Insights
Topical eye drops can cause systemic adverse effects in infants. Physostigmine successfully treated respiratory distress, a rare side effect of cyclopentolate, in an infant.
Area of Science:
- Ophthalmology
- Pediatrics
- Clinical Toxicology
Background:
- Topical ophthalmic medications can lead to systemic adverse effects, particularly in pediatric patients.
- Infants possess unique physiological characteristics increasing their susceptibility to systemic toxicity from eye drops.
Observation:
- Cyclopentolate, a common cycloplegic agent, can rarely cause respiratory distress in infants.
- Prompt identification of systemic toxicity signs is crucial for effective management.
Findings:
- This case report details an infant experiencing respiratory distress following topical cyclopentolate administration.
- Successful management of cyclopentolate-induced respiratory distress was achieved with physostigmine treatment.
Implications:
- Physostigmine should be considered a potential antidote for severe, life-threatening systemic adverse effects of cyclopentolate in infants.
- Close monitoring and timely intervention are vital when administering topical cyclopentolate to pediatric populations.
Abstract:
Topical application of eye drops may cause mild or severe adverse ocular or systemic effects. Children, particularly infants, are more prone to systemic adverse effects of topical eye drops because of their lower body mass and blood volume, immature metabolism, and immaturity of excretory, nervous, and cardiovascular systems. Early recognition of signs and symptoms of systemic toxicity is very important. Most of the signs and symptoms can resolve spontaneously; however, in severe cases, physostigmine treatment may be required. Respiratory distress is a rare adverse effect of cyclopentolate. We report an infant who developed respiratory distress after ocular instillation of cyclopentolate and was successfully treated with physostigmine. The benefit of physostigmine use with close follow-up should be borne in mind in cases with a life-threatening cyclopentolate adverse effect.
