comparative study of cycloplegic drugs in clinical refraction
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...
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 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...
متن کاملThe influence of cycloplegia in objective refraction.
The purpose of this study was to compare refractions measured with an autorefractor and by retinoscopy with and without cycloplegia. The objective refractions were performed in 199 right eyes from 199 healthy young adults with a mean age of 21.6 +/- 2.66 years. The measurements were performed first without cycloplegia and repeated 30 min later with cycloplegia. Data were analysed using Fourier ...
متن کاملNon-cycloplegic spherical equivalent refraction in adults: comparison of the double-pass system, retinoscopy, subjective refraction and a table-mounted autorefractor.
AIM To evaluate the accuracy of spherical equivalent (SE) estimates of a double-pass system and to compare it with retinoscopy, subjective refraction and a table-mounted autorefractor. METHODS Non-cycloplegic refraction was performed on 125 eyes of 65 healthy adults (age 23.5±3.0 years) from October 2010 to January 2011 using retinoscopy, subjective refraction, autorefraction (Auto kerato-ref...
