β-blockers in the treatment of periocular infantile capillary haemangioma.

Infantile capillary haemangioma (IH) is the most common congenital vascular tumor of childhood and infancy. Although the majority of these lesions regress spontaneously, many of children with IH particularly in the periocular or orbital region need treatment. Ocular indications for treatment include obstruction of the visual axis or high degrees of astigmatism causing amblyopia, exposure keratopathy secondary to proptosis or compressive optic neuropathy. Our purpose was to assess the effectiveness and tolerance of beta-blockers (BB), propranolol and metoprolol, in the treatment of these lesions. We performed a retrospective review of 21 infant patients with periocular or/and orbital IH. The mode of treatment for 13 patients was with the non-selective beta blocker propranolol (PR) and 8 patients were treated with the beta 1 selective blocker metoprolol (ME). We analysed the changes in IH lesion size, colour and thickness after the treatment with beta-blockers, the onset and the period of their action, recurrence of IH and adverse effects of the treatment. The effectiveness of metoprolol to propranolol was compared as well as their use in combination with systemic steroids. In the first month of the treatment with beta-blockers, significant regression of the IH was observed in all patients. During the following months of treatment the regression was not rapid and after 6 to 12 months the lesions remained stationary. The final result of the treatment of 15 patients (71.4%) was deemed excellent while the treatment of 5 patients (23.8%) was deemed good. A single patient (4.7%) had only fair response to the therapy. During the whole series no serious life-threatening adverse effects were observed. The usage of beta-blockers, both propranolol and metoprolol, in the therapy of orbital and periocular capillary infantile haemangioma seems to be very effective in reduction of the tumor and had only rare, minimum adverse effects. These facts favour beta-blockers as the first line treatment of children with IH.
