Abstract
Graves'-associated upper eyelid retraction (GAUER) is the commonest manifestation of orbitopathy in adults. Surgical management typically follows a 3-step staged approach commencing with orbital decompression. The rationale behind this is that certain surgical interventions can influence the parameters and outcomes of subsequent procedures. We performed a systematic review and meta-analysis evaluating the effects of orbital decompression on GAUER in adult patients with Graves' orbitopathy. All original English, non-pediatric studies meeting the study inclusion criteria from the last 20 years were included. The characteristics of margin reflex distance 1 (MRD-1) pre- and post-orbital decompression of 688 orbits were collected, and a meta-analysis of 472 orbits was performed. The average reduction in MRD-1 across 688 orbits was found to be 0.40 mm. Meta-analysis of 6 applicable articles demonstrated that orbital decompression decreases MRD-1 by an average of 0.35 mm (n = 472, p = .007, 95% CI = [0.08, 0.63]). This study demonstrates that although statistically significant, orbital decompression does not appear to have a clinically significant effect on GAUER. This has implications for clinical practice, namely the likely requirement of eyelid surgery following or in combination with orbital decompression, and the importance of counselling patients on this preoperatively.

Abstract
PURPOSE The superior orbital fissure contains cranial nerves III, IV, VI, and V1 with their three branches: frontal, lacrimal, and nasociliary. Superior orbital fissure syndrome (SOFS) is rare and can occur as a result of compression of these nerves due to trauma, bleeding, or inflammation in the retrobulbar space, but no cases of SOFS after deep lateral orbital wall decompression (DLOWD) have been reported. The aim of this paper is to describe this pathology, its possible causes, management, and outcome. METHODS Retrospective study of 575 DLOWD in patients with disfiguring exophthalmos due to Graves' ophthalmopathy performed in our hospital between 2010 and 2023. Three cases of postoperative SOFS were identified based on clinical presentation, history, physical examination, and radiological study. All patients were observed for a minimum of 12 months. RESULTS SOFS was diagnosed with the presence of ophthalmoplegia, ptosis, fixed and dilated pupils, hypo/anesthesia of the upper eyelid and forehead, loss of corneal reflex, and no loss of vision after DLOWD. Fractures, edema, and hemorrhages were excluded. They were treated with high-dose intravenous steroids and the patients recovered completely. CONCLUSIONS DLOWD challenges orbital surgeons because it requires removing bones near the globe or neurovascular structures. SOFS may occur due to the proximity and increased pressure on these structures.

Abstract
BACKGROUND Discriminating the stage of Graves' ophthalmopathy (GO) is crucial for clinical decision. Application of conventional T2-weighted imaging in the staging is still limited. PURPOSE To evaluate the performance of T2 mapping based on two different regions of interest (ROIs) for staging GO. MATERIAL AND METHODS In total, 56 GO patients were retrospectively enrolled and divided into two groups according to the clinical activity score (CAS). T2 relaxation time (T2RT) of extraocular muscle (EOM) on T2 mapping based on two different ROIs (T2RTROI-1: ROIs were drawn separately in the four EOMs; T2RTROI-2: ROI was drawn in the most inflamed EOM) was measured and compared between active and inactive groups. RESULTS Both T2RTROI-1 and T2RTROI-2 values in the active GO were significantly higher than those of inactive GO (P <0.001). T2RTROI-1 and T2RTROI-2 values were positively correlated with CAS (rs=0.73, 0.69; P <0.001). When the T2RTROI-1 value of 83.3 ms and T2RTROI-2 value of 106.3 ms were used as cutoff values for staging GO, respectively, the best results were obtained with areas under the curve (AUCs) of 0.822 and 0.827. There was no significant difference for AUCs between T2RTROI-1 and T2RTROI-2 (P = 0.751). Excellent and good inter-observer agreements were achieved in quantitative measurements for T2RTROI-1 and T2RTROI-2 values, respectively, with intraclass correlation coefficients of 0.954 and 0.882. CONCLUSION The T2RT values derived from two different ROIs were useful for assessment of disease activity. Taking reproducibility and diagnostic performance into consideration, T2RTROI-1 would be an ideal image biomarker for staging GO compared to T2RTROI-2.

