Özet:

Myasthenia Gravis is an autoimmune disease characterized by muscle strength loss due to dysfunction at the neuromuscular junction. The disease process most often begins at the adolescence and early adulthood. If the disease involves only ocular muscles, the term ocular myasthenia is used. While ocular symptom and signs are present in up to half of the myasthenia gravis patients, only 15% of the patients’ prognosis is dominated by sole ocular symptoms. The classic triad of the disease includes ptosis, diplopia and weakness of the ocular muscles. Ptosis accompanies the clinical picture in 90% of the cases but only rarely does the disease stay with ptosis as the only clinical symptom. Two- thirds of the ocular myasthenia gravis cases transform into generalized myasthenia and one-third remain as ocular myasthenia. We present a 67 year-old patient who applied to our clinic with the chief complaint of vertical diplopia.
