目的探讨粘弹剂在高眼压状态下小梁切除术中的应用效果。方法对35例经充分降压后眼压仍很难降至正常的青光眼患者,在高眼压状态下行复合式小梁切除术,术中应用粘弹剂,所有患者随访8～12个月,观察术后视力、眼压、前房及并发症情况。结果所有患者手术顺利,术后眼压控制在10～21 mm Hg,4例需要加用药物控制。术中、术后未出现爆发性脉络膜上腔出血、恶性青光眼等严重并发症。结论在高眼压状态下小梁切除术联合应用粘弹剂可以保证手术效果,并提高手术的安全性。
Objective To investigate the effect of viscoelastic in trabeculectomy under high intraocular pressure (IOP). Methods 35 cases of glaucoma after intraocular pressure was still difficult to be reduced to normal after sufficient decompression were treated with compound trabeculectomy under high intraocular pressure. All patients were followed up for 8 to 12 months. Postoperative visual acuity, intraocular pressure, anterior chamber and complications were observed. Results All patients underwent a successful operation. The postoperative IOP was controlled at 10-21 mm Hg. Four patients needed drug control. No intraoperative and postoperative burst choroidal hemorrhage, severe complications such as malignant glaucoma. Conclusion Under the condition of high intraocular pressure, trabeculectomy combined with viscoelastic can ensure the operation effect and improve the safety of operation.
