Angle Closure Glaucoma: Treatment

665
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...

Open Angle Glaucoma: Treatment

554
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...

科学领域:

  • 眼科 眼科
  • 眼的治疗方法
  • 手术技术

背景情况:

  • 治疗眼通常需要控制眼内压力 (IOP).
  • 连续波跨细胞凝血 (CW-TSCPC) 是一种已知方法来降低内血压.
  • 优化CW-TSCPC设置对于平衡有效性和安全性至关重要.

研究的目的:

  • 为了比较CW-TSCPC的两种不同设置的疗效和安全性.
  • 评估不同能量和持续时间对内血压控制和患者结果的影响.
  • 为了确定最佳的CW-TSCPC参数用于治疗青光眼.

主要方法:

  • 进行了一项前性,随机的,三重盲目的临床试验.
  • 成年玻璃眼患者接受CW-TSCPC,使用1250mW4秒 (A组) 或2000mW2秒 (B组).
  • 测量结果包括内压,视力敏度,药物使用,并发症和再干预率.

主要成果:

  • 两种CW-TSCPC设置在1,4至6个月和12个月实现了相似的IOP降低.
  • 乙组显示了较早减少药物使用的趋势
  • 复发率相似,但B组的复发情况更严重;A组的5名患者需要重新干预,而B组的3名患者需要重新干预.

结论:

  • 这两种CW-TSCPC设置都有效降低内压.
