Late orbital radiotherapy combined with intravenous methylprednisolone in the management of long-lasting active graves' orbitopathy: a case report and literature review. Endocrine 2024; 85:576-583. [PMID: 38517640 PMCID: PMC11291534 DOI: 10.1007/s12020-024-03788-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 03/15/2024] [Indexed: 03/24/2024]
Abstract
PURPOSE To present a case and review the literature on Orbital Radiotherapy (OR) combined with intravenous methylprednisolone, focusing on its late application in patients with long-lasting active Graves' Orbitopathy (GO). Additionally, we suggest emerging perspective for future research in this context. METHOD Relevant literature (randomized controlled studies, retrospective studies and reviews) was explored on PubMed from January 1973 to January 2024, searching "orbital radiotherapy" & "Graves disease". RESULTS OR is a well-established second-line treatment for moderate-to-severe active GO, providing response rates comparable to glucocorticoids. Its anti-inflammatory effect makes OR particularly suitable for early active GO, and when combined with glucocorticoids, outcomes are synergistically improved. The emergence of the new Volumetric Modulated Arc Image-Guided Radiation Therapy (VMAT-IGRT) technique enables precise radiation delivery to the target, significantly reducing associated toxicity. This technological advancement enhances the feasibility of radiotherapy in benign diseases like GO. A retrospective study indicated that late OR in patients with long-lasting active GO may improve diplopia and visual acuity, decreasing disease activity. Our case report supports this conclusion. CONCLUSIONS This report and literature review underscores the importance of considering late OR combined with intravenous methylprednisolone as a viable treatment option for GO patients with prolonged disease activity, emphasizing the crucial role of personalized therapy in managing GO. However, further investigations are warranted to validate this approach in cases of long-lasting active GO.

Abstract
Orbital radiotherapy for Graves' ophthalmopathy is an example of non-oncological radiotherapy. First introduced in the 1930s, this treatment has become widely used since the 1980s with several studies showing proof of both effectiveness and safety: a decrease of soft tissue involvement in 70 to 80% of patients and an improvement of ocular mobility in 30 to 80% of patients. Nowadays, it's one of the second line treatment options recognized by the European Group on Graves' orbitopathy in the management of a moderate to severe and active disease after failure of glucocorticoids. In that setting, orbital radiotherapy should be combined with glucocorticoids. To our knowledge, there are no practical recommendations on how orbital radiotherapy should be planned and conducted for Graves' ophthalmopathy. Optimal dose is not defined however the most frequent regimen consists of 20Gy in ten fractions of 2Gy, though other options may yield better results. Lastly, the use of modern technique of radiotherapy such as intensity-modulated radiation therapy may allow a better sparing of organs at risk compared to three-dimensional radiotherapy using lateral opposing fields.

Abstract
Thyroid-associated ophthalmopathy (TAO) is the most prevalent orbital disease in adults caused by an autoimmune disorder, which can lead to disfigurement and vision impairment. Developing effective treatments for this condition presents challenges due to our limited understanding of its underlying immune aberrations. In this study, we profiled the immune components in the peripheral blood of patients with TAO as well as healthy individuals, utilizing single-cell RNA sequencing and B-cell receptor repertoires (BCR) analysis. We observed a significant reduction in the proportions of regulatory B cells (Bregs) and type 2 conventional dendritic cells (DCs) in patients with TAO during the active phase. Conversely, there was a significant increase in the proportion of type 1 DCs. Further analysis of cell differentiation trajectory revealed potential impairment in the transition of B cells towards Breg phenotype during the active phase of TAO. Besides, the activation process of TAO appeared to involve inflammation and immune dysfunction, as indicated by the dynamic changes in the activities of key regulators. The abnormalities in the peripheral immune system, such as the reduced capacity of Bregs to suppress inflammation, were primarily driven by the enhanced interaction among Breg, DCs, and monocytes (i.e., CD22-PTPRC and BTLA-TNFRSF14). Collectively, our findings offer a comprehensive insight into the molecular regulation and cellular reconfiguration during the active phase of TAO at the single-cell level, in order to explore the pathogenesis of TAO and provide new ideas for the future treatment of TAO.