Abstract
PURPOSE Thyroid eye disease (TED) is the foremost extrathyroidal manifestation of Graves' disease (GD). Currently, available treatments do not entirely prevent the long-term consequences of TED and have distinct disadvantages. Therefore, this systematic review explored available evidence regarding the efficacy of statins in preventing and treating TED. METHODS Relevant studies investigating statin usage in patients with GD or TED were identified by searching Medline (Pubmed and Ovid), Scopus, Web of Science, ProQuest, and Cochrane Library databases (from the database inception to September 2023). The review was done according to the PRISMA statement. Web searching was done independently by two investigators. Two researchers independently extracted the data, and any disagreement was adjudicated by consensus. Based on the study design, the studies' quality appraisal was done using the Newcastle-Ottawa Scale (NOS) and Version 2 of the Cochrane risk-of-bias tool (RoB2). RESULTS The literature search identified 145 publications, of which four met the inclusion criteria (Three retrospective cohort studies and one randomized clinical trial) and were reviewed in full text. The two retrospective cohort studies demonstrated the beneficial effects of statins on TED in newly diagnosed GD Stein et al. showed that statins, regardless of the type, prevent or delay TED (HR: 0.74 (0.65-0.84)), especially in men or treatment duration of more than one year. Nilsson et al. fascinatingly revealed that at least 60 days of statin usage in the preceding year could decrease the risk of TED development by around 40%. One RCT showed a higher treatment response for active moderate-to-severe TED in patients with hypercholesterolemia who took atorvastatin 20 mg in addition to ivGC for 24 weeks without any increase in serious side effects. The retrospective study revealed that the need for reconstructive surgery was reduced in patients with severe TED who received statin therapy. CONCLUSION Statin therapy could be a potential adjunctive modality for preventing and treating TED. TRIAL REGISTRATION PROSPERO registration number: CRD42022315522.

Abstract
PURPOSE To evaluate the Schlemm's canal (SC) parameters obtained by swept-source optical coherence tomography (OCT) different in Graves' ophthalmopathy (GO) eyes compared to healthy eyes. METHODS This cross-sectional observational study evaluated 64 eyes of 32 GO cases and 56 eyes of 28 healthy controls. The study was conducted between October 2020 and June 2021. SC images were obtained from the temporal limbus of individuals using swept-source OCT. SC length (SCL) and SC area (SCA) were measured. The relationship between SC parameters in the patient group and intraocular pressure (IOP), retinal nerve fiber layer (RNFL) thickness, Graves' disease (GD) duration, and clinical activity score (CAS) was evaluated. RESULTS In the GO group, 64 eyes of 32 patients were evaluated, and in the age and gender-matched healthy control group, 56 eyes of 28 individuals were assessed. SC images from 4 eyes of 4 patients in the patient group and 1 eye of 1 patient in the control group were not clear, preventing SCL and SCA measurements for these eyes. SCL and SCA measurements were found to be lower, and IOP and Hertel values were higher in the GO group compared to the healthy controls. However, no significant correlation was observed between SCL and SCA with IOP, RNFL thickness, GD duration, GO duration, or CAS in the GO group. In the GO group, the mean value of SCA was found to be higher in eyes with glaucoma or OHT compared to those without. CONCLUSION These findings indicate that SC in GO-affected eyes is shorter and has a smaller area than in healthy individuals. Additionally, higher IOP and Hertel values were observed in the GO group compared to healthy controls. This study suggests that assessing SC using anterior segment OCT could provide valuable insights into the regulation of IOP and the development of glaucoma in GO-affected eyes.

Abstract
PURPOSE Strabismus reoperation in Graves' ophthalmopathy (GO) is complicated and challenging. The purpose of this study was to evaluate the various surgical strategies of strabismus reoperation and their outcomes in patients with GO. METHODS A retrospective study was conducted on strabismus reoperations performed at the Zhongshan Ophthalmic Center of Sun Yat-sen University, Guangzhou, China from 2008 to 2018. Data collected included sex, age at surgery, duration of deviation, ocular alignment, ocular motility, various surgical procedures performed and surgical outcomes. Surgical methods included rectus recession for newly developed strabismus, rectus resection for undercorrection and anterior advancement of a previously recessed rectus for overcorrection. Surgical success was defined as an absence of diplopia, a horizontal deviation of ≤ 10 prism diopters (PD) and a vertical deviation of ≤ 5 PD at distance in primary and reading positions. RESULTS Of the 153 GO patients receiving strabismus surgery, 27 cases (20 males, 7 females) underwent reoperation for strabismus, with a reoperation rate of 17.6%. Success rates of reoperation in patients with a previous undercorrection and overcorrection were 45% and 71.4%, respectively. Success rates of rectus recession, rectus resection and anterior advancement were 47.1%, 66.7% and 50%, respectively. Two patients underwent the third surgery. The overall success rate was 51.9%. CONCLUSIONS Rectus recession is an effective method for GO patients with newly-developed strabismus. Rectus resection may benefit some patients with undercorrection who underwent a maximal degree of rectus recession. Anterior advancement of a previously recessed rectus is effective for cases with overcorrection.

