Long-term Outcomes of Trabeculectomy Versus Ahmed Glaucoma Valve Implantation in Vitrectomized Eyes.
Article in Beyoglu eye journal, 2025. 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
Objectives: This study compares the long-term outcomes and success rates of trabeculectomy and Ahmed glaucoma valve (AGV) implantation in vitrectomized eyes. Methods: This study included 58 eyes of 58 patients who had undergone pars plana vitrectomy and subsequently received either trabeculectomy (25 eyes) or AGV implantation (33 eyes) at our hospital between March 01, 2017 and April 01, 2023 and had at least 1-year follow-up. Complete success was defined as maintaining an intraocular pressure (IOP) between 5 and 21 mmHg without medication, whereas overall success was defined as achieving the same IOP range with or without medication. Failure was defined as an IOP exceeding 21 mmHg or falling below 5 mmHg, visual deterioration to light perception due to glaucoma progression or complications from glaucoma surgery, or the need for further glaucoma surgery. Results: The complete success was higher in the trabeculectomy group. Whereas both groups' overall success rates were similar at the last follow-up (p=0.04). Both groups demonstrated a comparable failure rate (p=0.44). The probability of success in the trabeculectomy group was 92.0% at 12 months, 88.0% at 24 months, and 84.0% at 36 months, whereas in the AGV group, it was 87.8% at 12 months, 81.8% at 24 months, and 75.7% at 36 months. There was no difference in terms of post-operative complication rate in both groups. (p=0.36). Conclusion: Both AGV implantation and trabeculectomy yield comparable outcomes in vitrectomized eyes. However, trabeculectomy reduced the requirement for antiglaucoma medications postoperatively. Consequently, trabeculectomy may be a viable option in carefully selected vitrectomized eyes.
