Retinal venous pressure is higher than the airway pressure and the intraocular pressure during the Valsalva manoeuvre.

During the VM, the RVP was increased compared with the ∆AirP.

The retinal venous pressure at different levels of airway pressure measured with a new method.

An increase in AirP was accompanied by a linear increase in RVP.

Measurement of the retinal venous pressure with a new instrument in patients with primary open angle glaucoma.

In both methods, the range of the single measurements may be taken as a sign of good reliability, the CCC of 0.96 as a sign of a very good agreement.
