ABSTRACT
ABSTRACT Orbital decompression is widely performed for the management of proptosis for cosmetic and functional cases of Graves orbitopathy. The main side effects include dry eye, diplopia, and numbness. Blindness after orbital decompression is extremely rare. The mechanisms of vision loss after decompression are not well described in the literature. Considering the devastating effect and rarity of this complication, this study presented two cases of blindness after orbital decompression. In both cases, vision loss was provoked by slight bleeding in the orbital apex.
RESUMO A descompressão orbitária é uma cirurgia amplamente empregada para correção da proptose em casos cosméticos e funcionais da orbitopatia de Graves. Os principais efeitos colaterais induzidos pela descompressão são olho seco, diplopia e parestesias. Amaurose pós descompressão é uma complicação extremamente rara e cujos mecanismos são pouco discutidos na literatura. Considerando o efeito devastador representado pela perda visual e a escassez de relatos dessa complicação, os autores apresentam dois relatos de amaurose após descompressão orbitária. Nos dois casos a perda visual ocorreu devido a sangramento de pequena monta no ápice orbitário.
ABSTRACT
El hipertiroidismo es un trastorno caracterizado por el exceso de hormonas tiroideas. El déficit de yodo es un factor clave en dicha patología y en lugares con suficiencia del mismo se asocian a au-toinmunidad tiroidea. La prevalencia de hipertiroidismo mani-fiesto varía del 0,2% al 1,3% en áreas con suficiencia de yodo, sin embargo, esto puede variar en cada país por diferencias en umbrales de diagnóstico, sensibilidad de ensayo y población se-leccionada. Un reporte de The Third National Health and Nutri-tion Examination Survey (NHANES III) mostró que el hiperti-roidismo manifiesto se presenta en 0,7% de la población general e hipertiroidismo subclínico en el 1,7%1,2.En incidencia, la patología se asocia con la suplementación de yodo, con la mayor frecuencia en áreas de deficiencias, por au-mento de nódulos tiroideos en la población anciana, teniendo a regiones de áreas montañosas como América del Sur, África Central y suroeste de Asia dentro de este grupo. Un meta aná-lisis de estudios europeos mostró una incidencia general de 50 casos por 100000 personas/años1. En Ecuador, según los datos del Instituto Nacional de Estadísticas y Censos (INEC) del 2017, se reportaron 157 casos de hipertiroidismo, de los cuales la En-fermedad de Graves (EG) fue la causa más común, seguida por el bocio multinodular tóxico (BMNT) y finalmente el adenoma tóxico (AT) con una incidencia de 61 %, 24 % y 14 % respecti-vamente3.Los pacientes con esta patología tienen aumento de riesgo com-plicaciones cardiovasculares y mortalidad por todas las causas, siendo falla cardíaca uno de sus principales desenlaces, así el diagnóstico precoz evita estos eventos, principalmente en pobla-ción de edad avanzada.El presente protocolo se ha realizado para un correcto trata-miento de esta patología en el Hospital de Especialidades Carlos Andrade Marín (HECAM).
Hyperthyroidism is a disorder characterized by an excess of thyroid hormones. Iodine deficiency is a key factor in this pa-thology and in places with iodine deficiency it is associated with thyroid autoimmunity. The prevalence of overt hyperthyroidism varies from 0,2% to 1,3% in iodine-sufficient areas; however, this may vary from country to country due to differences in diag-nostic thresholds, assay sensitivity, and selected population. A report from The Third National Health and Nutrition Examina-tion Survey (NHANES III) showed that overt hyperthyroidism occurs in 0,7% of the general population and subclinical hyper-thyroidism in 1,7%1,2.In incidence, the pathology is associated with iodine supplemen-tation, with the highest frequency in areas of deficiencies, due to increased thyroid nodules in the elderly population, having regions of mountainous areas such as South America, Central Africa and Southwest Asia within this group. A meta-analysis of European studies showed an overall incidence of 50 cases per 100000 person/years1. In Ecuador, according to data from the National Institute of Statistics and Census (INEC) in 2017, 157 cases of hyperthyroidism were reported, of which, Graves' di-sease (GD) was the most common cause, followed by toxic mul-tinodular goiter (BMNT) and finally toxic adenoma (TA) with an incidence of 61 %, 24 % and 14 % respectively3.Patients with this pathology have an increased risk of cardiovas-cular complications and all-cause mortality, with heart failure being one of the main outcomes, so early diagnosis avoids these events, mainly in the elderly population.The present protocol has been carried out for the correct treat-ment of this pathology at the Carlos Andrade Marín Specialties Hospital (HECAM).

