Dr. Pedro Beleza – Serviço de Neurologia / Hospital São Marcos Largo Carlos Amarante, Apartado 2242 4701-965 Braga Portugal. E-mail: [email protected] In multiple sclerosis (MS), ocular motor disturbances such as nystagmus or internuclear ophthalmoplegia are frequent and their pathophysiological processes are relatively well known. On the contrary, other rare and not so well studied manifesta...

acute idiopathic peripheral facial paralysis (bell's palsy) is the most common disorder of the facial nerve. most patients recover completely, although some have permanent disfiguring facial weakness. many studies have attempted to identify an infectious etiology for this disease. although the cause of bell's palsy remains unknown, recent studies suggest a possible association with herpes simpl...

purpose: to report three cases of classic cranial syndromes with involvement of the third and sixth nerves with comparison of their clinical and radiological findings and results of treatment. case report: three patients were referred to labbafinejad strabismus clinic because of diplopia and eye deviation after an attack of eclampsia (one case) and head trauma (two cases). they had extraocular ...

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...

Ocular bobbing is a distinctive movement disorder occurring in a variety of related forms herein classified as `typical', `monocular', and `atypical'. `Typical' ocular bobbing occurs in patients with paralysis of horizontal conjugate eye movements and consists of abrupt, spontaneous downward jerks of the eyes with a slow return to the mid position. The `monocular' type reflects co-existing unil...

This paper sketches the early history of pituitary apoplexy, a disorder later fully described in 1950 by Brougham, Heusner and Adams. Haemorrhage or necrosis in an adenoma causes a characteristic sudden drowsiness, stupor or coma, headache and stiff neck, ocular palsy, and impaired acuity with visual field loss owing to optic nerve or chiasmal compression. The associated endocrinopathy and mana...

A number of mechanisms other than direct orbital injury have been suggested to explain the fourth nerve palsy that may follow severe head injury. The mechanisms include brain-stem contusion or hemorrhage affecting the fourth nerve nucleus or fascicle and compression or stretching of the nerve at the tentorium or at other vulnerable locations along its subarachnoid course. In this patient, the f...

footdrop is a relatively common deficit among the neurological disorders, which has different causes with various levels of involvement in neuromuscular system, including central nervous system (brain cortex, spinal cord), fifth lumbar root, peripheral nerves and muscles. peroneal nerve injury at the fibular head has been reported to the most common cause of foot drop, which can be due to infar...
