概括

与健康个体相比,正常张力玻璃眼 (NTG) 患者的脉动性气管网 (TM) 运动减少,但仍然高于初级开角玻璃眼 (POAG) 患者. 与POAG不同的是,NTG在TM运动中没有不对称性.

科学领域:

眼科眼科
生物医学工程
大眼的研究

背景情况:

眼是导致不可逆转失明的主要原因.
脊柱状网络 (TM) 功能障碍与青光眼的发病有关.
了解TM的生物力学对于诊断和治疗青光瘤至关重要.

研究的目的:

为了比较正常张力格劳科马 (NTG) 患者的脉动性TM运动与健康对照患者和初级开角格劳科马 (POAG) 患者.
在NTG和POAG中调查与视野缺陷严重程度相关的TM运动变化.

主要方法:

一项涉及15名健康患者,14名NTG患者和15名POAG患者的横截面研究.
使用定制的相位敏感光学连贯断层扫描系统来测量TM运动.
在部和鼻部分析的最大速度 (MV) 和累积移位 (CDisp).

主要成果:

与健康对照组相比,NTG患者的MV和CDisp显著降低 (p< 0. 001).
与POAG患者相比,NTG患者的MV和CDisp较高 (p< 0. 001).
轻度至中度视野缺陷 (GI) 的POAG眼睛的TM运动参数高于严重缺陷 (GII),而NTG在GI和GII之间没有显著差异.

结论:

脉动性TM运动在NTG中受损,但不如POAG.
在NTG中没有TM运动不对称,这表明其他因素有助于疾病的进展.
在NTG与POAG的进展中,TM生物力学可能起着不同的作用.

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Glaucoma: Overview

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...

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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...
