January 2010 is National Glaucoma Awareness Month, Learn How to Help Aging Family Members Who Have This Disease

By , January 13, 2010

When an aging family member starts to have problems with their vision, many times that loss can be attributed to glaucoma. It’s important for seniors and their family members to understand the causes and treatments for glaucoma so that the affected senior can live independently for as long as possible.

Glaucoma is an eye disease that causes loss of sight by damaging a part of the eye called the optic nerve. This nerve sends information from your eyes to your brain. When glaucoma damages your optic nerve, you begin to lose patches of vision, usually side vision (peripheral vision). Over time, glaucoma may also damage straight ahead (central) vision. You may not notice a loss of side vision until you have lost a great deal of your sight. When checking for glaucoma, eye doctors usually look for damage to the optic nerve and any loss of side vision. They may also check your eye pressure.

Glaucoma is often called “the sneak thief of sight.” That’s because people usually do not notice any signs of the disease until they have already lost significant vision. Once lost, vision can’t be restored.

More than 2.2 million Americans age 40 and older have open angle glaucoma, the most common form of glaucoma. At least half don’t even know they have it.

What are the Different Types of Glaucoma?

There are many types of glaucoma. Often, the cause of high pressure in the eye can help tell the type of glaucoma and the best treatment for it. The most common types include:

Chronic (Open Angle) Glaucoma
This is the most common type. In open angle glaucoma, aqueous fluid drains too slowly and pressure inside the eye builds up. It usually results from aging of the drainage channel, which doesn’t work as well over time. However, younger people can also get this type of glaucoma.

Normal Tension Glaucoma
This is a form of open angle glaucoma not related to high pressure. People with normal tension glaucoma may be unusually sensitive to normal levels of pressure. Reduced blood supply to the optic nerve may also play a role in normal tension glaucoma.

Acute (Angle Closure) Glaucoma
Less than 10 percent of Caucasians or African-Americans have this form, but for those of Asian and Native American descent, the risks are as high as for open angle glaucoma. Hispanics are midway between these groups. It causes a sudden rise in pressure, requiring immediate, emergency medical care. The signs are usually serious and may include blurred vision, severe headaches, eye pain, nausea, vomiting or seeing rainbow-like halos around lights. Occasionally, the condition may be without symptoms; similar to open angle.

Secondary Glaucoma
Another 10 percent of glaucoma cases come from certain diseases and conditions that damage the eye’s drainage system. These include diabetes, leukemia, sickle-cell anemia, some forms of arthritis, cataracts, eye injuries or inflammation of the eye, steroid drug use and growth of unhealthy blood vessels.

Post-Surgical Glaucoma
Some surgeries, such as retinal reattachments, increase the chance of getting glaucoma.

Getting more involved in your treatment
Even if surgery or drugs lower pressure in your eye, it’s still possible to lose vision. Therefore, you and your doctor must carefully monitor the disease.
Since you will be visiting your eye doctor regularly, take time and care in choosing a person who you are comfortable with. Your doctor should understand that your questions and concerns are important. A doctor who is willing to work with you, listen to your concerns and provide the best treatment, plays a large part in your success against glaucoma.

You have to help save your sight
You may need medicines every day for the rest of your life. Find support and encouragement from your family, friends and others. Sometimes it helps to talk to people who have experienced the same thing. It can help you to discuss side effects, share ways to remember your medicines and celebrate getting your glaucoma under control.

Unfortunately, there are a few people whose eyesight will continue to get worse, despite doing all the right things to control their glaucoma. Doctors aren’t sure why this happens, but research in this area continues.

The future holds great promise for treating glaucoma. New medicines are being developed. Other treatments may soon become available. In the meantime, take heart in knowing that you’re doing everything possible to treat your glaucoma successfully. The doctor/patient team approach, support from others and promising scientific discoveries will help you look forward to a bright future.

Questions for your eye doctor

You will have many questions as your doctor diagnoses and treats your glaucoma. It’s helpful to keep a list of these questions, especially if they come to mind in between your eye appointments. Write all your questions down and bring the list with you, then discuss them with your doctor. Here are some questions many people have:

•    What do these medicines do?
•    How much will they cost? Will my insurance help pay for them? (These may be questions for your insurance company, not your doctor.)
•    What are the possible side effects of my medicines?
•    Can I do anything to lower the chance of side effects or reduce the effects?
•    What should I do if I miss a dose?
•    Will I need surgery? What are the benefits and drawbacks of laser surgery? Of glaucoma surgery?
•    What will my vision be like after surgery?
•    How long will recovery take? How will I need to change my usual activities?
•    Will I be able to drive? Go to work?