Abstract
Diagnosis and therapy of orbital diseases is an interdisciplinary challenge, in which i.e. otorhinolaryngologists, ophthalmologists, radiologists, radiation therapists, maxillo-facial surgeons, endocrinologists, and pediatricians are involved. This review article describes frequent diseases which both, otolaryngologists and ophthalmologists are concerned with in interdisciplinary settings. In particular the inflammatory diseases of the orbit including orbital complications, autoimmunological diseases of the orbit including Grave´s orbitopathy, and primary and secondary tumors of the orbit are discussed. Beside describing the clinical characteristics and diagnostic steps the article focusses on the interdisciplinary therapy. The review is completed by the presentation of most important surgical approaches to the orbit, their indications and possible complications. The authors tried to highlight the relevant facts despite the shortness of the text.

Abstract
Graves' orbitopathy is an autoimmune disease of the orbit that most frequently occurs with Graves' hyperthyroidism. The occurrence of autoantibodies directed against the TSH receptor (TRAb) is of central importance for the diagnosis and pathogenesis. These autoantibodies are mostly stimulating, and induce uncontrolled hyperthyroidism and tissue remodelling in the orbit and more or less pronounced inflammation. Consequently, patients suffer to a variable extent from periocular swelling, exophthalmos, and fibrosis of the eye muscles and thus restrictive motility impairment with double vision. In recent decades, therapeutic approaches have mainly comprised immunosuppressive treatments and antithyroid drug therapy for hyperthyroidism to inhibit thyroid hormone production. With the recognition that TRAb also activates an important growth factor receptor, IGF1R (insulin-like growth factor 1 receptor), biological agents have been developed. Teprotumumab (an inhibitory IGF1R antibody) has already been approved in the USA and the therapeutic effects are enormous, especially with regard to the reduction of exophthalmos. Side effects are to be considered, especially hyperglycaemia and hearing loss. It is not yet clear whether the autoimmune reaction (development of the TRAb/attraction of immunocompetent cells) is also influenced by anti-IGF1R inhibiting agents. Recurrences after therapy show that the inhibition of antibody development must be included in the therapeutic concept, especially in severe cases.

Abstract
PURPOSE The aim of our study was to assess the changes in the therapeutic response, ocular manifestations of GO and quality of life during the first year after OR. METHODS The study involved 26 consecutive patients with active moderate-to-severe GO indicated for OR, 18 females, mean age 57 ± 12.5. At baseline, all patients underwent comprehensive ocular examination and thyroid hormone and antibody testing. Then, OR was performed with a total dose of 20 Gy, divided into 10 sessions of 2 Gy each with concomitant oral intake of low-dose glucocorticoids. Therapeutic response and individual ocular manifestations were evaluated 1, 3, 6 and 12 months after OR, and QoL-at 3, 6 and 12 months by a disease-specific questionnaire. RESULTS One month after OR, 61.6% of patients had a therapeutic response (full or partial). During the follow-up, the proportion of full-responders gradually increased up to 57.5% at 12 months, while that of non-responders gradually decreased, reaching 11.5% at 12 months. All individual ocular manifestations improved significantly 1-3 months after OR. QoL related to visual functioning increased significantly at 6 months, whereas QoL related to appearance improved significantly at 12 months. CONCLUSIONS The vast majority of our patients with active moderate-to-severe GO exhibited full or partial therapeutic response after OR. The initial effect on the therapeutic response and individual ocular parameters was evident as soon as 1-3 months after the procedure. OR also has a beneficial effect on patients' QoL. TRIAL REGISTRATION NUMBER NCT05775185/07.03.2023, retrospectively registered.