Abstract
Graves' disease (GD) and Graves' ophthalmopathy (GO) are complex autoimmune diseases. This study delved into the impact of cigarette smoke extract (CSE), simvastatin, and/or diclofenac on peripheral blood mononuclear cells (PBMCs). Specifically, we explored alterations in IL-1B, IL-6, PTGS2 expression, B- and T-lymphocyte proliferation, and Immunoglobulin G (IgG) production. We also assessed IGF1's influence on B- and T-lymphocyte proliferation. PBMCs from Graves' patients were exposed to CSE with/without simvastatin and/or diclofenac. Gene and protein expression was compared with untreated PBMCs. B- and T-lymphocyte proliferation was assessed following IGF1 treatment. PBMCs exposed to CSE exhibited increased expression of IL-1B (6-fold), IL-6 (10-fold), and PTGS2 (5.6-fold), and protein levels of IL-1B (4-fold), IL-6 (16-fold) and PGE2 (3.7-fold) compared with untreated PBMCs. Simvastatin and/or diclofenac downregulated the expression of PTGS2 (0.5-fold), IL-6 (0.4-fold), and IL-1B (0.6-fold), and the protein levels of IL-1B (0.6-fold), IL-6 (0.6-fold), and PGE2 (0.6-fold) compared with untreated PBMCs. CSE exposure in PBMCs increased the proliferation of B and T lymphocytes by 1.3-fold and 1.4-fold, respectively, compared with untreated. CSE exposure increased IgG (1.5-fold) in supernatant from PBMCs isolated from Graves' patients. IGF1 treatment increased the proliferation of B and T lymphocytes by 1.6-fold. Simvastatin downregulated the proliferation of B and T lymphocytes by 0.7-fold. Our study shows that CSE significantly upregulated the expression and release of the inflammatory markers PTGS2, IL-6 and IL-1B,the IgG levels, and the proliferation of B and T lymphocytes. Additionally, IGF1 increased the proliferation of B and T lymphocytes. Finally, these effects were decreased by diclofenac and/or simvastatin treatment.

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
INTRODUCTION Graves' ophthalmopathy (GO) is an autoimmune inflammatory disorder observed in a substantial proportion of patients with Graves' disease (GD), with debilitating symptoms of disfiguring, periorbital pain, dry eyes, diplopia, and even visual disturbances. Previous studies involving Western populations have noted discrepancies in risk factors for GO. Therefore, this study aimed to determine the risk factors for GO development and the protective effect of statins in newly diagnosed patients with GD in Taiwan. METHODS This retrospective case-control study was based on a tertiary center cohort involving patients with GD diagnosed between 2010 and 2019 at the National Taiwan University Hospital (n = 11,035). Patients who were diagnosed or treated elsewhere, had been followed up for less than 6 months or were with a diagnosis of orbital tumor were excluded. Overall, 3578 patients with GD met the inclusion criteria. Univariate and multivariate logistic regression analyses were used to ascertain the odds ratio (OR) of developing GO, with adjustment for sociodemographic factors, interventions for managing GD and thyroid hormone levels, to determine protective and risk factors for GO. RESULTS In our multivariate model, the use of statins reduced the risk of GO development (OR 0.2; 95% confidence interval [CI] 0.08-0.50; p < 0.001). Thyroid dysfunction including hyperthyroidism (OR 4.2; 95% CI 2.97-5.88; p < 0.001) and hypothyroidism (OR 4.7; 95% CI 3.02-7.19; p < 0.001) was associated with an increased risk of developing GO. Smoking status and lipid profile were not risk factors in our cohort. CONCLUSION In newly diagnosed patients with GD, the use of statins decreased the risk of developing GO by 80%, whereas serum lipid levels were not considered risk factors. Further nationwide population-based studies may help clarify the differences in risk factors between various ethnic groups. TRAIL REGISTRATION This trial was approved by the Research Ethics Committee of National Taiwan University Hospital (202202066RINC), retrospectively registered from January 1, 2010 to December 31, 2019.

