Penetrating eye injuries in the field: what to do and why not to apply pressure

Which of the following is NOT a step when treating a penetrating eye injury?

• A. Conduct a rapid visual acuity test
• B. Cover the eye with a rigid eye shield
• C. Apply pressure to the eye
• D. Conduct CWMP

Answer: (C)

When addressing a penetrating eye injury, it is crucial to follow specific steps to prevent further damage and manage the injury effectively. The step of applying pressure to the eye is not appropriate in this scenario. Doing so can exacerbate the injury by forcing more contents into the eye or causing more trauma to the already injured area. Conducting a rapid visual acuity test is important for assessing the extent of the injury and determining the necessary interventions. Covering the eye with a rigid eye shield protects the injured eye from additional trauma and helps stabilize the injury. Conducting CWMP (Control of the Wound Management Protocol) assists in managing the overall care of the patient. In contrast, applying pressure can lead to further complications, which is why this action is not recommended when treating penetrating eye injuries.

Eye injuries in the heat of battle are nothing short of brutal. In Tactical Combat Casualty Care, the way you handle an eye wound can mean preserving sight or losing a crucial sense at a moment when every sense matters. When a penetrating eye injury lands in the field, there’s a small, essential playbook you can rely on. The central idea is clear: rapid assessment, smart protection, and disciplined management. Three steps—no more, no less—guide you toward stabilizing the patient while you arrange for faster transfer to higher care.

Let me walk you through the steps with a practical feel, not a textbook vibe. Think of it as a quick, calm routine you can run through even when the adrenaline is high.

Rapid Visual Acuity Test: a quick map of what you’re dealing with

Here’s the thing about penetrating eye injuries: you want to know how badly vision is affected, but you don’t want to press or poke. A rapid visual acuity test gives you a snapshot without traumatizing the eye further. In the ideal setup, you’d compare vision in the injured eye to the uninjured eye. If you have a Snellen chart or a makeshift chart, great—that’s your lane. If not, even a simple count of fingers or close-range reading can establish a baseline.

A few practical tips:

• Have the patient keep both eyes closed briefly, then open the uninjured eye while you observe their response. This helps you gauge immediate function without introducing unnecessary movement around the wound.

• If the injured eye can respond to light, note it. If there’s no response, that’s a red flag that requires urgent escalation.

• Document the result clearly, but don’t linger. The goal is to know enough to guide transport decisions and protect the eye while you move.

Why this step matters: a quick acuity check informs your priorities. It helps you decide if the patient needs faster evacuation, additional medical support, or specific protective measures. It’s not about a perfect score; it’s about a usable read on function in the moment.

Cover the eye with a rigid shield: the quiet guardian

Now the big move: protect the eye without pressing on it. A rigid eye shield is your best friend here. The shield acts like a gentle, firm cap that stops elbows, debris, or accidental pressure from turning a fragile injury into a catastrophe. The principle is simple: shield, don’t squeeze.

What to use and how to apply:

• If you have an actual sterile eye shield, place it over the closed eyelids and secure it lightly so it stays in place. The key is to avoid pressing on the eyeball itself.

• If a proper shield isn’t available, a rigid, clean substitute—like a cup or a compact, rigid protective barrier—can be improvised. The goal is the same: a barrier that keeps pressure off the eye while the patient moves.

• Do not apply tape directly over the eye in a way that pinches or compresses the globe. And never patch the eye with fabric that puts direct pressure on the eyeball.

Why not just wrap a bandage tightly? A firm wrap around the head may stabilize the face, but the eye itself needs an inert but solid cover. Pressure from any angle can push contents around or worsen a perforation, so the shield is a non-negotiable step in this scenario. It’s a calm, protective gesture that buys time without risking more harm.

CWMP: Control of Wound Management Protocol—the field care spine

CWMP stands for Control of Wound Management Protocol, and it’s the framework that keeps field care organized and effective. For a penetrating eye injury, this protocol isn’t about heroic one-off maneuvers; it’s about steady, prioritized actions that reduce risk and improve outcomes as you move toward definitive care.

Key elements you’ll typically run through under CWMP:

• Airway, breathing, circulation: make sure the patient is stable and comfortable. Let them breathe, monitor for signs of distress, and maintain a clear airway as you prepare for evacuation.

• Wound protection: the rigid shield stays in place, protecting the eye while you manage the rest of the scene. Avoid anything that might apply pressure to the eye.

