Strategies to Help Prevent Hypertension: ome Blood Pressure Drugs Raise Risk of Blindness

Some Blood Pressure Drugs Raise Risk of Blindness

Another major population study discovered that some type of hypertension drugs called vasodilators actually increase your risk of early onset of age-related macular degeneration (AMD), which is the most common cause of blindness among American seniors. As noted in a press release:17

"...[R]esearchers... conducted a long-term population-based cohort study from 1988 to 2013 of nearly 5,000 residents of Beaver Dam, Wis., aged 43 to 86 years... The researchers found that, after adjusting for age, sex and other factors, using any vasodilator such as Apresoline and Loniten, which open (dilate) the blood vessels—was associated with a 72 percent greater risk of developing early-stage AMD. Among people who were not taking vasodilators, an estimated 8.2 percent developed signs of early AMD. In comparison, among those taking a vasodilator medication, 19.1 percent developed the disease.

The researchers also found that taking oral beta blockers such as Tenormin and Lopressor was associated with a 71 percent increase in the risk of neovascular AMD, a more advanced and vision-threatening form of the disease. Among those who were not taking oral beta blockers an estimated 0.5 percent developed signs of neovascular AMD. In comparison among those taking oral beta blockers, 1.2 percent developed neovascular AMD."
