Explain about the Ocular Haemodynamics.

The pressure in the ocular arteries can be measured by optical ophthalmodynamometer. The intraocular pressure is raised to the level that stops the diastolic blood [low and then the level which stops the systolic pressure. The values are recorded with the help of direct visualization of retinal vasculature. The human eye pressure is lower than the rest of the body's blood pressure. The mean arterial pressure of ophthalmic artery is 77 mmHg whereas the mean arterial pressure of brachial artery is 100 mmHg. The pressure inside the intraocular veins is equal to the intraocular pressure at the site where these veins pierce the sclera. So the pulsation of retinal veins at optic disc indicate that the pressure inside them is above the intraocular pressure.
