An isolated ocular motor nerve palsy is defined as dysfunction of a single ocular motor nerve (oculomotor, trochlear, or abducens) with no associated or localizing neurologic signs or symptoms. When occurring in patients aged 50 or older, the most common cause is microvascular ischemia, but serious etiologies such as aneurysm, malignancy, and giant cell arteritis should always be considered. In...

CASE REPORT Two patients (80 and 67 year-old) presented with diplopia for a sudden right 3rd cranial nerve palsy without other ocular or systemic symptoms related to temporal arteritis. Erythrocyte sedimentation rate and C-reactive protein levels were normal. Subsequent biopsy of the superficial temporal artery confirmed the diagnosis of temporal arteritis. DISCUSSION Patients with ocular ner...

This paper is limited to the consideration of acquired ocular palsies attributed to involvement of the cranial nerve pathways, i.e. lower motor neurone lesions. It is not concerned with supranuclear problems, retraction syndromes, myasthenia, dysthyroid eye disease, or blow-out fractures. The words palsy, paresis, and paralysis tend to be used interchangeably, but usually paresis means a mild a...

In this case report we present a diabetic patient with isolated, pupil-sparing, incomplete inferior division third cranial nerve palsy. Laboratory tests for the evaluation of thyroid function, infection, myasthenia gravis and autoimmune diseases were normal. Cranial computed tomography, magnetic resonance imaging and magnetic resonance angiography also showed normal findings. Accordingly, diabe...

Isolated fourth nerve palsy is usually benign. The most common etiologies are congenital, traumatic, ischemic, and idiopathic causes. Extensive evaluations for isolated fourth nerve palsies are generally not indicated, but more intensive evaluation for underlying etiology may be necessary for nonisolated or bilateral fourth nerve palsies. Evaluation of ocular torsion enables differentiation of ...

E diagnosis of ocular motor palsy enables prognosis and assists in treatment. In adults, the most common causes of ocular motor palsy are aneurysm, microvascular disease (such as diabetes mellitus [DM]), and trauma. In patients with DM, ocular motor nerve palsy is a common cause of acquired diplopia and/or ptosis.1,2 In diabetics, the calculated incidence of cranial nerves palsies is 5-10 times...

We describe three patients who experienced onset of a microvascular ocular motor nerve palsy in the setting of sudden emotional stress. Such emotional states are accompanied by a marked increase in sympathetic tone in some individuals. Mechanisms by which these autonomic changes might produce an ischemic cranial nerve palsy include intra-cranial vasoconstriction and transient systemic hypotensi...

Measurements of the dynamics of the eyes in ocular motor nerve palsies may aid diagnosis, characterize peripheral and central palsies, and reveal adaptive properties of the brain. Saccadic and vestibulo-ocular reflex (VOR) functions of patients with peripheral and central sixth, and peripheral third and fourth nerve palsies were studied by three dimensional magnetic field search coil oculograph...

BACKGROUND Radiation therapy is often used in the treatment of pituitary tumor. Diplopia due to radiation damage to the ocular motor cranial nerves has been infrequently reported as a complication in this clinical setting. METHODS Retrospective case series of 6 patients (3 men and 3 women) with pituitary adenoma, all of whom developed diplopia following transsphenoidal resection of pituitary ...

purpose: to evaluate the results of jensen procedure in correction of ocular deviation in patients with complete sixth nerve palsy. methods: hospital records of patients with complete sixth nerve palsy who underwent jensen procedure at khalili hospital of shiraz during 1993-2002 were studied and results of the operation were evaluated. results: of 18 patients including 14 male and 4 females, 19...
