Abstract: Primary nasolacrimal duct obstruction typically presents as persistent tearing,which can lead to seconda-ry conditions such as keratitis,acute or chronic dacryocystitis,affecting ocular health.Nasolacrimal duct stenting is often an important adjunctive method for treating this condition,effectively reducing the postoperative membrane-related recur-rence rates of lacrimal duct probing,laser dacryoplasty,and lacrimal sac-nasal duct anastomosis.However,issues such as mechanical damage,persistent chronic inflammation post-surgery,and scar tissue formation still contribute to postopera-tive nasal lacrimal duct narrowing and re-obstruction.The article provides a comprehensive review of the pathogenesis of recurrent obstruction in nasolacrimal duct stenting and the corresponding advanced measures for improvement,offering new perspectives for clinical diagnosis and treatment.
