概括
活动流体系统 (AFS) 程序在白内障手术后比重力流体系统 (GFS) 更好地保持斑点和光盘微循环. 对于需要仔细管理眼血管系统的患者来说,AFS可能是更好.
科学领域:
- 眼科医生 眼科 眼科
- 微循环研究 微循环研究
- 手术技术 手术技术
背景情况:
- 白内障手术是一种常见的手术.
- 手术后的微循环变化尚未完全理解.
- 流体系统可能会影响眼睛组织.
研究的目的:
- 在主动流体系统 (AFS) 和重力流体系统 (GFS) 白内障手术后比较微循环变化.
- 使用光学连贯断层扫描血管造影 (OCTA) 来评估黄斑和光盘微循环.
- 确定血管密度和视网膜神经纤维层厚度的最早的术后变化.
主要方法:
- 42只没有并发症的白内障眼睛被随机分为AFS (21只眼睛) 和GFS (21只眼睛) 组.
- 在手术前和手术后30分钟,24小时和7天进行了OCTA成像.
- 关键指标包括黄斑深毛细管血管密度和周毛细管血管密度.
主要成果:
- 手术后30分钟,AFS和GFS组之间没有立即观察到差异.
- 在24小时后,AFS组的斑点深毛细管血管密度明显高于GFS组 (42.2%对37.9%,p=0.048).
- 在7天后,与AFS相比,GFS组增加了鼻腔和下视网膜神经纤维层厚度,并降低了下周囊血管密度.
结论:
- 活体流体系统 (AFS) 程序证明了在白内障手术后对黄斑和光盘微循环产生保护作用.
- 对于患有影响眼血管系统的预先存在疾病的患者来说,AFS可能是一个更安全的选择,例如糖尿病或青光眼.
- 这项研究强调了流体学系统选择在尽量减少手术对眼睛微循环的影响方面的重要性.

Glaucoma: Overview
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...
Open Angle Glaucoma: Treatment
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.
