Bilateral anterior lens luxation with secondary glaucoma strongly associated with self-application of a percussion massage gun to closed eyelids: a case report.
Article in BMC 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
backgroundPercussion massage guns (PMGs) have gained widespread popularity for muscle recovery; however, standardized safety guidelines for application to anatomically vulnerable regions are lacking. Previously reported PMG-associated ocular injuries have been limited to unilateral or mild bilateral involvement. We report the first documented case of bilateral anterior lens luxation with secondary glaucoma strongly associated with self-application of a PMG to closed eyelids. CASE PRESENTATION: A 62-year-old Chinese male with type 2 diabetes mellitus and bilateral meibomian gland dysfunction presented with progressive visual decline and headache for 20 and 10 days, respectively, beginning approximately 7 days after discontinuing self-application of a PMG to closed eyelids (medium speed, 30-33 Hz; 10 min per session, 2-3 times daily for 3 consecutive days) used to relieve ocular dryness. Visual acuity was 0.12 OD and 0.2 OS, with intraocular pressure 51 mmHg OD and 49 mmHg OS. Ultrasound biomicroscopy revealed bilateral anterior lens luxation with 360° zonular dehiscence and complete angle closure. Hereditary, pseudoexfoliative, and biometric causes (including microspherophakia and phacomorphic glaucoma) were considered unlikely. Both eyes underwent sequential 25-gauge pars plana vitrectomy with lensectomy and closed four-point scleral fixation of a posterior chamber intraocular lens. At the latest follow-up (12 months postoperatively), best-corrected visual acuity was 1.0 OD and 0.8 OS, intraocular pressure was normal without antiglaucoma medication, and no glaucomatous optic neuropathy was detected on RNFL OCT.
conclusionsPMG application to the eyelids may be associated with severe bilateral ocular injury, including complete zonular dehiscence and secondary glaucoma, particularly in eyes with predisposing factors such as age-related zonular weakness or diabetes-related extracellular matrix changes. Manufacturers should incorporate explicit safety warnings against periorbital use. Clinicians should proactively guide diabetic patients with dry eye disease toward appropriate ophthalmic care to prevent harmful self-treatment.
