什么是青光眼?

The International Agency for the Prevention Blindness tells us “青光眼”一词指的是一组可以多种方式分类的疾病, 但这些疾病的特点都是视神经损伤和视野丧失.

人的眼睛里充满了一种清澈的液体,这种液体不断地生成,然后排出, always keeping the same amount of liquid in the eye.

When the opening that allows the liquid to drain is closed, more and more liquid will build up in the eye increasing the pressure. 随着时间的推移, 这种压力的增加会损害眼睛,导致视力下降,然后失明,无法逆转.

Imagine your eye is like a water tank – water flows in and water flows out. 如果出水口堵塞,水无法流出,水箱会破裂. To correct this, you must fix the outlet or put in a new outlet.

类型的青光眼

There are several types of glaucoma, these are:

  • Primary 开放 角青光眼 (POAG) which develops from an unknown cause
  • 原发性闭角型青光眼(PACG)是一种病因不明的青光眼,可引起剧烈疼痛
  • Secondary glaucoma which develops from a known cause, usually due to a serious eye injury, 白内障, 肿瘤, 或糖尿病
  • 发育性(先天性)青光眼是一种罕见的情况,发生在婴儿和儿童

青光眼的原因

青光眼的发展有许多危险因素. 这些包括:

  • 眼压升高
  • 年龄增加
  • 青光眼家族史
  • 种族背景
  • 眼睛受伤
  • 糖尿病
  • 远视(远视)
  • High myopia (shortsightedness)

青光眼 affects both adults and children. However the condition is more common in older age.

青光眼的症状

Different types of glaucoma present different symptoms.

开放 角青光眼 doesn't usually cause any symptoms to begin with. That's why eye screenings are so important for early detection. 这种情况往往会在多年后缓慢发展,首先影响周边视觉的边缘. Signs and symptoms include:

  • Gradual loss of peripheral vision, usually in both eyes
  • Tunnel vision in the advanced stages


闭角型青光眼 which can develop very suddenly. Signs and symptoms include:

  • 对光线敏感
  • 恶心和呕吐
  • 浑浊的眼睛
  • 晕周围的灯光
  • 严重的眼疼
  • 水汪汪的红眼睛
  • Poor vision and jerky eyes known as nystagmus

治疗青光眼

目前还没有治愈青光眼的传统疗法,但有一些疗法可以控制视力下降. Frequent eye screenings are critical for early detection and intervention.

治疗青光眼的眼药水

There are eye drops available to reduce the pressure in the eye. These drops must be used on a regular basis. The pressure inside the eye and side vision must be checked regularly too.

Laser treatment for glaucoma

激光治疗可以打开堵塞的引流管或减少眼睛内液体的产生. 治疗期间, 一束高能光束被小心地对准眼睛的一部分,以阻止液体在眼睛内积聚.

手术治疗青光眼

If eye drops and laser surgery are ineffective, surgery is advised. 青光眼最常见的手术是小梁切除术,它包括移除部分眼引流管,让液体更容易排出.

在婴儿, an operation is frequently performed to make small openings in the eye, allowing the extra fluid to drain.

What We’re Doing to Combat 青光眼 Around the World?

根据 International Agency for the Prevention of Blindness 据估计,到2020年将有大约8000万人患有青光眼, an increase of about 20 million since 2010.

Furthermore, it is thought that at present over 3.6 million people are blind due to glaucoma, and 4.2 million suffer severe vision impairment. 通过改进的眼部筛查和有效的治疗策略,可以控制患病率.

In many remote communities around the world, 由于缺乏高质量的眼科护理服务,以及人们对预防不必要失明的早期干预重要性的认识,青光眼患者失去了视力,并一直处于不可逆转的失明状态.
