Seeking spark- ocular myasthenia gravis in a juvenile – an Indian case report
Abstract
Myasthenia gravis (MG) is a rare autoimmune disorder affecting neuromuscular junction by muscle weakness. Myasthenia gravis can be generalized or localized as ocular myasthenia gravis. Case presentation: We report an 8-year-old boy who presented with 10 days history of drooping of both eyelids and 8 days history of diplopia. Examination revealed bilateral ptosis. A diagnosis of Juvenile Ocular Myasthenia gravis was made when symptoms improved with intramuscular Edrophonium administration. He was commenced on oral Neostigmine at a dose of 2mg/Kg/ day,4 hourly in divided doses and is on regular follow up and had a good response. Conclusion: Ocular Myasthenia gravis (OMG) is a rare disease in itself. A high index of suspicion is required in a juvenile as it is even rarer.
