Trabecular meshwork peeling technique of ab interno trabeculectomy - A retrospective review.
Article in Indian journal of 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 assess 1-year outcomes of the trabecular meshwork peeling technique of ab interno trabeculectomy in patients with glaucoma.
methodsThis retrospective study reviewed medical records of 117 eyes from 117 glaucoma patients who underwent trabecular peeling (TRAP) surgery alone or combined with cataract surgery (TRAP-CS) at a single eye center. All procedures were performed by a single surgeon between June 1, 2016 and December 31, 2019. The surgery involved ab interno removal of 120 to 360 degrees of the trabecular meshwork using microforceps. The primary postoperative outcomes evaluated included changes in intraocular pressure (IOP), use of anti-glaucoma medications (AGMs), complications, and surgical success over a 1-year follow-up period.
resultsThe mean IOP reduced from a preoperative value of 21.58 ± 7.20 mm Hg to 14.5 ± 3.8, 14.9 ± 3.4, 15.0 ± 3.6, and 14.6 ± 3.4 mmHg at 1 month, 3 months, 6 months, and 1 year after surgery, respectively (P < 0.001). The use of AGM significantly reduced from 2.47 ± 1.01 before surgery to 0.50 ± 0.9 at 1 year after surgery (P < 0.001). The percentage reduction in IOP and AGM at 1 year postoperatively was 31.3% and 80.0%, respectively. The absolute and qualified success rates at 12 months after surgery were 56.0% and 75%, respectively (point success at 12 months: 68.5% absolute and 89.2% qualified). Two cases required resurgery. No significant complications were noted.
conclusionsThis study shows that the TRAP technique of ab interno trabeculectomy is a safe and effective approach to reducing IOP in patients with glaucoma.
