Cycloplegic Refraction in Children with Cyclopentolate versus Atropine
نویسنده
چکیده
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 known as, the amplitude of accommodation [1].

A cross-over study of the cycloplegic effects of a single topical application of cyclopentolate-phenylephrine and routine atropinization for 3.5 days.
Static refraction in children after the topical instillation of atropine twice a day during 3.5 days was compared with the refraction after a single instillation of one drop of 0.85% cyclopentolate + 1.5% phenylephrine in a randomized cross-over study. Atropine eye drops were applied by the parents at home, while the combination drop was applied by personnel at the eye clinic. Refraction was de...

PURPOSE To compare the cost and effectiveness of three cycloplegic agents among Nigerian children. METHODS Two hundred thirty-three children aged 4 to 15 years attending outpatient eye clinics in Nigeria were randomized to (1) 1% cyclopentolate, (2) 1% cyclopentolate and 0.5% tropicamide, or (3) 1% atropine drops in each eye (instilled at home over 3 days). Ten children were lost to follow-up...

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...

PURPOSE To evaluate the effectiveness of a cycloplegic regimen using 0.5% tropicamide and 0.5% phenylephrine (Tropherine, Hanmi Pharm), in addition to 1% cyclopentolate, in hyperopic children. METHODS The medical records of hyperopic patients below the age of 14 years who had undergone cycloplegic retinoscopy were retrospectively reviewed. Cycloplegic refractions were performed using one of t...

Accurate measurement of refractive error in uncooperative patients and young children, requires cycloplegia. The aim of the present study was to determine whethere cyclopentolate by itself or in combination with 4 times instillation of atropine can be used as a substitute for 10 times instillation of atropine. From 1994 to 1996, 39 patients aged 2-12 years were included in this study. Cyclopleg...