Abstract
PURPOSE To quantify changes in extraocular muscle (EOM) cross-sectional areas (CSA) on orbital imaging in patients with thyroid eye disease before and after teprotumumab treatment, and assess for correlation with clinical outcomes. METHODS This retrospective study included thyroid eye disease patients treated with teprotumumab who had pre- and post-treatment CT imaging. Reformatted oblique coronal images were created for each orbit in a plane perpendicular to the optic nerve. EOM CSA measurements were performed by 2 radiographic reviewers and averaged. Primary outcomes included change in ratio of total EOM to orbit CSA, and of each individual muscle group to orbit CSA, before and after treatment. Secondary outcomes included subanalysis based on age (≥40, <40 years) and Clinical Activity Score (CAS) (≥4, <4), and comparison with clinical outcomes including CAS, Hertel exophthalmometry, Gorman diplopia score, and extraocular motility. RESULTS Forty-eight orbits of 24 patients (16 female, mean age 57.9 years) were included. There was a significant reduction in the total EOM to orbit CSA ratio ( p < 0.01) and for each individual rectus muscle to orbit CSA ratio ( p < 0.01 for all groups). Total EOM to orbit CSA ratios were reduced for 21 patients (87.5%); this was statistically significant in 13 patients (54.2%). There was significant improvement in CAS, proptosis, diplopia, and EOM motility ( p < 0.01 for all categories). There was a significant correlation between reduction of EOM CSA, and reduction of diplopia ( p < 0.01) and EOM motility ( p < 0.01). CONCLUSIONS EOM CSA is significantly reduced following treatment with teprotumumab, and correlates with clinical findings including improvement in extraocular motility and diplopia.

Abstract
PURPOSE To report the therapeutic efficacy of intravenous methylprednisolone (IVMP) in patients with restrictive myopathy caused by thyroid eye disease (TED). METHODS The present prospective uncontrolled study comprised 28 patients with TED and restrictive myopathy who presented with diplopia that had developed within 6 months before their visit. All patients were treated with IVMP for 12 weeks. Deviation angle, limitation of extraocular muscle (EOM) movement, binocular single vision score, Hess score, clinical activity score (CAS), modified NOSPECS score, exophthalmometric value, and the size of EOMs on computed tomography were evaluated. The patients were divided into two groups: those whose deviation angle had decreased or remained unchanged 6 months after treatment (group 1; n = 17) and those whose deviation angle had increased in that time (group 2; n = 11). RESULTS The mean CAS of the whole cohort significantly decreased from baseline to 1 month and 3 months after treatment (P = 0.03 and P = 0.02, respectively). The mean deviation angle significantly increased from baseline to 1, 3, and 6 months (P = 0.01, P < 0.01, and P < 0.01, respectively). The deviation angle decreased in 10 (36%), remained constant in seven (25%), and increased in 11 (39%) of the 28 patients. When groups 1 and 2 were compared, no single variable was identified as a cause of deviation angle deterioration (P > 0.05). CONCLUSIONS When treating patients with TED who have restrictive myopathy, physicians should be aware that some patients show worsening of the strabismus angle despite inflammation control with IVMP therapy. Uncontrolled fibrosis can result in motility deterioration.

Abstract
PURPOSE Dysthyroid optic neuropathy (DON) is a rare sight-threatening complication of Graves' disease. First-line treatment for DON consists of high-dose intravenous methylprednisolone (ivMP), followed by immediate orbital decompression (OD) if the response is poor or absent as recommended by the 2021 European Group on Graves' orbitopathy guidelines. The safety and efficacy of the proposed therapy have been proven. However, consensus regarding possible therapeutic options for patients with contraindications to ivMP/OD or resistant form of disease is missing. This paper aims to provide and summarize all available data regarding possible alternative treatment strategies for DON. METHODS A comprehensive literature search within an electronic database was performed including data published until December 2022. RESULTS Overall, 52 articles describing use of emerging therapeutic strategies for DON were identified. Collected evidence indicates that biologics, including teprotumumab and tocilizumab, may be considered as an important possible treatment option for DON patients. Rituximab should be avoided in DON due to conflicting data and risk of adverse events. Orbital radiotherapy could be beneficial for patients with restricted ocular motility classified as poor surgical candidates. CONCLUSION Only a limited number of studies have been dedicated to the therapy of DON, mostly retrospective with a small sample size. Clear criteria regarding diagnosis and resolution of DON do not exist, which restricts comparison of therapeutic outcomes. Randomized clinical trials and comparison studies with long-term follow-ups are necessary to verify the safety and efficacy of each therapeutic option for DON.

