"Retinopathy and optic nerve pathology are frequent early clinical signs of MS but also occur with acute raised intrathoracic pressure as blood is forced back into the head producing surges of intracranial venous pressure (‘Valsalva retinopathy’)[4–13]. Apart from such acute events, chronic venous hypertension may result from arteriovenous anastomoses (AVA), in particular dural arteriovenous ?stulas (DAVFs), within the head [14,15] or spine [16]. Borden et al. [17]" David Talbert, London Note this paper preceded Zamboni's CCSVI paper! http://www.direct-ms.org/sites/default/files/Talbert%20Venous%20pressure%20MS%2008.pdf
