[Bone marrow-derived fibrocytes and thyroid-associated opthalmopathy].

Thyroid-associated opthalmopathy(TAO) is a common autoimmune syndrome affecting the thyroid and orbit, which can result in the fibrosis of extraoular muscles and hyperplasia of adipose tissue. Advanced TAO patients could even lose vision caused by cornea ulcer and congestion of optic nerve from expansion of the extraocular muscles and orbit fat. Currently, there are no therapies shown to prevent it, because its cellular and molecular mechanisms are not clear. Some studies have recently implicated bone marrow-derived fibroblast-like, called fibrocytes are involved in the pathogenesis of TAO. We reviewed and summarized the research advances of TAO and also the relationship between the fibrocytes and pathogenesis of TAO in the paper. (Chin J Ophthalmol, 2017, 53: 470-473).
