➔ Glaucoma Treatment
Glaucoma is the second leading cause of blindness in the world, according to the World Health Organization. Estimates put the total number of suspected cases of glaucoma at around 65 million worldwide.
It is a group of eye diseases that gradually steal sight without warning. In the early stages of the disease, there may be no symptoms. Experts estimate that half of the people affected by glaucoma may not know they have it.
Four Key Facts About Glaucoma
Glaucoma is a leading cause of blindness
There is no cure (yet) for glaucoma
Everyone is at risk for glaucoma
There may be no symptoms to warn you
Vision loss is caused by damage to the optic nerve. This nerve acts like an electric cable with over a million wires. It is responsible for carrying images from the eye to the brain.
There is no cure for glaucoma-yet. However, medication or surgery can slow or prevent further vision loss. The appropriate treatment depends upon the type of glaucoma among other factors. Early detection is vital to stopping the progress of the disease.
It was once thought that high pressure within the eye, also known as intraocular pressure or IOP, is the main cause of this optic nerve damage. Although IOP is clearly a risk factor, we now know that other factors must also be involved because even people with "normal" levels of pressure can experience vision loss from glaucoma.
What are the common types of glaucoma?
Adult glaucoma falls into two categories- open angle glaucoma and closed angle glaucoma . These are marked by an increase of intraocular pressure (IOP), or pressure inside the eye. When optic nerve damage has occurred despite a normal IOP, this is called normal tension glaucoma. Secondary glaucoma refers to any case in which another disease causes or contributes to increased eye pressure, resulting in optic nerve
Symptoms of angle closure glaucoma may include headaches, eye pain, nausea, rainbows around lights at night, and very blurred vision.
