Corneal Erosion

Change Language German

Causes

  • usually after trauma (injury with fingernail, object)
  • can also occur spontaneously, e.g. in map-dot fingerprint, recurrent erosions after previous trauma

Findings

  • Epithelial defect, stains with fluorescein, no infiltrate
  • Trauma: laceration/perforation? Anterior chamber cells?
  • Evert the upper lid to rule out any subtarsal foreign body

Management

  • Consider prophylactic antibiotic treatment
    • e.g. Tobrex gtt (Tobramycin) 4x daily or Floxal gtt (Ofloxacin) 4x daily (alternatively ointment)
    • in case of injury with organic material (branch, plant, fingernail etc.): Floxal gtt 4x daily
    • consider additional lubrication (drops, vitamin A ointment at night)
    • consider cycloplegic drops (e.g. Scopolamine 0.25% 1-3x daily)
    • in case of large erosions: consider Floxal ointment and bandage or bandage contact lens + Floxal gtt 3x/d
    • in case of loose epithelium: debridement with a hockey knife

Follow-up

  • Depending on findings:
    • small epithelial defects: further appointments may not be needed
    • large epithelial defects: the next day: re-epithelialisation tendency? Then until epithelial closure
  • Contact lens wearers should wait at least 7-10 days after epithelial closure to insert a new contact lens
