Day
Detailed medical condition and purpose of consultation: Lacrimal duct obstruction
Current general condition: Right eye discharge of thick mucus
First follow-up question: Pre-treatment care methods
Doctor's answer:
Hello: Due to the stenosis or obstruction of the nasolacrimal duct, tears are retained in the lacrimal sac, accompanied by bacterial infection. Symptoms include tearing and the discharge of mucous or purulent secretions from the lacrimal puncta when pressing the lacrimal sac area. The treatment using retrograde placement of a ball-tipped silicone tube for the nasolacrimal duct has shown satisfactory long-term efficacy. In newborns with nasolacrimal duct obstruction, the lacrimal sac is prone to recurrent dacryocystitis. Treatment should first focus on controlling the infection, followed by massage or surgical treatment for congenital nasolacrimal duct obstruction. In principle, conservative treatment with massage is adopted within the first six months, while more aggressive surgical therapy is employed after six months.
