Efficacy of a Cycloplegic Agent Administered as a Spray in the Pediatric Population

Purpose: To evaluate the efficacy and tolerability of cyclopentolate 1% administered as a spray in pediatric patients between 3 and 6 years old. Methods: In this prospective, randomized, parallel group study, healthy volunteers were randomly assigned to receive cyclopentolate 1% as a single drop or a single puff into closed eyes. Results: There were 61 patients included in the study; 31 received cyclopentolate 1% as drops and 30 received cyclopentolate 1% as spray. The mean age at presentation was 4.5 ± 1.07 years (range: 3 to 6 years) and 4.2 ± 1.06 years (range: 3 to 6 years) in the drops and spray groups, respectively. The distress level was significantly lower at the time of receiving cyclopentolate as a spray (P < .0001), with the exception of patients aged 6 years. There were no significant differences in pupil diameter between the two groups (P = .51), whereas 5 of 30 patients (16.6%) with dark irises who received cyclopentolate spray did not have adequate cycloplegia to allow for accurate refraction. Conclusions: Cycloplegia achieved with cyclopentolate 1% administered as a spray may be an option in uncooperative children because it is less distressing compared to cyclopentolate 1% drops. However, physicians should be aware that cycloplegia obtained is only partially effective in children with dark irises.