Abstract
PURPOSE Persistent diplopia after rectus muscle myectomy is not uncommon but challenging in patients with Graves' ophthalmopathy. We investigated the role of lateral rectus muscle resection for patients after medial rectus muscle myectomy in Graves' ophthalmopathy. METHODS We retrospectively reviewed and collected data from patients with persistent diplopia after medial rectus muscle myectomy for Graves' ophthalmopathy who underwent unilateral or bilateral lateral rectus muscle resection. The eyeball deviations in the primary and reading positions before and after the operation were measured. A successful surgical outcome was defined as having less than five prism diopters (PD) in the primary gaze and functional binocular vision in the central 30° field postoperatively. RESULTS A total of fifteen patients were included (mean post-myectomy deviation: 35.9 PD, range: 14 to -75 PD). The lateral rectus muscle resection after medial rectus muscle myectomy achieved an 80.0% success rate, with one patient over-corrected and two patients under-corrected. CONCLUSIONS The lateral rectus muscle resection is an effective and predictable procedure for managing residual esotropia in Graves' ophthalmopathy patients who have previously undergone medial rectus muscle myectomy.

Abstract
Background: Graves' ophthalmopathy (GO) is characterized by upper eyelid retraction (UER), the most prevalent clinical sign. We aimed to assess the clinical efficacy of a multimodal combination of steroids, 5-fluorouracil (5-FU), and botulinum neurotoxin A (BoNT-A) injections in managing UER with GO and analyze the clinical factors in relation to the injection response. Methods: A total of 37 eyes from 23 patients were enrolled for UER with GO. At the endocrinology clinic, the patients were referred to the ophthalmology clinic after taking antithyroid medication for an average of 5.76 months (13 patients), while 10 patients were initially diagnosed with GO and referred to the endocrinology clinic for management of the thyroid hormone function. They performed an orbital computed tomography (CT) scan and measured the cross-sectional area of the orbit, orbital fat, and each extra ocular muscle (EOM) except for the inferior oblique muscle 4 mm behind the eyeball. Each of the EOMs and orbital fat were calculated as a ratio to the total orbit area. A total of 0.1 cc of triamcinolone (40 mg/mL), dexamethasone (5 mg/mL), 5-FU, and BoNT-A (2.5 units) was injected transconjunctivally. Medical records were examined and photographs were utilized to assess MRD1, inferior palpebral fissure (IPF), and lid lag during down gaze before and after the injection. The patients were divided into two groups: responders (more than 1 mm decrease in MRD1 after injection) and non-responders. During the follow-up period (11.0 ± 11.6 months), any potential adverse effects were monitored. Results: CAS decreased from 3.0 ± 0.8 to 1.4 ± 0.5 after the injection, and MRD1 decreased from 5.0 ± 0.9 mm to 4.5 ± 1.3 mm. Sixty percent of the patients were responders. Before and after the injection, the difference between IPF and MRD1 in responders was 0.60 ± 1.10 mm and 0.90 ± 0.90 mm, respectively, whereas, in non-responders, it was -0.57 ± 0.88 mm and -0.15 ± 0.75 mm, respectively. In the responders, pre-injection IPF and FT4 were significantly higher (p < 0.05). Responders had a larger EOM cross-sectional area (153.5 ± 18.0 mm2), including a larger lateral rectus muscle cross-sectional area (37.6 ± 9.7 mm2) than non-responders (132.0 ± 27.9 mm2; 29.1 ± 8.1 mm2). In responders, the treatment effect on IPF and MRD1 remained consistent at 1.2 ± 3.4 mm and 1.2 ± 1.6 mm, respectively, during the latest follow-up assessment. Conclusions: The combination injection of corticosteroids, 5-FU, and BoNT-A would be effective, especially, in patients with hyperthyroidism and an elongated IPF. Additionally, an increase in EOM cross-sectional area on CT, up to 150 mm2, may serve as an additional positive indicator for the use of multimodal injections in UER with GO.

Abstract
Objectives Forkhead box P3 (FOXP3) gene polymorphisms have been evaluated in many autoimmune diseases, including Graves' disease (GD), in different populations. However, those polymorphisms have not been analyzed in GD or Graves' ophthalmopathy (GO) in the Turkish population. In this study, we aimed to evaluate the frequency of FOXP3 polymorphisms in GD with or without ophthalmopathy in a Turkish population. Materials and Methods The study included 100 patients with GO, 74 patients with GD without ophthalmopathy, and 100 age- and sex-matched healthy controls. In all study participants, rs3761547 (-3499 A/G), rs3761548 (-3279 C/A), and rs3761549 (-2383 C/T) single nucleotide polymorphisms (SNPs) were detected using the polymerase chain reaction-restriction fragment length polymorphism method. The chi-square test was used to evaluate genotype and allele frequencies. Odds ratios and 95% confidence intervals were calculated for genotype and allele risks. Results In the patient group (including GD with or without ophthalmopathy), the rs3761548 AC and AA genotype and rs3761549 CT genotype were significantly more frequent than in the control group (all p<0.05). No genotypic and allelic differences were observed for rs3761547 between the patient and control groups (all p>0.05). There was no statistically significant difference between the GO and GD without ophthalmopathy groups concerning the allele and genotype frequencies of all three FOXP3 SNPs (all p>0.05). Conclusion The AC and AA genotypes of rs3761548 (-3279) and CT genotype of rs3761549 (-2383 C/T) were shown to be possible risk factors for GD development in the Turkish population. However, none of the three SNPs was shown to be associated with the development of GO in patients with GD.

