology, 2011
This cohort study included children with esotropia and hypermetropia of ≥ +2.0 diopters (D). The deviation was measured at presentation, under atropine cycloplegia and 3 months after full refractive correction. Of 44 children with a mean age of 5.2 ± 2.4
