概括
在巨细胞动脉炎 (GCA) 患者中,透视超声波 (TOS) 显示了视网膜动脉流量和视神经直径的减少,这表明尽管接受了治疗,眼血管功能仍然受损. 内GCA血管变化可能对治疗反应较差.
科学领域:
- 眼科 眼科
- 关节病学
- 血管医学
背景情况:
- 巨细胞动脉炎 (GCA) 是一种全身性血管炎,可能导致不可逆转的视力丧失.
- 需要仔细监测和评估治疗疗效.
- 通过轨道超声波 (TOS) 提供一种非侵入性方法来评估眼血管参数.
研究的目的:
- 使用TOS对新诊断的GCA患者进行纵向评估.
- 评估视网膜中枢动脉流速和视神经直径的变化.
- 将TOS发现与全身血管炎症和治疗反应联系起来.
主要方法:
- 在12个月内对新诊断的GCA患者进行前性队列研究.
- 对视网膜中枢动脉的最大抽缩速度 (PSV),终端透析速度 (EDV) 和视神经直径 (OND) 的连续TOS评估.
- 使用线性混合效应模型计算OMERACT巨细胞动脉炎超声波 (OGUS) 评分和分析.
主要成果:
- 在12个月的随访期间,PSV和OND显著下降.
- 症状眼睛的PSV和EDV显著增加.
- 基线和纵向OGUS得分与PSV,EDV和OND相关,表明正在进行的血管炎症.
结论:
- 在GCA患者中,TOS显示视网膜动脉流量和OND逐渐减少,表明持续的眼血管功能受损.
- 内血管的GCA变化可能对治疗的反应不如外血管.
- 这些发现支持GCA的共享病理生理机制,影响内和外血管.

Open Angle Glaucoma: Treatment
557
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
669
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
745
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...
