• Inflammation of cornea caused by infection, trauma, dry eyes, ultraviolet exposure, contact lens overwear, or degeneration
  • Undertreated keratitis often leads to scarring or perforation with loss of sight
  • Corneal trauma
  • Contact lens overwear
  • Refer emergently to ophthalmologist
  • Herpes simplex keratitis treated with oral anti-viral medications (acyclovir, valacyclovir, famciclovir)
  • Other causes require varying types of treatment
  • If treatment fails to prevent persistent inflammation of subsurface layers, scarring will permanently damage sight
  • Corneal perforation can lead to endophthalmitis and eventual need to remove eye ("enucleation")
