Ptosis Surgery in Patients with Myasthenia Gravis: A Useful Adjunct to Medical Therapy

ABSTRACT Introduction: Medical management can have limitations in improving ptosis in patients with myasthenia gravis (MG). We present our experience of ptosis surgery in MG. Materials and Methods: Clinical records of all patients with MG undergoing ptosis surgery from September 2007 to November 2013 in a single center were retrospectively reviewed. Change in upper marginal reflex distance (uMRD) was the main outcome measure. Results: Sixteen external levator advancement (ELA) procedures were performed on 11 MG patients. Fourteen of 16 procedures had pre- and postoperative uMRD documented. Thirteen of 14 procedures had improved lid height; mean increase in uMRD was 2.4 mm (P=0.0005651). Two patients required secondary lid elevation. Postoperative complications included more noticeable diplopia (n=1) and exposure keratopathy (n=1). Conclusion: Ptosis surgery is a useful adjunct to medical therapy to improve lid height in MG patients with ptosis. Risks of diplopia and exposure keratopathy should be discussed with the patient pre-operatively.
