What is the recommended approach for treating debris in the eyes?

Approach to Debris in Eyes

Immediately irrigate the eye with copious amounts of clean tap water or saline for at least 15 minutes to remove debris and prevent corneal damage, followed by gentle mechanical removal of any remaining debris by an ophthalmologist or trained specialist. 1, 2

Immediate Initial Management

First-Line Irrigation

• Begin irrigation immediately at the scene with large volumes of clean tap water—this is the most critical step to minimize tissue damage and remove loose debris 1, 2
• Continue irrigation for a minimum of 15 minutes, using continuous flow rather than intermittent splashing 1, 3, 4
• If immediately available, normal saline, Ringer's lactate solution, or commercial eye wash solutions are reasonable alternatives to tap water 1, 2
• Do not delay irrigation to search for "better" solutions—every second counts, and tap water is safe, effective, and readily available 2, 4

Critical Technique Points

• Direct the irrigation flow away from the unaffected eye to avoid cross-contamination 2
• Some patients may require assistance keeping their eyelids open during irrigation 3, 2
• Use a continuous stream delivery system (such as IV tubing with a 16-gauge catheter) for optimal irrigation if available 5

Specialized Debris Removal

Daily Ocular Hygiene Protocol

• Maintain daily ocular hygiene with gentle saline irrigation to remove mucous or debris from the ocular surface—this should be performed by an ophthalmologist or specialist ophthalmology nurse 6
• This procedure must include direct visualization and assessment of the ocular surface integrity 6

Mechanical Debris Removal

• Mechanical removal of pseudomembranes and debris should be performed daily during the acute phase using saline irrigation, a squint hook, and forceps under direct visualization 6
• Apply topical local anesthetic (proparacaine or tetracaine) prior to the procedure 6
• Scissors may be needed when adhesions are well developed and cannot be removed with forceps alone 6
• Avoid blind sweeping of the fornices with cotton buds or glass rods—this can cause additional corneal damage 6

Assessment with Fluorescein Staining

• Use topical fluorescein eye drops to assess the extent of epithelial loss on both the cornea and conjunctiva 6
• This helps identify areas of corneal damage that may require additional treatment 6

Supportive Care After Debris Removal

Lubrication

• Apply nonpreserved lubricant eye drops (hyaluronate or carmellose) every 2 hours to maintain corneal epithelial integrity 6, 2
• Continue lubrication throughout the acute phase and adjust frequency based on symptoms 6

Infection Prophylaxis

• Initiate broad-spectrum topical antibiotic prophylaxis (such as moxifloxacin or levofloxacin four times daily) if corneal fluorescein staining or frank ulceration is present 6, 2
• Choice of antibiotic should be guided by local antimicrobial resistance patterns 6

Anti-inflammatory Treatment

• Consider topical corticosteroid drops (dexamethasone 0.1%) under ophthalmologist supervision to reduce ocular surface damage 6, 2
• Use corticosteroids with caution as they can mask signs of corneal infection and should not be used in the presence of corneal epithelial defects 6, 2

Follow-Up and Monitoring

Ophthalmology Consultation

• Arrange urgent ophthalmology review for initial examination to assess the extent of eyelid, conjunctival, and corneal involvement 6
• Daily ophthalmology review is necessary during the acute phase for moderate to severe exposures 6, 2

Prevention of Corneal Exposure

• In unconscious patients or those with lagophthalmos, establish a moisture chamber with polyethylene film and long-lasting ophthalmic ointment to prevent corneal exposure and ulceration 6

Common Pitfalls to Avoid

• Never delay irrigation to transport the patient or search for specialized solutions—immediate decontamination with whatever water is available is critical 2
• Avoid contaminating the unaffected eye during irrigation, which can convert a unilateral injury to bilateral 2
• Do not perform blind mechanical sweeping of the fornices, which may cause additional corneal damage 6
• Do not use topical corticosteroids without ophthalmology supervision, especially in the presence of corneal epithelial defects 6, 2