Abstract
PURPOSE To determine the microvascular and structural changes in the peripapillary and macular areas observed in patients with active thyroid orbitopathy(TO) before and after steroid treatment and compare with inactive TO and the control group by optical coherence tomography angiography (OCTA). MATERIAL AND METHOD This cross-sectional study included 34 eyes of 17 active TO patients, 108 eyes of 54 inactive TO patients, and 60 eyes of 30 healthy controls. Central macular thickness (CMT), ganglion cell layer-inner plexiform layer (GCL-IPL) thickness, central choroidal thickness (CCT), retinal nerve fiber layer (RNFL) thickness, choroidal thickness in the peripapillary region, superficial capillary plexus (SCP), deep capillary plexus (DCP) and choriocapillaris vessel densities were determined by OCTA in before and after 12-week steroid treatment of active TO cases, inactive TO and control groups. RESULTS Between the three groups in macula OCTA, a statistically significant difference was observed in the inferior and nasal quadrants in SCP (all p = 0.01) and only in the temporal quadrant choriocapillaris (p = 0.005). In peripapillary OCTA, a statistically significant difference was found only in the central choriocapillaris (p = 0.03). In the comparison of the active group before and after treatment, there was a statistically significant decrease in CMT and CCT; a statistically significant increase was observed in GCL-IPL (all p < 0.01). There was a statistically significant decrease in SCP and DCP only in the central (all p < 0.01). There was a statistically significant increase was found in the lower quadrant macular SCP vessel density and mean macular DCP in post-treatment measurements (p = 0.01 and p = 0.03, respectively). Peripapillary SCP and DCP vessel density was increased after treatment (p < 0.01). CONCLUSION Active TO group had lower vessel density than inactive group and after treatment, vessel density was increased. Non-invasive quantitative analysis of retinal and optic disc perfusion using OCTA could be useful in early treatment before complications occur and monitoring patients with TO.

EZH2 as a major histone methyltransferase in PDGF-BB-activated orbital fibroblast in the pathogenesis of Graves' ophthalmopathy. Sci Rep 2024; 14:7947.

Abstract
Graves' ophthalmopathy (GO) is an extra-thyroidal complication of Graves' disease which can lead to vision loss in severe cases. Currently, treatments of GO are not sufficiently effective, so novel therapeutic strategies are needed. As platelet-derived growth factor (PDGF)-BB induces several effector mechanisms in GO orbital fibroblasts including cytokine production and myofibroblast activation, this study aims to investigate the roles of histone lysine methyltransferases (HKMTs) in PDGF-BB-activated GO orbital fibroblasts by screening with HKMTs inhibitors library. From the total of twelve selective HKMT inhibitors in the library, EZH2, G9a and DOT1L inhibitors, DZNeP, BIX01294 and Pinometostat, respectively, prevented PDGF-BB-induced proliferation and hyaluronan production by GO orbital fibroblasts. However, only EZH2 inhibitor, DZNeP, significantly blocked pro-inflammatory cytokine production. For the HKMTs expression in GO orbital fibroblasts, PDGF-BB significantly and time-dependently induced EZH2, G9a and DOT1L mRNA expression. To confirm the role of EZH2 in PDGF-BB-induced orbital fibroblast activation, EZH2 silencing experiments revealed suppression of PDGF-BB-induced collagen type I and α-SMA expression along with decreasing histone H3 lysine 27 trimethylation (H3K27me3) level. In a more clinically relevant model than orbital fibroblast culture experiments, DZNeP treated GO orbital tissues significantly reduced pro-inflammatory cytokine production while slightly reduced ACTA2 mRNA expression. Our data is the first to demonstrate that among all HKMTs EZH2 dominantly involved in the expression of myofibroblast markers in PDGF-BB-activated orbital fibroblast from GO presumably via H3K27me3. Thus, EZH2 may represent a novel therapeutics target for GO.

