Lacrimal Duct Stenosis
Lacrimal Duct Stenosis
(Blocked Tear Duct; Nasolacrimal Duct Obstruction; Lacrimal Duct Obstruction; Dacryostenosis)
- Premature birth
- Abnormal development of the face or skull
- 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
- 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.
