The Use of β-Blockers for the Treatment of Periocular Hemangiomas in Infants: A Report by the American Academy of Ophthalmology

PURPOSE

To review the published literature assessing the efficacy of β-blockers for the treatment of periocular hemangioma in infants.

METHODS

Literature searches were conducted in May 2018 in PubMed with no date restrictions and limited to studies published in English and in the Cochrane Library database without any restrictions. The combined searches yielded 437 citations. Of these,16 articles were deemed appropriate for inclusion in this assessment and assigned a level of evidence rating by the panel methodologist.

RESULTS

None of the 16 studies included in this assessment were rated level I, 3 were rated level II, and 13 were rated level III. The most common treatment regimen was 2 mg/kg daily oral propranolol, but intralesional and topical β-blockers were also used. Treatment effect was most often measured in terms of reduction in the size of the lesions, which occurred in the majority of patients. β-Blockers were consistently shown to reduce astigmatism, but this reduction was shown to be statistically significant in only 2 series. The effect of β-blockers on amblyopia was not adequately documented. β-Blockers were generally well tolerated and had mild side effects (fatigue, gastrointestinal upset/diarrhea, restlessness/sleep disturbances, minor wheezing, and cold extremities). Complications severe enough to require cessation of treatment occurred in only 2 patients out of a total of 229 who received β-blockers.

CONCLUSIONS

There is limited evidence to support the safety and efficacy of both topical and systemic β-blockers to promote regression of periocular hemangiomas. Additional research may confirm the best dosage and route of administration to maximize efficacy in reducing induced astigmatism and amblyopia associated with periocular hemangiomas while minimizing side effects.

Infantile hemangiomas treated by sequential application of pulsed dye laser and Nd:YAG laser radiation: a retrospective study

BACKGROUND AND OBJECTIVES

Infantile hemangiomas are the most common benign tumor in children. They have 3 phases of development: a proliferative phase, an involuting phase, and involution. Although active treatment is often not required, it is necessary in some cases. Of the possible treatments for hemangiomas, lasers have been shown to be effective in all phases of development. We report our experience with dual-wavelength sequential pulses from a pulsed dye laser and an Nd:YAG laser.

MATERIAL AND METHODS

This was a retrospective, descriptive study of patients with infantile hemangioma in different phases of development treated with pulsed dye laser pulses followed by Nd:YAG laser pulses. Four dermatologists assessed the effectiveness of treatment on a scale of 10 to 0. Adverse effects and incidents related to treatment were recorded. The median and interquartile range were calculated as descriptive statistics. Pretreatment and posttreatment comparisons were performed using the Wilcoxon test.

RESULTS

Twenty-two patients with hemangiomas in different phases of development were included. A statistically significant improvement was obtained both for the entire group and for different subgroups. Posttreatment events were reported in 4 patients, and included edema and ulceration, skin atrophy, and hyperpigmentation.

CONCLUSIONS

We believe that treatment with dual-wavelength light from a pulsed dye laser and a Nd:YAG laser is a viable treatment option for infantile hemangiomas when first-line therapies are ineffective or contraindicated.
