Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...
