• Wakerlin and his associates have reported' 2 that chronic bilateral carotid sinus compression in dogs resulted in a sustained elevation of the mean arterial pressure. This finding was confirmed by Hawthorne and Gaspar, who reported also that the elevated mean arterial pressure after bilateral carotid sinus compression was ameliorated by hypophysectomy. Kezdi reported that bilateral constricti...

The gross anatomy of the optic nerves and chiasma has been studied, and differences in the tension in the crossed and uncrossed fibres after chiasmal displacement have been investigated. The anterior and posterior attachments of the medial and lateral fibres of the nerves have been studied. The chiasma has been dissected under low power microscopy and a three dimensional picture of it developed...

We read with great interest the paper by McCoy et al. validating the neurological hemifield test (NHT) to detect and classify visual field loss caused by chiasmal or postchiasmal lesions. In this paper, more than 60% of glaucoma eyes misclassified as neurological according to the NHT score criterion had binasal defects. Therefore, interpreting binasal hemianopia is a particular challenge. To em...

Carotid and vertebral artery dissection are relatively frequent and risky conditions. In the last decade, different patients with extracranial (and in 1 case also intracranial) dissections associated with the practice of scuba diving were reported. The connection between the two conditions has not been fully explained so far. In the present article, we report the case of a patient presenting wi...

Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the...
