Diplopia, Third Nerve Palsies, and Sixth Nerve Palsies
نویسنده
چکیده
Ocular motor defi cits are common clinical manifestations of neurological emergencies, with third (oculomotor) and sixth (abducens) paresis among the most frequent. This chapter focuses on recognition, diagnosis, and treatment of these cranial neuropathies in true neurological emergencies that carry a high risk of major morbidity or mortality if left undiagnosed. Emergencies discussed include alterations in intracranial pressure, intracranial aneurysms, fungal sinusitis, giant cell arteritis, meningitis, pituitary apoplexy, stroke, and Wernicke’s encephalopathy.

متن کاملDiabetes mellitus-associated ocular motor nerve palsies.
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...
متن کاملCombined fourth and sixth cranial nerve palsy after lumbar puncture: a rare complication. A case report.
Palsies of cranial nerves are well-known complications after lumbar puncture. Sixth nerve palsies are the most common. They normally occur 4 to 14 days after the lumbar puncture and spontaneously recover in a few weeks or months.

متن کاملRadiation-induced ocular motor cranial nerve palsies in patients with pituitary tumor.
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 ...
متن کاملDiplopia due to ocular motor cranial neuropathies.
PURPOSE OF REVIEW Determining which cranial nerve(s) is (are) involved is a critical step in appropriately evaluating a patient with diplopia. RECENT FINDINGS New studies have looked at the various etiologies of cranial nerve palsies in the modern imaging era. The importance of the C-reactive protein test in evaluating the possibility of giant cell arteritis has recently been emphasized. SU...
