In the treatment of
glaucoma, your eye doctor will try to
reduce the risk of damage to your optic nerve by keeping your eye pressure
(intraocular pressure, or IOP) from rising above a certain level. That level of
pressure is called your target pressure. By reducing the risk of optic nerve
damage, maintaining the target pressure in your eyes may help slow the
progression of the disease.
A tonometry test is used to measure the pressure in the eyes. The target
pressure is based on the degree of optic nerve damage, the amount of visual
field loss and, to a lesser degree, the initial pressure in the eye and how
widely it varies each time it is measured. The target pressure varies from
person to person. It is usually about 20% to 30% less than
the highest IOP you've had.
A prosthetic eye can help improve the appearance of people who have lost an eye to injury or disease. It's commonly called a "glass eye" or "fake eye."
The prosthetic eye includes:
oval, whitish outer shell finished to duplicate the white color of the other eye
round, central portion painted to look like the iris and pupil of the other eye
Implanting a prosthetic eye (ocular prosthesis) is almost always recommended after an eye is surgically removed due to damage or disease.
When the tonometry measurement is above target pressure, your doctor will consider making changes to your treatment, such as starting medicine or changing your medicine.
