Corneal Abrasion Treatment Guidelines

First-Line Treatment

The American Academy of Ophthalmology recommends that all patients with corneal abrasions should receive topical broad-spectrum antibiotic drops started within 24 hours of injury to prevent bacterial keratitis and ulceration 1, 2
Fluoroquinolones are the preferred first-line agents because they achieve high corneal tissue levels and provide broad-spectrum coverage against both gram-positive and gram-negative organisms 1, 3
For simple, non-contact lens related abrasions, moxifloxacin 0.5% or gatifloxacin 0.5% should be applied four times daily until complete epithelial healing is confirmed 1, 2, 3
For contact lens-related abrasions, mandatory antipseudomonal coverage with fluoroquinolones (moxifloxacin 0.5% or gatifloxacin 0.5%) is required due to dramatically increased risk of Pseudomonas keratitis 1, 2, 3
More aggressive treatment with frequent antibiotic drops is recommended for contact lens-related abrasions 1
Never patch the eye in contact lens wearers as this increases bacterial keratitis risk 1, 2, 3
Advise complete avoidance of contact lens wear until healing is confirmed by examination 1, 3

Over-the-counter oral acetaminophen or NSAIDs are reasonable for treating residual discomfort 1, 2, 3

Do not patch the eye - patching does not improve pain, may delay healing, and increases infection risk, especially in contact lens wearers 1, 2, 3
Avoid topical corticosteroids initially as they delay healing and increase infection risk 1, 3
Do NOT use combination steroid-antibiotic drops as initial therapy 2, 3
Steroids should only be added after 2-3 days of antibiotic-only therapy if bacterial infection is controlled 2, 3
Never use corticosteroids in suspected Acanthamoeba, Nocardia, or fungal infections as they worsen outcomes 2, 3

Prophylactic antibiotics are most effective when started within 24 hours of the abrasion - treatment prevents ulceration specifically when initiated in this timeframe 1, 2, 3, 4

All other patients require re-evaluation within 24 hours to assess healing and detect early infection 1, 2, 3
Regular follow-up is necessary to monitor healing and detect early signs of infection 1, 2

Central infiltrate >2mm 2
Significant stromal involvement or corneal melting 2
Corneal infiltrate with suppuration, necrosis, or feathery margins suggesting bacterial keratitis 2
High-velocity eye injuries or penetrating trauma 1, 2
Irregular pupil after trauma 2
Eye bleeding or loss of vision after trauma 2
Increasing pain, purulent discharge, or vision changes 1, 2, 3

Chronic prophylactic antibiotic use promotes resistant organisms and should only be used for finite treatment periods during the healing phase 1, 2, 3
Increasing resistance of MRSA and Pseudomonas to fluoroquinolones has been documented 2
Patient education is essential - instruct patients on infection warning signs (increasing pain, discharge, vision changes) and the need for prompt ophthalmologic care if these develop 1, 2, 3
Inadequate blinking or incomplete eyelid closure during sleep significantly impairs healing 1, 2

If the abrasion progresses to bacterial keratitis, initiate loading dose every 5-15 minutes, then hourly dosing 2
Consider fortified antibiotics (tobramycin 1.5% + cefazolin 10%) for severe cases 2
Fourth-generation fluoroquinolones (moxifloxacin, gatifloxacin) have demonstrated at least equivalent efficacy to fortified combination therapy 2
Obtain cultures before antibiotic initiation 2
