Nozomi Matsumura


To evaluate the efficacy of endoscopic lacrimal duct recanalization (ELDR) for paediatric secondary acquired nasolacrimal duct obstruction (SANDO) after epidemic keratoconjunctivitis (EKC).


The subjects were 27 consecutive patients with a clinical diagnosis of SANDO after EKC who underwent ELDR under general anesthesia at Kanagawa Children’s Medical Center from 2012 to 2023. Patient background, surgical records, stenting duration, and outcome six months after surgery were investigated. The obstruction was diagnosed in all patients using both dacryocystography and dacryoendoscopy.


Patient background: 14 boys, all unilateral (20 right, 7 left), mean age at onset of EKC was 23 ± 24 months, and at surgery was 59 ± 42 months. Surgical records: 24 cases (89%) had partial obstruction, of which 19 had one blockage, and 5 had two blockages. The blockage sites were as follows: the sac-duct junction in 15 cases, the common canaliculus (CC) in 11 cases, and one case each for the canaliculi, punctum, and lower end of the duct. Generalized NLDO (including 1 case with CC obstruction) was seen in 3 cases (11%). In all cases, a self-retaining bi-canalicular stent was inserted using a dacryoendoscopy. The mean duration of stent placement was 64 ± 27 days. Outcomes were 25 successful (93%), 2 improved (7%), and 0 unchanged. No recurrence has been observed.


ELDR with intubation for paediatric SANDO after EKC had a good outcome.
