Five-year trends in primary open-angle glaucoma surgery: baseline characteristics preferences, and the impact of emerging techniques.
Article in International ophthalmology, 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
purposeTo evaluate the baseline characteristics of patients with open-angle glaucoma (OAG) who underwent primary glaucoma surgery between 2020 and 2024, and to analyze trends in surgical preferences.
methodsMedical records of patients older than 18 years who underwent primary glaucoma surgery were reviewed retrospectively. Surgical procedures included trabeculectomy, Ahmed Glaucoma Valve (AGV) implantation, gonioscopy-assisted transluminal trabeculotomy (GATT), Kahook Dual Blade (KDB), XEN Gel Stent implantation, and diode laser cyclophotocoagulation.
resultsA total of 1,192 eyes were included, and the annual number of operated eyes was 158 in 2020, 231 in 2021, 245 in 2022, 326 in 2023, and 232 in 2024. Age, IOP, BCVA, and glaucoma stage were similar across the years (all p > 0.05), whereas the number of preoperative medications was higher in 2020 than in the following years (p < 0.01). Across all years, surgery was performed most frequently in eyes with severe glaucoma, and trabeculectomy remained the most common procedure. In 2023 and 2024, the frequencies of trabeculectomy and AGV implantation decreased, whereas GATT increased and became the third most commonly performed procedure. The minimally invasive glaucoma surgery (MIGS) group included more mild-to-moderate cases and fewer severe cases, and had better BCVA and lower IOP than the non-MIGS group (all p < 0.05).
conclusionsBaseline characteristics remained largely stable over the five-year period, except for higher preoperative use of antiglaucoma medications in 2020. Surgical practice shifted toward GATT and MIGS in 2023 and 2024. Compared with the non-MIGS group, the MIGS group included a higher proportion of eyes with mild-to-moderate disease, while trabeculectomy remained the most commonly performed procedure overall.
