概括
青光眼患者在行走时,脚的最低清除率变化更大,这表明跌倒风险可能增加. 这种步态变化可能是疾病进展的指标,并且在青光眼中降落的风险.
科学领域:
- 眼科医生 眼科 眼科
- 生物力学 生物力学
- 老年学是一门学科.
背景情况:
- 玻璃眼是一种渐进的视神经病变,通常与视力受损有关.
- 在患有青光眼的人群中,步行障碍和跌倒风险增加是常见的.
- 了解不同认知负载下的步态动力学对于防摔策略至关重要.
研究的目的:
- 为了在单任务和双任务行走过程中比较青光眼患者和健康对照者之间的步行动力学,特别是最小脚清除 (MTC).
- 评估认知任务对绿眼病患者的步行参数的影响.
主要方法:
- 一项涉及19名青光眼患者和30名健康对照者的横截面研究.
- 空间时空步行参数,包括MTC,使用惯性测量单位进行测量.
- 参与者进行了单任务步行和双任务步行,涉及认知任务 (反应时间,N-Back,字母流利).
主要成果:
- 与对照组相比,青光眼患者的MTC变化系数明显高于对照组.
- 中等效果大小表明MTC的双重任务成本较低,而MTC双重任务成本较高.
- 这些发现表明改变了步态控制和增加了对眼倒的易感性.
结论:
- 青光眼患者表现出MTC变异性增加和双重任务成本的改变,这表明因倒而导致跌倒的风险更高.
- MTC的变化可能反映了与疾病相关的步行表现的变化,并作为眼落风险的预后标志物.

Open Angle Glaucoma: Treatment
456
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
592
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
515
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...
