Treatment

  • Copious prolonged irrigation of the eyes with sterile normal saline or, if not immediately available, tap water
  • Irrigate for 30 minutes (with intermittent topical anaesthetic if required) or until pH between 7 and 8
    • To measure, cease irrigation, wait for 1 minute, apply universal indicator paper to fornix
    • When pH normal stop irrigation and re-check after additional 30 minutes
  • Remove any particulate matter
  • Give ocular lubricants for symptomatic relief
    • Manage as abrasion if epithelial loss
      • Ask if allergic to Chloramphenicol
      • If not, supply Chloramphenicol 1% eye ointment 3 times daily for 5 days
