PY - 2017 T2 - Vaughan & Asbury's General Ophthalmology, 19e AB - Orbital disease usually arises within the bony confines of the orbit or by spread from adjacent structures, particularly the paranasal sinuses. The etiology may be inflammation, infection, neoplasia, or vascular anomaly. An orbital mass may also be a metastatic tumor and hence a harbinger of a serious and sometimes life-threatening entity.
