Utility of intraocular endoscope for lacrimal canaliculi and sac examination.
Article in International ophthalmology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeIntraocular endoscope was used as a dacryoendoscope, and its observations and performance in lacrimal drainage system (LDS) are reported.
methodsThe Endo Optiks (Little Silver, New Jersey, USA), an intraocular endoscope (modified with customized sheath), was used for LDS visualization in ten normal adults and five patients with lacrimal disorders.
resultsWe were able to capture high-definition images of lacrimal canaliculi and sac in all normal adults. Smooth whitish canalicular mucosa with lumen could be appreciated in all normal individuals. Common canaliculus showed variable folds among individuals and reddish lacrimal sac mucosa could be appreciated with great details. In patients with canalicular obstruction, site of obstruction was presented as whitish gray area with no visible lumen, which could be opened up precisely with trephination. No false passage was formed in any of the cases. One of the cases had membranous canalicular obstruction, which was opened with probe itself. Nasolacrimal duct could not be examined due to the shorter length of the probe.
conclusionIntraocular endoscope can be used as high-resolution dacryoendoscope for visualization of lacrimal canaliculi and sac.
