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.
Primary congenital glaucoma (PCG) is an eye disease that affects children between the ages of birth and 3 years. It is one type of glaucoma. Glaucoma refers to a group of diseases in which there is permanent and characteristic damage to the optic nerve which is usually associated with abnormally high intraocular pressure.
Primary congenital glaucoma is rare. It affects about one in every 10,000 infants. But it is serious and needs attention. Untreated primary congenital glaucoma is a major cause...
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.
