Purpose: The purpose of this study was to examine the impact of the Mozart effect on the reliability of the Humphrey visual field (HVF; Carl Zeiss Meditec, Dublin, CA) test in subjects with glaucoma. A previous study showed improved reliability in normal subjects undergoing HVF testing.
Methods: One hundred sixty subjects with glaucoma were randomized to three groups: control, headphones, or music for 10 minutes before HVF testing. The headphone group was provided noise-cancellation headphones but no music. The music group listened to Mozart's Sonata for Two Pianos in D Major. After treatment, subjects took an HVF test in both eyes. The reliability of the test was then compared between the groups and also to prior HVF results with regard to fixation losses, false positives, and false negatives.
Results: The rate of fixation losses did not differ significantly between the three groups (P = 0.30 right eye, P = 0.24 left eye). There were also no significant differences in the rate of false positives (P = 0.82 right eye, P = 0.18 left eye) or false negatives (P = 0.91 right eye, P = 0.97 left eye). The reliability of the subject's HVF result was also compared with past field results. No improvements were seen in fixation losses (P = 0.94 right eye, P = 0.17 left eye), false positives (P = 0.85 right eye, P = 0.38 left eye), and false negatives (P = 0.13 right eye, P = 0.50 left eye).
Conclusions: The rate of fixation losses, false positives, and false negatives did not improve in subjects with glaucoma after they listened to Mozart's music. The Mozart effect did not enhance the reliability of the visual field test to a statistically significant degree (ClinicalTrials.gov number, NCT01027039).
