| Full Abstract: |
Dr. Markoff's concern that the supine nature of trumpet playing used in the study, Increased Intraocular Pressure and Visual Field Defects in High Resistance Wind Instrument Players, compromised the results is unfounded as the study indicates measurements taken in both the sitting and supine positions. The ultrasound biomicroscopy used to study the uveal thickness required the use of the supine position. No differences in the measurements were found between the two playing positions, including playing in the high register playing and at loud volumes. Furthermore, studies are found that both support and dissent the use of the Valsalva maneuver in wind instrument playing. Additionally, the physical structure of the instruments and manifestation of wind resistance was beyond the scope of this study. |
