(Blocked Tear Duct; Nasolacrimal Duct Obstruction; Lacrimal Duct Obstruction; Dacryostenosis)

Causes

In some babies, problems in normal development can cause lacrimal duct obstruction. A thin membrane may cover the opening of the duct into the nose.

Risk Factors

Factors that may increase your baby’s chance of lacrimal duct stenosis:

Symptoms

Lacrimal duct stenosis may cause:
  • Excessive tearing
  • Recurrent red eye or eye irritation
  • Tear duct infection ( dacryocystitis ) causing redness, warmth, swelling around the eye, and discharge with pus
  • Cloudy or mucous-like discharge from the tear duct
  • Crusting on the eyelid
  • Bloody tears

Diagnosis

The doctor will ask about your baby’s symptoms and medical history. The doctor will do an exam. Your baby may need to see a doctor who specializes in eye conditions in children.The eye doctor may do a dye disappearance test. This test will help to confirm that there is a blockage in the tear duct.

Treatment

Talk with the doctor about the best treatment plan for your baby. In infants, this condition often heals by itself in the first year of life.Treatment options include:
  • Massage—The doctor may gently push on the area where the tear duct runs out of the eye, between the baby’s eye and nose. This helps to push tears through the duct. You will also do this at home 3 times a day until the tear duct has opened.
  • Probing—The doctor may pass a tiny probe into the duct to open it up. In some cases, the ducts may be dilated with a balloon or stented to keep them open.
  • Surgery—In some cases, surgery may be needed to open up the duct. In one type of surgery, the doctor puts a tiny, flexible instrument into the tear duct to see what is causing the blockage. The doctor may then flush fluid through the instrument. A laser may be used to cut away the blockage.
