When tear ducts are blocked, trapped bacteria in the nasolacrimal sac can lead to infection (called dacryocystitis). Symptoms of infection include:

  • Inflammation (swelling), tenderness and redness of the inside corner of the eye or around the eye and nose
  • Recurrent eye infections
  • Eye mucus discharge
  • Crusty eyelashes
  • Blurred vision
  • Blood-tinged tears
  • Fever
