Rises in IOP measured after musicians play a wind instrument and during some of their other daily activities may have implications for glaucom risk, new research shows, according to a report in Medscape. "This might be relevant for their risk of visual field progression," Dr. Ronald de Crom of Maastricht University Medical Center in the Netherlands, the new study's first author, told Reuters Health by email. "In case of a significant IOP rise, (glaucoma) treatment can be intensified to promote a more stable diurnal curve."
IOP is a key risk factor for glaucoma, and a handful of studies have found increases in pressure within the eye among musicians who play wind instruments, Dr. de Crom and his team note in their report, published August 22 in the Journal of Glaucoma. One study found that those who played high-resistance wind instruments were more likely to have visual field loss than other musicians, with the risk increasing the greater the number of hours the musician had played in his or her lifetime.
In the new study, the researchers measured IOP in 11 professional and 31 amateur musicians (9 with glaucoma) before and after they played a wind instrument for 20 minutes.