• Contamination control: minimize exposure to dirt and debris. Do not attempt to irrigate a penetrating eye wound in the field unless you’re trained and the situation clearly calls for it. The risk is that irrigation can force contaminants deeper or disturb a fragile globe.

• Pain management and comfort: provide simple analgesia if available and appropriate, along with reassurance. A calm patient stabilizes the fight-or-flight response, which helps you manage the scene more effectively.

• Evacuation plan: CWMP emphasizes rapid, safe transfer to a higher level of care. Time is precious, but speed must be paired with stability.

CWMP isn’t a single move; it’s the rhythm you keep as you move from the scene to the field care corridor. It aligns your actions with the bigger goal: preserve life and, where possible, preserve vision.

What about the move that isn’t a move? Why pressure isn’t a step

If you’re doing eye care in the field long enough, you’ll encounter questions like, “Couldn’t applying gentle pressure control bleeding and stabilize the eye?” It’s a logical thought, but for a penetrating eye injury, it’s precisely the action to avoid. Pressing on the eye can push material into the eye, worsen a perforation, or cause additional trauma to the delicate tissues inside.

Let me spell that out with a quick contrast:

• Pressure on the eye: risks pushing contents deeper, increasing damage, and potentially complicating surgical repair later. It’s like trying to squeeze a fragile seed pod without knowing what’s inside—bad idea in a live injury.

• Visual acuity test: a safe, informative check that helps you gauge severity without touching the injury in a risky way.

• Rigid shield: a protective barrier that reduces further trauma while you stabilize and evacuate.

• CWMP: a coordinated approach that treats the wound as part of the whole patient, not as a solitary problem.

The point is simple: you’re aiming to prevent further harm, not to compress or manipulate an already compromised globe. That restraint is a mark of good field care, not a failure to act.

A few practical digs and real-world tangents

I won’t pretend this is only a theoretical exercise. In the real world, you’ll often juggle two realities at once: you’re trying to stabilize the patient, but you’re also safeguarding your teammates and the mission. That’s where the human side of TCCC shows up.

• Communication matters. Clear, brief handoffs with the receiving medical team shorten the time to advanced care. If you’re working with a buddy aid kit, keep your language tight and your expectations realistic.

• Documentation isn’t glamorous, but it’s critical. A quick note about the initial visual acuity and the shield’s placement can save minutes later, which translates into better outcomes.

• Training drills matter more than you might guess. Rehearsing the sequence—test vision, shield the eye, run CWMP—helps you perform under pressure when the situation shifts from “routine pain” to “urgent evacuation.”

• It’s okay to be methodical. In high-stakes scenes, a deliberate, calm approach often beats raw speed. Method wins when chaos looms.

A few caveats you’ll hear in the field

• Do not remove any object that is penetrating the eye unless you’re in a controlled medical setting with trained personnel. Removing the object at the wrong moment can cause catastrophic damage.

• If the patient has a penetrating eye injury with suspected globe rupture, avoid any manipulation that might change the position of the globe. Keep the eye protected and stable.

• Antibiotic prophylaxis and tetanus considerations are part of broader care planning. When available, they’re part of the steps that help prevent infection while you’re en route to definitive care.

The big takeaways

• A penetrating eye injury in a tactical setting is handled best with three core steps: a rapid visual acuity check, protection with a rigid eye shield, and a structured management approach via CWMP.

• Pressure on the eye is not part of the treatment. In fact, it’s something to actively avoid because it can worsen the injury.

• The shield is more than a shield; it’s a strategic decision that reduces further trauma while you stabilize and evacuate.

• CWMP ties all the actions together, focusing on the patient’s overall status, protection of the wound, and smooth transfer to higher care.

If you’re curious about how this fits into a broader skill set, take a moment to connect the dots. Eye injuries aren’t just a single bullet in a manual; they’re a test of situational awareness, gentle hands, and clear thinking under pressure. The steps you memorize become habits you instinctively lean on when a scene turns chaotic. And that confidence—born from practice, not bravado—can be the difference between a sight-saving intervention and a missed opportunity.

So, next time you review a field care scenario or run through a drill, keep these three moves in your pocket. They’re compact, practical, and designed to stand up when the going gets tough. If you’re ever unsure, the simplest question can guide you: What helps the patient right now without risking more harm? The answer usually lands in the form of a shield over a careful eye, a quick, honest acuity check, and a steady plan for moving the patient toward advanced care.

In the end, it’s about respect for the eye’s fragility and respect for the chain of care that follows the scene. The field is unforgiving, but with this approach, you keep sight and safety front and center, every step of the way.
