CONTEXT The pathogenic basis for Graves' disease (GD) continues to elude our understanding. Specifically why activating antibodies are generated against self-antigens remains uncertain as does the identity of the antigen(s) that provokes orbital involvement in GD, a process known as thyroid-associated ophthalmopathy (TAO). OBJECTIVE The aim of the study(More)
PURPOSE Fibroblast diversity represents an emerging concept critical to our understanding of tissue inflammation, repair, and remodeling. Orbital fibroblasts heterogeneously display Thy-1 and exhibit unique phenotypic attributes that may explain the susceptibility of the human orbit to thyroid-associated ophthalmopathy (TAO). In the present study the(More)
Thyroid-stimulating hormone receptor (TSHR) plays a central role in regulating thyroid function and is targeted by IgGs in Graves' disease (GD-IgG). Whether TSHR is involved in the pathogenesis of thyroid-associated ophthalmopathy (TAO), the orbital manifestation of GD, remains uncertain. TSHR signaling overlaps with that of insulin-like grow factor 1(More)
Graves disease represents a systemic autoimmune process targeting the thyroid, orbit, and pretibial skin. The thyroid dysfunction is treatable, but no consistently effective medical therapy has yet been described for the orbital manifestations of Graves disease, also known as thyroid-associated ophthalmopathy or thyroid eye disease. Several autoantigens are(More)
PURPOSE To evaluate the clinical indications for orbital exenteration in a tertiary referral center and to compare clinicopathologic correlation and cosmetic outcome with previously reported data. DESIGN Retrospective, nonrandomized, consecutive case series. METHODS Review of Electronic Medical Record system, Orbital Clinic, Jules Stein Eye Institute,(More)
PURPOSE To describe a minimally invasive surgical technique using AlloDerm or dermis-fat grafts for lower eyelid retraction. METHODS A retrospective review of all patients undergoing lower eyelid retraction surgery via a minimal invasive, "en-glove" technique from 2005 through 2009. Charts were reviewed for the type of graft (AlloDerm or dermis-fat) used,(More)
Thyroid-associated ophthalmopathy (TAO) is a common yet poorly understood component of Graves' disease involving inflammation, congestion and soft tissue remodelling of the orbit. Unlike most autoimmune disorders, TAO has variable severity but follows a predictable course and is usually self-limited. The objective of this study was to investigate the(More)
The TSH receptor (TSHR) is the critical target for antibody production in Graves' disease (GD). Insulin-like growth factor 1 receptor (IGF1R) has been proposed as a second autoantigen in complications of GD such as orbitopathy. We attempted to induce orbital tissue remodeling in mice undergoing immunizations with plasmids encoding TSHR and IGF1R delivered(More)
CONTEXT The molecular basis for anatomically dispersed clinical manifestations in Graves' disease (GD) eludes our understanding. Bone marrow-derived, pluripotent fibrocytes represent a subset of peripheral blood mononuclear cells and infiltrate the orbital and thyroid tissues in GD. These cells may be involved in the pathogenesis of thyroid-associated(More)
PURPOSE Seprafilm is a hybrid product of carboxymethylcellulose and sodium hyaluronate that can act as an absorbable barrier to decrease the formation and severity of postoperative adhesions in abdominal, thoracic, and pelvic surgeries. The authors report their experience with use of Seprafilm in "trap door" orbital wall fracture repair. METHODS(More)
