From the BCSC 2019-20: "Absence of spontaneous venous pulsations may reflect increased ICP, but absence at initial examination is of limited value; 20% of the general population have no spontaneous venous pulsations. The disappearance of these pulsations after prior documented presence, however, suggests ICP elevation."

Very interesting!

What about induced svp by indenting the bulbus when svp Is absent
