Eye Drops Delay Onset Of Glaucoma In People At Higher Risk

BETHESDA, MD — June 14, 2002 —

 Researchers have discovered that eye drops used to treat elevated pressure inside the eye can be effective in delaying the onset of glaucoma. These results mean that treating people at higher risk for developing glaucoma may delay — and possibly prevent — the disease.

 These findings are reported in the June 2002 issue of Archives of Ophthalmology. Scientists found that pressure-lowering eye drops reduced by more than 50 percent the development of primary open-angle glaucoma, the most common form of glaucoma and one of the nation’s leading causes of vision loss.

 Researchers noted that 4.4 percent of the study participants who received the eye drops developed glaucoma within five years. By comparison, 9.5 percent of the study participants who did “not” receive the eye drops developed glaucoma. Additionally, several significant risk factors were found to be associated with the development of glaucoma in study participants. These included personal risk factors, such as older age and African descent, as well as ocular risk factors, such as higher eye pressure, certain characteristics in the anatomy of the optic nerve, and thinness of the cornea
