“A blue light from the head of the tonometer is then held against the eye to measure pressure in the eye.”

“Sometimes the tonometer is placed directly against the eyeball and pressure is applied in order for a reading to be taken.”

“The value of the IOP is derived from the amount of pressure it takes for the tonometer to flatten the cornea.”

“In the first set of experiments, the target blood pO 2 levels 40, 80, 160, and 400 torr were reached by tonometry.”

“However, enteral feeding is withheld during monitoring with gastric tonometry because enteral feeding is thought to influence tonometric measurements.”

“To compare dynamic contour tonometry as a new method for intraocular pressure measurement with Goldmann applanation tonometry.”
