Pre-Ophthalmologist Management of Eye Trauma

This phrase means what to do before an eye specialist (ophthalmologist) sees the patient. It includes the very first steps at home, in the field, in an ambulance, or in an emergency department triage area. The goal is simple: save life first, then save sight, while doing no harm to the injured eye. This stage is about safe triage, gentle exam, protection of the eye, pain and nausea control, and fast transfer to the right place for definitive care. A careful, step-by-step approach helps non-specialists spot danger quickly and avoid actions that can worsen the injury. EyeWiki

This is the first-aid and early care you give to an injured eye while you are still at home, at work, on the field, or in an emergency department before an ophthalmologist sees the patient. It includes safe actions (like irrigation for chemicals, shielding for penetrating injury, and gentle pain control) and strict “do-not-do” rules (no rubbing, no pressure, no contacts, no topical anesthetic kept at home, and no trying to remove embedded objects). The purpose is to protect the eye’s structures, limit infection and inflammation, keep the cornea moist, and reduce complications such as worsening bleeding, higher eye pressure, or deeper chemical penetration. It also means knowing the red flags that demand an immediate emergency visit (for example, sudden vision loss, chemical splash, object stuck in the eye, severe pain, blood in the front of the eye, double vision after trauma, or the sensation of “something exploded” in the eye).

Universal First Steps (for most eye injuries)

Stop and look. Do not rub. Wash hands. If the injury is a chemical splash, start flushing immediately with clean water or saline for at least 15–30 minutes, keep the eye open while irrigating, and remove contact lenses during irrigation if they come out easily. If you suspect a penetrating injury (a sharp object, high-speed projectile, metal on metal, shattered glass), do not press the eye, do not pull out anything, gently place a rigid shield (the bottom of a paper cup works) and seek emergency care. For dust or small particles, blink and use sterile saline or clean running water to rinse. Avoid topical anesthetic drops at home: they can damage the cornea if misused. Avoid ointments before a doctor looks if you suspect a serious injury, because they can blur the view and trap particles. Give simple oral pain relief like acetaminophen if needed and safe. Arrange urgent eye care.

Core safety rules you should follow every time

1) Follow ABCDE trauma priorities. Check airway, breathing, and circulation first. Treat life-threats before eye-threats. Then protect the injured eye. This order prevents vision care from distracting you from lifesaving care. Oxford Academic

2) Do not press on the eye. If a globe (eyeball) is open or may be open, any pressure can push eye contents out and cause permanent vision loss. Do not patch with pressure. Do not bandage. Do not put gauze under the shield. Use a rigid eye shield that touches the bones around the eye and not the eye itself. jts.health.milWebEye

3) For chemical burns, irrigate immediately and continuously. Start irrigation at once with clean water or saline. Keep irrigating during transport. Check eye surface pH and continue until it is back to normal. If available, a Morgan lens can help provide continuous irrigation. Irrigation takes priority over a detailed eye exam. EyeWikiMedscapeJEMSLippincott Journals

4) Be cautious with testing. Some tests can worsen an open globe. Avoid tonometry and avoid ocular ultrasound if you suspect globe rupture. Prefer non-contrast CT of the orbits when you need imaging. Avoid MRI if a metal foreign body is possible. American Academy of OphthalmologyACEP+1NCBI

5) Control pain and vomiting. Pain and vomiting can increase eye pressure and make injuries worse. Give safe analgesia and an antiemetic when needed, and keep the patient NPO (nothing by mouth) if you think surgery is likely. (Local protocols apply.)

6) Update tetanus when appropriate and arrange rapid ophthalmology follow-up or transfer as soon as the patient is stable. PMC

Types of eye trauma

1) Blunt eye injury (contusion). A ball, fist, or airbag hits the eye. The eye can swell, bleed, or develop a hyphema (blood in the front chamber). Shield the eye, avoid pressure, check vision gently, and refer. WebEye

2) Open globe injury (penetrating or ruptured eyeball). A sharp object, high-speed chip, or severe blunt force opens the eyewall. Clues are a “teardrop” pupil, deep pain, poor vision, or tissue protruding. Do not touch the eye. Do not put drops. Do not do tonometry. Place a rigid shield and get urgent imaging and transfer. WebEyeAmerican Academy of Ophthalmology

