Treatment Results of Endoscopic Transnasal Orbital Decompression for Graves' Orbitopathy-A Single-Center Retrospective Analysis in 28 Orbits of 16 Patients.

Graves’ orbitopathy (GO) is an extrathyroidal manifestation of Graves’ disease (GD), which can be associated with corneal ulcerations or optic neuropathy in severe forms. Transnasal endoscopic orbital decompression (TEOD) is a surgical procedure performed in order to decrease the intraorbital pressure by removing part of its bony borders in cases with excessive mass in orbit. The aim of this study was to present the results and evaluate the efficacy of TEOD for GO.

RAGE and HMGB1 Expression in Orbital Tissue Microenvironment in Graves' Ophthalmopathy.

Graves' ophthalmopathy (GO) is a chronic autoimmune inflammatory disorder involving orbital tissues. A receptor for advanced glycation end products (RAGE) and its ligand high mobility group box 1 (HMGB1) protein trigger inflammation and cell proliferation and are involved in the pathogenesis of various chronic inflammatory diseases. This study was aimed to evaluate RAGE and HMGB1 expression in GO to determine its potential clinical significance.

Immunological Aspects of Graves' Ophthalmopathy.

The body's autoimmune process is involved in the development of Graves' disease (GD), which is manifested by an overactive thyroid gland. In some patients, autoreactive inflammatory reactions contribute to the development of symptoms such as thyroid ophthalmopathy, and the subsequent signs and symptoms are derived from the expansion of orbital adipose tissue and edema of extraocular muscles within the orbit. The autoimmune process, production of antibodies against self-antigens such as TSH receptor (TSHR) and IGF-1 receptor (IGF-1R), inflammatory infiltration, and accumulation of glycosaminoglycans (GAG) lead to edematous-infiltrative changes in periocular tissues.

[Endoscopic decompression of orbit in Graves' orbitopathy].

Graves' orbitopathy (GO) is an extrathyroidal manifestation of Graves' disease (GD). The majority of patients has mild form of the disease, with no need of additional treatment. A few percent of patients can have a severe or very severe course of disease.
