Research conducted by UC Davis ophthalmology professor James Brandt and 21 other leading clinical centers in the United States shows that eye drops used to treat elevated pressure inside the eye can be effective in delaying the onset of glaucoma. These results mean that people at higher risk for developing glaucoma may delay – and possibly prevent – the disease by using prescribed drops.
Elevated eye pressure occurs when fluid that flows in and out of the eye drains too slowly. It is estimated that between 3 million and 6 million people in the United States – including between 4 and 7 percent of the population older than 40 – have elevated eye pressure and are at increased risk for developing open-angle glaucoma. Until now, doctors did not know if treating elevated eye pressure before glaucoma developed could delay the onset of the disease.
