β-blockers in the treatment of periocular infantile hemangioma

Abstract

Purpose of review: To evaluate the medical literature on the use of β-blockers, through different routes, for the treatment of periorbital infantile hemangiomas and to summarize the recommendations available on dosage and monitoring.

Recent findings: β-blockers for the treatment of infantile hemangioma are now considered to be first-line treatment. Growing literature on the role of oral propranolol confirmed its efficacy but also presented its multiple side-effects including hypotension, bradycardia, hypoglycemia, and bronchospasm. No universal guidelines exist concerning pretreatment evaluation, dosage, monitoring, and duration of treatment but different protocols have been created.In the aim of minimizing side-effects, other routes of administration and more selective β-blockers have emerged. Many studies showed promising results for topical timolol especially in the treatment of superficial hemangiomas. Few studies evaluated intralesional propranolol. Limited data exist on the use of more selective β-blockers promising similar results to propranolol with fewer side-effects.

Summary: Oral β-blockers are now the mainstay of treatment for periorbital hemangiomas but still with no consensus on their administration and monitoring. The topical form or more selective β-blockers may be the solution to minimize side-effects.
