Mozart and peripheral vision
Subjects who underwent automated perimetry testing for the first time appeared to have improved test performance results after listening to Mozart, a Brazilian study asserts.
Vanessa Macedo Batista Fiorelli, MD, and colleagues compared the results of automated perimetry on 60 normal subjects who listened to the first 10 minutes of a Mozart sonata and 30 normal subjects who did not listen to the sonata. All subjects underwent a complete ophthalmic exam. Those with refraction beyond + 5 D or –5 D, best corrected visual acuity of less than 20/20, IOP over 21 mm Hg and cup-to-disc ratio greater than 0.5 were excluded.
Those in the Mozart group had “significantly less fixation loss, false positive and false negative rates compared with the controls,” the authors said. However, they warned the study “does not prove that the Mozart sonata was the causative factor for the improved performance.”
The study is published in British Journal of Ophthalmology.
