PURPOSE: To descirbe a series of patients in which Thyroid Associated Orbitopathy (TAO) occurred after periocular surgery. METHODS: A retrospective case review of patients who developed TAO in close temporal association with periocular surgical interventions and presented at the orbital clinic from 1997 to 2004. History of previous thyroid abnormality and the lack of TAO signs and symptoms before surgery were reviewed and analyzed. RESULTS: Nine patients that developed TAO in association with periocular surgery were identified. All were women with an average age of 59.3years. (range: 45-75 years). The patients divided into two groups. Group 1 consisted of four patients who had previously been diagnosed with Graves' hyperthyroidism (GH). They ranged in age from 48 to 75 years (average: 58.8 years). The diagnosis of GH had been made an average of 50.5 months (range: 12-96 months) before presentation with TAO. Group 2 consisted of five patients who had no previous history of thyroid abnormality. They ranged in age from 45 to 74 years (average: 60.2 years). No patients had any signs or symptoms of TAO before their recent presentation. CONCLUSIONS: Periocular surgery may lead to local inflammatory events that may contribute to the instigation of TAO in predisposed individuals

PURPOSE: To describe prominent premalar and cheek swelling as a previously undescribed clinical feature of thyroid-associated orbitopathy (TAO). DESIGN: Retrospective interventional case series. METHODS: A retrospective case review of patients with prominent premalar and/or cheek swelling and TAO was undertaken. All patients who presented from March 2002 to February 2005 with complaints of premalar and/or cheek swelling in TAO were analyzed. RESULTS: Six female patients between the ages of 28 and 66 years (average, 44.2 years) who had complaints of prominent premalar and/or cheek swelling and TAO were included in the study, among 326 new patients with TAO (incidence: 1.84%). Five of the 6 patients had Graves hyperthyroidism. One initially had Hashimoto thyroiditis, which converted to Graves hyperthyroidism. In all cases, TAO preceded the thyroid disease or developed simultaneously (average time from TAO to thyroid disease was 3.0 months). No patient had received corticosteroids before premalar and/or cheek swelling. The premalar and/or cheek swelling was bilateral in all cases, but 2 of 6 were asymmetric. No diurnal fluctuation or tenderness in premalar and/or cheek swelling was noted. All improved incompletely over several months. Brow, eyelid swelling, and orbital-fat hypertrophy on radiologic examination was coincidentally noted in 5 of 6 cases. Pretibial myxedema was noted in one case. One case was associated with another autoimmune disease (rheumatoid arthritis). CONCLUSIONS: Prominent premalar and cheek swelling should be considered among the clinical features of TAO. The true incidence will become apparent as we question and examine patients more carefully regarding this entity and as we review premorbid photographs

Adalimumab is a fully humanized IgG1 monoclonal antibody to tumor necrosis factor-a. We describe 2 patients (17 and 13 years of age) with refractory, steroid-dependent, recurrent nonspecific orbital myositis not controlled with standard immunosuppressive medications. Both improved with adalimumab treatment, allowing reduction in corticosteroid dosage without disease flare

PURPOSE: To examine the role of transnasal and transantral endoscopic surgical approaches in the management of apical orbital lesions. METHODS: Retrospective case series. RESULTS: Three patients underwent combined orbital and endoscopic surgery for treatment of apical orbital lesions. In two of these patients, the orbital apex was decompressed, which resulted in visual recovery. Using endoscopic approaches to the posterior orbit and orbital apex allowed better visualization, with minimal manipulation of tissues in an area where surgical access is limited. CONCLUSIONS: Apical orbital lesion management benefits from a multidisciplinary and individualized plan. Endoscopic approaches can be used to improve visualization and access to a difficult surgical area. They also allow extra instrumentation to be used through the relatively capacious paranasal sinuses. These advantages may obviate lateral orbitotomy in some situations. Although endoscopic techniques are useful for biopsy, debulking, and removal of orbital apex lesions, they may be more difficult to apply to an intraconal lesion at the orbital apex

A 79-year-old man with myelodysplastic syndrome developed a right optic neuropathy with optic disc edema and intractable periocular pain, one month after undergoing removal of a gangrenous gallbladder. Although results of a temporal artery biopsy were negative, he was treated with prednisone for presumed temporal arteritis. Attempts at tapering the prednisone dose led to recurrence of periocular pain. On neuro-ophthalmologic evaluation six months after the prednisone treatment was begun, he had developed right fourth and sixth cranial nerve palsies, and magnetic resonance imaging demonstrated a right orbital apex mass. Trans-sphenoidal biopsy revealed Aspergillus fumigatus. During treatment of aspergillosis, the patient developed a left hemiparesis. Magnetic resonance imaging disclosed multiple ring-enhancing cerebral masses. Biopsy revealed Nocardia asteroides. The patient was successfully treated for both infections with recovery of neurologic function except for the right optic neuropathy. Although immunocompromised patients are known to be subject to multiple infections, this may be the first reported case of concurrent sino-orbital aspergillosis and cerebral nocardiosis

We report an effective alternative treatment of profound chronic exposure keratopathy in a proptotic eye due to intraorbital extension of basal cell carcinoma. The corneal surface gradually reepithelialized in a 6-week period after the first application of Tegaderm transparent dressing (3M, St. Paul, MN, U.S.A.) with instillation of antibiotic ointment on the ocular surface. The patient has been comfortable with an intact epithelial surface, a vascularized cornea, and nonirritated surrounding skin after changing the Tegaderm dressing daily for 15 months. There was no evidence of recurrent corneal ulceration or infiltrations. We conclude that Tegaderm represents a useful treatment of exposure keratopathy due to chronic proptosis

BACKGROUND: Graves' orbitopathy can produce proptosis, compressive optic neuropathy, and extraocular motility abnormalities; symptoms result from an increase in orbital volume due to expansion of intraorbital fat, with or without extraocular muscle involvement. STUDY DESIGN: We conducted a chart review of patients who underwent orbital decompression to treat Graves' orbitopathy. Twenty-two orbits (13 patients) underwent orbital bone decompression, of which 17 orbits (9 patients) underwent the combined medial and lateral 'balanced' decompression. RESULTS: All patients had significant improvement with an average decrease in proptosis of 5.9 mm in the balanced decompression group. Restoration of normal optic nerve function was achieved in all patients with compressive optic neuropathy. Diplopia was noted in 4 patients (30.7%) preoperatively. Two patients had new postoperative diplopia (15.35%). CONCLUSION: In our experience, 'balanced' decompression results in a reduction of proptosis and improved optic nerve function and has a low incidence of complications
