Capillary hemangioma
Oculoplasty
Key Points
- •Capillary hemangioma is the most common benign orbital tumor of infancy; increases in size with crying (key differentiator from dermoid cyst); positive for GLUT-1 (pathognomonic)
- •Triphasic course: rapid proliferation (0–12 months), then slow involution (50% by age 5, 70% by 7, 90% by 9)
- •Oral propranolol (2–3 mg/kg/day) is the first-line treatment; mechanism: vasoconstriction + VEGF inhibition + apoptosis; watch for hypoglycaemia
- •Amblyopia is the most important ophthalmic complication - from stimulus deprivation, astigmatism, or strabismus; aggressive patching therapy is essential
- •Kasabach-Merritt phenomenon is NOT associated with infantile hemangioma - it occurs with kaposiform hemangioendothelioma (common exam trap)
