Open Angle Glaucoma: Treatment

391
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

507
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...

科学领域:

  • 眼科医生 眼科 眼科
  • 玻璃眼研究研究 玻璃眼研究
  • 视觉场分析 视觉场分析

背景情况:

  • 主要开角光眼 (POAG) 是不可逆转失明的主要原因.
  • 眼睛高血压治疗研究 (OHTS) 提供了关于POAG进展的关键数据.
  • 了解视野 (VF) 损失率对于管理POAG至关重要.

研究的目的:

  • 在OHTS参与者中量化POAG诊断前和之后的VF损失率.
  • 为了比较不同POAG亚型中的VF损失率 (光盘与VF缺陷).

主要方法:

  • 来自OHTS临床试验数据的前性分析.
  • 使用线性回归计算POAG前后诊断时期的平均偏差 (MD) 斜率的计算.
  • 包括每个时期至少有5个虚拟货币基金的参与者.

主要成果:

  • 在POAG诊断时的平均年龄为66.4岁; 56%是男性.
  • 在POAG后的VF损失率有所不同:所有POAG眼睛的VF损失率为-0.40dB/年,光盘POAG的VF损失率为-0.19dB/年,VFPOAG的VF损失率为-0.54dB/年.
  • 显著比例的VF POAG眼睛呈现出快速进展 (≥ -0.5dB/年在41%,≥ -1.0dB/年在21%).

结论:

  • 一些POAG患者经历了快速的VF损失,尽管临床监测.
  • 眼睛高血压的个体,特别是那些高风险的POAG,需要勤奋的随访.
  • 早期诊断和及时治疗对于减轻POAG视力损失至关重要.
