Treatment of Corneal Abrasion in Non-Contact Lens Wearers

Antibiotic Selection and Rationale

The American Academy of Ophthalmology recommends using either Polytrim (polymyxin B-trimethoprim) or erythromycin ointment as prophylactic antibiotic therapy for non-contact lens wearing patients with corneal abrasion, with Polytrim drops preferred during the day and erythromycin ointment reserved for bedtime use, due to its broad-spectrum coverage against both gram-positive and gram-negative organisms 1, 2
Topical antibiotic drops are the preferred method because they achieve higher corneal tissue levels compared to ointments, making them more effective for prophylaxis in traumatic corneal abrasions 3

The American Academy of Ophthalmology does not recommend eye patching for non-contact lens wearing patients with corneal abrasion, as it does not improve pain and may delay healing, and instead suggests standard broad-spectrum prophylaxis 1, 2
Antipseudomonal coverage is not required for non-contact lens-related abrasions, and standard broad-spectrum prophylaxis is sufficient 1, 2

The American Academy of Ophthalmology recommends prescribing oral acetaminophen or NSAIDs for pain control in non-contact lens wearing patients with corneal abrasion, and cycloplegics are not routinely needed for uncomplicated abrasions unless substantial anterior chamber inflammation is present 4

Increasing pain, purulent discharge, or corneal infiltrate suggesting infection, vision loss or irregular pupil, are red flags that require immediate referral to an ophthalmologist 4

The American Academy of Ophthalmology recommends avoiding chronic or prolonged antibiotic use, as it may promote resistant organisms, and a 5-7 day course is typically sufficient for prophylaxis 2, 3
A Cochrane review found very low certainty evidence regarding antibiotic prophylaxis effectiveness, but clinical guidelines still recommend it based on the low risk of treatment and potential severity of untreated infection 1, 2
