Glaucoma is an eye condition that causes an increase in pressure inside
the eye, leading to damage and lost eyesight.
Treatment for glaucoma depends upon the type of glaucoma affecting your vision. There are many
types of glaucoma, although the majority of cases fall into one of two
categories and are caused by aging of the eye.
Open-angle glaucoma is by far the most common form of glaucoma. It may
also be called primary or chronic glaucoma, and is responsible for approximately
90% of glaucoma cases. The name open-angle glaucoma indicates that the
angle between the iris and cornea is normal. Increased pressure inside
the eye is due to buildup inside the fluid drainage canals. This buildup
occurs slowly, and there are often no symptoms associated with open-angle
glaucoma as the condition progresses gradually.
Although less common, angle-closure glaucoma accounts for approximately
10% of cases. Angle-closure glaucoma occurs when the drainage canals are
blocked suddenly, and is characterized by an abnormally narrow angle between
the cornea and iris. This type of glaucoma occurs quickly and should be
considered an emergency. Prompt treatment is necessary to relieve the
rapid increase in intraocular pressure and prevent serious damage to your
vision. Symptoms of angle-closure glaucoma include eye pain, headaches,
nausea, and blurred vision.
Other Types of Glaucoma
There are many
other forms of glaucoma, although the majority of these are variations of either open-angle or
angle-closure glaucoma. These include secondary glaucoma caused by another
disease or condition, trauma-induced glaucoma, and congenital or childhood
glaucoma. Additionally, some people experience damage to the optic nerve
even without increased pressure inside the eye. This condition is called
normal-tension glaucoma, and its causes remain unknown.
Glaucoma can be treated to preserve or improve your vision.
