Key Points
- Suspect an open globe after penetrating, projectile, high-energy blunt, or metal-on-metal injury even when the external wound is subtle.
- Place a rigid shield and avoid any pressure on the eye.
- Do not perform tonometry, ocular ultrasound, scleral depression, or repeated manipulation when globe integrity is uncertain.
- Do not remove a protruding or impaled object outside the operating room.
- CT orbit is the preferred emergency imaging study for globe contour and radiopaque foreign body; avoid MRI until metal is excluded.
- Give systemic broad-spectrum antibiotics promptly to reduce post-traumatic endophthalmitis risk.
- Control nausea and pain because vomiting and Valsalva can increase extrusion risk.
- Definitive management is urgent surgical repair by ophthalmology.
Algorithm
- Recognize a high-risk mechanism or examination finding suggesting full-thickness ocular injury.
- Stop pressure-producing examination maneuvers and place a rigid eye shield.
- Document visual acuity and pupils gently if possible without manipulation.
- Give analgesia, antiemetic therapy, tetanus prophylaxis as indicated, and keep the patient NPO.
- Start systemic broad-spectrum antibiotic prophylaxis according to local ocular-trauma protocol.
- Obtain thin-cut CT orbits when imaging will not delay emergent surgery; do not obtain MRI until metallic foreign body is excluded.
- Contact ophthalmology immediately and prepare for operative repair.
- After repair, arrange retinal, lens, infection, and visual rehabilitation follow-up.
Clinical Synopsis & Reasoning
An open globe injury is a full-thickness defect of the cornea or sclera from penetrating trauma, blunt rupture, laceration, or intraocular foreign body. Visual loss may be profound or surprisingly mild. High-risk mechanisms include metal-on-metal work, projectiles, sharp objects, explosions, high-energy blunt trauma, and injury in an eye with prior surgery. Findings include peaked or irregular pupil, shallow or deep anterior chamber, uveal prolapse, positive Seidel test, dense subconjunctival hemorrhage, low IOP if measured before suspicion arose, lens disruption, vitreous hemorrhage, or a visible wound or foreign body. A negative Seidel test does not exclude a self-sealed laceration.
Once an open globe is suspected, examination becomes deliberately limited. Avoid any pressure on the eye. Do not perform tonometry, forced eyelid opening, scleral depression, or ocular ultrasound because probe pressure can extrude intraocular contents. Place a rigid shield without a pressure patch. Visual acuity and a gentle pupil examination should be documented if they can be obtained without manipulation. CT of the orbits with thin cuts is the usual imaging study to evaluate globe contour, intraocular air, orbital fractures, and radiopaque intraocular foreign body. MRI is contraindicated until a metallic foreign body has been excluded.
The clinical priorities are to prevent further extrusion, prevent endophthalmitis, control pain and vomiting, and arrange operative closure. A protruding object should remain in place and be stabilized rather than removed in the emergency department. Chemical contamination can require irrigation even in trauma, but suspected globe rupture makes routine irrigation or manipulation unsafe and requires immediate ophthalmology direction.
Treatment Strategy & Disposition
Keep the patient NPO, elevate the head if feasible, place a rigid shield, provide analgesia, and aggressively prevent vomiting or Valsalva with antiemetics. Update tetanus prophylaxis according to wound status. Start systemic broad-spectrum antibiotics as soon as possible. Common adult regimens include IV vancomycin plus ceftazidime or cefepime; a fluoroquinolone-based strategy may be used in selected protocols. Coverage is intended to reduce post-traumatic endophthalmitis, with particular concern for Bacillus after soil-contaminated or high-velocity injuries. Choice and duration should follow ophthalmology and local trauma protocols.
Urgent operative primary repair is the definitive treatment, generally as soon as medically feasible. Surgical goals include watertight closure, restoration of anatomy, management of prolapsed tissue, and planning for lens, retinal, or foreign-body treatment. Intraocular foreign bodies often require vitreoretinal surgery, either at primary repair or in a staged procedure depending on location, composition, infection risk, and resources. Intravitreal antibiotics are considered when contamination, delayed closure, intraocular foreign body, or endophthalmitis risk is high.
Avoid succinylcholine if a suitable alternative exists when concern about transient IOP rise is clinically important, although modern anesthesia practice recognizes that securing the airway safely is paramount and evidence about clinically meaningful extrusion is limited. The more important anesthesia goals are preventing coughing, bucking, vomiting, hypoxia, and hypotension. Postoperative care includes infection surveillance, retinal evaluation, management of traumatic cataract or detachment, and counseling about uncertain final vision.
