Background
- Vision threatening emergency
- Is a full thickness disruption of sclera or cornea[1]
- Be careful not to apply pressure to eye
- Evert lids with paperclips or eyelid retractors
Causes
- Blunt Eye Trauma
- Caused by suddenly elevated IOP
- Penetrating trauma
- Suspect globe penetration with any puncture or laceration of eyelid or periorbital area
- More commonly associated with objects from metal on metal, lawn mower, drills, grinders[2]
Clinical Features
- Shallow anterior chamber
- Hyphema
- Seidel's sign - do not perform this test if suspect open globe
- May be falsely negative if scleral rupture is small
- Lens dislocation
Differential Diagnosis
Evaluation
- Inspect lids, lashes, cornea, sclera, and pupils.
- Evaluate for a relative afferent pupillary defect
- Visual acuity
- Do NOT perform tonometry for IOP
Work-Up
- Non-contrast CT orbit
- Consider if concern for intraocular foreign body OR diagnosis is unclear
- Sensitivity ~60%
Management[3]
- Consult ophtho immediately for emergent surgical repair
- Prevent further injury
- Do not manipulate the eye
- Eye covering with metal shield (Fox shield) or paper cup (do not place a patch that touches globe)
- Minimize elevations in intraocular pressure
- IV pain medications PRN
- Tetanus prophylaxis (if indicated)
- If intubation necessary, use succinylcholine and ketamine <3mg/kg (do not increase intraocular pressure or cause adverse outcomes)[4]
Disposition
- Admission for surgical repair by ophthalmology
- Transfer to tertiary trauma center if ophthalmologist prefer
