Note: The 2018-19 edition of the BCSC Peds book indicates that the terms strawberry hemangioma and capillary hemangioma are outdated, and such lesions should be referred to simply as ‘hemangiomas.’ However, it also acknowledges that these terms persist in the ophthalmic literature. Because our community continues to use them, they will be included in this slide-set.

Because our community continues to use them, they will be included in this slide-set.Note also that the so-called cavernous hemangioma is considered(and therefore included with) the ‘malformations.’

Finally: Note that, per both the Peds and Orbit books, the term lymphangioma has been replaced with orbital lymphatic malformation.

Q
Among the orbital vascular lesions, where does the capillary hemangioma rank in terms of prevalence?It is the most common
Is there a gender predilection?Yes, it is more common in girls
At what age do orbital capillary hemangiomas present?About 1/3 are present at birth; almost all have ‘declared’ by age 6 months
What is the origin of these lesions?It’s not known for certain, but some experts believe they originate as nests of placental cells that ‘metastasized’ to the fetus
What is the ‘life cycle’ of capillary hemangiomas?--Initially they grow, reaching maximum size by around age 12 months--Then they involute beginning at about age 2 years--75% will resolve by age 4-5 years

Among the orbital vascular lesions, where does the capillary hemangioma rank in terms of prevalence?It is the most common
Is there a gender predilection?Yes, it is more common in girls
At what age do orbital capillary hemangiomas present?About 1/3 are present at birth; almost all have ‘declared’ by age 6 months
What is the origin of these lesions?It’s not known for certain, but some experts believe they originate as nests of placental cells that ‘metastasized’ to the fetus
What is the ‘life cycle’ of capillary hemangiomas?--Initially they grow, reaching maximum size by around age 12 months--Then they involute beginning at about age 2 years--75% will resolve by age 4-5 years

Disclaimer: These treatment guidelines were taken from the latest (2018-19) version of the BCSC Peds book. It should be noted that the Orbit book indicates that steroids(systemic or local) are the preferred first-line treatment for capillary hemangiomas. In contrast, the Peds book doesn’t even mention them. Which book is right? I’m going with the Peds version. As always, caveat emptor.
