A member asked:

Since myasthenia gravis is a systemic autoimmune disease, why does it often present with asymmetrical ptosis (instead of bilateral)?

A doctor has provided 1 answer

Fluctuating weakness: Myasthenia is a neuromuscular disease characterized by fluctuating weakness, not all muscles are affected at the same time or to similar degrees.
