Abstract

Variations in intra-ocular pressure (IOP) were demonstrated before, during and after extracorporeal circulation in pigs. Most probably both the observed increase and reduction in IOP may be explained by corresponding changes in blood osmolality, blood pressure and body temperature. In contrast to clinical findings, no increase in IOP was observed during the period of extracorporeal circulation.
