What is inflammation of the lacrimal duct called?

Inflammation of the lacrimal duct is called dacryocystitis. This condition typically occurs due to an infection or blockage of the nasolacrimal duct, leading to swelling, pain, and sometimes discharge from the affected eye. It is most commonly seen in infants but can also occur in adults, particularly those with other underlying conditions. Treatment may involve antibiotics or surgical intervention to relieve the blockage.
