What is a nasolacrimal duct?
The nasolacrimal duct is a tubular structure that drains tears from the eye's surface into the nasal cavity. It begins at the lacrimal sac, located at the inner corner of the eye, and extends down to open into the inferior meatus of the nasal cavity. This duct helps maintain tear drainage and prevents overflow, which can lead to tears spilling onto the face. Dysfunction or blockage of the nasolacrimal duct can result in conditions such as epiphora, where tears accumulate excessively.
