This thesis aims to firstly explore factors that contribute to a delayed diagnosis in Myasthenia Gravis (MG) in an Australian population to identify a need for improved diagnostic measures to reduce symptom burden. It demonstrates that both patient and institutional factors contribute to a delay. Secondly, it aims to compare the eye movement profiles of MG patients to healthy control participants using video eye-tracking to determine diagnostic utility. This study demonstrates that eye-movements may be a useful diagnostic marker.
