Review of the diagnosis and management of acquired nasolacrimal duct obstruction.
BACKGROUND
Acquired nasolacrimal duct obstruction is a common cause of epiphora. The absolute or partial blockage of the nasolacrimal duct occurs most frequently in middle-aged and elderly women. In addition to the troublesome symptom of epiphora, acquired nasolacrimal duct obstruction is predominantly the underlying cause of both acute and chronic dacryocystitis.


METHODS
The primary eye care provider plays an essential role in the diagnosis and management of the patient with epiphora. The potentially serious ramifications of acquired nasolacrimal duct obstruction demand a thorough understanding of the clinical presentation of this disorder. In addition, it is essential the optometrist be well-acquainted with the surgical treatments often necessary for optimal management.


CONCLUSIONS
Whether treatment is provided or an appropriate referral is made, the optometrist is instrumental in providing care for the patient who experiences an acquired nasolacrimal duct obstruction.
