Cycloplegic refraction and non-cycloplegic refraction using contralateral fogging: a comparative study

Journal of Modern Optics, 2007
The purpose of this study is to compare the retinoscopy values obtained from cycloplegic refraction and non-cycloplegic refraction done with contralateral fogging procedure on children. Performing retinoscopy on children is a challenge because of two significant problems encountered during the procedure, which include maintaining fixation and control ...

Cycloplegic refraction using atropine minidrops

Strabismus, 1993
Topical application of atropine for cycloplegic refraction may be associated with alarming systemic reactions in infants and children. Cycloplegic refraction and pulse rate were compared after short-term minidrop application of atropine with a calibrated pipette (3 × 5 μl) and standard atropine application from commercial bottles (twice daily 30-36 μ1 ...

A longitudinal study of cycloplegic refraction in a cohort of 350 Japanese schoolchildren. Cycloplegic refraction

Ophthalmic and Physiological Optics, 1999
SummaryWe performed a 5 year longitudinal study of cycloplegic refraction in a cohort of 350 Japanese schoolchildren from 6 to 11 years of age in a rural area of southwestern Japan. The spherical refraction was measured under cycloplegia with an infrared autorefractometer. The grouped data from 350 right eyes showed leptokurtic frequency distributions,

Cycloplegic Refraction After Echothiophate Iodide

Journal of Pediatric Ophthalmology & Strabismus, 1983
ABSTRACT Retinoscopy under cycloplegia using cycle pen to late (Cyclogyl) hydrochloride was performed on 18 patients (36 eyes) with partial or complete accommodative esodeviation, during and after treatment with echothiophate (Phospholine) iodide.

Relationship Between Cycloplegic and Wavefront-derived Refraction

Journal of Refractive Surgery, 2003
ABSTRACT PURPOSE: To compare cycloplegic refractions to preoperative wavefront-derived refractions from three Hartmann-Shack-based wavefront devices. METHODS: Ninety-nine eyes of 55 subjects were evaluated preoperatively using the LADARWave, WaveScan, and Zywave aberrometers.

Refraction Using Mydriatic, Cycloplegic, and Manifest Techniques

American Journal of Ophthalmology, 1973
In measuring refractive errors, the oph­ thalmologist especially uses cycloplegic drugs. Refractive defects are common in pa­ tients with eye complaints. Various types of eye defects are found in all age groups. Al­ most every patient seen by an ophthalmolo­ gist is refracted at some time during his care.

Cycloplegic Refractions in Infants and Young Children

American Journal of Ophthalmology, 1980
We studied groups of normal infants and infants with amblyopia and esoropia to determine the incidence of infantile astigmatism. Under cycloplegia, 19% of normal infants had astigmatism; this was at least twice the incidence in adults, but less than one-hale that found by noncycloplegic refractions of infants. During the first three postnatal years the

Comparing homatropine and atropine in pediatric cycloplegic refractions

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2011
To compare cycloplegic efficacy of homatropine and atropine in pediatric refractions and derive a regression formula to calculate refraction findings for both agents.Children between the ages of 4 to 10 years with refractive error underwent cycloplegic refraction with 2% homatropine and 1% atropine by retinoscopy and automated refraction.
