目的 :研究粘弹剂在重度前房积血 ( 、 级 )手术中的作用。方法 :将粘弹剂注入前房 ,利用其推力分离和娩出凝血块。结果 :32例 (32眼 )重度前房积血手术中较完整娩出凝血块 ,其中 18例伴有继发性青光眼 ,术后眼压恢复正常。随访 18～ 2 6个月 ,未见再出血 ,眼压正常。术后视力 0 .5以上者 2 5例占 78.12 % ,其中 1.0～ 1.5者 15例占 46 .87%。结论 :粘弹剂在重度前房积血手术中能起到安全有效地娩出凝血块 ,保护眼内组织 ,降低并发症的作用。 Objective: To study the role of viscoelastic in severe hyphema (grade) surgery. Methods: The viscoelastic injected into the anterior chamber, the use of its thrust separation and delivery of clots. Results: Thirty-two cases (32 eyes) with severe hyphema had a complete coagulation clot. Among them, 18 cases had secondary glaucoma and the intraocular pressure returned to normal. Follow-up 18 ~ 26 months, no further bleeding, intraocular pressure normal. Postoperative visual acuity more than 0.5 5 cases accounted for 78.12%, of which 1.0 to 1.5 of 15 cases accounted for 46.87%. Conclusion: Viscoelastic can effectively and effectively deliver clot in the treatment of severe hyphema, protect the intraocular tissues and reduce the complications.
