A blocked tear duct occurs when a thin membrane covers the end of the tear duct or when a blockage occurs in the tear duct. Nasolacrimal duct obstruction occurs frequently. About a quarter of all infants are born with this condition. Blocked tear ducts can cause recurrent eye infections as well as tearing. Many times, the blockage will open spontaneously as the infant grows. Sometimes, a doctor may prescribe massage of the lacrimal sac to help open the tear duct. About 80% of blocked tear ducts resolve by 9 months of age, Despite time and massage, sometimes the blockage does not resolve itself.
If the blockage has not resolved by 9 months of age, the child should see a pediatric ophthalmologist for evaluation. After a complete eye exam, the doctor will decide if the child needs a tear duct probing and irrigation. A tear duct probing and irrigation is usually performed in the operating room under general anesthesia.
What Happens Before Surgery?
A few days before the surgery, a nurse from the same day surgery department will contact you. They will confirm the scheduled surgery time and tell you what time your child should arrive at the hospital on the day of surgery. Eating and drinking instructions are age-specific, and the nurse will review this information during the call.
Bring a list of all medicines your child is on as well as the physical exam form completed by their doctor. If a child takes medicines routinely, they can usually take the morning dose with a sip of water. Notify the doctor of any morning medications prior to surgery.
On the day of the procedure, have your child wear comfortable clothing. Remove any jewelry and fingernail polish before you leave home. A doctor or nurse practitioner from the anesthesia department will talk to you about the anesthesia. They will also answer any questions you may have.
