目的:评价HAD房水引流物植入术中,经巩膜隧道植入引流管,调控引流管房水引流量对治疗难治性青光眼在降低手术并发症,提高手术成功率的作用。方法:对23例难治性青光眼,手术施行HAD房水引流物植入术,经巩膜隧道植入引流管,术后观察眼压、视力、前房深度及引流管暴露情况。术后随访6～21个月,平均随访13.7个月。结果:术前平均眼压(48.52±15.36)mmHg(1kPa=7.5mmHg),术后1个月眼压(12.32±4.57)mmHg,眼压平均下降率95.65%。术后末次随访眼压,不用降眼压药或局部滴降眼压药,眼压在21mmHg以下的20只眼,手术成功率为86.96%。视力:术后视力改善者9例,不变者12例,下降者2例。主要并发症:术后前房出血4例,占11.8%,无一例引流管暴露。结论:经巩膜隧道HAD房水引流物植入术,及术中调控引流管房水引流量为治疗难治性青光眼提供了一种安全、有效的方法。
OBJECTIVE: To evaluate the effect of aqueous hysterectomy (HAD) drainage on the drainage of the aqueous humor through the scleral tunnel, and to control the drainage of aqueous humor in the drainage tube for the treatment of refractory glaucoma in reducing the complications and improving the success rate of operation. Methods: Twenty - three patients with refractory glaucoma underwent HAD aqueous humor implantation and drainage via scleral tunnel. The intraocular pressure, visual acuity, anterior chamber depth and drainage tube were observed. The patients were followed up for 6 to 21 months with an average follow-up of 13.7 months. Results: The preoperative mean IOP was 48.52 ± 15.36 mmHg (1kPa = 7.5mmHg) and the intraocular pressure was 12.32 ± 4.57 mmHg at 1 month after operation. The average IOP decreased 95.65%. The postoperative follow-up intraocular pressure, without lowering intraocular pressure or local drip IOP, intraocular pressure in 20 eyes below 21mmHg, the success rate was 86.96%. Visual acuity: 9 cases of postoperative visual acuity improvement, unchanged in 12 cases, decreased in 2 cases. The main complications: 4 cases of postoperative anterior chamber hemorrhage, accounting for 11.8%, no case of drainage tube exposure. Conclusion: It is a safe and effective method to treat intractable glaucoma through transplanted HAD aqueous humor through scleral tunnel and intraoperative drainage of aqueous humor.
