Neuroprotection: Help for the Glaucoma Patient?

People with glaucoma do not always retain their vision. In some cases this is because the glaucoma is far-advanced before it is detected. Other people do not care for themselves properly and their glaucoma consequently gets worse. Still others are not cared for appropriately by their physicians and their glaucoma gets worse. But somewhere around one third of all those with the commonest type of glaucoma, idiopathic open-angle glaucoma, get worse even when they are under the care of skilled ...

Cataract Surgery and the Glaucoma Patient

By Jeffrey Henderer, MD

Cataract is a clouding of the eye’s lens that typically occurs as part of the normal aging process. Since modern cataract surgery, in which the lens is removed and replaced with a clear plastic one, is usually quite safe and effective, deciding if and when to do so in otherwise normal eyes is usually fairly straightforward. If blurred images and glare caused by a cataract prevent a person from doing what he or she needs or likes ...

Now That I Have Glaucoma What Can I Expect

By George L. Spaeth

“Now that I’ve been told I have glaucoma, what can I expect? ” This question has to enter the mind of every person who has just learned that he or she has glaucoma. It may be a sufficiently frightening question that the person never speaks it aloud. But it’s the sort of question that most physicians dread, because it asks for projections that are extremely difficult to make. It asks the ophthalmologist to “play God,” and, while ...

Understanding the Role of Blood Flow in Glaucoma

By George L. Spaeth

All physicians, including glaucoma specialists, seek to discover the fundamental causes of an individual’s disease. For it is only when those causes have been identified that the most appropriate treatment can begin.

Persons with glaucoma have suffered some kind of tissue damage, frequently to the optic nerve. But knowing that the cause of glaucoma is optic nerve damage does not provide the physician nearly enough information. To initiate effective therapy requires knowing the reason for the tissue damage, ...

How Does Lifestyle Affect Glaucoma

By George L. Spaeth

Once a person has glaucoma, his or her eyes are predisposed to more damage. Anything causing the eyes not to get the nutrients they need will increase the damage. Thus, marked malnutrition, such as the thiamin deficiency common in some parts of the world, damages tissues such as the optic nerve. Other forms of malnutrition (protein deficiency, other vitamin deficiencies, etc.) can also be damaging.
Obesity

At the other extreme, obesity also can predispose to damage and is ...

Common Misconceptions of Glaucoma

By George L. Spaeth

One of the reasons so many patients with glaucoma get worse is that they have serious misunderstandings and misconceptions about it. Here are some of the more common ones.

It is a misconception that patients with glaucoma lose peripheral vision. “Peripheral vision” for most people means vision off to the side. That is, when a person is looking straight ahead, peripheral vision means vision way off to the right side and way off to the left side. But ...

Diagnosis of Glaucoma

By George L. Spaeth

Both patients and doctors tend to underestimate the value of diagnosis. Foremost in their minds is getting and providing effective treatment. In fact, however, the key to effective treatment of glaucoma or any disease lies in an accurate diagnosis.

“Diagnosis” sounds simple and, indeed, the meaning of the word is simple. Diagnosis means putting a descriptive label on a problem so that appropriate measures can be taken to solve it.

Unfortunately, putting the label “glaucoma” on a set of ...

Understanding Glaucoma

Every year, millions of people world-wide go blind from glaucoma. Just what is this disease, and what can be done about it?

Glaucoma is a group of conditions in which the optic nerve cells in the back of the eye have died at least partly due to pressure inside the eye (intraocular pressure) exerted by the fluid in the eye (aqueous humor) which is too high for the nerve cells in that particular eye to tolerate. The optic nerve cells’ job ...
