An unruptured mucosal fold (Hasner flap) at the lower end of the nasolacrimal duct blocking the nasolacrimal duct at birth is the main cause of congenital dacryocystitis in infants. The main symptoms of this disease are: tear overflow, discharge, and mucopurulent or purulent discharge on examination of the lacrimal sac.
For children under 2 months old, massage of the lacrimal sac area can be performed as prescribed by the doctor to reduce the symptoms and strive for self-healing. children over 2 months old should go to the hospital for lacrimal flushing, and children 4 months old who are still not cured need to undergo lacrimal duct exploration surgery. Our ophthalmology department handles tens of thousands of patients with various types of congenital lacrimal duct occlusion each year, with a cure rate of 99.9%. In the rare cases where lacrimal duct exploration is not curative, lacrimal duct implantation can be performed. Yani Mao, Ophthalmology Department, Guangzhou Women’s and Children’s Medical Center
