Transcript of Eye Conditions

What is it?
The two most common forms are primary open-angle glaucoma (POAG) and angle-closure glaucoma (ACG). Open-angle glaucoma is often called "the sneak thief of sight" because it has no symptoms until significant vision loss has occurred.
Glaucoma is a complicated disease in which damage to the optic nerve leads to progressive, irreversible vision loss. Glaucoma is the second leading cause of blindness.
A variety of options are available to treat glaucoma. These include eye drops, laser procedures, and surgery. All are intended to decrease eye pressure and, thereby, protect the optic nerve.
What Causes It?
Elevated eye pressure is due to a buildup of a fluid that flows throughout the eye. Normally, the fluid drains into the front of the eye through tissue at the angle where the iris & cornea meet. When fluid is overproduced or doesn't drain properly, the fluid can't flow out at its regular rate & pressure builds up.

"Open-Angle" means that the angle where the iris meets the cornea is as wide & open as it should be. Open- Angle glaucoma is also called primary or chronic Glaucoma. It is tho most common type of Glaucoma.
Also called low - tension or normal- pressure Glaucoma. The optic nerve is damaged even though the eye pressure is not very high
It is also called acute Glaucoma or narrow- angle Glaucoma. Unlike Open- Angle Glaucoma, Angle- Closure Glaucoma is a result of the angle between the iris & cornea closing.
Angle - Closure Glaucoma
The ancient Greeks coined the term Glaucoma, which they used to describe all eye diseases that led to blindness. In the first several centuries A.D., cataracts, which can be treated, started to be distinguished from Glaucoma, which couldn't be amended.
There are typically no early warning signs or symptoms of open-angle glaucoma. It develops slowly and sometimes without noticeable sight loss for many years.
Hazy or blurred vision
the appearance of rainbow-colored circles around bright lights
severe eye and heap pain
nausea or vomitting (along with eye pain)
sudden sight loss
Myth: glaucoma only affects the elderly. Fact: While it is true that the risk of having glaucoma increases as we get older, and that the majority of open-angle glaucoma is age-related, this eye disease can affect people of all ages, even newborns.
Myth: glaucoma only occurs if you have elevated eye pressure. Fact: While it is true that elevated eye pressure is a major risk factor (and can be causative) of glaucoma, some people with elevated eye pressure do not develop this eye disease. It is also possible to have severe glaucoma with so-called “normal” eye pressures.
Myth: Glaucoma is inherited, and since no one in my family has it, then i wont get the disease. Fact: While it is true that certain forms of glaucoma are inherited, and that a family history of glaucoma is a risk factor, there are many glaucoma patients who are the only ones in their families who are diagnosed with this eye disease.
Open - Angle Glaucoma
Normal - Tension Glaucoma
Congenital Glaucoma
Occurs in babies when there is incorrect or incomplete development of the eye's drainage canals during the prenatal period. This is a rare condition that may be inherited.
Glaucoma is the result of damage to the optic nerve. As the nerve deteriorates, blind spots develop in your visual field for unknown reasons, this nerve damage is usually related to increased pressure in the eye.
Who's Affected?
It's estimated that over 3 million Americans have Glaucoma but only half of those know they have it
In the U.S. over 120,000 are blind from Glaucoma, 9% to 12% of all cases of blindness
After Cataracts, Glaucoma is the leading cause of blindness among African Americans
Blindness from Glaucoma is 6-8 times more common in African Americans than Caucasians
Estimates put the total number of suspected cases of Glaucoma at over 60 million worldwide
Open - Angle Glaucoma: Proper treament greatly reduces the risk of vision loss in persons with chronic Glaucoma. However, if chronic Glaucoma remains untreated, permanent blindess can occur.

Acute - Glaucoma: If an episode of acute Glaucoma is treated early, vision in the affected eye may return to a 'level' that is almost the same as what it was before the episode began. If acute Glaucoma is neglected, you can be blind in the affected eye in two days or less.
Anybody is at risk for contracting glaucoma, but certain factors make these people at a higher risk for developing the disease.
people over 40: it occurs more frequently as people age.
People who have a family history of glaucoma: The tendency for developing glaucoma may be inherited.
people of African, Latino, and Asian descent: People with African and Latino ancestry have a greater tendency for developing primary open-angle glaucoma than do people of other races. People of Asian descent are more prone to develop angle-closure glaucoma and normal-tension glaucoma.
We intend to use this information to educate my peers on the facts about Glaucoma. It is a common eye condition that we should all be aware of. This information can help some people who may believe they have Glaucoma, determine whether or not hey may have this condition. Especially since everyone is able to be affected by this condition.
