Abstract:
(Refer to page 133)
Answer: Ocular myasthenia gravis
and an ‘ice pack test’, a two minute
application of ice (wrapped in a
clean towel or other protective covering)
to the affected levator muscle.
Myasthenia gravis (MG) is an acquired autoimmune
disease caused by antibodies to the
acetylcholine receptors at the neuromuscular
junction of skeletal muscle. The resultant defect
in neuromuscular transmission causes
muscle fatiguability and weakness. Weakness
may localise purely to eye muscles termed
ocular myasthenia or may affect other skeletal
muscle termed generalised MG. About 50
to 70% of ocular myasthenia will eventually
develop generalised MG.
