What is the urgent management for a 52‑year‑old woman presenting with left eye pain, redness, tearing, deep retro‑orbital discomfort, and a foreign‑body sensation?

Immediate Ophthalmology Referral Required

This patient requires immediate medical attention and should be referred to ophthalmology urgently (within 24 hours) or sent to an eye emergency department. The combination of eye pain, redness, tearing, retro-orbital discomfort, and foreign-body sensation represents a persistent ocular complaint that mandates specialist evaluation 1.

Why This Is Urgent

The 2024 AHA/Red Cross First Aid Guidelines explicitly state that a person who has persistent foreign-body sensation in the eye should seek immediate medical attention 1. While foreign-body sensation can result from benign causes like dust or eyelashes, it can also indicate serious conditions including:

• Embedded corneal foreign body
• Corneal abrasion
• Infectious keratitis (corneal infection)
• Anterior uveitis (intraocular inflammation)
• Scleritis
• Chemical injury or ultraviolet exposure

The deep retro-orbital pain is particularly concerning, as this suggests involvement beyond simple surface irritation 2.

Immediate Management Steps

What to Do NOW:

1. Do NOT allow the patient to rub her eye 1

   • Rubbing can worsen corneal injury or embed foreign bodies deeper

2. Protect the eye from further trauma

   • Tape a hard plastic eye shield, paper cup, or plastic cup over the affected eye to prevent unintentional touching 1

3. If she wears contact lenses:

   • Remove the contact lens immediately
   • Discontinue all contact lens use
   • This is a Class I recommendation 1

4. Arrange urgent ophthalmology evaluation

   • Same-day or next-day appointment
   • If unavailable, direct to eye emergency department

What NOT to Do:

• Do NOT attempt irrigation unless there is clear history of low-energy mechanism (wind-blown dust/dirt) 1
• Do NOT prescribe topical antibiotics without specialist evaluation
• Do NOT assume this is simple conjunctivitis—the retro-orbital pain and foreign-body sensation indicate potential deeper pathology

Red Flags Present in This Case

This patient has multiple concerning features 2:

• Pain behind the eyeball (retro-orbital pain) - suggests deeper involvement
• Persistent symptoms - not self-limited
• Foreign-body sensation - may indicate corneal pathology
• Redness and tearing - inflammatory response

What the Ophthalmologist Will Evaluate

The specialist will perform 3:

• Visual acuity testing - to establish baseline and detect vision compromise
• Slit-lamp biomicroscopy - to examine:
  • Corneal epithelium for defects, foreign bodies, or infiltrates
  • Anterior chamber for inflammation (cells and flare)
  • Conjunctiva and sclera for inflammation patterns
• Fluorescein staining - to identify corneal abrasions or ulcers
• Intraocular pressure measurement - to rule out acute glaucoma
• Pupillary examination - to assess for uveitis or other intraocular pathology

Potential Serious Diagnoses to Rule Out

The ophthalmologist must exclude 3, 2:

1. Bacterial keratitis - corneal infection requiring urgent antimicrobial therapy
2. Anterior uveitis - intraocular inflammation requiring topical steroids
3. Embedded corneal foreign body - requires removal by specialist
4. Corneal ulceration - risk of perforation and vision loss
5. Scleritis - severe inflammation requiring systemic treatment
6. Acute angle-closure glaucoma - though less likely given presentation

Common Pitfall to Avoid

Do not dismiss this as "simple conjunctivitis" or "dry eye." The presence of retro-orbital pain and foreign-body sensation distinguishes this from benign viral or allergic conjunctivitis 2. Conjunctivitis typically presents with discharge and grittiness but NOT deep orbital pain.

Pain Management While Awaiting Specialist

If there is a delay in ophthalmology evaluation, it is reasonable to offer:

• Oral acetaminophen or NSAIDs for symptomatic relief 1
• Do NOT use topical anesthetics outside of examination settings
• Do NOT prescribe topical steroids before ruling out infection

Documentation

Document clearly:

• Onset and duration of symptoms
• Any trauma history (even minor)
• Contact lens use details
• Current medications
• Any vision changes
• Exact nature and location of pain

The key principle: persistent eye symptoms with pain require specialist evaluation to prevent vision-threatening complications.
