概括
眼睛超声波 (OUS) 上的新月标志显示在检测高内压力 (ICP) 时具有中等的准确性. 这种非侵入性方法可以帮助ICP评估,尽管需要进一步的研究.
科学领域:
- 神经学 神经学
- 眼科医生 眼科 眼科
- 医疗成像医学成像
背景情况:
- 腰部穿刺 (LP) 是对内压力 (ICP) 评估的黄金标准,但存在风险.
- 对于高ICP的非侵入性眼睛超声波 (OUS) 方法显示了不同的结果.
- 特定OUS发现的诊断实用性,就像新月标志一样,需要进一步调查.
研究的目的:
- 确定OUS上半月标志的频率和测试特征,以提高ICP.
- 为了比较新月标志的表现与光神经外直径 (ONSD) 和光盘升高 (ODE).
主要方法:
- 对接受LP的成年患者进行前性观察队列研究.
- 眼睛超声波 (OUS) 在LP之前进行,用计量器测量开口压力 (OP).
- 升高的OP定义为≥25cmH2O. 升高的OP定义为≥25cmH2O.
主要成果:
- 分析了61名患者,15名患者的ICP升高.
- 在31%的患者中出现了新月标志.
- 半月符号显示了67%的灵敏度,80%的特异性和74%的准确性,用于高的ICP.
结论:
- 在OUS上的新月标志对于检测升高的ICP具有中等准确性.
- 需要在急性护理机构进行进一步的评估.
- 在各种OUS发现的测试特征之间没有发现显著差异.

Glaucoma: Overview
502
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
434
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...
