About Glaucoma

What Is Glaucoma?

Glaucoma is a progressive disease of the eye that if left untreated, can eventually lead to blindness. Glaucoma is commonly associated with increased pressure in the eye due to an imbalance in production and outflow of ocular fluid. In a healthy eye, fluid is produced to help maintain the eye’s shape. Normally, this natural fluid flows out through an area called the trabecular meshwork, and is absorbed into the bloodstream. If the fluid does not drain at the same rate that it is produced, pressure will begin to build in the eye. Over time, this increased pressure can damage the optic nerve and destroy vision.

Glaucoma is a common vision condition that affects millions of people around the world and can have
a significant impact on your quality of life.

If your doctor has recommended you undergo cataract surgery, you now have a once-in-a-lifetime
opportunity to treat your mild-to-moderate open-angle glaucoma at the same time as your cataract
surgery with the iStent inject.

Glaucoma is a progressive disease of the eye that, if left untreated, can cause vision impairments or
even blindness.

The most significant risk factor for the development and progression of open-angle glaucoma is
elevated pressure in the eye.

This increase in eye pressure, also known as intraocular pressure, occurs when the fluid in the eye
accumulates and cannot drain naturally.

High intraocular pressure can potentially lead to permanent vision loss.

Unfortunately, there is no cure for glaucoma. Most people take 1, 2, or even 3 medications daily to
control their glaucoma.

However, if you’re currently managing your glaucoma with medications and are now preparing for
cataract surgery, the iStent inject may be an ideal option for you.

FDA approved, iStent inject is the world’s smallest medical device known to be implanted in the
human body.

To help control the increased intraocular pressure associated with glaucoma, two tiny stents are
gently inserted in your eye during your cataract surgery. Once inserted, you will not be able to see or feel the device.

iStent inject works by creating two bypasses or openings inside the front part of your eye to its natural drainage pathway to restore your eye’s natural ability to drain fluid.

By lowering eye pressure, iStent inject may also reduce your need for glaucoma medications, but this
will be at the discretion of the eye care professional managing your glaucoma.

Worldwide, iStent inject is helping people with glaucoma successfully manage their intraocular

As with all procedures there can be risks associated with this device. Speak with your doctor to understand the important safety information or visit Glaukos.com.


Glaucoma & Eye Pressure

It’s easy to confuse eye pressure and glaucoma but important to understand the difference. Although intraocular pressure (IOP) is often associated with glaucoma, it’s possible to develop the disease without it. Whether you develop glaucoma depends on the level of pressure your optic nerve can tolerate without being damaged. This level varies from person to person, and in some cases, may never develop into glaucoma. That’s why it’s so important to schedule a comprehensive dilated eye exam at least once a year. It can help your eye care professional determine what level of eye pressure is appropriate for you.

Types of Glaucoma

There are two main types of glaucoma: open-angle glaucoma and angle-closure glaucoma.

Open-angle Glaucoma

The most common type of glaucoma, open-angle glaucoma, accounts for approximately 70% to 90% of all cases. The disease is progressive and has no detectable early signs. Elevated IOP is the most significant risk factor for the development and progression of open-angle glaucoma. As eye pressure builds, it gradually can lead to:

• Damage of the optic nerve
• Loss of peripheral vision
• Blindness, if left untreated

Angle-closure Glaucoma

The second most common type of glaucoma — angle-closure glaucoma — occurs when the drainage pathways in the eye become blocked by the iris. As a result, fluid cannot circulate through the eye and pressure increases. The condition can occur suddenly (acute angle-closure glaucoma) or gradually (chronic angle-closure glaucoma).

Your eye care professional can perform a simple eye test to determine if the angle in your eye is normal and wide or abnormal and narrow.
