Orbital trauma
Background
- Must assess:
- Visual acuity
- Anterior chamber
- Integrity of globe
- Pupil shape and reactivity
- Use paperclip or eyelid speculum to open swollen eyes
Clinical Features
- Anterior chamber is flat +/- abnormal pupil
- Ruptured globe is certain
- Stop the exam; place eye shield, consult ophtho
- Hyphema
- Evidence of significant trauma; consult ophtho
- Extra-ocular movements
- Restricted upgaze or lateral gaze suggests Orbital Fracture with entrapment
- Obtain CT face
- Restricted upgaze or lateral gaze suggests Orbital Fracture with entrapment
- Orbital Rim
- Feel for step-off
- Sensation
- Test along distribution of inf orbital nerve (below eye and ipsilateral side of nose)
- Photophobia
- If photophobia in affected and unaffected eye, suspect traumatic iritis
- Decreased visual acuity +/- proptosis
- Clinically suspect Orbital Hematoma, check IOP if open globe has been ruled out

^Emergent diagnoses ^^Critical diagnoses
Evaluation
- Slit-lamp exam with fluorescein
- Check for:
- Abrasion
- Laceration
- Ulceration
- Foreign body
- Hyphema
- Hypopion
- Iritis
- Lens dislocation
- Globe rupture
- Check for:
- Consider non-contrast face/orbital CT
- Consider ocular ultrasound (if no suspicion for globe rupture)
Management
- Based on specific injury
Disposition
- Depends on specific injury