Abstract
PURPOSE To assess changes in monocyte-to-high-density lipoprotein (HDL) ratio (MHR), neutrophil-to-lymphocyte ratio (NLR), and systemic immune-inflammation index (SII) with Graves' ophthalmopathy (GO) and their possible relation with GO disease activity and severity. METHODS A total of 20 patients with GO and 24 healthy controls were involved in the study. The thyroid status, MHR (monocyte count/HDL cholesterol level), NLR (neutrophil count/lymphocyte count) and SII [(neutrophil count × platelet count)/lymphocyte count] were compared between the groups. The relation of systemic inflammation parameters with disease activity and severity was evaluated. RESULTS The mean Clinical Activity Score (CAS) was 0.75 ± 0.78 in the GO group. None of the patients were active. The severity was mild for 14 (70.0%) patients and moderate-to-severe for 6 (30.0%) patients. MHR (17.28 ± 5.56 vs. 13.28 ± 5.08), NLR (2.51 ± 1.09 vs. 1.69 ± 0.53) and SII [600.42 (391.79-837.16) vs. 413.69 (344.26-603.82)] values were significantly increased in GO patients than in the controls (p = 0.017, p = 0.005 and p = 0.036, respectively). CAS was significantly correlated with MHR (r = 0.815, p < 0.001), NLR (r = 0.768, p = 0.017) and SII (r = 0.837, p < 0.001). The severity of GO was associated with increased MHR, NLR and SII (p = 0.019, p = 0.036 and p = 0.008, respectively). ROC analysis demonstrated that MHR, NLR and SII have a good ability to differentiate GO patients from healthy individuals. CONCLUSION GO patients have higher MHR and SII levels than healthy controls. Higher MHR, NLR and SII values were associated with increasing disease severity and activity, supporting the efficacy of these non-invasive, low-cost markers in determining the course of GO. Future prospective controlled trials are needed to elucidate the relation between inflammatory markers and GO.

Abstract
PURPOSE This review analyzed the top 100 most-cited thyroid eye disease (TED) papers. METHODS In November 2022, Scopus was searched for the most highly cited TED works since inception. For each paper, journal of origin and impact factor, corresponding author country and specialty affiliation, citation count, publication year, database-affirmed study funding, and open-access status were extracted. RESULTS A total of 76 primary and 24 secondary articles were published between 1969 and 2021 across 29 journals, with a median (range) of 186.5 (133-930) citations. The most cited journal was Journal of Clinical Endocrinology and Metabolism (25 articles; 5126 citations). The most cited article was 'Graves' ophthalmopathy' (Bahn 2010; New England Journal of Medicine; 930 citations). Articles hailed from 10 countries, with most from the United States (38 articles; 9194 citations). Endocrinology (n = 59) and ophthalmology (n = 26) were the most common corresponding authors. Nineteen first authors contributed multiple articles. Only journal impact factor was significantly associated with citation count (p = .0002; ρ = 0.45). CONCLUSION A variety of medical disciplines, Western countries, and study personnel contributed to highly cited thyroid eye disease research. Thus, this research area is not exceedingly informed by any singular perspective. Further, it can be interpreted with increased confidence for their generalizability of results to patients globally.

Abstract
OBJECTIVE There is currently no recommendation on the optimal surgical management for dysthyroid optic neuropathy (DON). The aim of this study is to systematically review the surgical management of DON and its outcome on visual acuity (VA). DATA SOURCES MEDLINE, Cochrane Library, and clinicaltrials.gov REVIEW METHODS: A systematic review of studies about the surgical management of DON was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Articles were included if preoperative and postoperative VA in logMAR (Logarithm of the Minimum Angle of Resolution) were available. RESULTS Fifteen articles were included in the study accounting for 669 orbits. The mean VA improvement was of 0.44 logMAR overall, 0.41 logMAR for 1-wall, 0.41 logMAR for 2-wall, and 0.55 logMAR for 3-wall decompressions. The mean reduction in exophthalmos was 4.9 mm overall, 4.3 mm for 1-wall, 4.54 mm for 2-wall, and 6.02 for 3-wall decompressions. The mean new onset diplopia (NOD) rate was 19.84% overall, 19,12% for 1-wall, 20.75% for 2-wall, and 19.83% for 3-wall decompressions. CONCLUSION The results are limited due to the high number of biases in the included studies. It seems that 3-wall decompression offers the best VA improvement and proptosis reduction although also the highest NOD and complications rate. Two-wall balanced decompression or 1-wall inferomedial decompression seems to be effective with less morbidity.

