The ice-pack test and single fiber electromyography in the diagnosis of ocular myasthenia

Takeaway

  • The ice-pack test (IPT) is as accurate as single fiber electromyography (SF-EMG) in the diagnosis of ocular myasthenia (OM), in individuals presenting with ptosis.

Why this matters

    SF-EMG is regarded as the most sensitive test for OM, but it is often not readily available.
