About this trial

This is an interventional screening trial for Thyroid Associated Ophthalmopathy focused on measuring Doxycycline, Thyroid Associated Ophthalmopathy, Extraorbital muscle, Orbit fat volume, Multi-modal image

Eligibility Criteria

18 Years - 70 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Informed consent
  • Age 18-70 years old
  • Diagnosed with TAO

Exclusion Criteria:

  • Sight-threatening TAO with dysthyroid optic neuropathy
  • Allergy of tetracycline
  • Have contraindications of MRI(metal pacemaker, fake teeth, foreign body and other materials which will disturb the examination)

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

doxycycline

Arm Description

patients administrated with doxycycline tablets 100mg orally per day

Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

change of exophthalmos
exophthalmos will be measured by the same investigator using the same Hertel instrument. A higher change of exphthalmos means a better outcome.
change of Quality of Life
The score of quality of life will be assessed by the same investigator using GO-QoL. The better change of quality of life means a better outcome.
change of eyelid aperture, lid retraction and lid lag
the values will be measured by the same investigator using the same millimeter ruler and the higher values change, the better the outcome is.

5. Study Description

Brief Summary
This study aims to evaluate the efficacy of doxycycline treating Thyroid Associated Ophthalmopathy by multi-modal image.
Detailed Description
Thyroid Associated Ophthalmopathy is one of autoimmune orbital diseases characterized by enlargement of the extraocular muscles and increase in fatty or/and orbit connective tissue volume affecting the appearance and visual function of the eyes. Different degrees of exophthalmos, eyelid aperture, lid retraction and lid lag are common symptoms apprearing in TAO. The improvement of exophthalmos is usually measured with Hertel instrument and the change of eyelid is measured with millimeter ruler. All these measurements are subjective, low reliable and less accurate. TAO can be classified into active phase and inactive phase according to the activity score and wait-and-see or surgery are widely chosen for patients in inactive phase. But still a progression and reoccurrence can be a big challenge for ophthalmologists. This is a perspective cohort study to evaluate the efficacy of doxycycline in TAO by multi-model image.
