Experimental internuclear ophthalmoplegia.
A midline experimental lesion separating the medial longitudinal fasciculi at and below the level of the abducens nuclei without damaging either fasciculus at the level of the nuclei has produced defects of ocular motility resembling those of clinical internuclear ophthalmoplegia. Electromyographic recordings during lateral gaze demonstrate: (1) lack of inhibition of the lateral rectus muscle i...

متن کاملInternuclear ophthalmoplegia: recovery and plasticity.
We studied refixational eye movements of a patient during the gradual resolution of an internuclear ophthalmoplegia (secondary to head trauma) in an attempt to determine the relative contributions of both medial longitudinal fasciculus (MLF) recovery and secondary central plastic changes. Adduction-refixational eye movements in the affected eye consisted of an initial fast (saccadic) portion fo...
متن کاملPernicious anaemia.
DEFICIENCY of vitamin B12 (cyanocobalamin) in man results in a macrocytic animia, leucopa2nia, the appearance of megaloblasts and giant band cells in the marrow, reduced formation of platelets, and also-changes in the peripheral and central nervous systems. In temperate climates the most common cause of vitamin B12 deficiency is pernicious anaemia. This is by no means a rare disease, having an ...
متن کاملBilateral internuclear ophthalmoplegia following head trauma
A 35‐year‐old male presented to the emergency department (ED) after a traffic accident. The patient had a frontal scalp laceration, brief loss of consciousness with retrograde amnesia, headache, and dizziness. There was no evidence of ocular or periorbital trauma. Initially, brain computed tomography performed in the ED revealed no specific finding. After regaining full consciousness, the patie...
