The ice pack test, or ice-on-eyes test, is performed by holding an ice cube, wrapped in a towel or a surgical glove, over the levator palpebrae superioris muscle of a ptotic eye for 2–10 min. Improvement of ptosis is said to be specific for myasthenia gravis, perhaps because cold improves transmission at the neuromuscular junction (myasthenic patients often improve in cold as opposed to hot weather).
