概括
使用Centurion系统在发酵性白内障手术期间降低输液压力不会影响手术效率或并发症. 这种较低的压力可能会导致视网膜微血管结构的短期变化较少.
科学领域:
- 眼科医生 眼科 眼科
- 手术创新 在外科创新.
- 视网膜微血管研究研究
背景情况:
- 化传统上使用高眼内压 (IOP) 来管理封闭后的吸收激增.
- 在白内障手术期间,新的流体系统使得更低,更生理的内压在白内障手术期间.
- 减少IOP对手术结果和眼部参数的影响需要研究,特别是在患有并存疾病的患者中.
研究的目的:
- 为了比较使用Centurion主动哨兵系统在发酵过程中低 (30 mmHg) 与高 (60 mmHg) 输液压的影响.
- 评估对白内障和糖尿病视网膜病变或青光眼患者手术效率,并发症和临床/成像参数的影响.
主要方法:
- 一个蒙面观察者随机控制可行性试验.
- 患有白内障和糖尿病视网膜病变或初级开角绿内障的患者被随机分配为低 (30 mmHg) 或高 (60 mmHg) 的输液压.
- 手术指标,临床变量和成像参数在术前和术后进行测量.
主要成果:
- 低输液压组和高输液压组之间没有观察到手术效率 (例如,累积消散能量) 或手术内并发症的显著差异.
- 手术后的眼内压力和角膜并没有显著的群体间差异.
- 较低的输液压力 (30 mmHg) 与较高的压力 (60 mmHg) 相比,导致状血管区和表面血管密度的短期变化较少.
结论:
- 使用Centurion主动哨兵系统的30 mmHg输液压是安全的,与60 mmHg相比,不会损害手术效率或增加并发症.
- 较低的输液压力可能通过减少视网膜微血管结构的短期变化而带来好处.
- 需要进一步的研究来确定这些微血管变化的长期临床意义.

Open Angle Glaucoma: Treatment
356
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.

Glaucoma: Overview
469
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...

Angle Closure Glaucoma: Treatment
365
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...
