Glaucoma
When the pressure increases in the eyeball causing damage to the optic nerve
and also causing a loss of vision the person who is affected is said to have
glaucoma. In the normal eye there is fluid, which is produced in the posterior
chamber. This fluid then passes through the pupil and into the anterior chamber
after which it drains through the outflow channels. Although a small amount of
pressure is required to keep the shape of the eyeball intact, when the flow of
this fluid is blocked by an obstruction the pressure increases producing blind
spots in the visual field and a loss of peripheral vision. There are several
types of glaucoma including open- angle glaucoma, subacute angle-closure
glaucoma, congenital glaucoma and closed-angle glaucoma. The most common type of
glaucoma seldom occurs before the age of 40 may have no symptoms at all until
some degree of blindness has occurred. Strong powered reading glasses that we
offer are used by people with emerging Macular Degeneration
patients.
With all forms of glaucoma the treatment is more successful if
it has began early in the condition. With open angle glaucoma medicated eye
drops are given to control the condition. With closed angle glaucoma there are
several medications that can be given to quickly decrease the pressure in the
eye and laser therapy is available to allow drainage. Acute closed angle
glaucoma is considered a medical emergency and is treated immediately either
laser surgery or medications to reduce the pressure. Glaucoma that is caused by
injury or disease will depend on the cause. In some cases corticosteroids are
given to decrease the inflammation with medication to keep the pupils
enlarged.
