title: The place of the ice pack test in the diagnosis of myasthenia gravis.
abstract: In the evaluation of ptosis, the ice pack test is a simple, quick, bedside method to ascertain whether it is of myasthenic origin, which requires no specialised medication or equipment and is free of reported adverse effects. Pooling of published studies suggests very high sensitivity, specificity and likelihood ratios, but standardisation and operationalisation of the test are important. False-negative tests may occasionally occur.
