To report a case of a tear in the trabecular meshwork caused by an airsoft gun, a toy that propels a plastic bullet.
Case report.
A 7-year-old Japanese boy sustained an ocular injury to the right eye from an airsoft gun. Ophthalmic examination 1 hour after the injury showed a best-corrected visual acuity in the injured eye of hand motion, corneal abrasion and edema, hyphema, and commotio retinae. Gonioscopy 6 days after the injury revealed a tear in the trabecular meshwork as well as an angle recession. Ultrasound biomicroscopy (UBM) strongly suggested that the tear extended into Schlemm's canal. Corneal abrasion and edema, hyphema, and commotio retinae resolved over 10 days, and best-corrected visual acuity improved to 20/15. Two months after the injury, the trabecular meshwork had not healed.
Airsoft guns can cause a full-thickness tear in the trabecular meshwork, which may contribute to development of late-onset glaucoma. UBM is useful to evaluate the tomographic features of the disrupted trabecular meshwork. The potential force of airsoft guns to cause substantial ocular injuries should be recognized. Wearing ocular protection should be mandatory while playing with airsoft guns.
报告一例由气枪（一种发射塑料子弹的玩具）导致的小梁网撕裂病例。
病例报告。
一名7岁日本男孩用气枪导致右眼眼部受伤。受伤1小时后的眼科检查显示，受伤眼的最佳矫正视力为手动，存在角膜擦伤和水肿、前房积血以及视网膜震荡。受伤6天后的房角镜检查显示小梁网撕裂以及房角后退。超声生物显微镜检查（UBM）强烈提示撕裂延伸至施莱姆管。角膜擦伤和水肿、前房积血以及视网膜震荡在10天内消退，最佳矫正视力提高到20/15。受伤两个月后，小梁网仍未愈合。
气枪可导致小梁网全层撕裂，这可能会促使迟发性青光眼的发生。UBM有助于评估受损小梁网的断层特征。应认识到气枪造成严重眼部损伤的潜在力量。玩气枪时必须佩戴眼部防护装备。