Abstract
Graves' orbitopathy (GO) is an orbital autoimmune disorder and the main extrathyroidal manifestation of Graves' disease, the most common cause of hyperthyroidism. GO affects about 30% of Graves' patients, although fewer than 10% have severe forms requiring immunosuppressive treatments. Management of GO requires a multidisciplinary approach. Medical therapies for active moderate-to-severe forms of GO (traditionally, high-dose glucocorticoids) often provide unsatisfactory results, and subsequently surgeries are often needed to cure residual manifestations. The aim of this review is to provide an updated overview of current concepts regarding the epidemiology, pathogenesis, assessment, and treatment of GO, and to present emerging targeted therapies and therapeutic perspectives. Original articles, clinical trials, systematic reviews, and meta-analyses from 1980 to 2021 were searched using the following terms: Graves' disease, Graves' orbitopathy, thyroid eye disease, glucocorticoids, orbital radiotherapy, rituximab, cyclosporine, azathioprine, teprotumumab, TSH-receptor antibody, smoking, hyperthyroidism, hypothyroidism, thyroidectomy, radioactive iodine, and antithyroid drugs. Recent studies suggest a secular trend toward a milder phenotype of GO. Standardized assessment at a thyroid eye clinic allows for a better general management plan. Treatment of active moderate-to-severe forms of GO still relies in most cases on high-dose systemic-mainly intravenous-glucocorticoids as monotherapy or in combination with other therapies-such as mycophenolate, cyclosporine, azathioprine, or orbital radiotherapy-but novel biological agents-including teprotumumab, rituximab, and tocilizumab-have achieved encouraging results.

Abstract
Objective To evaluate the safety and effectiveness of hypofractionated orbital radiotherapy applied in the treatment of thyroid-associated ophthalmopathy (TAO) patients. Methods Between 2014 and 2018, we retrospectively reviewed the cases of 28 patients with TAO. All patients underwent radiotherapy on both retroocular tissues and received an oral steroid. Patients were divided into two treatment groups: 14 patients received conventional fractionated radiotherapy (20 Gy in 10 fractions), and the second group of 14 patients received hypofractionated radiotherapy (20 Gy in five fractions). The clinical activity score (CAS), NOSPECS (No physical signs or symptoms, Only signs, Soft tissue involvement, Proptosis, Extraocular muscle signs, Corneal involvement, and Sight loss) classification, Hess screen test and binocular single vision (BSV) were evaluated to determine the response to treatment before and at 1 month after radiotherapy. Results There were no significant differences in any of the variables between the two treatment groups. In both groups, the CAS and NOSPECS score decreased significantly, and the range of extraocular muscle motility in Hess screen test and BSV improved significantly after radiotherapy (p < 0.05). There were no significant differences in CAS, NOSPECS score, Hess screen test or BSV between the two groups. No radiation-related, acute severe toxicity was observed. Conclusion Hypofractionated radiotherapy for TAO produced a comparable clinical outcome to that of conventional fractionated radiotherapy. Further case accumulation and long-term follow-up are required to determine if late toxicity occurs and to confirm efficacy. Advances in knowledge This is the first study to show that the efficacy and risk of adverse events are comparable between hypofractionated radiotherapy and conventional radiotherapy in the treatment of TAO.

Choi JH, Lee JK. Efficacy of orbital radiotherapy in moderate-to-severe active graves' orbitopathy including long-lasting disease: a retrospective analysis. Radiat Oncol 2020; 15:220. [PMID: 32958019 PMCID: PMC7507623 DOI: 10.1186/s13014-020-01663-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 09/09/2020] [Indexed: 12/12/2022] Open
Abstract
Background We aimed to explore the efficacy of orbital radiotherapy (RT) in patients with moderate-to-severe active Graves’ orbitopathy (GO), including long-lasting disease, and to determine the predictive factors associated with treatment response. Methods This was a retrospective study of 62 moderate-to-severe active GO patients treated with RT. Demographic data and ophthalmic findings prior to RT and at 3 and 6 months afterward were analyzed. Computed tomography was performed before and after RT to compare orbital volume change. We used logistic regression to determine the predictive factors for treatment response. Subjects were divided into early- and late-active phase groups based on GO duration of 24 months and treatment outcomes were compared with each other to observe the effects of RT timing on treatment response. Results Forty (64.5%) and forty-six (74.1%) patients experienced improvements in GO at 3 and 6 months after radiotherapy, respectively. Ocular parameters such as clinical activity score (CAS), proptosis, extraocular muscle (EOM) limitation, and compressive optic neuropathy (CON) were improved by RT. Volumes of EOM significantly decreased after RT. The enlargement of EOMs and EOM limitation were predictive factors for a good response to RT. At 6 months after RT, 22 (68.8%) patients of late-active phase group exhibited improvement in GO, which is comparable to the number of 24 (80.0%) patients of early-active phase group. In the late-active phase group, CAS, diplopia, and visual acuity were improved significantly, but there was no change in EOM limitation. Conclusions In moderate-to-severe active GO patients, orbital RT may help improve high CAS, proptosis, EOM limitation, and CON. The orbital RT in long-lasting active GO patients may be considered as treatments for the relief of symptoms including high CAS and poor visual acuity.

