Infected corneal abrasion — Clinical Guidelines

Overview

Infected corneal abrasions occur when a corneal scratch becomes colonized by microorganisms, potentially leading to complications such as recurrent erosion syndrome and suppurative keratitis. Proper management is crucial to prevent these complications and ensure healing 1 2 6.

Diagnosis

Clinical Presentation: Pain, redness, photophobia, and tearing 1.

Diagnostic Tests: Slit-lamp examination to visualize the abrasion; fluorescein staining to confirm the extent 1.

Infection Signs: Presence of purulent discharge, increased pain, and delayed healing may indicate infection 2 6.

Management

Antibiotic Therapy: For suspected or confirmed infection, use topical antibiotics effective against Pseudomonas, such as fortified antibiotics or fluoroquinolones 6.

Pain Management: Ophthalmic nonsteroidal anti-inflammatory drugs (NSAIDs) provide significant pain relief without delaying healing 3.

Avoid Patching: Generally not recommended for simple abrasions to prevent bacterial growth; exceptions for very large abrasions 5.

Follow-Up: Ensure close monitoring, especially in nonophthalmologist settings, with 24-hour follow-up recommended 6.

Special Populations

Contact Lens Wearers: Higher risk of Pseudomonas infection; avoid occlusive patching and steroid use 6.

No Specific Guidance: Limited evidence addressing management differences in pregnancy, pediatrics, or elderly patients based on provided abstracts 1 2 3 5 6.

Key Recommendations

Use Topical Antibiotics for suspected or confirmed infection, particularly those covering Pseudomonas, to prevent progression to suppurative keratitis (Evidence: Strong 6).

Administer Ophthalmic NSAIDs for pain relief in corneal abrasions without delaying healing (Evidence: Moderate 3).

Avoid Occlusive Patching in routine management to minimize infection risk, except in very large abrasions where patching may aid healing (Evidence: Expert opinion 5).
