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.