3) Intraocular foreign body (IOFB). A tiny metal or glass fragment can lodge inside the eye after drilling, grinding, or explosions. Do not remove any protruding object. Shield and arrange urgent CT orbits. American Academy of Ophthalmology

4) Superficial corneal foreign body. Dust, sand, or a small lash sits on the cornea. If you are not trained, avoid scraping. Use irrigation, evert the lid to look for hidden particles, stain with fluorescein if safe, and refer if symptoms persist. Agency for Clinical Innovation

5) Chemical injury (alkali or acid). Alkali burns penetrate deeply and act fast; acids also damage the surface. Start irrigation immediately and keep irrigating. Check pH and keep irrigating until normal. Continue irrigation during transport. EyeWikiMedscape

6) Thermal burn. Heat or flame damages lids and ocular surface. Cool the area (not ice directly on the globe), protect the cornea with a shield, and refer. (Follow local burn care protocols.)

7) UV/radiation injury (e.g., welding arc). Pain and light sensitivity appear hours later. Shield from light, provide analgesia, and arrange follow-up. (Avoid topical anesthetic for home use.)

8) Eyelid laceration. Cuts may involve lid margin or tear ducts. Do not clamp or press. Cover gently without pressure and refer for specialist repair. Agency for Clinical Innovation

9) Orbital fracture. Blunt trauma can break the bone around the eye, causing double vision, sunken eye, or numb cheek. Avoid nose-blowing, shield the eye, assess extra-ocular movements, and get CT as needed. rcemlearning.co.uk

10) Retrobulbar hemorrhage (bleeding behind the eye). This is rare but vision-threatening. Signs are severe pain, proptosis, tight lids, rock-hard orbit, and decreasing vision. Treat as an emergency; urgent ophthalmology evaluation is needed. Agency for Clinical Innovation

11) Corneal abrasion. The clear surface is scratched. Confirm with fluorescein if globe is closed, provide pain control, and refer if large, central, or due to high-risk mechanism. rcemlearning.co.uk

12) High-pressure injection injury (paint/grease). Tiny entry wound, severe internal damage. Shield and urgent transfer. Agency for Clinical Innovation

13) Combined head and eye trauma. Manage life threats, then protect the eye. Consider CT head and orbits when indicated. Do not delay stabilization to do a full eye exam. Oxford Academic

14) Contact-lens associated surface injury after trauma. Remove lenses during irrigation, especially in chemical burns. Do not reinsert. Medscape

15) Suspected globe rupture with swelling that hides the eye. Do not force eyelids open. Do not ultrasound. Shield and image with CT. ACEPAmerican Academy of Ophthalmology

