Abstract Primary open angle glaucoma is a chronic optic neuropathy often requiring lifelong treatment. Patient compliance, adherence and persistence with therapy play a vital role in improved outcomes by reducing morbidity and the economic consequences that are associated with disease progression.
Where Can I Learn More? It occurs mainly in the over 50 age group. There are no symptoms associated with POAG.
The pressure in the eye slowly rises and the cornea adapts without swelling. If the cornea were to swell, which is usually a signal that something is wrong, symptoms would be present.
But as this is not the case, this disease often goes undetected.
It is painless, and the patient often does not realize that he or she is slowly losing vision until the later stages of the disease. However, by the time the vision is impaired, the damage is irreversible. In POAG, there is no visible abnormality of the trabecular meshwork.
It is believed that something is wrong with the ability of the cells in the trabecular meshwork to carry out their normal function, or there may be fewer cells present, as a natural result of getting older.
Others believe it is caused by an enzymatic problem. These theories, as well as others, are currently being studied and tested at numerous research centers across the country. Glaucoma is really about the problems which occur as a result of increased IOP. The average IOP in a normal population is millimeters of mercury mmHg.
In a normal population pressures up to 20 mmHg may be within normal range. A pressure of 22 is considered to be suspicious and possibly abnormal. However, not all patients with elevated IOP develop glaucoma-related eye damage.
What causes one person to develop damage while another does not is a topic of active research. As we mentioned earlier, this increased pressure can ultimately destroy the optic nerve cells.
Once a sufficient number of nerve cells are destroyed, blind spots begin to form in the field of vision.
These blind spots usually develop first in the peripheral field of vision, the outer sides of the field of vision. Once visual loss occurs, it is irreversible because once the nerve cells are dead, nothing can restore them at the present time. Later on, we will talk about the many ways your eye doctor can detect glaucoma in its earliest stages -- before any visual damage occurs.
POAG is a chronic disease.The most common is called primary open angle glaucoma. This tends to develop slowly over many years.
It's not possible to reverse any loss of vision that occurred before glaucoma was diagnosed, but treatment can help stop your vision getting worse. The treatment recommended for you will depend on the type of glaucoma you have, but the.
Primary open-angle glaucoma (POAG) is by far the most common type of glaucoma. Moreover, its frequency increases greatly with age and it is a chronic, not acute, disease. Moreover, its frequency increases greatly with age and it is a chronic, not acute, disease.
Primary Open Angle glaucoma (POAG) is the second commonest cause of registerable blindness and partial sight registrations in the UK (Bougard et al ). It is particularly dangerous because of its progressive nature and ability to go unnoticed for years thereby preventing treatment of the disease until, in some cases it can be too late to.
Some drugs can cause problems when taken with other medications. It is important to give your doctor a list of every medicine you take regularly. Your role in glaucoma treatment.
Treating glaucoma successfully is a team effort between you and your doctor. Your ophthalmologist will prescribe your glaucoma treatment.
PRIMARY OPEN-ANGLE GLAUCOMA (POAG) Glaucoma is really about the problems which occur as a result of increased IOP. The average IOP in a normal population is millimeters of mercury (mmHg).
It may be hereditary. There is no cure for it at present, but the disease can be slowed or arrested by treatment. Since there are no symptoms. Simple (primary) open-angle glaucoma . Simple (primary) open-angle glaucoma (POAG) is a progressive, chronic condition characterised by: Adult onset.
