Short-term efficacy and safety of A-stream glaucoma shunt: a 6-month study.
Article in Eye (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThis study evaluated the short-term efficacy and safety of the A-stream Glaucoma Shunt (A-stream; MICROT Inc., Republic of Korea) in patients who completed 6 months of follow-up after implantation.
methodsMedical records of 49 patients (49 eyes) who underwent A-stream implantation between October 2023 and February 2024 were retrospectively reviewed. Primary outcomes included surgical success and intraocular pressure (IOP) reduction at 6 months postoperatively. Success was defined as achieving an IOP ≤ 18 mmHg, with at least a 20% reduction from preoperative IOP, and without clinically significant hypotony (IOP < 6 mmHg persisting >1 month or with hypotony maculopathy), classified as qualified (with or without medications) or complete (without medications). Ripcord removal timing and its effect on IOP, postoperative interventions, and complications were analysed.
resultsAt 6 months, the mean IOP significantly decreased from 26.9 ± 8.3 mmHg to 11.9 ± 3.5 mmHg (P < 0.01). Complete success was achieved in 77.6% and qualified success in 93.9% of the eyes. The ripcord was removed in 73.5% of eyes at an average of 1.8 ± 1.3 months postoperatively, which led to further IOP reduction of 6.8 ± 5.0 mmHg 1 month after removal. No cases of clinically significant hypotony or vision-threatening complications were observed.
conclusionsThe A-stream demonstrated excellent short-term efficacy and safety in lowering IOP with high success rates. The ripcord enabled controlled IOP adjustments postoperatively. Further studies are warranted to evaluate long-term outcomes and compare them with conventional surgeries.