ABSTRACT
AIM: To evaluate the lacrimal gland parameters and their correlation with clinical examination in patients with thyroid-associated ophthalmopathy(TAO)using orbital magnetic resonance imaging(MRI).METHODS: A total of 38 patients(76 eyes)with TAO were selected as case group, and 26 patients(52 eyes)who matched the gender and age with case group and volunteered to accept examination were selected as normal control group. Patients in case group were categorized into active TAO group and inactive TAO group according to the modified clinical activity score(CAS). The exophthalmos was evaluated on T1WI after obtaining the MRI images, the longest lacrimal gland length, width, and the biggest area in axial and coronal images were evaluated on T2WI, and the maximum T2 value and mean T2 value of the lacrimal gland were recorded.RESULTS: There were no significant differences in age, gender and exophthalmos between active TAO and inactive TAO(P>0.05). The area of lacrimal gland was higher in active TAO than that in inactive TAO, and was higher in inactive TAO than that in control group in coronal and axial section(all P<0.01). The length of lacrimal gland in coronal and axial section was higher in the active TAO than that in the inactive TAO and the control group(all P<0.05). The width of lacrimal gland in coronal and axial section was higher in active TAO and inactive TAO than that in the control group(all P<0.05). The maximum T2 value in the active TAO was higher than that in the inactive TAO and control group, and the inactive TAO was higher than that in the control group(all P<0.05). The average T2 value in the active TAO was higher than that in the inactive TAO and control group(all P<0.05). CAS was positively correlated with lacrimal gland area in axial, coronal section and maximum T2 value(all P<0.01).CONCLUSION: The lacrimal gland is significantly enlarged in patients with TAO, especially in active TAO. The lacrimal gland area in axial, coronal section and maximum T2 value could be potentially utilized as valuable radiographic biomarkers for the activity of TAO.
ABSTRACT
Teprotumumab-trbw,a monoclonal antibody that acts on the insulin growth factor-Ⅰ receptor, was approved in 2020 for the treatment of thyroid-associated ophthalmopathy, but little is known about it in China. It is hoped to provide guidance for clinical use through the review of its molecular structure, pharmacokinetics, therapeutic mechanism, clinical research and safety. It inhibits immune inflammation by blocking thyroid-stimulating hormone receptor /insulin growth factor-Ⅰ receptor crosstalk signaling, so as to reduce the production of hyaluronic acid and inflammatory factors in response. It can also promote the apoptosis of retro-orbital fibroblasts/adipocytes and inhibit the expression of genes related to the synthesis of thyroid hormones, thereby significantly improving the clinical symptoms such as exophthalmos and diplopia. The common adverse reactions of Teprotumumab-trbw are muscle spasm, hyperglycemia, hearing loss and so on. Teprotumumab-trbw is effective and durable in the treatment of thyroid-associated ophthalmopathy, and patients with secondary treatment can also benefit from it, which provides a new way and hope for the treatment of thyroid-associated ophthalmopathy.
ABSTRACT
ABSTRACT Purpose: Peribulbar injection of triamcinolone is an alternative treatment for thyroid eye disease; however the safety profile of this therapeutic option remains controversial. The aim of this study was to describe the occurrence of local and systemic adverse effects after peribulbar injection of triamcinolone in patients with thyroid eye disease. Methods: This was a retrospective case series. Medical records of patients with thyroid eye disease treated with peribulbar injections of triamcinolone at a single academic institution between 2007 and 2019 were analyzed. Local and systemic complications were documented. Results: A total of 123 patients were treated. Only 11 patients (8.9%) developed local complications. The most frequent complication was the presence of superficial eyelid ecchymosis (nine patients; 7.3%). Notably, systemic complications (hyperglycemic and suprarenal inhibition after stop treatment) occurred in two patients (1.6%). All complications were transient, and the patients did not have any long-term sequelae. Conclusions: Peribulbar injection of triamcinolone for the treatment of thyroid eye disease is linked to a very low rate of local or systemic complications. Prospective studies are warranted to delve into this topic.