Abstract
Graves' ophthalmopathy (GO) affects up to 50% of patients with Graves' disease (GD) ranging from mild ocular irritation to vision loss. The initial diagnosis is based on clinical findings and laboratory tests. Orbital imaging, such as magnetic resonance imaging (MRI) and computed tomography (CT), is an important tool to assess orbital changes, being also useful for understanding disease progression and surgical planning. In this narrative review, we included 92 studies published from 1979 to 2020 that used either MRI and/or CT to diagnose and investigate GO, proposing new methods and techniques. Most of the methods used still need to be corroborated and validated, and, despite the different methods and approaches for thyroid eye disease (TED) evaluation, there is still a lack of standardization of measurements and outcome reports; therefore, additional studies should be performed to include these methods in clinical practice, facilitating the diagnosis and approach for the treatment of TED.

Abstract
This study aimed to evaluate the diagnostic value of uptake ratios in the extraocular muscles (EOMs), lacrimal glands, and optic nerves to detect the inflammation activity of Graves' ophthalmopathy (GO) using quantitative analysis of 99m technetium (99mTc)-labeled diethylene triamine pentaacetic acid (DTPA) orbital single-photon emission computed tomography/computed tomography (SPECT/CT) images. The patients were categorized into an active stage (clinical activity score ≥ 3/7, n=23) or an inactive stage (clinical activity score < 3/7, n=38), based on their clinical activity score. The uptake ratio was manually determined by placing a region of interest within the area of highest uptake, as agreed upon by consensus, in the EOMs, lacrimal gland, and optic nerve on SPECT images corrected for CT attenuation. Patients with active GO exhibited significantly higher uptake ratios in the EOMs, lacrimal glands, and optic nerves compared to patients with inactive GO (all P < 0.01). These parameters have been proven effective in differentiating between active and inactive disease.

Abstract
OBJECTIVES To evaluate the diagnostic performance of the extraocular muscle volume index at the orbital apex (AMI) and the signal intensity ratio (SIR) of the optic nerve in dysthyroid optic neuropathy (DON). METHODS Clinical data and magnetic resonance imaging were collected retrospectively from 63 Graves' ophthalmopathy patients, including 24 patients with DON and 39 without DON. The volume of these structures was obtained by reconstructing their orbital fat and extraocular muscles. The SIR of the optic nerve and axial length of eyeball were also measured. The posterior 3/5 of the retrobulbar space volume was used as the orbital apex to compare parameters in patients with or without DON. Area under the receiver operating characteristic curve (AUC) analysis was used to select the morphological and inflammatory parameters with the highest diagnostic value. A logistic regression was performed to identify the risk factors of DON. RESULTS One hundred twenty-six orbits (35 with DON and 91 without DON) were analyzed. Most of the parameters in DON patients were significantly higher than in non-DON patients. However, the SIR 3 mm behind the eyeball of the optic nerve and AMI had the highest diagnostic value in these parameters and are independent risk factors of DON by stepwise multivariate logistic regression analysis. Combining AMI and SIR had a higher diagnostic value than a single index. CONCLUSIONS Combining AMI with SIR 3 mm behind the eyeball's orbital nerve can be a potential parameter for diagnosing DON. CLINICAL RELEVANCE STATEMENT The present study provided a quantitative index based on morphological and signal changes to assess the DON, allowing clinicians and radiologists to monitor DON patients timely. KEY POINTS The extraocular muscle volume index at the orbital apex (AMI) has excellent diagnostic performance for dysthyroid optic neuropathy. A signal intensity ratio (SIR) of 3 mm behind the eyeball has a higher AUC compared to other slices. Combining AMI and SIR has a higher diagnostic value than a single index.

Abstract
Graves' ophthalmopathy (GO) is a hyperthyroidism-related and immune-mediated disease that poses a significant threat to human health. The pathogenesis of GO primarily involves T cells, B cells, and fibroblasts, suggesting a pivotal role for the thyrotropin-antibody-immunocyte-fibroblast axis. Traditional treatment approaches for Graves' disease (GD) or GO encompass antithyroid drugs (ATDs), radioactive iodine, and beta-blockers. However, despite decades of treatment, there has been limited improvement in the global incidence of GO. In recent years, promising therapies, including immunotherapy, have emerged as leading contenders, demonstrating substantial benefits in clinical trials by inhibiting the activation of immune cells like Th1 and B cells. Furthermore, the impact of diet, gut microbiota, and metabolites on GO regulation has been recognized, suggesting the potential of non-pharmaceutical interventions. Moreover, as traditional Chinese medicine (TCM) components have been extensively explored and have shown effective results in treating autoimmune diseases, remarkable progress has been achieved in managing GO with TCM. In this review, we elucidate the pathogenesis of GO, summarize current and prospective therapies for GO, and delve into the mechanisms and prospects of TCM in its treatment.

