To report long-term (>5 years) success of non-penetrating filtering surgery in glaucoma due to elevated episcleral venous pressure.
Observational case report.
A 25-year-old woman developed severe glaucoma due to elevated episcleral venous pressure. Nonpenetrating filtering surgery (opening of the Schlemm canal and resection of corneal stroma overlying the trabecular meshwork and Descemet membrane) was performed with mitomycin. Three months later, the meshwork was perforated ab interno by neodymium:yttrium-aluminum-garnet laser via goniolens (goniopuncture).
There were no complications, and no glaucoma medications were used postoperatively. Intraocular pressure ranged from 10 mm Hg to 18 mm Hg during the first 4 months and thereafter between 6 mm Hg and 12 mm Hg.
Glaucoma due to elevated episcleral venous pressure, an entity associated with significant trabeculectomy risks, can be safely and successfully treated with non-penetrating filtering surgery followed by goniopuncture (staged trabeculectomy).
报告非穿透性滤过手术治疗巩膜静脉压升高所致青光眼的长期（>5年）成功率。
观察性病例报告。
一名25岁女性因巩膜静脉压升高患上严重青光眼。采用丝裂霉素进行非穿透性滤过手术（开放施莱姆管并切除小梁网和Descemet膜上方的角膜基质）。三个月后，通过前房角镜用钕：钇铝石榴石激光从眼内穿刺小梁网（前房角穿刺）。
无并发症发生，术后未使用青光眼药物。最初4个月眼压范围为10 mmHg至18 mmHg，此后为6 mmHg至12 mmHg。
巩膜静脉压升高所致青光眼是一种与小梁切除术显著风险相关的疾病，采用非穿透性滤过手术联合前房角穿刺（分期小梁切除术）可安全、成功地进行治疗。
