Viscocanalostomy combined with nearly 360-degree suture trabeculotomy for the treatment of primary congenital glaucoma: a preliminary report of a novel technique for trabeculotomy.
Article in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
purposeThe aim of this study was to determine the preliminary efficacy and safety of a novel technique for trabeculotomy for the treatment of primary congenital glaucoma (PCG).
methodsThis retrospective interventional study was conducted on patients with PCG. Pliability test was performed among 5/0 and 6/0 polypropylene sutures and the flexible illuminated microcatheter. Viscocanalostomy was first performed and the Schlemm's canal was identified. Then, suture trabeculotomy was completed except the region for viscocanalostomy. The preoperative and follow-up data were recorded and analyzed. Success criteria were defined as intraocular pressure (IOP) ≤ 21 mmHg without (complete success) or with medications (qualified success).
results5/0 polypropylene suture was an appropriate option for cannulation of Schlemm's canal. A total of 33 eyes from 23 consecutive patients were included with a mean follow-up of 9.3 ± 3.6 months (range 6-18 months). Circumferential cannulation by suture was successfully performed in 28 eyes (84.8%) of 18 patients. Mean IOP decreased from 33.9 ± 9.4 mmHg preoperatively to 10.5 ± 3.5 mmHg at 6 months (p < 0.001) and 11.3 ± 4.1 mmHg at 9 months (p < 0.001). Complete success rate was 92.9% [95% confidence interval (CI:0.83-1.03)] and 87.5% (CI:0.69-1.06) at 6 months and 9 months, respectively. Hyphema was found in 5 eyes (17.9%), all of which were absorbed within 1 week. No other complications were observed.
conclusionsViscocanalostomy combined with nearly 360-degree suture trabeculotomy as a novel technique controls IOP in patients with PCG without any severe complications. It is suitable for extended applications because of accurate identification of Schlemm's canal and low cost.
