Dacryoendoscopic findings of lacrimal passage with congenital punctal atresia.Orbit. 2013 Oct; 32(5):338-40.O
A 43-year-old woman presented with epiphora caused by upper and lower congenital punctual atresia with papilla. She underwent 2-snip punctoplasty and intubation under local anaesthesia. During the surgery, a dacryoendoscopic examination was performed. After performing the punctoplasty, the lacrimal passage was confirmed to have complete canalisation to the nasal cavity. Both upper and lower canaliculi appeared to be narrower and had difficult expansion compared with canaliculi in congenital nasolacrimal duct obstruction or primary acquired nasolacrimal duct obstruction without canalicular stenosis. The lacrimal sac and the nasolacrimal duct also showed complete canalization with normal colour.
