Like blood pressure, the pressure of fluid in the eyeball can fluctuate during the day. And the more it does, the higher the risk that a glaucoma patient will lose vision.

Thatís the bottom line of recent work from Johns Hopkins, where ophthalmologists studied 64 people with glaucoma. Itís been known that the disease causes pressure to rise in the eye. Most treatments and medications focus on lowering that. But the link between frequent pressure fluctuation and ultimate loss of sight wasnít clearly shown until now. Dr. Ran Zeimer of the Hopkins Wilmer Eye Institute.

I donít think anybody expected that it would have such a high risk factor. And therefore, I think weíre opening a new era where people will focus on research and on drugs that could specifically benefit the lowering of the fluctuation. :15

In other words, says Dr. Zeimer proper treatment of glaucoma now takes on a new challenge. Lowering pressure isnít enough, the goal must include controlling dips and rises in eye pressure.