Epidemiology / Risk Factors
- Open globe injuries occur in occupational, recreational, assault, motor-vehicle, and household trauma.
- Metal-on-metal hammering and grinding are classic mechanisms for small high-velocity intraocular foreign bodies.
- Prior cataract or other ocular surgery can create structurally weaker sites that rupture with blunt trauma.
- Young working-age men are overrepresented in many trauma series, but falls and blunt rupture are important in older adults.
Investigations
| Test | Role / Rationale | Typical Findings | Notes |
|---|---|---|---|
| Visual acuity | Establishes baseline function and prognostic information | Normal to no light perception | Obtain gently without delaying protection or surgery |
| Pupil examination | Assesses afferent defect and structural distortion | Peaked pupil or relative afferent pupillary defect | Avoid excessive manipulation |
| Thin-cut CT orbits | Detects globe contour change, intraocular air, fracture, and radiopaque foreign body | Irregular globe, foreign body, air, hemorrhage | A negative CT does not fully exclude a small laceration |
| Seidel test | Detects aqueous leakage from a small corneal or scleral wound | Fluorescein dilution stream | Do not manipulate an obvious open globe simply to prove the diagnosis |
| CBC, chemistry, coagulation | Preoperative assessment and evaluation of associated trauma | Variable | Target testing to surgical and trauma needs |
Avoid These
| Action | Reason |
|---|---|
| Tonometry | Pressure on an open globe can extrude intraocular contents |
| Ocular ultrasound | Probe pressure can worsen extrusion when globe integrity is uncertain |
| Pressure patch | Compresses the globe; use a rigid shield instead |
| Removal of impaled object | Can release tamponade and cause hemorrhage or extrusion; stabilize for operating-room removal |
| MRI before metal is excluded | A ferromagnetic intraocular foreign body can move in the magnetic field |
| Repeated lid manipulation | Can place pressure on the globe and worsen tissue prolapse |
Pharmacology
| Medication | Mechanism | Onset | Role in Therapy | Limitations |
|---|---|---|---|---|
| IV vancomycin | Gram-positive cell wall inhibition | Hours | Part of common systemic prophylaxis against post-traumatic endophthalmitis | Renal dosing and infusion reactions |
| IV ceftazidime or cefepime | Broad gram-negative beta-lactam activity | Hours | Pairs with gram-positive coverage for systemic prophylaxis | Allergy and renal dosing considerations |
| Ondansetron | 5-HT3 receptor antagonist | Minutes | Prevents vomiting and Valsalva | QT prolongation and constipation |
| Opioid or non-opioid analgesia | Agent-specific analgesic effect | Minutes | Controls pain and reduces squeezing or agitation | Avoid oversedation; NSAID use depends on bleeding and surgical context |
| Tetanus vaccine or immune globulin | Provides active or passive tetanus protection | Days for active immunity; immediate passive protection with TIG | Use according to wound type and immunization history | Not a substitute for wound repair or antibiotic prophylaxis |
Prognosis / Complications
- Presenting visual acuity is one of the strongest predictors of final vision but does not determine outcome by itself.
- Poor prognostic features include afferent pupillary defect, posterior-zone injury, retinal detachment, endophthalmitis, severe tissue loss, and delayed repair.
- Early closure and infection prevention can preserve vision that would otherwise be lost.
- Some eyes require multiple staged surgeries for cataract, retinal detachment, corneal scarring, glaucoma, or reconstruction.
Patient Education / Counseling
- Explain that pressure on the eye can worsen the injury, which is why the examination is intentionally limited and a hard shield is used.
- Prepare the patient for urgent surgery and the possibility that the final visual outcome will not be known immediately.
- Emphasize that a retained foreign body should not be removed outside a controlled surgical setting.
- Review the risk of infection and the reason for systemic antibiotics even when the eye does not look infected yet.
- Provide later prevention counseling about protective eyewear for power tools, grinding, shooting sports, and high-risk work.
Notes
The safest emergency examination is often an incomplete one. Once a credible open-globe mechanism and compatible finding are present, further bedside manipulation can create harm without changing the need for ophthalmology and surgery. The eye should be protected, nausea and pain controlled, antibiotics started, and imaging limited to what safely informs operative planning.
Post-traumatic endophthalmitis prevention is the reason systemic antibiotics are started before there is clinical infection. Regimens vary by institution, contamination, and foreign-body risk, so a reference article should give representative choices while making clear that local ophthalmic-trauma protocols and specialist input determine the final regimen.
