The orbit contains, protects and supports the eye and surrounding structures, including the nerves, blood vessels, muscles, and glands. The orbit is encased in 7 bones that provide structural support and protection. Orbital diseases can be benign or malignant, and include inflammatory, vascular, structural, or neoplastic disorders.
Signs of orbital disease include proptosis (protrusion of the eye), double vision, pain, swelling, pain with eye movement, dilated blood vessels, and masses around the eye and eyelids.
The goal of an orbital evaluation is to identify the cause of the condition and its location, including systemic causes (e.g. tumor metastasis or inflammatory disease).
Some common diagnoses of orbital disease include (not a complete list):
- Thyroid eye disease (also known as thyroid or Graves associated orbitopathy
- Orbital fracture
- Cavernous hemangioma (vascular anomaly behind the eye)
- Orbital cellulitis (infection of the orbit, often associated with sinus infection)
- Benign orbital inflammation (often associated with systemic rheumatologic disease)
- Dacryoadenitis (inflammation of the lacrimal gland)
- Lymphangioma and venous anomalies (abnormal blood vessels)
- Benign tumors (e.g. pleomorphic adenoma, lipoma)
- Primary orbital cancer (e.g. rhabdomyosarcoma, adenoid cystic carcinoma)
- Metastasis of cancer (e.g. breast cancer)
