Ectopic Filtering Bleb After Ahmed Glaucoma Valve Implantation Treated With Transconjunctival Mattress Sutures: A Case Report.
Article in Cureus, 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
Giant bleb formation is an uncommon complication following Ahmed glaucoma valve implantation and has most often been described in association with localized encapsulation around the valve plate. We report the case of a 74-year-old man with pseudoexfoliation glaucoma who developed a large cystic inferonasal bleb six weeks after pars plana implantation of an Ahmed glaucoma valve in the inferotemporal quadrant of the right eye. At presentation, the intraocular pressure was 7 mmHg, and slit-lamp examination suggested communication between the base of the bleb and the valve plate. The bleb was drained, and two transconjunctival horizontal mattress sutures were placed at the presumed site of communication. Following surgery, the ectopic bleb regressed completely, and intraocular pressure remained stable throughout follow-up for 10 months. This case suggests that ectopic bleb formation may arise through mechanisms other than encapsulation, likely related to redistribution of aqueous humor along adjacent subconjunctival tissue planes. In such cases, transconjunctival suturing may represent an effective approach to limit bleb expansion while preserving implant function.