RESUMO Objetivo: A injeção peribulbar de triancinolona é um tratamento alternativo para doenças oculares da tireoide; no entanto, a segurança desse procedimento continua controversa. O objetivo deste artigo é descrever os efeitos adversos locais e sistêmicos de injeções peribulbares de triancinolona em pacientes com doença ocular da tireoide. Métodos: Estudo retrospectivo de uma série de casos. Foram analisados os prontuários médicos dos pacientes com doença ocular da tireoide tratados com injeções de triancinolona peribulbar em uma única instituição acadêmica entre 2007 e 2019. Foram documentadas as complicações locais e sistêmicas. Resultados: Um total de 123 pacientes foram tratados. Apenas 11 (8,9%) pacientes apresentaram complicações locais, sendo a mais frequente a presença de equimoses palpebrais superficiais (7,3%), enquanto 2 (1,6%) pacientes apresentaram complicações sistêmicas (hiperglicemia e inibição da suprarrenal após a interrupção do tratamento). Todas estas complicações foram transitórias e nenhum paciente apresentou sequelas de longo prazo. Conclusões: As injeções peribulbares de triancinolona nas doenças oculares da tireoide têm uma taxa muito baixa de complicações, tanto locais quanto sistêmicas. São necessários estudos prospectivos para aprofundar este tópico.
ABSTRACT
Thyroid-associated ophthalmopathy(TAO)is an autoimmune inflammatory disease involving multiple orbital tissues with a variety of clinical manifestations, which has serious effects on the life quality of patients.Interventions of TAO mainly include medical treatment to stabilize thyroid function, reduce inflammation and regulate immune function, as well as surgical treatment to relieve ocular symptoms. Botulinum toxin type A can paralyze muscles by blocking nerve impulse conduction at the neuromuscular junction, which is of certain therapeutic value for restrictive strabismus due to extraocular muscle involvement and upper eyelid retraction due to involvements of levator palpebrae superioris and Müller's muscle in TAO patients, especially when they have surgical contraindications, lack surgical opportunity, or refuse surgery. This paper reviews the application of botulinum toxin type A in the treatment of TAO, focusing on its pharmacological mechanism, dosage, effectiveness, and possible complications when treating restrictive strabismus and upper eyelid retraction, and discussing potential therapeutic values of botulinum toxin type A for intraocular pressure elevation, glabellar frown lines and dry eye caused by extraocular muscle compression in TAO patients, in order to provide a reference for clinical intervention.
ABSTRACT
AIM: To investigate the effect of orbital decompression on the central macular choroidal thickness(CMCT)in patients with thyroid-associated ophthalmopathy(TAO).METHOD: Prospective clinical studies. A total of 29 TAO patients(42 eyes)treated in our department from January 2021 to January 2022 were analyzed, and they were divided into 20 cases(30 eyes)in the moderate and severe group and 9 cases(12 eyes)in the extremely severe group. Both groups of patients received orbital decompression, and the changes of CMCT, visual acuity, intraocular pressure, exophthalmos, and clinical activity score(CAS)at 3 and 6mo before and after surgery were compared between the two groups.RESULTS: All patients completed follow-up. The CMCT, exophthalmos, intraocular pressure, and CAS of the extremely severe group at 3 and 6mo were 355.13±15.59 and 339.61±13.17μm, 19.33±2.23 and 17.83±1.70mm, 18.86±3.05 and 18.09±1.37mmHg, 3.75±0.87 and 2.42±1.00 points, respectively. The moderate and severe group was 325.00±10.48 and 321.04±11.34μm, 16.07±1.74 and 15.6±1.98mm, 16.65±2.04 and 16.03±2.3mmHg, 1.50±0.51 and 1.43±0.50 points, and there was differences with those before operation(extremely severe group: 396.46±17.61μm, 22.00±2.3mm, 21.85±2.82mmHg, 5.33±1.44 points; moderate and severe group: 335.77±11.60μm, 19.07±1.84mm, 18.89±3.06mmHg, 1.63±0.49 points; all P<0.001). The best corrected visual acuity(LogMAR)before surgery was 0.64±0.22 in the extremely severe group, and 0.43±0.20 and 0.34±0.15 at 3 and 6mo after operation, respectively, which were different from those before surgery(all P<0.001)CONCLUSION: Orbital decompression can effectively reduce CMCT, intraocular pressure and exophthalmos in TAO patients, relieve orbital vein stasis, and effectively improve vision and reduce mobility in patients with extremely severe disease.
