EP.30Usefulness of extraocular muscle imagery in the diagnosis of myasthenia gravis and chronic progressive external ophthalmoplegia

Myasthenia gravis (MG) and mitochondrial disorders may induce oculomotor troubles or ptosis. When these troubles are isolated, differential diagnosis between both diseases can be difficult. The aim of our study is to compare extraocular muscle (EOM) mass in patients affected by chronic progressive external ophtalmoplegia (CPEO) due to mitochondrial disorders and in patients presenting with MG. We retrospectively collected data from MG patients and CPEO referred to our French neuromuscular center.
