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 evaluate reduction in intraocular pressure (IOP) and medications for open-angle glaucoma (OAG) patients 12 months post-ab-interno circumferential viscodilation (VISCO360, Sight Sciences, Menlo Park, CA) in conjunction with cataract surgery.

settingSurgical center (New York, United States).

designRetrospective study of all OAG patients treated with 360-degree ab-interno viscodilation with cataract surgery by a single surgeon (NR) having 12 months of follow-up. Eyes were stratified by baseline IOP. Group 1: ≥18 mmHg (n=111). Group 2: <18 mmHg (n=69).

methodsIOP was measured using Goldmann applanation tonometry. Medications, the number of medication-free eyes in each group at 12 months, and adverse events (AE) are reported. Analysis includes descriptive statistics and t-tests evaluating change from baseline.

resultsGroups 1 and 2 had mean baseline IOP of 22 and 14.3 mmHg. Medication use was 0.9 and 1.1 for Groups 1 and 2. At 12 months IOP for Group 1 was reduced 22% to 17.2 mmHg (p<0.0001) on 1.0 medications (p=0.7). IOP for Group 2 was similar to baseline (15.4 mmHg) but with a reduction in medications to 0.6 (p<0.05). The proportion medication free at 12 months was 32% and 47% for Groups 1 and 2 versus 34% and 26% at baseline, respectively. There were few AE (hyphema 1.7%, IOP elevation >10 mmHg >30 days post-op 1.1%, mild inflammation <1%) and no secondary surgical interventions excepting a single paracentesis, one-day postoperative. DISCUSSION: Treatment goals for the two groups differed. Pressure reduction (Group 1) or medication reduction (Group 2). Viscodilation achieved significant IOP reduction in Group 1 and medication reduction in Group 2 with many patients (both groups) medication free at 12 months. AE were infrequent and transient.

conclusionCircumferential ab-interno viscodilation can be combined with cataract surgery and provide an IOP lowering and medication reduction benefit sustained for at least 12 months, for many patients with OAG.
