Gonioscopy-assisted transluminal trabeculotomy for intractable ocular hypertension after repeated intravitreal dexamethasone implant injections.

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 efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in managing intractable ocular hypertension (OHT) following repeated intravitreal dexamethasone implant (DI) injections.
methodsThis retrospective study included patients with steroid-induced OHT unresponsive to maximum tolerated medical therapy who underwent GATT. Primary outcome measures were intraocular pressure (IOP) reduction and surgical success (qualified and complete), number of DI injections.
resultsFourteen eyes of 14 patients (mean age: 66.2 ± 8.3 years) with steroid-induced OHT following repeated DI injections were analyzed. The mean number of DI injections before surgery was 4.2 ± 1.1 over a median period of 18.4 months (range: 12-36 months). The mean preoperative IOP was 33.6 ± 4.1 mmHg, which significantly decreased to 13.5 ± 2.9 mmHg at the first postoperative month (59.8% reduction, p < 0.001) and remained stable at 14.2 ± 3.1 mmHg at final visit. Qualified success was achieved in 100% of cases, while complete success was 71.4%. The mean number of glaucoma medications decreased from 3.1 ± 0.4 preoperatively to 0.4 ± 0.8 postoperatively.
conclusionGATT is a highly effective surgical option for treating intractable steroid-induced OHT following repeated DI injections, achieving significant and sustained IOP reduction while minimizing medication dependence.
