Men with erectile dysfunction (ED) are almost three times more likely to have been previously diagnosed with glaucoma, according to a study published in Ophthalmology (2012;119:289-293).

The researchers found that 1.1% of men with ED had been diagnosed with glaucoma compared with only 0.4% of control subjects. After adjusting for potential confounders, men with ED had a 2.85 times increased likelihood of having a prior glaucoma diagnosis compared with men who did not have ED.
