Comparison Between cyclopentolate and (cyclopentolate 1% +tropicamide 1%) on the cycloplegic efficiency in children
Abstract
Purpose:
compares the effect of cyclopentolate 1% versus combination ( cyclopentolate 1% +tropicamide 1% ) on the ( cycloplegic onset , cycloplegic efficiency and pupil diameter) .
Patients and methods:
This was an analytical cross-sectional study involving children aged 5 to 18 years with dark irides who were attending ophthalmology clinic in Tishreen University Hospital in lattakia. Cyclopentolate 1% was installed in left eye three time at 5 minute intervals, and cyclopentolate 1% was installed in right eye three time at 5 minute intervals with two drops of Tropicamide 1% (one drop after 1 minute of cyclopentolate first drop and one drop after 1 minute of cyclopentolate second drop). Refractive errors, spherical equivalent and pupillary diameter were recorded before the first drop and after drop during 5, 10, 15, 20, 30, 60 minutes.
Results:
Cyclopentolate 1%-Tropicamide 1% combination had rapid onset of cycloplegia (5 versus 10 minutes) and shorter time of maximal cycloplegia (30 versus 60 minutes)
Conclusion:
Cyclopentolate 1% - Tropicamide 1% combination was superior to Cyclopentolate 1% in rapidity of cycloplegic onset and time of maximal cycloplegia.
