This was the first population-based study on periocular infantile hemangiomas in the United States. Over the 40-year period analyzed, the incidence was 1 in 1,586 live births and was most prevalent in white females with unilateral upper eyelid involvement. One in 5 had a history of maternal infertility, and 1 in 8 were born prematurely. Nine (21%) had an additional hemangioma outside the periocular region. Archives of Ophthalmology, July 2012
