Unilateral-external Ophthalmoplegia: ARare Presentation of Myasthenia Gravis.

Myasthenia gravis (MG) is a disease of autoimmunity with variable and diverse clinical presentations. The target tissue is neuromuscular junction of skeletal muscles, where efficient nerve impulse transmission is hampered leading to less effective muscle contraction. Patients of MG usually present with bilateral ptosis, diplopia and fatigability, which may or may not coexist with generalised weakness, dysphagia and dysarthria. A46-year male presented with unilateral ptosis and diplopia. Except for unilateral moderate ptosis and restriction of extraocular movements, ocular and systemic examination was normal. Both ice pack and tensilon tests revealed improvement in ptosis. Patient was advised tablet pyridostigmine and prednisolone; and a remarkable improvement was noticed within a week.
