ABSTRACT: To review and evaluate the medical literature on new treatments for periocular infantile (capillary) hemangioma. Recent studies have shown a promising new therapy for infantile hemangioma using nonselective β-blockers, including oral propranolol and topical timolol. Conventional treatments for infantile hemangioma include the use of corticosteroids, laser, surgery, and immunomodulator therapy. Recently, systemic and topical β-blockers have been used to successfully treat infantile hemangioma. The drugs' mechanism of action remains uncertain, but plausible theories include vasoconstriction, modulation of pro-survival signal transduction pathways, and endothelial cell apoptosis. Whereas no life-threatening adverse events from β-blocker treatment have been described, there have been reports of bradycardia, hypotension, bronchospasm, hypoglycemia, and electrolyte disturbances resulting from systemic use of propranolol to treat infantile hemangioma. Sleep and gastrointestinal disturbances have also been frequently reported. Topical timolol application for localized, superficial tumors may confer similar efficacy as oral propranolol while reducing systemic effects. Despite the recent explosion of interest surrounding this novel treatment, current treatment and protocol-monitoring recommendations are based largely on the experience of individual centers. Several randomized controlled studies are currently underway, the results of which will guide future standard-of-care treatment for infantile hemangioma.Current opinion in ophthalmology 09/2011; 22(5):419-25.

ABSTRACT: To evaluate the optical and anatomical effects of oral propranolol treatment for infantile periocular capillary haemangioma. All children diagnosed with infantile capillary haemangioma in 2008-2010 at a tertiary paediatric medical centre underwent comprehensive evaluation, including imaging, by a multidisciplinary team followed by oral propranolol treatment. Clinical follow-up was performed regularly until the lesions disappeared. Main outcome measures included changes in anatomical extraocular extension, refractive sphere and cylindrical power, and spherical equivalent in the involved eye before and after treatment and between the two eyes. A total of 30 patients (8 male; mean age at diagnosis, 1.6±2.8 months) participated. The lesions affected the left eye in 53.3% and were located preseptally in 83.3%. Four patients (13.3%) received steroids before propranolol. A treatment dosage of 2 mg/kg per day was started at mean age 5.0±4.5 months, 3.3±4.3 months from disease onset. Side effects occurred in 11 patients and warranted a dose reduction (to 1 mg/kg per day) in 3 and treatment termination in 1. Findings were significant for mean reduction in involved extraocular area (P<0.0001), post-treatment reduction in mean cylindrical power in involved eyes (P=0.02), pre- and post-treatment differences in mean cylindrical power between involved and uninvolved eyes (P=0.02 and P=0.01, respectively), and post-treatment change in absolute values of mean spherical power between involved and uninvolved eyes (P=0.025). Early diagnosis of infantile periocular capillary haemangioma and prompt treatment with propranolol lead to a significant reduction in the involved ocular area, in astigmatism, and prevent ocular/facial disfiguration/deformation, without rebound. Propranolol is recommended as the preferred treatment compared with other accepted therapies.Eye (London, England) 09/2011; 25(12):1627-34. DOI:10.1038/eye.2011.233 · 1.90 Impact Factor