Common causes

1. Sports balls and bats. Fast-moving balls and equipment can hit the eye directly.

2. Fists and interpersonal violence. Punches cause blunt force and fractures.

3. Falls. A fall onto furniture or the ground can injure the eye and orbit.

4. Road traffic crashes. Airbags, dashboards, or glass can strike the eye.

5. Power tools and grinding. Tiny metal chips fly into the eye at high speed.

6. Hammering and chiseling metal. Small fragments can penetrate deeply.

7. Construction debris and dust. Sand and chips scratch the cornea.

8. Chemicals at work or home. Alkalis (like lye) or acids splash into the eye. EyeWiki

9. Battery explosions or fireworks. Pressure and chemicals cause combined injuries.

10. Cooking oil splashes. Hot oil burns the lids and surface.

11. Welding without eye protection. UV light injures the cornea (welder’s flash).

12. Garden work (twigs, thorns). Sharp plant parts can cut the eye.

13. Animal scratches or pecks. Cat claws or bird pecks can penetrate.

14. High-pressure paint or grease guns. Material is injected into the tissues.

15. Industrial solvents or cleaning agents. Strong solutions cause chemical burns. Agency for Clinical Innovation

16. Fire and thermal burns. Heat damages lids and surface.

17. Explosions (occupational or conflict). Shrapnel and blast pressure harm the eye. staging-mobile.health.mil

18. Glass shards. Breaking glass can send sharp pieces into the eye.

19. BBs, pellets, or rubber bullets. Small, fast projectiles can perforate the globe.

20. Diving/pressure changes. Rapid pressure shifts can injure the orbit and sinuses.

Symptoms patients may report

1. Eye pain. Pain suggests surface injury, deeper damage, or high pressure.

2. Blurred or lost vision. Any drop in vision is a red flag and needs urgent care.

3. Light sensitivity (photophobia). Often seen with corneal injuries and uveitis.

4. Tearing and watering. The eye tries to flush out a foreign body or soothe the surface.

5. Foreign-body sensation (gritty feeling). Common with abrasions and small particles.

6. Redness. Surface irritation, bleeding, or inflammation.

7. Double vision. May indicate muscle entrapment or nerve injury after fracture.

8. Flashes or floaters. Can suggest vitreous hemorrhage or retinal problems after trauma.

9. Halos around lights. Can occur with corneal edema after blunt injury or chemical burn.

10. Headache. Common with eye strain, fractures, or combined head trauma.

11. Nausea and vomiting. Worrying because it can raise eye pressure and worsen injury.

12. Eyelid swelling and bruising. Often from blunt impact or fracture.

13. Bleeding from the eye or lids. Suggests laceration or open globe.

14. Difficulty opening the eye. Due to pain, swelling, or nerve injury.

15. Numb cheek or teeth pain. May indicate infra-orbital nerve injury with orbital floor fractures. rcemlearning.co.uk

Diagnostic tests before the ophthalmologist sees the patient

Below are 20 tests grouped by category. For each, I explain what it is, how to do it safely, and why it helps. I also note key do-not-do warnings where harm is possible.

A) Physical exam tests

1) Visual acuity (VA).
What it is: A quick vision test using a Snellen chart, near card, or counting fingers.
How to do it safely: Test each eye separately; shield the injured eye without pressure if needed. If lids cannot open, do light perception vs no light perception.
Why it helps: VA is the vital sign of the eye and guides urgency and prognosis. PMC

2) Pupils: size, shape, and light response.
What: Check direct and consensual responses. Look for an irregular or “teardrop” pupil that points to a wound.
Safety: No pressure on the globe while opening lids.
Why: Abnormal pupils suggest open globe, intraocular bleeding, or optic nerve issues. WebEye

3) External inspection of lids, lashes, and conjunctiva.
What: Gently look for lacerations, burns, swelling, or foreign bodies on the surface.
Safety: Do not press on a suspected open globe. If there is deep, obvious injury, shield and stop.
Why: External signs often point to the internal problem and dictate urgency. Agency for Clinical Innovation

4) Extra-ocular movements (EOMs).
What: Ask the patient to look up, down, left, and right.
Safety: If movement is very painful or there is crepitus or obvious deformity, stop and image.
Why: Pain, restriction, or double vision can mean muscle entrapment from an orbital floor fracture. rcemlearning.co.uk

5) Confrontation visual fields.
What: Compare the patient’s side vision to yours.
Safety: Keep it brief; do not delay more urgent actions.
Why: Field loss can reflect optic nerve or brain injury after trauma.

6) Vital signs and brief neuro check (GCS).
What: Blood pressure, pulse, breathing, and mental status.
Why: Head injuries and shock take priority. This also guides safe transfer and analgesia. Oxford Academic

B) Manual bedside tests

7) Upper eyelid eversion (to look for hidden particles).
What: Gently flip the upper eyelid to look in the upper pocket where particles often hide.
Safety: Do not do this if you suspect an open globe.
Why: Removing hidden debris prevents ongoing scratching and pain. Agency for Clinical Innovation

8) Fluorescein staining of the cornea.
What: A dye highlights scratches and defects under blue light.
Safety: Only if the globe is closed. If you suspect an open globe, do not stain—shield and refer.
Why: Helps confirm abrasions, foreign-body tracks, and edge of epithelial defects. rcemlearning.co.uk

9) Seidel test (to detect fluid leak).
What: After fluorescein, a streaming of dye shows aqueous humor leaking from a full-thickness wound.
Safety: Do not perform if there is obvious globe rupture or full-thickness laceration; shield and refer.
Why: A positive Seidel test confirms open globe. NCBI

10) Ocular surface pH testing (for chemical burns).
What: Touch pH paper to the tear film to check acidity/alkalinity.
Safety: Test after starting irrigation and recheck until pH returns to normal.
Why: The goal is to normalize pH; it guides how long you irrigate. MedscapeemDocs

11) Gentle palpation of orbital rim for step-offs and crepitus.
What: With very light touch on the bony rim (not the globe), feel for deformity or crackling air.
Safety: Skip this if it hurts a lot or if swelling is severe. Never press the eyeball.
Why: Suggests an orbital fracture and the need for CT. rcemlearning.co.uk

C) Lab and pathological tests

12) Complete blood count (CBC).
What/Why: Helpful when there is significant bleeding (e.g., hyphema), suspected infection, or surgical planning.

