Teenager with Acquired Strabismus: Do I Image? Do I Operate? (PDF) | Myasthenia gravis (MG) is an autoimmune disorder involving the neuromuscular junction of skeletal muscles. Adult and pediatric prevalence estimates are approximately 2-30 and 1-5 per million person years, respectively; 10-15% of all cases occur in children.

Treatment of Ocular Myasthenia Gravis | Myasthenia gravis is caused by pathogenic autoantibodies to the postsynaptic neuromuscular junction. Clinically, this may affect any of the skeletal muscles causing variable weakness, which worsens with continued muscle activity. Ocular myasthenia gravis (OMG) may affect the levator palpebrae superi... | Ocular Myasthenia; Treatment; Therapy; Pyridostigmine; Corticosteroids; Thymectomy; Azathioprine; Mycophenolate Mofetil | Neuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu |

Pediatric Neuromuscular Disorders | Disruption of the neuromuscular transmission, either at the presynaptic or postsynaptic junction, may result in fatigability and muscle weakness that commonly affect ocular motility and lid movement. We will review several of the pediatric disorders that influence neuromuscular transmission. | Pediatric Myasthenia Gravis; Congenital Myasthenia Gravis; Botulism | Neuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu |

Prednisone Does Not Effect Acetylcholine Receptor Antibodies in Ocular Myasthenia Gravis | Myasthenia Gravis is an autoimmune disorder characterized by a reduction of available postsynaptic acetylcholine receptors (AChR) on the end plates of the neuromuscular junction. | Ocular Myasthenia Gravis; Acetylcholine Receptor Antibody; Generalized Myasthenia Gravis; Prednisone | Neuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu |

Myasthenia Gravis: Time for Thymectomy? | Thymectomy has been considered as a treatment option for Generalized Myasthenia Gravis (GMG) since the association was first described (I am told, as I do not read German) by Lacquer and Weigert in 1901. | Myasthenia Gravis; Ocular Myasthenia Gravis; Thymectomy; Thymoma; Non-thymomatous Thymectomy | Neuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu |

Electrophysiologic Testing for Acquired and Congenital Myasthenia Gravis | Repetitive nerve stimulation, needle electromyography, and single fiber EMG are useful in sorting out myasthenia gravis from clinical look-alikes. Routine nerve conduction studies are almost always normal in myasthenia gravis but are abnormal in the Lambert-Eaton Syndrome, botulism, some intoxicatio... | Electrophysiologic Testing; Acquired Myasthenia Gravis; Congenital Myasthenia Gravis | Neuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu |

Cogan Lid Twitch | A 50-year-old woman presented with ptosis of her left eyelid for 6 months. Several exam findings including variable and fatigable ptosis, and Cogan lid twitch, raised suspicion for Myasthenia Gravis. Acetylcholine receptor binding, blocking, and modulating antibodies were negative, and single fiber ... | Lid Twitch; Myasthenia Gravis | Neuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu |

Management Options In Myasthenia Gravis | The attendee will be able to describe the treatment options for patients with both generalized and ocular myasthenia gravis.

Intravenous Methylprednisolone Treatment of Ocular Myasthenia Gravis | Ocular myasthenia gravis is a chronic disease generally requiring years of treatment. Treatment consists of either Mestinon or immunosuppressive agents. Many patients with ocular myasthenia gravis are elderly and long term prednisone treatment is fraught with complications.

Myasthenia Gravis | Diagnosis Clinical Criteria are the most important. The history of fluctuation of symptoms should make the diagnosis suspect.