Abstract
INTRODUCTION Thyroid-associated ophthalmopathy (TAO) is a disfiguring, potentially blinding, and sub-optimally managed autoimmune condition. Current therapy of active TAO consists most frequently of glucocorticoid steroids, orbital radiation, or B-cell depletion; all of which are associated with substantial side effects. Teprotumumab (Tepezza) is a human monoclonal antibody against the insulin-like growth factor type I receptor (IGF-IR), recently evaluated in two clinical trials for active moderate-to-severe TAO that was recently approved by the United States Food and Drug Administration (FDA) for use in TAO. AREAS COVERED This article reviews phase II and III placebo-controlled, double-masked, prospective, multicenter studies assessing the efficacy and safety of teprotumumab for the treatment of active, moderate-to-severe TAO. EXPERT OPINION Teprotumumab has demonstrated substantial and rapid improvement in Clinical Activity Score and proptosis reduction in TAO compared to placebo. Subjective diplopia and quality of life were also improved in both clinical trials. Teprotumumab exhibited a favorable safety profile, with transient hyperglycemia, muscle cramps, and auditory side effects being associated with the drug; these were usually transient. The trial findings indicate that teprotumumab is a promising, potential first-line therapy for treating TAO.

Abstract
Purpose To evaluate the effect of orbital steroid injections in patients with active thyroid ophthalmopathy resistant to or dependent on systemic steroids, or with complications related to systemic steroid use. Methods This prospective non-comparative case series includes 31 eyes of 17 patients with active thyroid ophthalmopathy and clinical activity score (CAS) of 3 or more, without compressive optic neuropathy or overt exposure keratopathy. All subjects had a history of previous systemic steroid use (with steroid resistance or dependence) or had developed complications related to steroids. A combination of steroids including triamcinolone acetonide 20 mg and dexamethasone 4 mg was injected in the upper and lower retroseptal orbital spaces three or four times at one-month intervals. The patients were examined periodically after each injection and at least three months after the last injection. Results Mean pre-injection CAS was 5.2 ± 1.3 which was improved to 1.6 ± 1 after the fourth injection (P< 0.001). Upper and lower lid retraction improved in 100% and 68.2% of the affected eyes, respectively. Strabismus completely resolved in one of five affected patients and the most significant improvement was observed in supraduction. Mean improvement in exophthalmos was 1.2 ± 1.1 mm. Visual acuity did not significantly change after the injections. Eyelid ecchymosis and/or subconjunctival hemorrhage was observed in 7.1% and intraocular pressure rise occurred in 8.8% of eyes. Conclusion Orbital steroid injections can be used for the treatment of active thyroid ophthalmopathy when the patient is resistant to or dependent on systemic steroids or has developed complications of systemic steroids.