13) Coagulation profile (PT/INR, aPTT).
What/Why: Important if the patient is on blood thinners or has a bleeding tendency, especially with hyphema or planned surgery.

14) Sickle cell screening when hyphema is present and risk is high.
What/Why: Sickle cell disease or trait changes hyphema management and risks; early awareness assists safe planning.

D) Electrodiagnostic tests — usually after stabilization, not in the field

15) Visual evoked potential (VEP).
What: Measures brain response to light to assess the optic pathway.
Why: Occasionally helps when the view is blocked or the exam is unreliable after severe injury.

16) Electroretinography (ERG).
What: Measures retina’s electrical response to light.
Why: Helps when retinal function is unclear after trauma such as severe contusion or hemorrhage.

(These two are not routine prehospital tests, but they are part of the broader diagnostic toolbox once the patient is stable and with specialist input.)

E) Imaging tests

17) Non-contrast CT of the orbits.
What: The preferred initial imaging for suspected open globe, orbital fracture, or intraocular foreign body.
Why: Shows fractures and metal/glass fragments; fast and widely available.
Notes: Use non-contrast; contrast is not needed. American Academy of Ophthalmology

18) CT head and maxillofacial sinuses.
What/Why: Added if you suspect brain injury or complex facial fractures along with the eye injury. American Academy of Ophthalmology

19) Ocular ultrasound (B-scan).
What: Bedside ultrasound can detect retinal detachment, vitreous hemorrhage, and lens dislocation.
Safety: Avoid if you suspect an open globe; pressure from the probe can worsen the injury. If used by trained staff and rupture is unlikely, gel over a closed eyelid with very light touch is standard. ACEP+1

20) MRI of the orbits/brain (selected cases only).
What: Useful for soft-tissue detail when there is no metal.
Safety: Contraindicated if a metallic foreign body is possible. Use CT instead. NCBI

Non-Pharmacological Treatments (Therapies & Other Measures)

1. Immediate Chemical Irrigation
   Purpose: dilute and remove the chemical fast to stop deeper burns.
   Mechanism: large volumes of water or saline physically wash away acid/alkali; this rapidly moves the eye’s surface pH toward normal. Keep irrigating for 15–30 minutes or until a clinician confirms normal pH.

2. Eye Shielding (Rigid Cup Shield)
   Purpose: protect against pressure and accidental touching when the globe might be open.
   Mechanism: a rigid barrier (not a pressure patch) prevents lids or fingers from pressing on the eyeball and pushing out tissue.

3. No-Pressure “Hands-Off” Rule
   Purpose: avoid making a hidden rupture worse.
   Mechanism: pressure can extrude eye contents; avoiding it preserves anatomy until surgical repair.

4. Blinking and Sterile Saline Rinse for Minor Debris
   Purpose: remove loose particles without scraping the cornea.
   Mechanism: tears plus sterile saline flow wash the foreign body away while preserving the epithelial surface.

5. Contact Lens Removal (If Easy, Non-Traumatic Case)
   Purpose: stop the lens from trapping chemicals or microbes.
   Mechanism: removing the lens improves oxygenation and allows irrigation to reach the cornea. If stuck or painful, don’t force it—seek care.

6. Cold Compress (Closed Lids Only)
   Purpose: reduce swelling and bruising after blunt injury.
   Mechanism: cooling narrows blood vessels and reduces inflammatory swelling. Do not press the eyeball.

7. Head Elevation
   Purpose: reduce pressure and swelling, especially if bleeding (hyphema) is suspected.
   Mechanism: gravity helps blood settle and lowers venous pressure.

