Insights
Topical glaucoma eye drops can cause severe systemic effects in infants, including central nervous system depression and cardiogenic shock. Careful evaluation of all topical medications is crucial for critically ill infants.
Area of Science:
- Pediatric Intensive Care
- Ophthalmology
- Clinical Toxicology
Background:
- Topical ocular medications are common for pediatric ophthalmic disorders.
- Congenital glaucoma requires prompt treatment, often with topical antiglaucoma agents.
Observation:
- Two infants in the pediatric intensive care unit presented with altered consciousness, hypotonia, hypothermia, bradycardia, and apnea after receiving topical antiglaucoma eye drops.
- One infant also experienced hypotension and broncho-obstruction.
Findings:
- Diagnosis of intoxication with topical antiglaucoma medications (brimonidine, brinzolamide, timolol) was established after excluding other causes.
- Both infants recovered fully after discontinuing eye drops and receiving symptomatic treatment.
Implications:
- Topically applied ophthalmic drops can lead to life-threatening systemic adverse effects in infants.
- Clinicians must consider topical medications as potential causes of critical illness in infants.
Abstract:
Topical ocular medications have been widely prescribed and successfully used in children for the management of different ophthalmic disorders. We present 2 infants admitted to our pediatric intensive care unit who developed altered state of consciousness, hypotonia, hypothermia, bradycardia, and apnea after instillation of ophthalmic drops. The second infant also had hypotension and broncho-obstruction. Few days before admission, both infants were diagnosed with congenital glaucoma, and topical antiglaucoma treatment was initiated. Ophthalmic drops with brimonidine and brinzolamide were prescribed to both patients, whereas the second infant also received topical timolol. After elimination of other possible causes, the diagnosis of intoxication with topical antiglaucoma medications was established. After discontinuation of eye drops and vigorous symptomatic treatment, both infants recovered without sequels. Topically applied ophthalmic drops may cause life-threatening systemic adverse effects in infants, such as central nervous system depression and cardiogenic shock. Moreover, these 2 patients illustrate the importance of careful evaluation of all topical medications and their consideration as possible causes of the derangements in critically ill infants.
