Glaucoma is a type of optic neuropathy. Glaucoma has been nicknamed the "sneak thief of sight" because the loss of vision normally occurs gradually over a long period of time and is often only recognized when the disease is quite advanced.
Eye tests can pick up glaucoma.
Raised intraocular pressure is a significant risk factor for developing glaucoma (above 22mmHg). This can cause a person's sight to deteriorate and can lead to blindness. One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressure for years and yet never develop damage. Glaucoma occurs when the nerve at the back of the eye becomes damaged. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.
FACTS ABOUT GLAUCOMA
Glaucoma is a leading cause of blindness. There is no cure for glaucoma—yet. Everyone is at risk. There may be no symptoms.
GLAUCOMA IS A LEADING CAUSE OF BLINDNESS
Glaucoma can cause blindness if it is left untreated. And unfortunately approximately 10% of people with glaucoma who receive proper treatment still experience loss of vision.
THERE IS NO CURE (YET) FOR GLAUCOMA
Glaucoma is not curable, and vision lost cannot be regained. With medication and/or surgery, it is possible to halt further loss of vision. Since glaucoma is a chronic condition, it must be monitored for life. Diagnosis is the first step to preserving your vision.
EVERYONE IS AT RISK FOR GLAUCOMA
Everyone is at risk for glaucoma from babies to senior citizens, older people are at a higher risk for glaucoma but babies can be born with glaucoma . Young adults can get glaucoma, too.
THERE MAY BE NO SYMPTOMS TO WARN YOU
With open angle glaucoma, the most common form, there are virtually no symptoms. Usually, no pain is associated with increased eye pressure. Vision loss begins with peripheral or side vision. You may compensate for this unconsciously by turning your head to the side, and may not notice anything until significant vision is lost. The best way to protect your sight from glaucoma is to get tested. If you have glaucoma, treatment can begin immediately.
WHAT IS GLAUCOMA?
Glaucoma is the name given to a group of conditions that affect the eye. Increased intraocular pressure (IOP) resulting either from a malformation or malfunction of the eye’s drainage structures causes Glaucoma. Left untreated, an elevated IOP causes irreversible damage the optic and retinal fibers resulting in a progressive, permanent loss of vision. However, early detection and treatment can slow, or even halt the progression of the disease.
TYPES OF GLAUCOMA
There are four different types of glaucoma - acute, chronic, developmental and secondary. In each case, the optic nerve behind the eye is damaged. This nerve carries information from the eye to the brain enabling us to see. This damage can be caused by a weak nerve or more usually by the build-up of fluid in the eye. This occurs when fluid in the eye cannot drain properly.
Acute glaucoma can occur suddenly and can be painful. If left untreated, it can lead to blindness.
Chronic glaucoma is the most common form of the condition. The drainage channels from the eye become blocked over time and vision gradually becomes impaired.
Developmental glaucoma mostly affects babies and young children. It is rare but potentially serious and is caused by malformation of the eye.
Secondary glaucoma occurs when another problem in the eye causes fluid to build-up and eyesight to deteriorate.
HOW COMMON IS IT
By the age of 40, about one person in every 100 has some form of glaucoma. However, the incidence rises steadily as people get older. By the age of 70, about one person in every 10 has some form of glaucoma. People who are of African origin are more likely to develop the condition. People who are highly short-sighted, those with diabetes and those with a family history are also at increased risk.
WHAT ARE THE SYMPTOMS
Acute glaucoma can be painful. The sudden increase in pressure can make the eye red. Eyesight can deteriorate and may even blackout. There may be nausea and vomiting. Chronic glaucoma is less easily spotted. There is no pain and the deterioration in eyesight may be subtle. Some people go for an eye test after noticing their sight is less good in one eye than the other. The fact that this type of glaucoma can creep up on people is one reason why doctors advise regular eye tests.
HOW IS IT TREATED
Glaucoma is treated by reducing pressure on the eyes. Eye drops are a common first approach. However, if they fail to unblock the drainage channels then an operation may be needed. These can take the form of laser surgery or a trabeculectomy - an operation to improve drainage of the eyes.
CAN IT BE CURED
In many cases, the damage that has been caused by the glaucoma cannot be reversed. However, early diagnosis and treatment can prevent further deterioration.
