Spontaneous venous pulsations (Video)
This video shows what spontaneous venous pulsations look like in the retina. This eye is suffering from ocular ischemic syndrome which has dilated the retinal veins and make them even easier to see than usual.
Most people believe that these pulsations are caused because of a differential between eye and CSF pressure. The CSF cavity (transmitted forward along the optic nerves) is separated from the vitreous cavity by only the lamina cribosa at the optic nerve head. When pressure is elevated too high around the brain, the pulsations stop because the pressure gradient is too high. The presence of pulsations is a reasonably good indicator that the CSF pressure is ok. Unfortunately, the lack of pulsations doesn’t tell you much as this can be entirely normal.
Pulsations are only rarely examined in ophthalmology, and this findings is more often sought after by neurology who deal more with ICP issues.

Hi,
Thanks for the interesting video. I can see the veins dilated, which is a classical sign of OIS. The arteries look much attenuated and these pulsations seem to originate rather from the retinal artery, which is another typical sign of severe ocular blood flow compromise.

Hi,

thx you very much!
Im from Vietnam, where don’t have many video for study.
This Web Help me very much. THx agan .
Great video, thank you so much. Being in my last year of neurology, I have always had difficulty seeing this, but now I have a better idea of what to look for.

This is a very interesting video about venous pulsations, Thank you very much Tim Root.
very nice videos, thank you very much
it is really a good vidio for newcommers in opphthal society THANKS
2times I saw spontaneous venous pulsations when taking fundus examination in patients. This sign also broughtsome questions to me and I tried to explain it
this is v unfortunate that i cant see d videos 🙁
pls help….m v much interested…
just superb
its just a wonderful video such as others in this useful website.. thnx
Awesome. thanks
Do you know what kind of equipment can record the video?
Any free database for such a video?
Thanks
Dude, you’re awesome!
Thank u for the video! I have p.t.c. and my neurologist is always asking me to ask my eye Dr to check the v.p in my eyes!
Dr Root is a masterful teacher. He makes otherwise difficult and esoteric points and topics very easy to understand. His efforts to produce these educational videos at such high quality, are helping doctors and people all over the world. Brilliant eye doctor and a GREAT and generous person! 👍👏
