英文摘要: Abstract(#br) Background(#br)To evaluate the effect of the Valsalva maneuver (VM) on short-term variations of intraocular pressure (IOP) and ocular pulse amplitude (OPA) values in healthy, young, male subjects.(#br) Methods(#br)IOP and OPA values were measured before and during VM by Pascal dynamic contour tonometer (DCT) in 55 eyes of 55 healthy male volunteers aged 20 through 27 years.(#br) Results(#br)Mean IOP before VM was 17.2 ± 2.9 mmHg and during the VM was 19.8 ± 4 mmHg. The increase in mean IOP during the VM was found to be statistically significant ( p = 0.001). The IOP increased in 46 (83.6%) of 55 eyes. However, in nine eyes (16.4%), IOP decreased during the VM. Mean OPA value before VM was 3.6 ± 1.4 mmHg and during the VM was 3.6 ± 1.3 mmHg. The change in mean OPA value was...
