Rest Test: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Myasthenia Gravis:
During the rest test the patient places a glove filled with cotton (a placebo) over the more ptotic eyelid while holding the eyes closed for 2 minutes. Complete or almost complete resolution of ptosis or at least a 2-mm increase in palpebral fissure width constitutes a positive response to these maneuvers. It is very important to evaluate the improvement immediately following the test, as the lids may quickly begin to droop again.

NOTE: only 1 study.