ABSTRACT
Interleukin-6(IL-6)is a pleiotropic cytokine produced by monocytes, macrophages, T lymphocytes and other cell types. It is significantly up-regulated in the process of infection and inflammation, and is the core cytokine of the host's defense against environmental stresses(such as injury and infection). Abnormal and persistent IL-6 production is closely associated with the development of various autoimmune and inflammatory diseases. A growing number of studies have shown that IL-6 plays a critical role in ocular inflammation and angiogenesis in the conjunctiva, cornea, uvea and retina. Blockade of IL-6 ameliorates chronic and refractory intraocular inflammation. This article aims to review the role as well as the mechanism of IL-6 in ocular inflammatory diseases, attempting to have a deep and systematic understanding of the role of IL-6 in ocular inflammatory diseases.
ABSTRACT
Thyroid-associated ophthalmopathy(TAO)is an autoimmune disease associated with thyroid dysfunction that can significantly impact quality of life, result in visual impairment and facial disfigurement. Traditional treatments are often unsatisfactory. Studies have shown that teprotumumab, a human monoclonal antibody that can inhibit insulin-like growth factor 1 receptor(IGF-1R), has become an emerging targeted drug for TAO. Although the drug has proven to be effective and relatively safe in the treatment of TAO, adverse reactions are worthy of attention of ophthalmologists with the continuous promotion of clinical application, including hearing impairment, hyperglycemia, diarrhea, muscle spasms, infusion reactions, cognitive decline, thyroid suppression, alopecia, nausea and fatigue. Teprotumumab was generally well tolerated, with most adverse events being mild or moderate in severity. This paper aims to review the adverse reactions and precautions of teprotumumab in the treatment of TAO.

ABSTRACT
Thyroid Eye Disease also known as Thyroid Associated Orbitopathy, Grave’s Disease is typically a self-limiting autoimmune process associated with dysthyroid states usually manifesting in middle age. The clinical presentation may vary from very mild disease to severe irreversible sight threatening complications. Primary risk factors for TED are environmental influences especially smoking, previous pathogen exposures, stress, previous use of radio iodine and complex genetic components. Here we report a case of 25-year-old male who presented to our OPD with complaints of swelling of eyes, photophobia, lacrimation since 3days. Bilateral mild proptosis, severe congestion and conjunctival injection with 20/20 vision in both eyes were noted on examination. Blood investigations showed Eu-clinical Thyroid state whereas MRI Brain and Orbits showed all four Recti muscle belly enlargement. This case emphasizes one of the rare presentations of TED in accordance to Age, Sex and Clinical status of the thyroid.

Purpose: To evaluate changes in the levator palpebrae superioris (LPS) muscle on 3.0 T magnetic resonance imaging (MRI) after triamcinolone acetonide injection for treating upper lid retraction (ULR) with Graves’ ophthalmopathy (GO) and to explore the value of LPS muscle quantitative measurement for clinical treatment. Methods: Patients with GO showing ULR were studied retrospectively and they underwent 3.0 T MRI scans before and after subconjunctival injection o f triamcinolone acetonide. The largest thickness (T) and highest signal intensity (SI) of LPS muscle on the affected eyes were measured in the sequences of coronal T2?weighted, fat?suppressed fast spin echo imaging (T2WI?fs) and T1?weighted, fat?suppressed, contrast?enhanced fast spin echo imaging (T1WI?fs + C), respectively. The SI ratio (SIR) (LPS muscle SI/ ipsilateral temporalis SI) was calculated individually. Depending on the therapeutic effect, patients were divided into effective group and non?effective group. Independent t?test was used to compare SIR and T of LPS muscle in different treatment groups before treatment, and paired sample t?test was used to compare SIR and T of LPS muscle before and after treatment. Then cut?off level for predicting therapeutic effect and the receiver operating characteristic curve (ROC) curve were analyzed. Results: Sixty?two patients (77 eyes) were enrolled. After treatment, the T of LPS muscle showed significant decrease in all sequences in both effective and non?effective treatment groups. However, changes in SIR of LPS muscle in the two groups were different; SIR of LPS muscle on T2WI?fs and T1WI?fs + C decreased after treatment in the effective group (PT2 < 0.001, PT1 + C < 0.001) and SIR of LPS muscle showed no statistically difference in all sequences (all P > 0.05) in the non?effective group. There was a correlation between SIR of LPS muscle before treatment and after treatment with triamcinolone acetonide injection, which was that SIR of LPS muscle in the effective treatment group was lower than that in the non?effective treatment group on T1WI?fs + C (P < 0.001). SIR of LPS muscle on T1WI?fs + C showed 87.5% sensitivity and 66.7% specificity to predict therapeutic effect (area under the ROC curve [AUC] = 0.840). Conclusion: In GO patients with ULR, 3.0 T MRI can be used to evaluate the response of triamcinolone acetonide injection. SIR of LPS may be a predictor of its efficacy
