one of the important causes of strabismus in all ages is extraocular muscles paralysis due to 3rd, 4th and 6th cerebral nerve palsies. exact and on-time treatment can result in improvement of deviation, am-blyopia and abnormal head posture. we studied epidemiological characteristics of extraocular muscles paralysis. this retrospective study performed on 131 subjects (58% male). records of patie...

isolated third nerve palsy develops in numerous intracranial pathologies such as closed head trauma, tumor, and aneurysm. this report describes a 61 years old female with an abrasion on the left forehead and ptosis of the left eye. initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. high-resolution and multi-axial enhanced mag...

purpose: to determine the distribution of oculomotor, abducens, and trochlear nerve palsies in diabetic patients with ocular nerve palsy. methods: this study was performed on all diabetic patients who referred to ophthalmology and neurology clinics at yazd medical science university because of ocular palsy from march 2004 to october 2005. signs and symptoms of the disorder were evaluated. resul...

Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simpl...

purpose: to evaluate demographics and therapeutic outcomes of patients with third nerve palsy who had been treated between 1999 to 2009 at labbafinejad medical center. methods: in this retrospective study, we evaluated 52 patients with third nerve palsy who had been referred to labbafinejad medical center over a ten-year period. results: in this retrospective study, subjects who had been treate...

Oculomotor nerve palsy frequently occurs because of external compression by an internal carotid-posterior communicating artery aneurysm and diabetes mellitus. In addition, pontine infarction, cavernous sinus tumors, demyelinating disease, and autoimmune disorder are well-known causes of oculomotor nerve palsy. However, cases of complete oculomotor nerve palsy by neurovascular conflicts presente...

Although oculomotor nerve palsy, which is common in diabetes, is considered an ischemic mononeuropathy, the susceptibility of the oculomotor nerve to ischemic insult is not well understood. We analyzed the density of endoneurial microvessels of the oculomotor nerve and compared it with that of the sural nerve in non-diabetic patients. The mean vascular density of the oculomotor nerve (23 ± 8.4/...

Objective To report a rare case of unruptured internal carotid-posterior communicating artery (IC-PC) aneurysm splitting the oculomotor nerve treated by clipping and to review the previously published cases. Case Presentation A 42-year-old man suddenly presented with left oculomotor paresis. Three-dimensional digital subtraction angiography (3D DSA) demonstrated a left IC-PC aneurysm with a bul...

BACKGROUND The purpose of this study was to consider the mechanism of isolated oculomotor nerve palsy after minor head trauma. CASE DESCRIPTION We report a rare case of delayed and isolated oculomotor nerve palsy following minor head trauma. A 19-year-old boy complained of double vision 1 day after a minor head trauma. Neuro-ophthalmic examination showed isolated left oculomotor nerve palsy. ...
