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

, 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

Approach to cycloplegic refraction

Canadian Journal of Optometry
Children and younger adults are able to overcome some of the challenges posed by uncorrected refractive errors due to their potent accommodative abilities. However, this potent accommodative ability can significantly affect the precision of their refractive error’s assessment. To overcome this, paediatric cycloplegic refraction becomes indispensable as

Cycloplegic Versus Manifest Refractions

Canadian 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 ...

The Effect of Cycloplegia on Ocular Alignment and AC/A Ratio

Journal of Ophthalmic & Vision Research
Purpose: The present study sets out to investigate the effect of cyclopentolate-induced cycloplegia on distance and near deviation and the accommodative convergence/accommodation (AC/A) ratio. Methods: This prospective study was performed on 30 subjects.