Abstract
Background Accurate measurement and reconstruction of orbital soft tissue is important to diagnosis and treatment of orbital diseases. This study applied an interactive graph cut method to orbital soft tissue precise segmentation and calculation in computerized tomography (CT) images, and to estimate its application in orbital reconstruction. Methods The interactive graph cut method was introduced to segment extraocular muscle and intraorbital fat in CT images. Intra- and inter-observer variability of tissue volume measured by graph cut segmentation was validated. Accuracy and reliability of the method was accessed by comparing with manual delineation and commercial medical image software. Intraorbital structure of 10 patients after enucleation surgery was reconstructed based on graph cut segmentation and soft tissue volume were compared within two different surgical techniques. Results Both muscle and fat tissue segmentation results of graph cut method showed good consistency with ground truth in phantom data. There were no significant differences in muscle calculations between observers or segmental methods (p > 0.05). Graph cut results of fat tissue had coincidental variable trend with ground truth which could identify 0.1cm3 variation. The mean performance time of graph cut segmentation was significantly shorter than manual delineation and commercial software (p < 0.001). Jaccard similarity and Dice coefficient of graph cut method were 0.767 ± 0.045 and 0.836 ± 0.032 for human normal extraocular muscle segmentation. The measurements of fat tissue were significantly better in graph cut than those in commercial software (p < 0.05). Orbital soft tissue volume was decreased in post-enucleation orbit than that in normal orbit (p < 0.05). Conclusion The graph cut method was validated to have good accuracy, reliability and efficiency in orbit soft tissue segmentation. It could discern minor volume changes of soft tissue. The interactive segmenting technique would be a valuable tool for dynamic analysis and prediction of therapeutic effect and orbital reconstruction.

Abstract
Thyroid-associated ophthalmopathy (TAO) is a complex disease process presumed to emerge from autoimmunity occurring in the thyroid gland, most frequently in Graves disease (GD). It is disfiguring and potentially blinding, culminating in orbital tissue remodeling and disruption of function of structures adjacent to the eye. There are currently no medical therapies proven capable of altering the clinical outcome of TAO in randomized, placebo-controlled multicenter trials. The orbital fibroblast represents the central target for immune reactivity. Recent identification of fibroblasts that putatively originate in the bone marrow as monocyte progenitors provides a plausible explanation for why antigens, the expressions of which were once considered restricted to the thyroid, are detected in the TAO orbit. These cells, known as fibrocytes, express relatively high levels of functional TSH receptor (TSHR) through which they can be activated by TSH and the GD-specific pathogenic antibodies that underpin thyroid overactivity. Fibrocytes also express insulin-like growth factor I receptor (IGF-IR) with which TSHR forms a physical and functional signaling complex. Notably, inhibition of IGF-IR activity results in the attenuation of signaling initiated at either receptor. Some studies suggest that IGF-IR-activating antibodies are generated in GD, whereas others refute this concept. These observations served as the rationale for implementing a recently completed therapeutic trial of teprotumumab, a monoclonal inhibitory antibody targeting IGF-IR in TAO. Results of that trial in active, moderate to severe disease revealed dramatic and rapid reductions in disease activity and severity. The targeting of IGF-IR with specific biologic agents may represent a paradigm shift in the therapy of TAO.

Abstract
BACKGROUND Orbital radiotherapy (RT) is an effective and consolidate treatment for steroid-refractory Graves' ophthalmopathy (GO); however, long term effects are not well known. OBJECTIVES The aim of this study was to evaluate the long term efficacy and toxicity of orbital RT plus concomitant systemic steroids in a population of patients with moderate-to-severe GO or with eyesight threatening symptoms refractory to steroids. METHODS Forty patients with moderate-to-severe GO or with eyesight threatening symptoms not responsive/resistant to steroids were treated with orbital RT at the dose of 20 Gy in 10 fractions plus concomitant steroids. Clinical activity score (CAS) and symptoms status were evaluated to determine response to the treatment. RESULTS We reported overall improvement of symptoms, in particular, a regression at 1-year of diplopia in 32.5% eye movement impairment in 42.5%, eyesight in 27.5% and a 2 point reduction in CAS. After a median time of 56 months 21.9% of the patients underwent orbital decompression for relapse of GO, 4.8% received surgical correction of strabismus, and 2.4% received eyelid lipectomy. Acute toxicity was mild; grade 1 - 2 keratitis occurred in 19.5% of the patients and grade 3 keratitis was observed in 2.4% of the patients. Cataract occurred in 7.4% of the patients after a median time of 24-month-follow-up. No secondary malignancies were reported. CONCLUSIONS Our results reported the long-term efficacy and the good tolerance of orbital RT. The combination of RT plus steroids in this setting may avoid or delay performing the surgery in some cases.

