- <p>Early detection will enable the President to control his
- glaucoma
- </p>
- <p> One of the best fringe benefits of being President is
- getting regular and thorough medical examinations. In George
- Bush's case, it could prove to be an eye saver. The White House
- announced last week that his latest checkup had revealed a
- budding case of glaucoma in his left eye, a disease that can be
- controlled if caught early, but can otherwise lead to blindness.
- Bush thus joins some 2.5 million other Americans who suffer from
- this common problem, and his case underscores the value of
- discovering glaucoma before serious damage is done.
- </p>
- <p> The President immediately began taking eyedrops to relieve
- his condition, and will continue to take them or some other kind
- of medication twice daily for the rest of his life. At 65, he
- has not lost any vision, and he is unlikely to have a serious
- loss of sight in the future. "I haven't felt a thing, felt it
- at all," said Bush, who was wearing sunglasses as he emerged
- from the checkup. The President, who passed all his other tests
- smartly, claimed that he felt "like a spring colt."
- </p>
- <p> Glaucoma occurs with increasing frequency in people over the
- age of 40, affecting 9% of those 70 or older. It is most common
- in blacks and those with a family history of the disorder. Of
- the three main types of the disease, Bush has by far the most
- common. His open-angle glaucoma can be treated painlessly and
- effectively, if found early enough. The more severe acute
- closed-angle glaucoma, on the other hand, causes sharp pain and
- visual impairment and requires prompt laser surgery. The third
- type, which blinded Ray Charles and Stevie Wonder, occurs at
- birth or soon thereafter.
- </p>
- <p> All forms result from accumulation of aqueous humor, a fluid
- that is generated behind the lens and then flows to the front
- of the eye, bringing nourishment and washing away waste
- products. In a normal eye, the humor drains as it is produced,
- maintaining a constant ebb and flow. But in those with glaucoma,
- the drainage canals are somehow blocked, leading to an increase
- in pressure. "Glaucoma is a plumbing problem," says H. Dunbar
- Hoskins of the San Francisco-based Foundation for Glaucoma
- Research. If left untreated, the pressure eventually harms the
- optic nerve. The reason for the buildup is not known.
- </p>
- <p> Early treatment of open-angle glaucoma with eyedrop drugs
- like levobunolol hydrochloride, which Bush is taking, slows
- production of the aqueous humor and relieves the pressure.
- Eventually, however, many patients develop a tolerance for the
- drugs and must switch medications. Occasionally, surgery is
- needed, though in Bush's case probably not for many years. This
- glaucoma is easy to overlook, since it has no overt symptoms.
- But doctors are becoming more vigilant, and the American
- Academy of Ophthalmology now recommends that everyone over 40
- be tested every two years.
- </p>
- <p> In all other respects, Bush's health is "truly excellent,"
- said White House physician Burton Lee. And the President's
- vision, it seems, is more likely to be a serious concern for his
- political critics than for his doctors.
