- QUESTION: I don't know how to take the reporting about President Bush's
- glaucoma. Are they playing it down, so that people won't get worried about
- the ability of the President to function? Doesn't this disease lead to
- blindness? Perhaps you might want to explain this condition to your readers,
- so they will know what is happening in the White House.

- ANSWER: I am not sure that I am the one to comment on events in the White
- House, they are confusing to me as well. But one thing is for sure.
- President Bush is putting in his eye drops just as the doctor ordered.
- Therefore it is highly unlikely that he will lose any of his vision, or be
- unable to carry out his responsibilities. Glaucoma is a disorder
- characterized by an increase of pressure within the eyeball. The eye produces
- a fluid (aqueous humor) which circulates through the globe of the eye before
- leaving through exit canals near the base of the iris. If either too much
- fluid is produced or there is a blockage of the outflow passages, the tension
- or pressure within the eyeball increases. This pressure pushes against the
- optic nerve, damaging it and causing a very gradual loss of vision. Blindness
- may occur, but only in those individuals where the diagnosis is late and
- treatment has not been carefully carried out. The progress of the condition
- is evaluated using an instrument called a tonometer, which can accurately
- measure the intraocular tension (pressure within the eye). Since the iris may
- push against the canals which carry the fluid away from the eye when they are
- dilated or widely opened, the drops carry a medication which keep the iris
- closed (called "miotics"). Many such medications are available; pilocarpine,
- timolol and betataxolol to name a few. For the greater majority of patients
- with this condition, the drops will be enough to control the disease and
- prevent serious damage of the vision. The President will have to restrict his
- liquid intake, avoid tobacco (I don't think he smokes) and, according to the
- textbooks, avoid fatigue and stress (don't ask me how he will manage that!).
- Should his therapy with eye drop medicine fail, there are surgical techniques
- called iridectomy or laser iridotomy that can be used to relieve the pressure
- by removing a bit of the iris that pushes against the outflow canals.
