Endoluminal lacrimal duct recanalization for pediatric lacrimal duct obstruction: etiologic spectrum and surgical outcomes.
Article in Japanese journal of ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo clarify the clinical characteristics and etiologic diversity of pediatric lacrimal duct obstruction in children aged ≥1 year requiring surgical treatment under general anesthesia and to evaluate the outcomes of endoluminal lacrimal duct recanalization (ELDR). STUDY
designRetrospective observational study.
methodsAll pediatric lacrimal surgical procedures performed under general anesthesia at our institution between 2011 and July 2025 were reviewed. All cases underwent dacryoendoscopic evaluation and treatment. Clinical characteristics, etiologies, and surgical outcomes were analyzed.
resultsThe study included 245 patients (338 eyes). Thirty-four eyes (10.1%) had a history of failed probing. Congenital obstruction accounted for 259 eyes (76.6%), acquired obstruction for 38 eyes (11.2%), and syndromic cases for 41 eyes (12.1%). Approximately one-third of all eyes had simple congenital nasolacrimal duct obstruction (CNLDO) caused by membranous distal obstruction. Post-epidemic keratoconjunctivitis obstruction accounted for approximately 10% of cases, for which favorable outcomes were demonstrated following ELDR with intubation. In nonsyndromic cases (congenital and acquired), the success rate, defined as complete resolution, was 97.6% (290/297 eyes). In contrast, syndromic cases demonstrated a significantly lower success rate of 56.1% (23/41 eyes; P < 0.001). No major complications were observed.
conclusionsThe obstruction of the lacrimal duct in pediatric patients requiring surgery under general anesthesia includes a broad spectrum of pathologies beyond simple CNLDO. In patients without congenital malformation syndromes, ELDR was associated with a high success rate and appears to be a safe and effective treatment option for pediatric lacrimal duct obstruction.