8. Light Avoidance / Sunglasses
   Purpose: reduce photophobia (light sensitivity) and pain.
   Mechanism: less light means less ciliary muscle spasm and less discomfort.

9. Activity Restriction
   Purpose: prevent re-bleeding or pressure spikes after trauma.
   Mechanism: avoiding heavy lifting, straining, or sports reduces Valsalva-related pressure.

10. Tear Film Support with Sterile Lubricating Drops (Non-Medicated)
    Purpose: keep the cornea moist if the surface is irritated.
    Mechanism: artificial tears dilute inflammatory molecules and create a protective film. Avoid preserved drops if using frequently.

11. Do Not Patch for Most Corneal Abrasions
    Purpose: avoid a warm, dark, moist environment where bacteria can thrive.
    Mechanism: modern care favors lubrication and, when prescribed, antibiotic ointment—not pressure patches.

12. Avoid Eye Makeup and Contaminated Water
    Purpose: reduce infection risk.
    Mechanism: cosmetics and pools/lakes can carry microbes that infect a wounded cornea.

13. Remove Obvious Loose Eyelid Debris with Clean Water Only
    Purpose: gently clear grit from lashes.
    Mechanism: minimizes eyelid-to-cornea friction without rubbing.

14. Stop Contact Lens Use Until Cleared
    Purpose: prevent infection over a healing cornea.
    Mechanism: lenses reduce oxygen and can carry bacteria, especially Pseudomonas.

15. Pain Coping: Dark Room, Rest, Guided Breathing
    Purpose: reduce sympathetic stress and squeezing of the eyelids.
    Mechanism: relaxation lowers muscle tension and perceived pain.

16. Avoid Aspirin if Active Bleeding Suspected
    Purpose: reduce bleeding risk in blunt trauma with hyphema.
    Mechanism: aspirin’s platelet effect can worsen bleeding. Choose acetaminophen unless told otherwise.

17. Keep the Eye Dry and Clean
    Purpose: reduce microbial growth on the lids and lashes.
    Mechanism: gentle lid hygiene supports a healthier tear film during recovery.

18. Do Not Try to Remove Embedded Objects
    Purpose: avoid pulling on tissue or causing perforation.
    Mechanism: foreign bodies may be plugging a hole; removal can open it.

19. Bring the Chemical Container or Metal Type to the ER
    Purpose: helps clinicians identify the agent and choose specific therapy.
    Mechanism: knowing the pH, ingredients, or metal type guides treatment.

20. Early, Appropriate Referral
    Purpose: get specialized tools (slit lamp, fluorescein, tonometry) and treatments quickly.
    Mechanism: faster expert care improves healing and lowers complications.

 Surgeries/Procedures

1. Primary Globe Repair
   Procedure: surgical closure of corneal/scleral lacerations under the microscope; removal of non-self-sealing foreign bodies; antibiotics and protective measures.
   Why: restore the eye’s integrity, prevent infection, and preserve vision after an open-globe injury.

2. Lateral Canthotomy/Cantholysis (Emergency Decompression)
   Procedure: small lateral eyelid incision at bedside in the ER to release pressure inside the orbit.
   Why: treat orbital compartment syndrome from bleeding/swelling that threatens the optic nerve and vision within minutes.

3. Amniotic Membrane Transplantation (AMT)
   Procedure: biologic graft placed on the cornea/conjunctiva and secured with sutures or glue.
   Why: promote epithelial healing and reduce scarring/inflammation after severe surface burns or large abrasions.

4. Temporary Tarsorrhaphy
   Procedure: partially sewing eyelids together to protect the cornea.
   Why: shield a non-healing surface, reduce exposure, and improve lubrication while the epithelium recovers.

5. Limbal Stem Cell Transplantation (e.g., SLET/CLET)
   Procedure: transplant of stem-cell–rich limbal tissue from the patient or a donor to rebuild the corneal surface in severe chemical burns.
   Why: restore a stable, healthy epithelium when native limbal cells are destroyed.

