barometric pressure

As mentioned I will discuss pressure today. I have a mechanical engineering background and process pressures is one of the parameters I work with every day.

The intraocular pressure of an eye, IOP, is measured in mmHg which stands for millimetre Mercury column. In the old days barometers were U shaped glass tubes filled with Mercury and the height of the Mercury indicated barometric pressure.
