Non-cycloplegic refraction cannot replace cycloplegic refraction when screening for refractive errors in children

open access: yes, 2022
The purpose was to assess the differences in spherical equivalent refractive error (SER) between cycloplegic autorefraction (1% cyclopentolate), non-cycloplegic autorefraction, and non-cycloplegic retinoscopy measured by experienced optometrists in a population with a high prevalence of hyperopia. Refractive error was measured with the three methods in

Cycloplegic Versus Manifest Refractions

open access: yesCanadian Journal of Optometry, 1982
With the precedent set by the New Brunswick Optometric Association and upcoming changes in drug legis­lation in several western provinces; optometrists across Canada are be­coming increasingly aware of the use of diagnostic pharmaceuticals. The following report compares the re­fractive status of 423 eyes when ex­amined by manifest and cycloplegic ...

Cycloplegic and Noncycloplegic Refractions of Chinese Neonatal Infants

open access: yesInvestigative Opthalmology & Visual Science, 2011
To examine Chinese neonatal infants with both cycloplegic and noncycloplegic retinoscopy and to compare the distribution of refractive errors for the two techniques.Cycloplegic retinoscopy was performed by two experienced pediatric ophthalmologists on 81 neonatal infants randomly selected from a group of 185 neonates who had undergone noncycloplegic ...
