How long do gunky eyes/clogged tear ducts last on an infant? mine is 7 weeks.

Blocked tear duct: Blocked tear ducts can persis for many months. I normally recommend controlling the mild secondary infection with intermittant antibiotic eye drops until 4-6 months of age. I refer the small # who persist beyond that time to a pediatric ophthalmologist for probing of the ducts.

Variable: There is a drainage tubing from the eyelids into the nose (you have to blow your nose after crying as a demonstration of this). About 1-2% of infants have incomplete opening of the lower portion of this system. Over 75% of these will open by 6 months of life but the others may require a probe to open it. Start with your pediatrician to help with this but an ophthalmologist may be consulted.
