Background
Proptosis in a woman with retrobulbar abscess and orbital cellulitis
- Forward displacement of the eye

- Cavernous sinus thrombosis
- Carotid-cavernous fistula
- Orbital cellulitis
- Mucormycosis
- Orbital fractures
- Orbital hematoma
Evaluation
- Clinical exam (Eye Exam)
- PERRL, EOMI, visual fields
- Assess for diplopia
- Visual acuity
- Intraocular pressure measurement (see Tono-Pen use)
- CT with maxillofacial cuts
- Consider CTA or MRI/MRV
Management
- Management depends of pathophysiology
- Increased IOP may require a lateral Canthotomy
