Danish clinicians reviewed 350 records of patients with ocular or generalised forms of autoimmune myasthenia :
- clinical, electrophysiological and serological data were compiled and compared,
- 15.7% of patients had ocular myasthenia,
- the onset was later than in generalised forms, with lower levels of autoantibodies against the acetylcholine receptor (ARch),
- diagnostic odyssey was also longer, and symptomatic treatment was generally less aggressive,
- other parameters such as gender, the presence of other autoimmune diseases, or the time taken to obtain a therapeutic response were not correlated.
This work will be useful in better characterising the two main expressions of autoimmune myasthenia.
