Summary

A single drop of 1% cyclopentolate effectively dilates pupils for pediatric eye exams. This method simplifies the process, offering a viable alternative to multiple drops for better patient comfort and clinician efficiency.

Area of Science:

  • Ophthalmology
  • Pediatric Eye Care

Background:

  • Pediatric eye exams commonly require cycloplegia and dilation.
  • Current practice often involves 2-3 different eye drop medications for instillation ease.

Purpose of the Study:

  • To evaluate the efficacy of a single drop of a cycloplegic agent for pupil dilation in children.
  • To determine if a simplified instillation method can achieve adequate results for pediatric eye examinations.

Main Methods:

  • Children aged 1-7 years received 1% cyclopentolate in one eye and combination drops in the other.
  • Pupil diameter was measured, and iris color was classified after instillation.
  • Statistical analysis compared pupil dilation between different medication groups and eyes.

Main Results:

  • Mean pupil sizes were comparable across all groups (6.19-6.56 mm).
  • No statistically significant difference in pupil diameter was found between the paired eyes.
  • Iris color influenced dilation, with lighter irises showing greater dilation.

Conclusions:

  • A single drop of 1% cyclopentolate effectively achieves cycloplegia and pupil dilation for pediatric eye exams.
  • This single-drop approach is easier to administer and should be considered for routine pediatric eye care.
