Optic nerve headVenous pulsation amplitudes and surrounding retinal tissue characteristics were quantified using photoplethysmography and OCT.Larger diameter veins and venous pulsations occurring closer to the optic cup margin have higher pulsation amplitude.The presence of a proximal arteriovenous crossing, ...
(hypoglossal venous plexus of Trolard) and intracranially connects with the clival dural and the inferior petro-occipital vein of Trolard.37Harrigan and Deveikis43theorized that the venous plexus of Rektorzik might dampen thearterial pulsationsof the ICA along its course within thepetrous bone, ...
Treatments of the sequelae of the venous thrombus are numerous as venous thrombi lead to many complications. For patients with chronically elevated intracranial pressure (ICP), the ICP can be medically lowered with acetazolamide or CSF diversion with ventriculoperitoneal shunts or optic nerve sheath f...
The presence or absence of spontaneous retinal venous pulsations (SVP) provides clinically significant insight into the hemodynamic status of the optic nerve head. Reduced SVP amplitudes have been linked to increased intracranial pressure and glaucoma progression. Currently, monitoring for the presence or...

]. In chronic untreated cases, optic disc edema can be followed by optic atrophy due to damage to the retinal ganglion cells. Optic nerve pallor suggests that permanent injury to the optic nerve has occurred. The presence of spontaneous venous pulsations has been considered to exclude the ...
