1 · What the graph read from it

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.

2 · The registry

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 investigate the incidence and clinical characteristics of malignant glaucoma (MG) following Preserflo MicroShunt (PMS) implantation. STUDY

designRetrospective multicenter cohort study

methodsWe investigated 957 consecutive eyes that underwent PMS implantation between August 2022 and May 2025. In all eyes, patient age, sex, glaucoma subtype, preoperative intraocular pressure (IOP), medication score, axial length (AL), and use of intraluminal suture stenting (ISS) were examined. We identified cases in which MG developed postoperatively and compared age, preoperative IOP, medication score, and AL between the MG and non-MG groups. The timing of MG onset and treatment outcomes were also evaluated. After Bonferroni correction, the adjusted significance level was set at P<0.0125 (0.05/4).

resultsMG occurred in 4 eyes (0.42%) of 2 men and 2 women, with a median age of 85.5 years (interquartile range [IQR], 84-90 years). All eyes were diagnosed with exfoliation glaucoma (XFG). Patients in whom MG developed were significantly older (P=0.006) and had a significantly higher preoperative IOP (P=0.006) than those without MG. No significant differences in AL or medication score were observed between the groups. MG developed on postoperative days 2, 3, and 4 in 3 eyes without ISS. In 1 case with ISS, MG occurred 3 days after ISS removal, but not during ISS placement. All MG cases were successfully treated with irido-zonulo-hyaloido-vitrectomy, with or without pars plana vitrectomy.

conclusionsAlthough rare, MG can occur in the early postoperative period after PMS implantation, particularly in older patients with a high preoperative IOP.
