Abstract
PURPOSE Review the historical context of research and changing therapeutic landscape of thyroid-associated ophthalmopathy (TAO) by focusing on the relationship between TAO, CD34+ fibrocytes, thyrotropin receptor (TSHR), and insulin-like growth factor-I receptor (IGF-IR). METHODS A literature review using search terms, including fibrocytes, IGF-IR, TSHR, TAO, and thyroid eye disease. RESULTS The mechanisms involved in TAO have been partially identified. Substantial progress has been made over several decades, including 1) recognizing the interplay between the professional immune system and orbital tissues; 2) TSHR and IGF-IR act interdependently in mediating the pathogenesis of TAO; 3) Multiple cytokines and specific immune cells are involved in activating and remodeling orbital tissue; 4) Recognition of these mechanisms is allowing the development of target therapies such as teprotumumab, a monoclonal antibody IGF-IR inhibitor approved by the US Food and drug administration for treatment of TAO; and 5) It appears that teprotumumab acts on the systemic immune system peripheral to the orbit. CONCLUSION Additional molecules targeting IGF-IR and other plausible disease mechanisms are currently under development. This activity in the TAO therapeutic space portends even greater improvements in patient care.

Abstract
Importance Thyroid eye disease (TED) results in varying degrees of proptosis and diplopia negatively affecting quality of life (QoL), producing possibly substantial visual changes, disfigurement, and disability. Objective To determine the association of varying TED severities with QoL in a non-TED population by assessing health state utility scores. Design, Setting, and Participants This qualitative study, conducted from April 20, 2020, to April 29, 2021, assessed health states for active, moderate-severe TED, and values were elicited using time trade-off methods. Six health states of varying severity were determined from 2 placebo-controlled clinical trials (171 patients with TED and clinical activity score ≥4, ±diplopia/proptosis) and refined using interviews with US patients with TED (n = 6). Each health state description was validated by interviews with additional TED patient advocates (n = 3) and physician experts (n = 3). Health state descriptions and a QOL questionnaire were piloted and administered to a general population. Visual analog scales (VASs) were also administered to detect concurrence of the findings. Main Outcomes and Measures TED health state utility scores and whether they differ from one another were assessed using Shapiro-Wilk, Kruskal-Wallis, pairwise Wilcoxon rank sum, and paired t tests. Results A total of 111 participants completed time trade-off interviews. The mean (SD) utility value was 0.44 (0.34). The lowest (worse) mean utility value was observed in the most severe disease state (constant diplopia/large proptosis) with 0.30 (95% CI, 0.24-0.36), followed by constant diplopia/small proptosis (0.34; 95% CI, 0.29-0.40), intermittent or inconstant diplopia/large proptosis (0.43; 95% CI, 0.36-0.49), no diplopia/large proptosis (0.46; 95% CI, 0.40-0.52), and intermittent or inconstant diplopia/small proptosis (0.52; 95% CI, 0.45-0.58). The highest (best) mean value, 0.60 (95% CI, 0.54-0.67), was observed for the least severe disease state (no diplopia/small proptosis). Conclusions and Relevance These findings suggest that patients with active, moderate-severe TED may have substantial disutility, with increasing severity of proptosis/diplopia more likely to have detrimental associations with QoL. These health state scores may provide a baseline for determining QoL improvement in these TED health states (utility gains) treated with new therapies.

Abstract
Thyroid eye disease (TED) remains challenging for clinicians to evaluate and manage. Novel therapies have recently emerged, and their specific roles are still being determined. Most patients with TED develop eye manifestations while being treated for hyperthyroidism and under the care of endocrinologists. Endocrinologists, therefore, have a key role in diagnosis, initial management, and selection of patients who require referral to specialist care. Given that the need for guidance to endocrinologists charged with meeting the needs of patients with TED transcends national borders, and to maximize an international exchange of knowledge and practices, the American Thyroid Association and European Thyroid Association joined forces to produce this consensus statement.

Abstract
Background: The thyroid eye disease (TED) treatment landscape is rapidly evolving. How new treatment options have impacted practice is unknown. Methods: We conducted a cross-sectional electronic survey of American and European Thyroid Association members between June 2 and June 30, 2021. The survey included TED questions about resources for its management, index cases for different severities and presentations of TED, barriers for the management of TED, and participants' concerns about TED. We classified respondents into three geographic categories: North America, Europe, or other regions. Results: Two hundred fifty-two eligible participants started the survey (15% response rate), and 227 completed it. Participants were mostly men (50.2%, 114/227), white (79.7%, 181/227), endocrinologists with a thyroid focus (66.1%, 150/227), practicing in a tertiary academic center (46.7%, 106/227), caring for 10 or more TED patients over the last 12 months (40.5%, 92/227), and reported not having a multidisciplinary TED clinic in their institution (52.8%, 120/227). The majority reported that new TED cases per annum have not changed in the past 10 years (47.5%, 108/227), and that TED patients are found in practice during the management of hyperthyroidism (41.8%, 95/227). For mild active TED, participants from Europe reported a higher use of selenium (73%[96/132] vs. 32%[20/62] of respondents from North America and 24%[8/33] of respondents from other regions). For moderate-to-severe active TED, there was a modest preference for teprotumumab as first-line therapy (37%, 23/62) among North American participants and intravenous (IV) steroids (73%[96/132], and 42%[14/33]) for participants from Europe and other regions, respectively. These treatment preferences did not change in patients with moderate-to-severe active TED with poorly controlled diabetes. In contrast, participants from the three geographic categories preferred IV steroids for optic neuropathy and women planning pregnancy. The three top "very important" concerns about TED management according to participants were: the cost of TED treatment (31.3%, 71/227), lack of effective TED treatments (19.8%, 45/227), and difficulty in predicting whether TED will develop (18.9%, 43/227). Conclusions: There is a marked geographic practice variation in the management of TED. Clinicians' concerns about TED management demand ongoing research on more effective treatment, TED predictive tools, and policy changes to improve the affordability of new TED therapies.
