The Neurosurgeon's Role in Acute Visual Failure

Anterior visual pathway cavernous malformations

“…Twenty-five additional articles were identified and included through hand-searching bibliographies and citations. Thus, a total of 60 articles with 70 reported patients (including the current illustrative patient) with CM affecting the anterior visual pathway were included (Table 1) [7,.…”

Optochiasmatic Cavernous Angioma with Rapid Progression after Biopsy Despite Radiation Therapy

“…The CA remnant must be considered to have a risk of symptomatic bleeding, and some patients, especially those with good visual outcomes, will merit further treatment of the remnant 2) . One of the case studies reviewed had good results with postoperative radiotherapy, without long-term recurrence 15) . While stereotactic radiotherapy has been used to treat CAs throughout the brain with good results 2) , there are recognized tolerance limits of the anterior visual pathway beyond which the risks of optic neuropathy increase unacceptably 7) .…”

Cavernous Malformation of the Optic Chiasm with Multiples Cerebral Cavernous Malformations

“…The annual bleeding risk of cavernomas is 0.6%/ year and 4.5%/ year of re-bleeding [5]. The functional impotence of this region explains the presence of clinical signs at the slightest bleeding.…”
