The following are indications to perform neuroimaging studies (eg, MRI, CT) of the orbit and brain:

  • History not consistent and onset not clear

  • Other neurologic findings along with ptosis

  • Orbital wall fracture suspected with history of trauma

  • Visible or palpable lid mass

  • Orbital tumors (eg, lymphoma, leukemia, rhabdomyosarcoma) suspected