ABSTRACT
ABSTRACT Objective: Graves' ophthalmopathy (GO) is a vision-threatening finding observed in approximately half of Graves' disease patients. The pathophysiology of GO is unclear, and one of the suspected factors is oxidative stress. In our study, we compared the relationship between proptosis and SH-SS in patients diagnosed with GO. Materials and methods: In this prospective study, 40 recently diagnosed Graves' disease patients with proptosis, 40 recently diagnosed Graves' disease patients without GO and 30 healthy individuals with similar demographic characteristics were included. Serum thiol-disulfide (SH-SS) measurements were performed. Eye examinations were performed by a single ophthalmologist to check for the presence of GO, and proptosis values were recorded with a Hertel exophthalmometer. Results: Total SH values were lower in the group with proptosis than in the other groups (p < 0.05). Total and native SH values were lower in patients without proptosis than in the control group (p < 0.05). Total SH, native SH and SS levels were independently associated with proptosis (p < 0.05). According to this analysis, it was found that increasing SS and decreasing total and native SH levels increased the probability of proptosis by 24.4%, 32.7% and 32.4%, respectively. Conclusion: A decrease in SH, which is a natural antioxidant that protects the body against oxidative stress, and an increase in SS are important signs of oxidative damage. Proptosis and SH-SS are closely related in GO. This may help us detect GO and proptosis in Graves' patients. It can also assist in developing new options for preventing and treating GO.
ABSTRACT
Introduction There are some inflammatory, infectious, and neoplastic diseases affecting the extrinsic orbital musculature (EOM) that present with pain, decreased visual acuity, and proptosis. Imaging is fundamental to the differential diagnoses of these diseases with similar clinical presentations. The present case series report has as main objective to illustrate and discuss the main pathologies that affect the orbit. Material and Methods The present series of cases discusses the main pathologies that can affect the extraocular musculature that can be characterized by computed tomography (CT) or magnetic resonance imaging (MRI) using cases from our institution. Results and Discussion The present study compiled several cases of ophthalmopathy from our institution to illustrate and address some of these pathologies, such as orbital lymphoma, Grave disease, metastases, periorbital cellulitis, and idiopathic orbital inflammatory syndrome. The diseases are discussed according to the presentation of clinical cases with emphasis on the main imaging findings of each pathology. Conclusion Computed tomography and MRI can help in the diagnosis and follow-up of the diseases that affect the EOM. We must be conversant with the main characteristics of the pathologies presented in the present case series report, since such findings together with clinical data can confirm the diagnosis of these diseases or at least help to narrow the differential diagnoses.

Objective:To investigate the value of magnetization transfer imaging (MTI) and fat suppression T 2WI (FS-T 2WI) in predicting the clinical activity of Graves ophthalmopathy (GO). Methods:From October 2020 to July 2021, 64 GO patients were prospectively enrolled in the First Affiliated Hospital of Nanjing Medical University. According to the clinical activity score (CAS), the patients were divided into active group (CAS≥3, 39 patients and 78 eyes) and inactive group (CAS<3, 25 patients and 50 eyes). The coronal MTI and FS-T 2WI were scanned for pre-treatment assessment. Magnetization transfer ratio (MTR) of extraocular muscles, and signal intensity ratio (SIR) between extraocular muscles and temporalis were measured, respectively. The independent-sample t-test was used to compare the MTR and SIR between two groups. The correlations between MRI parameters and CAS were analyzed using Spearman correlation analysis. The receiver operating characteristic (ROC) curve was performed to evaluate the value of each and combined parameters for predicting the clinical activity of GO. The DeLong test was used to compare the area under the curve (AUC). Results:The MTR of active group and inactive group were 0.45±0.04 and 0.51±0.04, respectively, the difference was statistically significant ( t=7.62, P<0.001). The SIR were 3.4±0.6 and 2.6±0.5, respectively, and the difference was also statistically significant ( t=-8.20, P<0.001). MTR was negatively correlated with CAS ( r=-0.46, P<0.001), while SIR was positively correlated with CAS ( r=0.63, P<0.001). The AUC of MTR, SIR and the combination of MTR and SIR for predicting the clinical activity of GO were 0.840, 0.845 and 0.905, respectively. The combination of MTR and SIR showed higher performance than MTR or SIR alone, and the differences were statistically significant ( Z=2.61, P=0.009; Z=2.15, P=0.032). Conclusions:The quantitative parameters of MTI and FS-T 2WI, namely MTR and SIR, can be used to evaluate the clinical activity of GO. Integrating MTI and FS-T 2WI can improve the diagnostic efficiency.
