There have been very few reports of all four punctal agenesis in children presenting with congenital nasolacrimal duct obstruction in the literature, and even fewer with associated lacrimal sac and nasolacrimal duct (NLD) abnormalities.[1],[2]

An 11-year-old boy presented with a large medial canthal swelling on the left side of two years duration [Figure 1]a. He also complained of bilateral epiphora, and upon examination, there were signs of punctal agenesis on both sides [Figure 1]b. On computed tomography, the right NLD seemed normal, but the left NLD exhibited proximal dilatation and a bony obstruction at the bottom that separated it from the inferior meatus [Figure 1]c. The right NLD was normal and patent on nasal endoscopy, but the left NLD opening was missing in the inferior meatus [Figure 1]d, a finding consistent with computed tomography (CT) results. Lacrimal sac mucocele was caused by a blocked NLD on the left.

The lacrimal sac was observed to be dilated with thin, translucent walls during endoscopic osteotomy [[Figure 2]a, red star]. The lacrimal sac was marsupialized, revealing mucoid fluid and weak membranous sac flaps that made attaining a satisfactory lacrimal sac mucosa to nasal mucosa approximation difficult [[Figure 2]b, star]. The nasolacrimal duct was found to be grossly dilated [[Figure 2]c pointer]. Histopathology revealed an irregular lumen lined by thinned out pseudostratified columnar epithelium with goblet cells [Figure 2]d.
Figure 2: (a) A left endoscopic dacryocystorhinostomy (DCR) was done to reveal a very thin and transparent maldeveloped lacrimal sac (red star). Middle turbinate is visible medial to it (black star); (b) As the lacrimal sac is dissected, mucoid fluid drains and a clear lumen is visible (red star). The common canalicular opening is absent, and membranous sac walls have given way. Flaps cannot be formed since there are no well-defined sac walls; (c) A close endoscopic image of sac lumen reveals sac duct junction (white arrow) and a dilated NLD (pointer); (d) A microphotograph shows columnar epithelium and goblet cells

The membranous lacrimal sac flaps indicate that the lacrimal sac has not fully formed. Thus, in cases of proximal lacrimal agenesis, distal lacrimal dysgenesis may be present, affecting surgical planning.
