概括
这项为期5年的研究发现,MicroShunt植入和带切除在初级开角眼 (POAG) 中是安全的. 虽然膜切除术降低了眼内压力,但MicroShunt的低血压并发症较少.
科学领域:
- 眼科 眼科
- 玻璃眼手术
- 医疗设备的安全性
背景情况:
- 主要开角眼 (POAG) 是不可逆转的失明的主要原因.
- 有效的手术对于治疗POAG和预防视力损失至关重要.
- 长期安全数据比较MicroShunt植入和气管切除术对于临床决策至关重要.
研究的目的:
- 在POAG患者中比较MicroShunt植入的长期安全性和有效性.
- 评估5年间的不良事件,眼内压力控制和药物使用情况.
- 评估每次手术后危及视力的副作用的累积发病率.
主要方法:
- 一个为期2年的预期随机试验的3年观察延期.
- 包括279名患有POAG的患者,接受了MicroShunt或轨道切除术,两者都增加了mitomycin C.
- 随机化后36,48,60个月记录副作用,内压和药物使用情况.
主要成果:
- 这两种方法在5年内都显示出良好的安全性.
- 与MicroShunt相比,管切除可以更大程度地降低内血压 (45%对26%).
- 与管切除术相比,MicroShunt的内脉压增加发生率更高,但需要治疗,但低血压和二次干预较少.
结论:
- 微冲刺植入和气管切除是对POAG的安全有效的长期手术选择.
- 在手术之间进行选择可能取决于平衡低血压的风险与降血压治疗的需要.
- 大多数AE并没有危及视力,也不需要重新手术.

Open Angle Glaucoma: Treatment
554
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
665
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Glaucoma: Overview
740
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
