The recent International Society for the Study of Vascular Anomalies (ISSVA) classification of vascular anomalies can be applied to orbital lesions, dividing them into vascular tumors and vascular malformations. Orbital cavernous hemangiomas are probably best considered cavernous venous malformations under this classification. Management of symptomatic lesions can be with surgical excision or stereotactic fractionated radiotherapy in selected cases. Beta-blockers including propranolol and topical timolol maleate represent first-line therapy for infantile hemangiomas, although surgery has a role in selected cases. Orbital venous-lymphatic malformations are problematic but with improved imaging, neuroradiological intervention, and a multidisciplinary approach to management, outcomes are improving.

UI	MeSH Term	Description	Entries
D009915	Orbit	Bony cavity that holds the eyeball and its associated tissues and appendages.	Eye Socket,Eye Sockets,Orbits,Socket, Eye,Sockets, Eye
D009918	Orbital Neoplasms	Neoplasms of the bony orbit and contents except the eyeball.	Neoplasm, Orbital,Neoplasms, Orbital,Orbital Neoplasm
D006391	Hemangioma	A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE.

D006392	Hemangioma, Cavernous	A vascular anomaly that is a collection of tortuous BLOOD VESSELS and connective tissue. This tumor-like mass with the large vascular space is filled with blood and usually appears as a strawberry-like lesion in the subcutaneous areas of the face, extremities, or other regions of the body including the central nervous system.

D054079	Vascular Malformations	A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.	Malformation, Vascular,Malformations, Vascular,Vascular Malformation
