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

introductionThe aim of the study was to investigate the clinical characteristics and treatment outcomes of the pseudophakic eyes with malignant glaucoma (MG).

methodsThis retrospective case-control study enrolled 53 eyes of 47 patients with primary angle-closure glaucoma having cataract surgery history, including 19 patients (25 eyes) diagnosed with MG and 28 patients (28 eyes) without MG as the match. Among patients diagnosed with MG, 14 patients (18 eyes) underwent zonulo-hyaloido-vitrectomy (ZHV) and the other 5 patients (7 eyes) received conservative treatments. The visual acuity, refraction status, intraocular pressure (IOP), extent of peripheral anterior synechia, classes of anti-glaucoma medications, and ultrasound biomicroscopy (UBM) examination were recorded before cataract surgery, at the diagnosis of MG, and 3 months after ZHV or atropine application, respectively.

resultsIn the pseudophakic eyes with MG, the IOP cannot be well controlled compared to the matched eyes (27.24 ± 8.72 mm Hg vs. 14.30 ± 2.63 mm Hg, p < 0.001). In addition, there was a difference in the average spherical equivalent refractive error between 2 groups of patients (-2.23 ± 0.84 D in MG vs. -0.12 ± 0.64 D in the matched eyes, p < 0.001). By UBM analysis, the anterior chamber depth (ACD) was shallower in MG than that in the matched eyes (2.34 ± 0.20 mm vs. 3.47 ± 0.29 mm, p < 0.001). The difference between the anterior vault distance of the pseudophakic eyes with MG and that of the matched eyes was also significant (p < 0.001). After treated with ZHV, the IOP was greatly decreased from 27.84 ± 10.14 mm Hg to 15.85 ± 4.41 mm Hg (p < 0.001). The refractive error also changed from -2.11 ± 0.91 D to +0.42 ± 0.99 D (p < 0.001). At the same time, the central ACD was significantly deepened from 2.30 ± 0.39 mm to 3.30 ± 0.31 mm (p < 0.001).

conclusionUncontrolled IOP and shallow anterior chamber both centrally and peripherally are the primary clinical characteristics for the pseudophakic eyes with MG. An unexpected refractive error or myopic shift for the eyes with PACG after cataract surgery can be an important hint for diagnosis of MG. The typical UBM image is an anterior displacement of the lens-iris diaphragm and a bow-shaped change of the intraocular lens. It is an effective way to treat pseudophakic MG with the ZHV through a peripheral iridectomy.
