Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

630
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: Overview01:25

Glaucoma: Overview

829
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: Treatment01:28

Angle Closure Glaucoma: Treatment

759
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...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

科学领域:

  • 眼科 眼科
  • 预防医学
  • 公共卫生

背景情况:

  • 眼病是美国不可逆转失明的主要原因,
  • 据估计,美国有270万人患有青光眼.
  • 美国预防服务工作组 (USPSTF) 在2013年发布了建议.

研究的目的:

  • 进行系统审查以更新2013年USPSTF关于青光眼查的建议.
  • 评估成年人群中青光眼查的潜在益处和危害.

主要方法:

  • 一个系统的审查是由USPSTF委托.
  • 这项审查集中在40岁及以上的成年人,在初级保健中没有开角眼的症状.

主要成果:

  • 目前的证据不足以评估青光眼查对成年人的益处和危害的平衡.
  • 与查眼相关的益处和危害仍然不确定.

结论:

  • USPSTF认为,没有足够的证据支持或反对对成年人进行初级开角青光眼的查.
  • 需要进一步研究以澄清青光眼查方案的有效性和安全性.