Preventions

1. Wear ANSI-rated safety goggles for grinding, drilling, mowing, or chemicals.

2. Use face shields for high-velocity work or caustic liquids.

3. Store chemicals high, closed, and labeled; keep sprayer nozzles pointed away.

4. Never mix cleaners (e.g., bleach + ammonia).

5. Use sports goggles for racquet sports, baseball, and basketball.

6. Fireworks: observe only; if handling, use eye shields and follow local laws.

7. In the car: seatbelts on; keep objects off dashboards.

8. Keep nails trimmed and avoid rubbing eyes.

9. Contact lens hygiene: no sleeping in lenses unless prescribed; no lenses in pools/hot tubs.

10. Teach children to ask an adult before using sprays or sharp objects.

---

When to See a Doctor—Right Now vs. Soon

Go to emergency care immediately (today): sudden vision loss, chemical splash, object stuck in the eye, suspected cut or puncture, severe pain, new double vision, blood layering in the front of the eye (a “red fluid level”), significant light sensitivity, or a feeling that the eye is “full” or under pressure.
See an eye doctor within 24 hours: persistent foreign-body sensation, moderate pain that doesn’t improve, worsening redness, discharge, or blurry vision after a minor injury.
Stop contact lenses and bring information (chemical bottle, metal type, injury details).

What to Eat” and “What to Avoid” During Recovery

1. Eat: lean proteins (fish, eggs, legumes) to supply amino acids for tissue repair.

2. Eat: colorful produce (spinach, kale, carrots, blueberries) for vitamins A, C, lutein, and antioxidants.

3. Eat: omega-3 sources (salmon, sardines, flax/chia) to support the tear film.

4. Eat: citrus and bell peppers for vitamin C to help collagen cross-linking.

5. Eat: nuts/seeds (almonds, sunflower seeds, pumpkin seeds) for vitamin E and zinc.

6. Avoid: smoking and secondhand smoke—they slow healing and dry the eyes.

7. Avoid: heavy alcohol—dehydrates and impairs sleep and immune function.

8. Avoid: high-sugar ultra-processed snacks—can promote inflammation.

9. Avoid: very spicy or salty foods close to bedtime if they worsen dry mouth/eyes.

10. Avoid: unclean water and contact lenses while healing—reduces infection risk.

Frequently Asked Questions

1) Should I rinse with tap water if I have no saline?
Yes. Any clean water now is better than waiting. Start flushing immediately for chemical injuries.

2) Can I use numbing drops I got once in the ER?
No. Home use of topical anesthetics can slow healing and damage the cornea. They are for in-clinic use only.

3) Do I patch my eye after a scratch?
Usually no. Patching can trap bacteria and increase infection risk. Follow your doctor’s instructions.

4) How do I know if my eye is “ruptured”?
Severe pain, sudden vision drop, irregular or peaked pupil, or a history of high-speed object injury suggest it. Shield the eye and go to the ER.

5) I got bleach in my eye. When can I stop rinsing?
Rinse 15–30 minutes continuously, then get checked. In clinic, staff may test the pH and continue irrigation until it’s normal.

6) Is redness alone an emergency?
Not always, but redness plus pain, light sensitivity, or vision change after trauma is urgent.

7) Can I take ibuprofen?
If there’s no suspected bleeding (like hyphema) and your doctor says it’s safe for you, short-term ibuprofen can help. Otherwise choose acetaminophen.

8) When can I wear contacts again?
Only after your eye doctor confirms the surface is healed and infection risk is gone.

9) Are “natural tears” the same as medicated drops?
No. Artificial tears lubricate but do not treat infection or severe inflammation. They are supportive.

10) Will blue-light glasses help after trauma?
They may reduce light discomfort. They don’t change healing, but comfort matters.

11) Do I need antibiotics for every scratch?
Small, clean, non–contact-lens abrasions often get prophylactic ointment. Contact-lens–related injuries or dirty wounds need broader coverage as directed by a clinician.

12) Can I drive after eye drops?
Many drops blur vision temporarily. Do not drive until your vision is safe.

13) My child poked their eye with a pencil—what now?
If pain, tearing, or light sensitivity continue, seek urgent care. Do not press the eye; consider a gentle shield.

14) Will vitamins fix my eye injury?
Vitamins support healing but do not replace proper medical treatment. Use them as adjuncts, not cures.

15) How fast should I expect improvement?
Minor abrasions may improve in 24–48 hours. Chemical burns, deep cuts, or bleeding need specialist care and can take weeks. Early expert treatment improves outcomes.
