“…MG includes early-onset myasthenia gravis (EOMG) and late-onset MG (LOMG), generally defined by a cut-off age of 65 years [ [3] , [4] , [5] , [6] ]. It was high sensitive to nondepolarizing neuromuscular blocking agent (NMBA) and multiple medications [ [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] ]. Due to advancing age, ptosis in MG were often mistaken for the loose and sagging skin around the eyelids caused by aging, while diplopia was thought to be caused by macular degeneration and cataracts.…”
