Outcome of Ahmed glaucoma valve implant in congenital fibrovascular pupillary membrane with secondary glaucoma.
Article in BMC ophthalmology, 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
backgroundCongenital fibrovascular pupillary membranes in secondary glaucoma (CFPMSG) is kind of refractory childhood glaucoma. The aim of the study is to evaluate the efficacy and safety of Ahmed glaucoma valve (AGV) implants in CFPMSG.
methodsTwelve patients with CFPMSG who underwent anterior chamber reconstruction (ASR) with a stable anterior chamber but uncontrolled intraocular pressure (IOP) underwent AGV implantation. Patients with a follow-up period of > 12 months were enrolled. Demographic data were collected. All patients underwent comprehensive ophthalmic examinations before and after surgeries, including IOP measurement, A- and B-scan ultrasonography, and ultrasound biomicroscopy (UBM), etc. Success was defined as postoperative intraocular pressure (IOP) ≤ 21 mmHg with (qualified success) or without (complete success) the use of glaucoma drugs.
resultsThe median age of enrolled patients was 15.1 ± 12.5 months old (range 4.5-46) and 58.3% of them were female. At last follow-up (32.0 ± 16.0 months), the average IOP was declined (postoperative: 18.7 ± 4.5 mmHg vs. preoperative: 29.0 ± 4.0 mmHg, p < 0.001). The number of glaucoma drugs decreased from 3 (range 2-3) to 1.5 (range 0-3) (P < 0.001), while the anterior chamber depth (ACD) remained stable (3.21 ± 0.70 mm and 3.40 ± 0.82 mm, respectively) (p = 0.57) after AGV implantation. The complete success rate was 25% (3/12) and the qualified success rate was 58.3% (7/12). The total success rate was 83.8%. No severe complications were noted.
conclusionsThis study demonstrated that AGV implants could be safe and effective for CFPMSG with uncontrolled IOP. AGV implantation is a feasible option for the treatment of CFPMSG.
