PY - 2011 T2 - Vaughan & Asbury's General Ophthalmology, 18e AB - Orbital disease usually arises within the orbit or by spread from adjacent structures, particularly the paranasal sinuses. The etiology may be inflammatory, due to infection; neoplastic, either benign or malignant and arising from bone, muscle, nerve, blood vessels, or connective tissue; or due to vascular anomalies, including arteriovenous malformations and arterial fistulas. Orbital lesions may also be due to metastatic tumors. Thus, orbital disease may be due to serious and sometimes life-threatening entities.
