What is Glaucoma?
Glaucoma is an ocular disease normally associated with
pressure inside the eye. This pressure is too high for the continued health
of the optic nerve. The damage caused to the optic nerve progressively
leads to impaired vision. Glaucoma doesn't display any outward symptoms.
Most people don't know anything is wrong until they start to lose some
of their sight.
The fluid inside the eye, called the aqueous humor, normally
nourishes the structures inside the eye and is constantly replenished,
but in a patient with glaucoma, it fails to drain normally, thus the intraocular
pressure increases causing damage to the optic nerve.
Although there is no cure for glaucoma, with early diagnosis
and treatment, the pressure inside the eye can usually be controlled and
further vision loss either prevented or at least delayed.
Who is at risk?
There are certain groups of people who are at greater
risk for developing the disease:
- Individuals over the age of 40
- African Americans
- People with diabetes
- Family history of glaucoma
- People who are nearsighted
- Patients who have had long-term steroid treatment
- Those who have had an eye injury
- People with high blood pressure
Even if you do not fall into any of these categories, you
could still be at risk for developing the disease. Glaucoma can only be
recognized through a comprehensive eye examination.
