Spontaneous Venous Pulsation

Spontaneous Venous Pulsation
Spontaneous venous pulsations are a common occurrence in normal eyes (75 %). Retinal veins pulsate because there is a momentary imbalance between the pressure on the outside of the wall that overcomes momentarily the rigidity of the wall and the internal pressure of the vein.The venous pulsations vary from individual to individual and in certain individuals the venous pulsations may be quite difficult to see. When the pulsations are present, it probably means that CSF pressure is normal. When the pulsations are absent, however, the information is less valuable, because so many normal individuals do not have them or they are difficult to see. Pulsations become obvious in patients with wide ranges between systolic and diastolic pressures. The video clip shows prominent pulsations in a patient with anemia who also shows intraretinal hemorrhages.
