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 ...

Plusoptix photoscreener use for paediatric vision screening in Flanders and Iran [PDF]

open access: yes, 2019
Purpose Photoscreening assesses risk factors for amblyopia, as an alternative to measurement of visual acuity (VA) to detect amblyopia, on the premise that its early correction could prevent development of amblyopia.

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

Accommodative instability: relationship to progression of early onset myopia [PDF]

open access: yes, 2012
Background: In a previous study, we demonstrated that children with early onset myopia had greater instability of accommodation than a group of emmetropic children.
