AIM To present the results of endonasal endoscopic orbital decompression in patients with Graves' ophthalmopathy. METHODS Endonasal endoscopic orbital decompression was performed in 32 orbits of 21 patients with Graves' ophthalmopathy. In 17 patients the surgery was performed because of active ophthalmopathy non-responsive to conservative treatment, and in 4 patients for esthetic reasons. Pre...
Purpose To investigate juvenile Graves' ophthalmopathy (GO) signs and compare Graves' disease (GD) course in patients with or without GO. Patients and Methods There were analyzed data (visual acuity, proptosis, palpebral fissure measurements, clinical activity score (CAS), and the course of GD) of 67 children who have been newly diagnosed with GD. 26.9% of patients with GD had signs of ophtha...
Reactive oxygen species (ROS) are highly reactive molecules as they contain unpaired electron(s). They are formed by different cellular processes are involved in intracellular signalling, and are tightly regulated. A large number of antioxidant systems act as protective mechanism. Situation in which balance between oxidants and antioxidants is disturbed in favour of the oxidants is termed ‘oxid...
The TSH receptor (TSHR) on orbital fibroblasts (OF) is a proposed target of the autoimmune attack in Graves' ophthalmopathy. In the present study, we tested whether the novel low-molecular-weight (LMW) TSHR antagonist Org-274179-0 inhibits cAMP production induced by rhTSH, Graves' disease IgG (GD-IgG), or M22 (a potent human monoclonal TSHR stimulating antibody) in cultured and differentiated O...
Excess production of hyaluronan (hyaluronic acid [HA]) in the retro-orbital space is a major component of Graves' ophthalmopathy, and regulation of HA production by orbital cells is a major research area. In most previous studies, HA was measured by ELISAs that used HA-binding proteins for detection and rooster comb HA as standards. We show that the binding efficiency of HA-binding protein in t...
A 44 year old diabetic woman presented with diplopia and bilateral ptosis and mild exophthalmos. The patient was clinically euthyroid, the baseline thyroid function tests were normal, but the thyroid stimulating hormone response to thyrotrophin releasing hormone was flat. Computed tomographic scan and magnetic resonance imaging of the orbits showed left medial and inferior rectus muscle thicken...
Thyroid-associated ophthalmopathy (TAO) is a progressive eye disorder associated with thyroid autoimmunity, particularly Graves' hyperthyroidism, which is generally considered to have an autoimmune etiology. Eye muscle membrane proteins reportedly of 55 and 64 kDa are the best markers of the ophthalmopathy. The main focus of our recent studies has been to purify the pertinent proteins from porc...
Thyroid associated ophthalmopathy (TAO), a cardinal clinical pointer to diagnose Graves' disease (GD), is seen less frequently in our country than in the West, but can have sight threatening consequences. Smoking, diabetes, male gender, increasing age and radioactive iodine treatment for thyrotoxicosis are known precipitating factors for TAO. We report four cases of thiazolidinediones (TZD) pre...
Exophthalmos is typically associated with Graves' ophthalmopathy. Although originally described by Harvey Cushing, exophthalmos is an underappreciated sign of Cushing's syndrome. We present a case of a 38-year-old female who presented with severe bilateral proptosis and was subsequently diagnosed with Cushings disease. We discuss the possible mechanisms causing exophthalmos in patients with eit...
