Overview
The most widely accepted classification of myasthenia gravis is the Myasthenia Gravis Foundation of America Clinical Classification.[1] This classification system categorizes the disease by the muscles that are predominantly effected.
Classification
- Class I: Any eye muscle weakness, possible ptosis, no other evidence of muscle weakness elsewhere
- Class II: Eye muscle weakness of any severity, mild weakness of other muscles
- Class IIa: Predominantly limb or axial muscles
- Class IIb: Predominantly bulbar and/or respiratory muscles
- Class III: Eye muscle weakness of any severity Moderate weakness of other muscles
- Class IIIa: Predominantly limb or axial muscles
- Class IIIb: Predominantly bulbar and/or respiratory muscles
- Class IV: Eye muscle weakness of any severity, severe weakness of other muscles
- Class IVa: Predominantly limb or axial muscles
- Class IVb: Predominantly bulbar and/or respiratory muscles (Can also include feeding tube without intubation)
- Class V: Intubation needed to maintain airway
