Intermittent ophthalmoplegia.

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...

Congenital external ophthalmoplegia.

Abiotrophic ophthalmoplegia externa.

THE various names given to the condition of ptosis and progressive ophthalmoplegia first described by von Graefe (1868), reflect views regarding the undecided aetiology of this condition, e.g. chronic progressive nuclear ophthalmoplegia, ocular myopathy, progressive muscular dystrophy involving the extra-ocular muscles, etc. M6bius (1900) had named the condition "progressive nuclear ophthalmopl...

Optokinetic asymmetry in internuclear ophthalmoplegia.

The reeognltlon of internuelear oph­ thalmoplegla in patients In whom there is full range of adduetion rests on the "dys­ metria test" and the "optokinetie test." 80th the dysmetria present wlth rapid re­ fixations and the optokinetle asymmetry are diseussed in terms of the neuro­ physiologie mechanlsm behind the slow addueting saeeades in internuelear oph­ thalmoplegla.