ABSTRACT
Thyroid-associated ophthalmopathy (TAO) is a common orbital disease in the adults, which leads to a series of ocular symptoms and signs, seriously affecting the visual function and life quality of patients.Grasping the disease progression accurately and evaluating the severity and activity of TAO objectively play a crucial role in improving the management and prognosis of TAO patients.Grading and staging methods of TAO have been constantly improved.In the descriptive evaluation of subjective symptoms and signs of TAO, four international grading and staging systems with similarities and different focuses, namely, NOSPECS, CAS, VISA and EUGOGO, have been proposed successively.In recent years, with the rapid development of science and technology, objective evaluation methods such as imaging technology and laboratory examination have played an important role in the grading and staging of TAO.Among them, the application of orbital CT and MRI has made a great breakthrough in quantitative analysis of the disease.Continuous summary of grading and staging methods of TAO can contribute to the guidance for improving diagnosis, treatment and prognosis of TAO.
ABSTRACT
Objective:To identify the proteins differentially expressed in extraocular muscles between restrictive strabismus patients with thyroid-associated ophthalmopathy (TAO) and concomitant esotropia patients by proteomic analysis using tandem mass tag (TMT).Methods:Extraocular muscles samples from 5 restrictive strabismus patients with TAO and 5 concomitant esotropia patients were collected at Peking University People's Hospital from August 2019 to December 2020.All the patients received strabismus surgery.Differentially expressed proteins (DEPs) in extraocular muscles samples were identified by quantitative proteomic analysis and bioinformatic analysis based on TMT.Fold change≥1.2 or≤0.83 and P value<0.05 was regarded as the threshold to screen DEPs.GO annotation, KEGG pathways enrichment analysis and protein-protein interaction (PPI) network of DEPs were conducted through UniProtGOA and STRING.This study protocol was approved by the Ethics Committee of Peking University People's Hospital (No.2021PHB058-001). Results:A total of 53 DEPs were identified, 34 of which were up-regulated and 19 were down-regulated.The biological processes DEPs mainly participated included response to stimulation, multicellular organismal process, metabolism, developmental process, intracellular signal transduction, and positive regulation of biological process.DEPs were involved in pathways including focal adhesion, tight junction, regulation of action cytoskeleton, and apoptosis.Six key proteins identified using PPI network were myosin heavy chain 2, myosin heavy chain 7, myosin regulatory light chain, α-actinin-2, fibrinogen alpha chain and fibrinogen beta chain.Conclusions:There are DEPs in extraocular muscles between restrictive strabismus patients with TAO and concomitant esotropia patients.Myosin, actinin and filamin may be involved in the pathogenesis of TAO through regulation of actin cytoskeleton and focal adhesion.
ABSTRACT
Graves' ophthalmopathy is the most common clinical orbital disease, and T helper (Th) cells play an important role in the development of Graves' ophthalmopathy. Th17 cells are a major subpopulation of Th cells and abnormally highly expressed in patients with Graves' ophthalmopathy. Th17 cells and the related cytokines interleukin (IL)-17A, IL-21 and IL-23 are involved in regulating the inflammatory response, fibrosis and adipogenesis. Th17 cells are unstable and exhibit a degree of plasticity, and they can differentiate into IL-17A and interferon (IFN)-γ dual-producing Th17.1 cells, which exacerbate the pathogenicity of Th17 cells. In addition, Th17 cells and the relevant factors are strongly associated with disease activity and severity in Graves' ophthalmopathy.