Abstract
Purpose This study evaluated the ocular surface disease (OSD), especially dry eye disease (DED) parameters by combining qualitative and quantitative tools, including tear matrix metalloproteinase 9 (MMP-9), in patients with Graves' disease (GD) with and without Thyroid eye disease (TED). Patients and Methods A total of 17 active TED, 16 inactive TED, 16 GD without ophthalmopathy, and 16 healthy controls were included. All patients were assessed with CAS, ophthalmometry, qualitative tear MMP-9, Ocular Surface Disease Index (OSDI), ocular surface staining, Schirmer test, meibography, tear meniscus height, conjunctival hyperemia, and non-invasive tear film break-up time. Patients were classified into three subtypes of DED: aqueous tear deficiency, meibomian gland dysfunction (MGD) and mixed dry eye. Results Inactive TED was shown to be an associated factor with DED (odds ratio 14, confidence interval 2.24-87.24, p=0.0047), and presented more DED than healthy controls (87.5% versus 33.3%, p=0.0113). MGD was also more prevalent among these subjects than in healthy control (62.5% versus 6.7%; p=0.0273). No significant differences were found in other ophthalmological parameters, except for more intense conjunctival redness among active TED than GD without ophthalmopathy (p=0.0214). Qualitative MMP-9 test was more frequently positive in both eyes among active TED than in other groups (p < 0.0001). Conclusion Patients with GD were symptomatic and presented a high prevalence of ocular surface changes and DED, particularly the subgroup with inactive TED. Tear MMP-9 detection was associated with active TED suggesting a relationship between ocular surface changes and the initial inflammatory phase of ophthalmopathy.

Abstract
BACKGROUND TSH receptor autoantibodies (TRAbs) are pathognomonic for Graves' disease and are thought to also underly the pathogenesis of Graves' ophthalmopathy (GO). A decline in TRAb levels has been documented post-total thyroidectomy (TTx) in GO, however with conflicting correlations with disease outcomes. The aim of the study was to compare the effectiveness of TTx to other treatment modalities of Graves' disease and examine whether the lowering of TRAbs is associated with GO improvements. METHOD We searched electronic databases including Medline, Embase, Scopus, and Web of Science until 31 September 2022 using a broad range of keywords. Patients with GO undergoing TTx with measurements of both TRAbs and progression of the disease using a validated GO scoring system were included. Fourteen studies encompassing data from 1047 patients with GO met our eligibility criteria. The PRISMA guidelines were followed, and five studies had comparable data that were suitable for a meta-analysis. RESULTS The Cochrane Risk of Bias tool for RCTs showed low risk of bias across most domains. The pooled odds ratio showed that more patients significantly had normalized TRAb levels post-TTx as compared to other interventions (OR: 1.36, 95% CI: 1.02-1.81, p = 0.035). But, there was no significant difference in GO improvement post-TTx as compared with other intervention groups. CONCLUSIONS This meta-analysis shows that TRAb levels may decline largely post-TTx, but may not predict added improvements to the progression of GO. Thus, future studies with uniform designs are required to assess the minimal significant GO improvements.

Abstract
BACKGROUND Management of Graves' ophthalmopathy (GO) is still a challenge in Graves' disease (GD). Moreover, 40% of GD patients show radiological muscle enlargement without clinically apparent GO. Delayed treatment of GO may lead to deterioration in prognosis. METHODS Thirty GD patients with overt hyperthyroidism were included in this study, 17 of whom either had GO at diagnosis or developed GO during the study period. Samples were collected at the beginning of the study, at 6 months, and at 24 months. Plasma samples were analyzed for 92 cytokines using the Olink Target 96 inflammation panel. RESULTS After adjustment for multiplicity testing using the false discovery rate approach, soluble programmed death ligand 1 (sPD-L1) and fibroblast growth factor 23 (FGF-23) were significantly elevated in GO patients. CONCLUSION Using a broad cytokine panel we show that patients with Graves' ophthalmopathy have elevated PD-L1 and FGF-23 levels. The findings support previous suggestions that PD-L1 may serve as a treatment target.