Abstract
PURPOSE To critically review the published literature on orbital radiotherapy as a treatment modality for thyroid eye disease (TED). METHODS A systematic review and analysis of the relevant published literature was performed. RESULTS Thyroid eye disease is an autoimmune condition that is amenable to treatments that modulate the immune response, including orbital radiotherapy (ORT). Ideal candidates for ORT are patients in the early, active phase of TED with moderate to severe, or rapidly progressive, disease, including patients with significant motility deficits and compressive optic neuropathy. Patients with progressive strabismus may also benefit. Patients with mild or inactive disease will not benefit from ORT when compared with the natural history of the disease. Orbital radiotherapy should generally be used in conjunction with corticosteroid therapy, with response to corticosteroids demonstrating the immunomodulatory therapeutic potential of ORT. When treating TED-compressive optic neuropathy, ORT may help obviate the need for urgent surgical decompression, or postpone it until the stable, inactive phase of the disease. Orbital radiotherapy treatment doses should approach 20 Gy in most cases, but lower doses may be considered in younger patients without significant dysmotility. The safety profile of ORT is well established, and side effects are minimal in appropriately selected patients. CONCLUSIONS Radiotherapy is a safe and effective treatment for active TED in appropriately selected patients.

Abstract
Thyroid-associated ophthalmopathy (TAO), the ocular manifestation of Graves' disease, is a process in which orbital connective tissues and extraocular muscles undergo inflammation and remodeling. The condition seems to result from autoimmune responses to antigens shared by the thyroid and orbit. The thyrotropin receptor (TSHR), expressed at low levels in orbital tissues, is a leading candidate antigen. Recent evidence suggests that another protein, the insulin-like growth factor-I receptor (IGF-IR), is overexpressed in TAO, and antibodies against IGF-IR have been detected in patients with the disease. Furthermore, TSHR and IGF-IR form a physical and functional complex, and signaling initiated at TSHR requires IGF-IR activity. Identification of therapy for this rare disease has proven challenging and currently relies on nonspecific and inadequate agents, thus representing an important unmet need. A recently completed therapeutic trial suggests that inhibiting IGF-IR activity with a monoclonal antibody may be an effective and safe treatment for active TAO.

Abstract
BACKGROUND Thyroid eye disease (TED) is a debilitating autoimmune orbital disease that is often a result of Graves' disease. Dysthyroid optic neuropathy (DON) is a rare but sight-threatening manifestation of TED with therapeutic challenges that can potentially lead to visual loss. CASE PRESENTATION A 74-year-old man experienced active TED with extremely severe redness and swelling of the conjunctiva, loss of visual acuity and exacerbation of disfiguring proptosis. Computed tomography revealed the involvement of extraocular muscles resulting in optic nerve compression. He was in poor general condition and was intolerant to steroids. To achieve the optimal operating conditions for orbital decompression surgery, the patient was initially treated with orbital radiotherapy. The patient responded well, with improvements in clinical activity score and visual acuity. CONCLUSION This case demonstrates a rare and severe case of DON with therapeutic challenges. To date, no cases has been reported of a patient with such severe and unusual ocular manifestations. Early awareness of the occurrence of optic nerve compression and prompt treatment are important to prevent irreversible outcomes. Orbital radiotherapy should be considered as a useful surgery-delaying alternative for DON, especially in patients who have contraindications to steroids.

Abstract
The aim of this study was to evaluate and compare the efficacy of intravenous (iv) glucocorticoids (GCs) with and without orbital radiotherapy (ORT) in a retrospective analysis of patients with active, moderate-to-severe Graves' orbitopathy (GO). Since diplopia has the strongest impact on quality of life, a careful work up of motility and binocular single vision (BSV) has been performed. The Essen-EUGOGO-Center database (n=3655) was screened for patients with untreated moderate-to-severe, active GO, onset ≤12 months. The inclusion criteria were met by 148 patients (n=76 ivGC, n=72 ivGC + ORT). We analyzed CAS (inactivation: ≤2), NOSPECS, lid-width, proptosis, motility, and field of BSV. To score the overall ophthalmic outcome, a severity-weighted-score (SOS) was compared with an established EUGOGO inflammation-weighted-score (IOS). Cumulative ivGCs dosages and duration of GO did not differ between the groups. Patients with combination therapy had a significantly more severe GO at baseline. Therefore, a subgroup with matched severity was additionally compared. In the IOS, both groups reached similar improvement rates (55.2 vs. 63.9%; p=0.31). However, in the SOS, the rates differed significantly (46.1 vs. 61.1%; p=0.03- unmatched and p=0.03 matched), despite similar rates of inactivation (65.8 vs. 63.8%). Impaired motility improved significantly more often after combination therapy (p=0.01 matched, p=0.004 unmatched). Treatment responders showed only partial improvement (proptosis: 2.5±0.5 mm; motility: 11.3±10.9°). In our retrospective analysis, combination therapy (ivGCs + ORT) was significantly more effective in reduction of severity and should therefore always be considered in moderate-to-severe GO stages, especially in the presence of motility disorders. However, the limited improvement in clinical parameters, despite the promising effect on inactivation of inflammation, has to be outlined to the patients.

