Outcome Measures

Primary Outcomes (1)

  • change of extraocular muscle volume and orbital fat volume by MRI

    3D MRI image will be established and the volume of extraocular muscle and orbital fat will be calculated by the same advanced programmer who is blinded of the pre- or post- treatment images order. A higher score means a better outcome.

    at month 6

Secondary Outcomes (3)

  • change of exophthalmos

    at month 6

  • change of Quality of Life

    at month 6

  • change of eyelid aperture, lid retraction and lid lag

    at month 6
