Intra-ocular pressure during and after playing high and low resistance wind instruments
Kappmeyer K; Lanzl IMOphthalmologe 2010; 107: 41-46
Background: A Valsalva maneuver was performed while playing wind instruments during which the intraocular pressure (IOP) increased. Methods: IOP was assessed by a rebound tonometer while playing 32 high and low resistance wind instruments in a sitting position. The measurements were obtained during normal and laboured playing sequences as well as after cessation. Results: The highest increase in IOP of 9.2 mmHg (p<0.001) could be observed during laboured playing of high resistance wind instruments. Additionally a negative correlation was detected between the level of the IOP increase and the relative decrease towards the initial value after performance. Conclusion: IOP changes found in particular during laboured playing with high resistance wind instruments could be a risk factor for glaucomatous optic nerve damage. LA: German
