151 Ocular Myasthenia Gravis - How Effective Is Low Dose Prednisone Long Term?Ocular myasthenia gravis (OMG) therapy should address three issues - restoration of normal binocular vision. prevention of deterioration to generalize MG (GMG), and avoiding significant adverse effects of treatment. Prior studies suggest that moderate dose followed by low dose daily prednisone can a...Myasthenia, Neuro-ophth & Systemic Disease (eg.

152 Treatment Outcome in Ocular Myasthenia GravisOcular Myasthenia Gravis (OMG) is an autoimmune disease that affects the neuro-muscular junction resulting in ptosis and/or diplopia without general or bulbar symptoms. OMG patients can suffer from disabling ocular symptoms. The outcome of treatment with OMG is poorly understood. Our aim is to asse...Myasthenia, Ocular Motility, Neuro-ophth & Systemic Disease (eg.

154 Mycophenolate Mofetil as First-Line Therapy for Ocular Myasthenia GravisOcular myasthenia gravis (OMG) may produce debilitating diplopia or ptosis leading to significant visual disability. Symptomatic treatment with pyridostigmine is frequently ineffective and immunosuppressive therapy with corticosteroids can have serious side-effects.Myasthenia; MycophenolateNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
155 Pediatric Neuromuscular Disorders (Slides)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; BotulismNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
156 Safety of Prednisone for Ocular Myasthenia GravisTreatment with chronic corticosteroids has been associated with frequent significant adverse effects.

161 A Case of Silent Sinus Syndrome Caused by a Dacryocystorhinostomy Presenting as Myasthenia GravisSilent Sinus Syndrome (SSS) is a rare entity defined as spontaneous, progressive enophthalmos and hypoglobus from maxillary sinus hypoplasia due to chronic maxillary sinus obstruction1.

162 The Effects of Edrophonium on Eyelid SaccadesThe first diagnostic use of an anticholinesterase in myasthenia gravis included observations on its effect on ptosis. Subsequently, the response of myasthenic eye movements to edrophonium has been extensively studied with quantitative techniques. However, the effect of this drug on lid dynamics has ...Edrophonium; Eyelid Saccades; Myasthenia Gravis; PtosisNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
163 Peripheral Inflammatory Processes Affecting Ocular Motor FunctionMyasthenia gravis is a disorder of neuromuscular transmission. Normally, acetylcholine is packaged into vesicles which are then released into the cleft at the neuromuscular junction. Receptors bind the acetylcholine to initiate depolarization of the muscle membrane.Ocular Myasthenia Gravis; Thyroid Ophthalmology; Miller-Fisher Syndrome; Neuromuscular Transmission DiseaseNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu

165 Chest CT Thymoma (Guest Lecture)The patient is a 46 year old woman who presented in July 1977 with horizontal double vision lasting two weeks. Three weeks later the left upper eyelid started to droop and by the end of the day the eye was closed. She had no ptosis of the right eye and no generalized fatigue.

167 Quantification of Saccadic Fatigability for a Diagnosis of Myasthenia GravisSymptoms of myasthenia gravis (MG) are characterized by fatigable and fluctuating weakness with repeated use of muscle. The diagnosis of MG was combined with clinical symptoms and ancillary tests. However, each study has reported different sensitivity and specificity of the test, so there are variou...Myasthenia; Neuro-ophth & Systemic Disease (eg.

169 Differences and Similarities Between Idiopathic Intracranial Hypertension, Ocular Myasthenia Gravis, Optic Neuritis, and Horner's In Children Vs. AdultsPediatric neuro-ophthalmology is more than just neuroophthalmology of little people. Compared with neuro-ophthalmology in adults, in the pediatric subspecialty the diseases are different, with greater emphases on congenital malformations and genetic disorders and less on vascular problems.Idiopathic Intracranial Hypertension (Pseudotumor Cerebri); Pediatric Optic Neuritis; Ocular Myasthenia Gravis; Horner's SyndromeNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
170 Walsh & Hoyt: Pediatric Myasthenia GravisAutoimmune MG can occur at any age. One clinical challenge in ""juvenile-onset"" myasthenia is to distinguish antibody-mediated disease from gene mutations affecting NMJ ion channels. Juvenile-onset autoimmune MG differs little from adult-onset disease, except that it may improve with age. It respon...Ocular Motor System; Pediatric Myasthenia GravisNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
