Management of Ocular Foreign Body and Corneal Abrasion

Immediate Assessment and Red Flags

The American College of Emergency Physicians recommends testing visual acuity immediately to establish baseline function and identify any acute vision loss requiring urgent ophthalmology referral 1
High-velocity mechanisms, such as grinding or metal work, are associated with a higher risk of globe penetration 1
An irregular pupil after trauma indicates a penetrating injury, according to the American Academy of Ophthalmology 2, 1
Eye bleeding or vision loss after trauma requires emergency ophthalmology referral, as recommended by the American Academy of Ophthalmology 2
Moderate-to-severe pain and photophobia are red flags for ocular foreign body and corneal abrasion, as stated by the British Journal of Dermatology 3
Visible corneal damage, such as uptake of fluorescein, ulceration, haze, opacity, or purulent discharge, is a critical red flag, according to the British Journal of Dermatology 3
Contact lens-related injuries require immediate removal and discontinuation, as recommended by the American Academy of Ophthalmology 2

The American Academy of Ophthalmology recommends irrigating with sterile saline to flush loose material first 1
Allowing natural tears to wash out the object or using tap water/commercial eye wash is a recommended initial management step, according to the American Academy of Ophthalmology 2
Shielding the eye with a hard plastic eye shield, paper cup, or plastic cup is essential to prevent unintentional touching, as stated by the American Academy of Ophthalmology 2

Broad-spectrum topical antibiotic prophylaxis, such as moxifloxacin four times daily or gatifloxacin, is recommended after foreign body removal, according to the American Academy of Ophthalmology 1
Topical NSAID, such as ketorolac, is used for pain, photophobia, and foreign body sensation, as recommended by the American Academy of Ophthalmology 1
Cycloplegic agent, such as cyclopentolate, is used to reduce ciliary spasm pain, according to the American Academy of Ophthalmology 1
Oral acetaminophen or NSAIDs are recommended for additional pain relief, as stated by the American Academy of Ophthalmology 2, 1

Visual acuity, mechanism of injury, and presence of fluorescein uptake should be reported to ophthalmology, according to the American Academy of Ophthalmology 1, 3
Presence of rust ring, any red flag features, and corneal sensitivity status should also be reported, as recommended by the American Academy of Ophthalmology 1, 3, 2

Close follow-up within 24-48 hours is mandatory to assess for corneal infection development, according to the American Academy of Ophthalmology 1
Worsening pain or vision, increasing redness, discharge or purulent material, and persistent foreign body sensation despite treatment are warning signs to return immediately, as stated by the British Journal of Dermatology and the American Academy of Ophthalmology 3, 2

All patients require ophthalmology follow-up within 24-48 hours after foreign body removal to monitor for infection, according to the American Academy of Ophthalmology 1
For metallic foreign bodies, assessment for rust ring formation and ensuring complete removal is crucial, as recommended by the American Academy of Ophthalmology 1

The American Academy of Ophthalmology recommends evaluating the corneal epithelium for defects, location of foreign body, depth, and presence of rust ring under slit-lamp biomicroscopy 4
Fluorescein staining is used to identify epithelial defects and differentiate from pooling in areas of thinning, as recommended by the American Academy of Ophthalmology 4
The American Academy of Ophthalmology suggests everting the eyelid to inspect tarsal conjunctiva for retained foreign bodies 4

Cultures are recommended for corneal foreign bodies with associated infiltrates, particularly for central, large infiltrate with significant stromal involvement or melting, as suggested by the American Academy of Ophthalmology 4
The American Academy of Ophthalmology recommends cultures for corneal foreign bodies with ≥1+ cells in anterior chamber 4
Multiple corneal infiltrates or atypical features require cultures, according to the American Academy of Ophthalmology 4
