[Cyclopentolate as a cycloplegic drug in determination of refractive error].
Cycloplegia is loss of the power of accommodation with inhibition of a ciliary muscle. We obtain in this way the smallest refraction of the lens and make it possible to determine the presence and size of the particular refractive error in cycloplegia by using cyclopentolate. Cyclopentolate is a synthetic anticholinergic drug and antagonist of the muscarine receptors. If applied in the eye, it b...
متن کاملA comparison of cycloplegic refraction to the near retinoscopy technique for refractive error determination.
The near retinoscopy technique of refractive error determination was compared to the standard method of cycloplegic refraction using 10 "infants" (3-12 months of age) and 10 "children" (32-109 months of age). There was a significant difference between the techniques for both sphere and cylinder power. Although there was no interaction of refractive technique and age group, the difference betwee...
متن کاملCorrelations between familial refractive error and children's non-cycloplegic refractions
We examined the spherical equivalent refractions of 237 subjects who had been seen four or more times in a longitudinal study of refractive development in normal children. We employed both photorefraction and autorefraction using a Canon R1 autorefractor. We performed an analysis of variance (F-test for Lack of Fit) to determine the significance of a linear regression in fitting these refractio...
متن کاملStatus of cyclopentolate as a cycloplegic in children: a comparison with atropine and homatropine.
We compared the cycloplegic effects of cyclopentolate, homatropine and atropine by the retinoscopy findings and residual accommodation left following their use in the same individual. The mean residual accommodation measured after the use of cyclopentolate, homatropine and atropine was 1.48 +/- 0.33 D, 2.32 +/- 0.37 D and 1.10 D +/- 0.28 D, respectively, and the mean difference in retinoscopy r...
متن کاملCycloplegic Refraction in Children with Cyclopentolate versus Atropine
The refracting power of the eye results from the static power of the eye (the combined ability of the cornea and the lens to bend incoming rays of light) and the accommodative power of the eye (the variable force of accommodation that alters the path of light rays by causing the ciliary body to change the curvature of the lens). The total increase in plus power that accommodation produces is kn...
