Can myasthenia gravis be diagnosed with the 'ice pack test'? A cautionary note

A J Larner et al. Postgrad Med J. 2000 Mar.

Abstract

The ice pack test may be helpful in establishing that ptosis is due to ocular myasthenia gravis, since cold improves neuromuscular transmission. However, the role of the test in determining whether diplopia is of myasthenic origin has yet to be established.
