The human eye is continually bathed in liquid that builds up and
then is filtered through drainage canals.
When something goes
wrong with these internal 'pipes', pressure can build up within
the eye and can eventually damage the optic nerve.
This condition is known as glaucoma. As people age, glaucoma develops silently and painlessly. At first, it may effect peripheral vision and present mild
symptoms including headaches, occasional blurred vision or
a dull pain in the eyes.

If left untreated, even the more common form of open angle glaucoma can lead to total blindness. The more serious
and rarer form of closed angle glaucoma arises more suddenly and can lead to total blindness within a few days, constituting
a medical emergency requiring immediate treatment.
Treatment options traditionally include glaucoma drugs and medications used to reduce fluid formation in the eye and thus relieve
pressure. Laser surgery for glaucoma is another more modern innovation that has also
proven to be safe and effective, as well.
