[Chinese expert consensus on diagnosis and treatment of congenital nasolacrimal duct obstruction (2021)].

Congenital nasolacrimal duct obstruction is a common ophthalmic disease in children with a high incidence. The main clinical manifestation is persistent epiphora soon after birth, sometimes accompanied by an abscess. At present, the treatment methods used include conservative treatment and surgical treatment, but there exist some problems, such as improper surgical indications and non-standard surgical operation. In view of this, the Oculoplastic and Orbital Disease Group of Chinese Ophthalmological Society of Chinese Medical Association has reached a consensus after full discussion, in order to standardize the clinical diagnosis and treatment of congenital nasolacrimal duct obstruction in China. (Chin J Ophthalmol, 2021, 57: 814-818).
