Emergency Room Treatment for Bleach Splashed in Eyes
Immediately irrigate the affected eye(s) with copious amounts of tap water for at least 15 minutes or until advanced medical care arrives, then urgently refer to ophthalmology for evaluation and continued management. 1
Immediate First Aid Management
The cornerstone of treatment is rapid and continuous irrigation:
- Begin irrigation immediately with copious tap water for at least 15 minutes 1
- Use a continuous stream from a 1-liter bag of normal saline attached to IV tubing with a 16-gauge Teflon catheter if available in the ED 2
- If tap water is unavailable, normal saline or commercial eye irrigation solutions are reasonable alternatives 1
- Irrigate the entire ocular surface and fornices thoroughly 2
- Continue irrigation until ophthalmology evaluation occurs 1
Critical Pitfall
The 2015 ILCOR systematic review found that tap water is actually superior to normal saline for alkali injuries (bleach is alkaline with pH ~12-13). Animal studies showed significantly lower maximum pH levels when using tap water versus saline for irrigation 3. This challenges traditional teaching that only sterile saline should be used.
Emergency Department Assessment
After initial irrigation:
- Contact poison control center (1-800-222-1222 in US) for guidance 1, 4
- Measure ocular pH - this is essential and should be available in all EDs 5
- Continue irrigation until pH normalizes (target pH 7.0-7.4)
- Assess for:
- Visual acuity changes
- Corneal epithelial defects (fluorescein staining)
- Extent of conjunctival involvement
- Limbal ischemia (indicates severe injury)
Ophthalmology Referral
All bleach exposures require ophthalmology consultation 1, 4:
Immediate consultation (same day) for:
- Any epithelial defect
- Decreased vision
- Persistent symptoms after irrigation
- Corneal opacity or limbal blanching
Chemical eye injuries can cause severe, sight-threatening damage requiring specialist assessment even when initial symptoms seem mild 6, 5
Post-Irrigation Management (Pending Ophthalmology)
While awaiting specialist evaluation:
- Apply preservative-free ocular lubricants (hyaluronate or carmellose drops) every 2 hours 7
- Consider topical broad-spectrum antibiotic prophylaxis if corneal epithelial defect present 7
- Do not patch the eye - this can worsen outcomes
- Oral acetaminophen or NSAIDs for pain control 8
What NOT to Do
- Do not delay irrigation to search for specific solutions - tap water is immediately available and effective 1
- Do not attempt to neutralize with acids or other chemicals 9
- Do not administer anything by mouth unless directed by poison control 9
- Do not allow patient to rub the affected eye 8
Evidence Strength
The recommendation for immediate copious irrigation is based on Class I evidence from the 2015 American Heart Association/American Red Cross First Aid Guidelines 1 and the 2015 ILCOR systematic review 3. While the animal evidence is limited, the extreme caustic nature of alkali injuries (bleach has pH 12-13) and the time-dependent progression of tissue damage make immediate irrigation the unequivocal standard of care 10, 11.
Household bleach (typically 5.25% sodium hypochlorite) can cause corneal injuries ranging from mild superficial epithelial disturbance to severe corrosive damage depending on concentration and duration of exposure 10, 2. The severity cannot be reliably predicted from history alone, necessitating ophthalmology evaluation in all cases 6, 4.
