What is the appropriate management for a 60-year-old woman with a white vinegar splash to the eye?

Immediate Management of White Vinegar Eye Splash

Immediately irrigate the eye with copious amounts of tap water or normal saline for at least 15-30 minutes, starting at the scene of injury before any other intervention. 1, 2

Initial Emergency Treatment

The priority is rapid and thorough decontamination:

• Begin irrigation immediately - do not delay for any reason, including waiting for specialized solutions 3
• Use tap water (readily available, safe, and effective) or lactated Ringer's solution if in hospital 1, 2
• Continue irrigation for minimum 15-30 minutes; in severe exposures up to 2 hours may be needed 2
• Remove contact lenses if present during irrigation

White vinegar (acetic acid ~5%) is an acid burn, which generally causes less severe injury than alkali burns, but still requires aggressive immediate irrigation. 1

After Initial Irrigation

Following decontamination, perform these steps:

1. Measure ocular pH - this is critical and pH testing equipment should be available in emergency departments 4

   • Continue irrigation until pH normalizes (7.0-7.4)
   • Recheck pH 10-15 minutes after stopping irrigation to ensure no residual chemical

2. Assess severity through clinical examination:

   • Visual acuity measurement
   • Slit-lamp examination if available
   • Evaluate extent of corneal and conjunctival involvement
   • Check for limbal ischemia

3. Immediate ophthalmology referral is recommended for all but the most trivial chemical burns 2

Medical Management Post-Irrigation

After stabilization with irrigation 5, 3:

• Topical antibiotics to prevent secondary infection
• Agents that promote epithelialization
• Anti-inflammatory therapy as indicated by severity
• Pain management
• Cycloplegics if significant anterior chamber inflammation

Critical Pitfalls to Avoid

• Do not delay irrigation to search for specialized solutions - tap water immediately is superior to delayed "better" solutions 1
• Do not neutralize acid with alkali or vice versa - this generates heat and worsens injury
• Do not assume mild initial appearance means mild injury - reassess after irrigation and monitor pH

The evidence consistently shows that immediate on-scene irrigation with tap water following chemical burns results in significantly better clinical and ocular outcomes compared to delayed treatment. 1
