Epidemiology
The annual incidence of open-globe injuries worldwide is estimated to be 203,000 cases. Overall, males comprise approximately 80 percent of open-globe injuries. Males age 10 to 30 are at greatest risk. The chance of blunt globe rupture also increases after some types of ocular surgical procedures, including: large incision cataract removal, cornea transplant, glaucoma filtering, or refractive surgery.
Standardized Terminology2
TERM | DEFINITION |
Open-globe injury | Full-thickness wound of eye wall |
Laceration | Full-thickness wound of the eye wall, caused by a sharp object |
Lamellar laceration | Partial thickness wound of the eye wall |
Rupture | Full-thickness wound of the eye wall, caused by a blunt object |
Penetrating injury | Only entrance wound is present |
Perforating injury | Both an entrance and exit wound are present |

Rapid Overview of Open-Globe Injury Protocol
Based on Mass. Eye and Ear’s experience, we recommend that institutions adopt a standardized management protocol for treating open-globe injuries that consists of a dedicated eye trauma service and 48 hours of intravenous antibiotics.
Preferred Imaging Modality:
Axial and coronal CT of the eye without contrast, utilizing 1 to 2mm cuts through Note: Ocular CT has limited ability to demonstrate an occult open-globe injury and should not be used as the sole determining factor for decisions regarding surgical exploration. |
- Ensure nothing by mouth (NPO)
- Make sure patient has been examined and cleared for life-threatening or systemic injuries
- Avoid high dose ketamine if rapid sequence induction (RSI) is required
- If RSI is necessary, rocuronium is preferred to succinylcholine for muscle relaxation
- Do not remove any protruding foreign bodies until under controlled conditions in an OR
- Avoid eye manipulation that may increase the risk of extrusion of intraocular contents
- Use a new bottle when administering eye drops to patient to ensure drops are sterile
- Place eye shield after initial eye examination
- Put patient on bed rest with head of bed elevated to 30 degrees if hemodynamic condition allows
- Treat nausea and vomiting aggressively (e.g., ondansetron 0.15 mg/kg per dose, up to 12 mg intravenously)
- Provide sedation, as needed (e.g., lorazepam 0.05mg/kg, maximum initial dose: 2 mg)
- Provide analgesia (e.g., IV fentanyl [1mcg/kg per dose, maximum initial dose: 100 mcg] or morphine [0.1 mg/kg per dose, maximum initial dose: 10 mg]
-
Begin IV antibiotics (Transfer of patients with ruptured globes to a tertiary trauma center should not delay the administration of antibiotics.):
- Vancomycin (15 mg/kg IV, maximum dose: 1.5 grams)
- Ceftazidime (50 mg/kg IV, maximum dose: 2.0 grams)
- Fluoroquinolone for penicillin allergic patients (e.g., ciprofloxacin 10 mg/kg IV, maximum dose: 400 mg, use with caution in patients under 18 years of age) - Urgent surgical repair, ideally within 24 hours of injury
Keeping Endophthalmitis Rates Near Zero
The standard Mass. Eye and Ear protocol for eye trauma has resulted in the lowest civilian endophthalmitis rates – less than 1% of cases – reported in the country.
The literature suggests that endophthalmitis rates around the world range from 2.6% to 17%. The United States National Eye Trauma Registry has reported an endophthalmitis rate of 6.9% after open-globe repair.3
