Glaucoma is a
family of diseases that affects pressure within the eye,
damaging the optic nerve. When pressure inside the eye
increases, blind spots in peripheral areas of vision may occur.
Of all conditions and diseases of the eye, glaucoma is one of
the leading causes of blindness in the United States. Often
called the "silent thief" of sight, most forms of glaucoma do
not produce symptoms until vision is already severely damaged.
But if diagnosed early, the disease can be controlled and
permanent vision loss can be prevented.
