Cranial nerve (CN) lesions are observed due to congenital, infectious, neoplastic formations, migraine and head trauma. Along with the patient's age, clinical findings neuroradiological imaging studies guide diagnosis. A 57-year-old female patient was brought emergency room (ER) by Emergency Medical Services (EMS) a motor vehicle accident. No medical history. She conscious, cooperative orientat...

An abnormal mydriasis of the pupil may be present after blunt contusion of the eye. Pro~ longed mydriasis indicates partial or complete rupture of the iris sphincter and may he permanent. 1 Anisocoria resulting from unilateral mydriasis may be associated with visual difficulties. Difficulties may be expected at nearwork because of the reduced depth of focus of the dilated eye. Other difficultie...

Two intraocular phenomena folloiuing sympathetic denervation—degeneration mydriasis and degeneration hyperemia of the iris—were studied in conscious albino rabbits. The superior cervical ganglion was removed on one side (denervation) and the preganglionic sympathetic trunk was cut on the control side. Mydriasis and hyperemia toere judged by comparing the two eyes. Mydriasis started about 14.5 h...

Hourly measurements of the transient mydriasis and intraocular pressure decrease after right cervical ganglionectomy and left cervical sympathotomy were simultaneously performed in conscious rabbits. The times of onset of these phenomena after the denervation were 14.51 0.21 hr. (n = 8) and 18.71 ± 0.78 hr. (n = 7), respectively. Their duration values were 18.01 ± 0.89 hr. (n = 8) and 18.81 ± 1...

PURPOSE To determine whether there is alpha 1-adrenergic receptor heterogeneity associated with the regulation of intraocular pressure (IOP) and mydriasis in rabbits, the authors tested the hypothesis by characterizing the ability of the selective alpha 1-adrenergic antagonist, bunazosin, to block the ocular hypertensive and mydriatic responses to alpha 1-adrenoceptor stimulation by either nore...

This study is to identity the clinical characteristics of mydriasis derived from nebulized ipratropium bromide in neurosurgical patients. We presented 3 patients with inhalation of ipratropium bromide associated mydriasis and reviewed the pertinent literature. Mydriasis was caused by nebulized ipratropium bromide leak from the mask into ipsilateral eye. When the medication was discontinued in t...

Objective. The aim of this study was to describe the indications and results of exploratory burr hole performed at the Departmental Teaching Hospital of Borgou (Benin). Methods. It was a retrospective study performed from January 2008 to February 2011. It concerned patients with a closed traumatic brain injury (TBI) in which an exploratory burr hole was performed. The selection criteria were un...