Abstract
Thyroid-associated orbitopathy (TAO) is an inflammatory autoimmune disorder. The most serious complication of TAO is dysthyroid optic neuropathy (DON), which can lead to permanent vision loss because of volume expansion in the orbital apex. Orbital radiation therapy (ORT) is an anti-inflammatory treatment used in the treatment of active TAO. Clinical studies support radiotherapy as having a modest effect on DON, and early radiotherapy may protect against disease progression to DON. Current studies suggest that radiotherapy is generally safe. However, risks still exist in some cases. The possible effects of radiotherapy on TAO, especially complicated with DON, are reviewed. The effects of radiotherapy on DON are not completely known, and evidence from standardized, prospective, and multicenter clinical trials is still lacking.

Abstract
INTRODUCTION Dysthyroid optic neuropathy (DON) is a severe manifestation of thyroid eye disease (TED) that can result in permanent vision loss. Management is complex, multidisciplinary, and involves medical and/or surgical therapies. This review describes current concepts in the epidemiology, pathophysiology, diagnosis, and treatment of DON. AREAS COVERED An extensive review of the literature was performed to detail current concepts on the diagnosis and management of DON. This includes utilization of various medical and surgical modalities for disease management. EXPERT COMMENTARY DON can result in permanent blindness and often requires the use of corticosteroids and surgical decompression. We favor the use of intravenous corticosteroids and a transcaruncular approach when surgical decompression is indicated. The use of orbital radiation for DON is often reserved for patients that are poor surgical candidates and/or patients with refractory disease.

Abstract
Purpose To characterize the relationship between inflammation and swelling of extraocular muscles in thyroid-associated ophthalmopathy before and after methylprednisolone pulse therapy. Methods The signal intensities and volumes of the superior rectus (SR), inferior rectus (IR), lateral rectus (LR), medial rectus (MR), and superior oblique (SO) muscles were measured with magnetic resonance imaging in 25 eyes of 25 patients with thyroid-associated ophthalmopathy in the acute inflammatory phase before and after methylprednisolone pulse therapy. The signal intensity ratios (SIRs) of muscles and brain white matter were calculated. Result The mean SIRs before treatment were 2.28±0.74 in SR, 2.66±0.57 in IR, 2.03±0.42 in LR, 2.45±0.49 in MR, and 1.98±0.48 in SO muscles. The mean SIRs after treatment were 1.82±0.62, 1.84±0.52, 1.70±0.35, 1.95±0.46, and 1.60±0.36, respectively. The mean volumes (cm3) before treatment were 1.35±0.67 in SR, 1.21±0.39 in IR, 0.66±0.13 in LR, 0.94±0.31 in MR, and 0.58±0.14 in SO muscles. Those after treatment were 1.12±0.45, 0.91±0.31, 0.61±0.12, 0.85±0.28, and 0.49±0.11, respectively. The SIRs showed significantly positive correlations with volumes both before and after treatment in SR muscles (before, r=0.77; after, r=0.69), IR muscles (before, r=0.65; after, r=0.60), MR muscles (before, r=0.69; after, r=0.73), and SO muscles (before, r=0.52; after, r=0.50) (P<0.01 for all correlations). Conclusion Swelling reflected the inflammation in extraocular muscles of thyroid-associated ophthalmopathy both before and after treatment.
