Increasing interest in the field of cerebrovascular disease has resulted in a demand for diagnostic procedures free from risk which can be used for screening purposes to decide which cases should be further investigated. Thermography, which combines a high degree of accuracy with complete safety, meets the need. The first reports of the value of this method (Wood, 1965; Wood, Hill, and Heyman, ...

PURPOSE To identify the α(1)-adrenoceptor (α(1)-AR) subtypes mediating vascular adrenergic responses in murine ophthalmic arteries. METHODS Expression of mRNA was quantified for individual α(1)-AR subtypes in murine ophthalmic arteries using real-time PCR. To assess the functional relevance of α(1)-ARs for mediating vascular responses, ophthalmic arteries from mice deficient in one of the thr...

A 64-year-old man complaining of pulsatile headache was admitted. Imaging studies revealed a near-total occlusion of the right proximal internal carotid artery (ICA) with slow antegrade flow into the distal ICA. Right cerebral flow was supplied by collateral flow through the posterior communicating and ophthalmic arteries. He was successfully treated by carotid artery stenting. No new neurologi...

A 52-year-old man presented with transient monocular blindness that was both spontaneous and exacerbated by exertion. Dynamic orbital CT revealed a delay in the perfusion of the left optic nerve head suggestive of a steal phenomenon. Subsequent selective arteriography demonstrated an arteriovenous fistula between the falx artery originating from the ophthalmic artery and the superior sagittal v...

We report a case of an internal carotid artery (ICA)-ophthalmic artery aneurysm with penetration of the opticnerve. In addition, this case penetrated the falciform ligament, which severely disturbed optic canal unroofing during surgery. This is the first reported case in which penetration of the optic nerve and falciform ligament has been shown. To remove the anterior clinoid process in this ca...

seen on color photography (Figure 2). Her visual acuity loss and fundus findings were attributed to choroidal infarction that occurred immediately postoperatively. A cerebral internal carotid artery angiogram performed 4 days postoperatively, once her proptosis resolved, revealed a surgical clip at the expected location and no evidence of a clip or obstruction at the level of the ophthalmic art...

Five cases of ipsilateral pupillary dilatation that developed during local intraarterial infusion of papaverine are reported. All patients were being treated for symptomatic vasospasm secondary to subarachnoid hemorrhage. In each case, the tip of the infusion catheter was positioned in the internal carotid artery in close proximity to the ostium of the ophthalmic artery. Pupillary dilatation in...

Intracranial aneurysm in twins is a rare clinical disease entity. Only 15 cases have been described in the literature. We report on a pair of identical twins with intracranial aneurysms. One presented with subarachnoid haemorrhage; digital subtraction angiography showed a left posterior communicating artery aneurysm, which was treated by coiling. The patient's twin sister was called for screeni...
