If Thymectomy Reduces the Risk of Progression of Ocular to Generalized Myasthenia Gravis, Who Should Receive it?

In this issue of Neurotherapeutics, Li et.al. report a large retrospective study of the beneficial effects of thymectomy on the progression of ocular myasthenia gravis (OMG) to generalized MG (GMG) (Huanhuan et al. in Neurotherapeutics XX, 2021 ). This paper demonstrates a more than 50% reduction in the risk of GMG when a thymectomy was performed on these patients. The authors conclude with the recommendation that well-designed clinical trials be performed to evaluate the potential that thymectomy in OMG reduces the burden of GMG.
