Don’t Let the “Silent Thief” of Sight Sneak up on You – Talk about Glaucoma this World Glaucoma Week and Protect Your Sight Before it’s Gone


Protect Your Sight Before it’s Gone
Last Updated: 23-Apr-2013

Glaucoma affects 67 million people worldwide1 and 2.2 million Americans,2 causing irreversible loss of vision if left untreated

Regular Eye Exams are Essential: Patients can lose up to 40% of their vision before realizing they have glaucoma3

Glaucoma is under-diagnosed: Early detection and proper treatment are necessary to preserve vision4

Approximately 67 million people around the world are living with glaucoma,1 and unfortunately, up to half of these sufferers aren’t aware they have the disease.5 In other words, more than 30 million people – which is more than the population of Australia – are slowly losing their sight without notice. Currently, there are 4.5 million people around the world who are blind from the disease.6

Glaucoma is the second-leading cause of preventable blindness worldwide,7 yet it is a disease that many know little about.5 Alcon, the world leader in providing treatment solutions for patients living with glaucoma, is raising awareness during World Glaucoma Week about the potential danger of this disease and the critical need for everyone to schedule regular eye examinations to protect their eyesight.

World Glaucoma Week: What Can You do to Help Preserve Your Vision?

Schedule an eye exam. Glaucoma is known as the “silent thief of sight”8 and is a disease without noticeable symptoms9 as much as 40 percent of your vision can be lost before you even begin to notice,3 so regular check-ups with an eye care professional are critical.4

Talk about glaucoma. Everyone, from babies to senior citizens, can develop glaucoma.10 Speak with parents, family, friends and colleagues about the disease and the importance of early detection.

Make sure your loved ones are taking their glaucoma medication. With adequate treatment, most people with glaucoma will not lose their sight.11 However, up to 25 percent of glaucoma patients do not take their prescribed medications.12 And, nearly 50 percent of patients stop taking their medication completely within six months of treatment,13 a behavior that, over time, could lead to vision loss.14

More About Glaucoma
Glaucoma is a group of progressive eye diseases that damage the optic nerve and typically occurs due to high pressure inside the eye (high intraocular pressure (IOP)).15 Because a healthy optic nerve is essential to the transmission of information from the eye to the brain,16 glaucoma can result in a gradual, irreversible loss of vision, and eventually blindness, if left untreated.17 The exact cause of glaucoma is unknown.

There are two main types of glaucoma: primary, or open-angle glaucoma, and acute, or angle-closure glaucoma. Open-angle glaucoma accounts for nearly 90 percent of all cases18 of glaucoma and is often asymptomatic, so symptoms often remain undetected until an advanced stage.19 It occurs when drainage from the anterior chamber of the eye occurs too slowly, causing IOP to increase.20 Angle-closure glaucoma, on the other hand, is less common, but can cause a sudden buildup of pressure in the eye,20 requiring immediate medical attention. Signs and symptoms of angle-closure glaucoma may include headaches, eye pain, nausea, rainbows around lights at night and blurred vision.11

Glaucoma Treatments and Risk Factors
Glaucoma is not curable21 and vision lost cannot be restored. However, remaining vision may be preserved through treatment.22 Glaucoma can be treated with eye drops, oral medications, laser surgery, traditional surgery, or a combination of these methods.23

In addition to high IOP,17 certain factors can increase the risk for developing glaucoma, including:24

People with a family history of glaucoma
Everyone over age 60
African-Americans over age 40
People of Asian descent (risk for angle-closure glaucoma, specifically)
People with diabetes, high blood pressure and heart disease
People with physical eye injuries
People who have used steroids for a long period of time.
