Translated abstract:
While playing wind instruments a Valsalva-like manoeuvre is performed, during which the intraocular pressure (IOP) increases. IOP was assessed by rebound tonometry in a sitting position while playing 32 high and low resistance wind instruments. The measurements were obtained during normal and laborious playing intervals, as well as after cessation. The highest increase of IOP of 9,2 mmHg (p<0,001) could be observed during laborious high resistance wind instrument playing. Additionally a negative correlation, regarding the level of the IOP rising and its relative decrease towards initial value after performance, was detected. IOP changes, especially found during laborious playing with high resistance wind instruments, could be a risk factor for glaucomatous optic nerve damage.
