Abstract:

Congenital dacryocystocele is formed when the nasolacrimal duct is obstructed at both the proximal and terminal ends, i.e. at the valve of Rosenmuller and the valve of Hasner, which results in the secondary dilatation of lacrimal sac. The main clinical manifestation is a bluish mass at lacrimal sac area. It is different from the common congentital dacryocystitis during childhood. There is self-healing tendency and effectiveness of conservative treatment for congenital dacyocystocele, but it is subject to the complication of the serious infection and life-threatening respiratory distress. Recent research is inclined to conservative treatment initially, then surgery  if conservative treatment failed.(Int Rev Ophthalmol,  2017,  41:    140-144)
