BACKGROUND: Rectus muscle restriction is a common finding in thyroid eye disease (TED). Typically, restricted muscles are recessed to address strabismus and diplopia. However, some patients have residual strabismus following maximal recession of a restricted muscle. The purpose of this study was to report outcomes following resection of the lateral rectus muscle after maximal recession of the medial rectus muscle in patients with TED. METHODS: The medical records of patients with TED who underwent lateral rectus resection between 1998 and 2015 were reviewed retrospectively...

PURPOSE OF REVIEW: To report the most recent therapeutic advances of thyroid eye disease (TED) and offer general recommendations for management of TED. RECENT FINDINGS: Treatment of Graves ophthalmopathy is traditionally based on the use of high doses of corticosteroids and/or radiotherapy (RT) to decrease the activity of the disease, with the subsequent proptosis, strabismus and eyelid deformites treated with different surgical procedures. In recent years, the evidence that oxidative stress plays a relevant role in exacerbating TED severity has encouraged the use of antioxydative agents such as selenium, which has shown a capacity in limiting the disease progression...

INTRODUCTION: Glucocorticoids represent the therapy of choice for active and moderate-to-severe Graves̕ orbitopathy (GO). In some patients, rituximab, a monoclonal antibody against the cluster of differentiation (CD) 20 receptor of B-lymphocytes, can serve as a second-line or an alternative treatment. The effect of very low-doseof rituximabon the clinical activity of GO and corresponding clinical or laboratory changes is reported. MATERIAL AND METHODS: Changes of Clinical Activity Score (CAS) for GO, proptosis, levels of thyroid-stimulating hormone receptor antibodies, and depletion of CD19+ and CD20+ B-lymphocytes were determined in ten patients (two men and eight women) with active moderate-to-severe GO treated with a single 100-mg dose of rituximab...

Thyroid-associated ophthalmopathy (TAO) is a common autoimmune syndrome affecting the thyroid and orbit. It can result in the fibrosis of extraoular muscles and hyperplasia of adipose tissue. The mechanism of TAO is not clear and there was few effective treatment. Recently, orbital decompression was performed on more and more patients. The surgery can improve the appearance of the patient and relieve the symptoms caused by the high orbital pressure. Therefore, it is necessary to re-evaluate the clinical value of the orbital decompression and surgical indications...

Granulomatous orbital cellulitis is one of the most common ocular manifestations of granulomatosis with polyangiitis (Wegener's). The process is often refractory to conventional immunosuppressive therapy and requires a more radical treatment approach. However, surgical experience with this type of patients is limited. There have been just a few reported cases of orbital decompression in such patients and many authors have doubted the appropriateness of the procedure, since it is associated with a high risk of potentially fatal complications...

Highly coordinated iron and cobalt nitrides were successfully synthesized via direct chemical reaction between a transition metal and molecular nitrogen at pressures above approximately 30 GPa using a laser-heated diamond anvil cell. The synthesized novel transition metal nitrides were found to crystallize into the NiAs-type or marcasite-type structure. NiAs-type FeN could be quenched at ambient pressure, although it was gradually converted to the ZnS-type structure after the pressure was released. On the other hand, CoN was recovered with ZnS-type structure through a phase transition from NiAs-type structure at approximately a few gigapascals during decompression...

Injury to the peripheral sensory branches of the trigeminal nerve can follow a wide variety of craniofacial injuries. Many patients with facial fractures complain about the symptom of numbness to the distribution of injured nerve, which is indicative of hypoesthesia. Hyperesthesia involving the infraorbital nerve is rare in comparison to hypoesthesia secondary to facial trauma. The authors report on 2 patients with infraorbital nerve hyperesthesia in surgically repaired orbital fracture patients. Surgical decompression of the infraorbital nerve led to rapid resolution of hyperesthesia...

INTRODUCTION: Silent sinus syndrome is an unusual cause of progressive enophthalmos and hypoglobus due to atelectasia of the maxillary sinus associated with osteolysis of the orbital floor. This syndrome is classically idiopathic, but the term is also used to describe traumatic or iatrogenic (surgical orbital decompression) cases. CASE REPORT: We report the case of a 33-year-old man who presented with a left orbital trauma without functional disorder. Computed tomography (CT) scan revealed a nondisplaced fracture of the left orbital floor...

REVIEW
Esra Şahlı, Kaan Gündüz
Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves' disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. There is an increased volume of extraocular muscles, orbital connective and adipose tissues. Clinical findings of thyroid-associated ophthalmopathy are soft tissue involvement, eyelid retraction, proptosis, compressive optic neuropathy, and restrictive myopathy...
