Blocked Tear Ducts
Nasolacrimal Duct Obstruction
📋Overview
Blocked tear ducts, medically referred to as nasolacrimal duct obstruction, occur when the tear drainage system is partially or completely blocked. This leads to impaired tear drainage from the eye into the nasal cavity, causing excessive tearing and potential eye irritation. The term 'blocked tear ducts' is commonly used in lay language, while nasolacrimal duct obstruction is the preferred clinical term.
