title: Eye signs in 611 cases of posterior fossa aneurysms: their diagnostic and prognostic value.
abstract: This review of 611 cases of aneurysms in the posterior fossa managed by one neurosurgeon between 1965 and 1980 shows that eye signs are important indications for investigation and may lead to earlier detection and treatment of the aneurysm. They were present in 50% of the patients. Major defects in ocular motility or the visual field were present preoperatively in 57 of the 64 patients with unfavourable surgical results--postoperative death or total physical dependency. Of the same 64 patients 55% (35) had "giant" aneurysms, as compared with 17% (102) of the entire group of patients. Hypertension was present in 50% of the patients who died and 25% of those with poor functional results after surgery. Computer-assisted tomography and four-vessel angiography are essential for accurate localization of the aneurysm and for blood-flow information important in determining the best surgical approach.
