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.

Observational Study
Superficial ocular vascular changes after orbital decompression in patients with thyroid ophthalmopathy measured by anterior segment OCT angiography; an observational study.
Thyroid eye disease (TED) is a common ophthalmologic manifestation of thyroid dysfunction. Despite various imaging techniques available, there hasn't been a widely adopted method for assessing the anterior segment vasculature in TED patients. Our study aimed to evaluate alterations in ocular surface circulation following orbital decompression surgery in TED patients and investigate factors influencing these changes. Using anterior segment optical coherence tomography-angiography (AS-OCTA), we measured ocular surface vascularity features, including vessel density (VD), vessel diameter index (VDI), and vessel length density (VLD), both before and after decompression surgery, alongside standard ophthalmic examinations. Our AS-OCTA analysis revealed a significant decrease in most of the temporal vasculature measurements six weeks post-surgery (p < 0.05). However, differences in the nasal region were not statistically significant. These findings indicate notable changes in ocular surface circulation following orbital decompression in TED patients, which may have implications for intraocular pressure (IOP) control and ocular surface symptoms management. AS-OCTA holds promise as a tool for evaluating the effectiveness of decompression surgery and assessing the need for further interventions.

Review
Theodoros Aretaios (1829-1893), having pursued advanced studies at home and abroad and possessing a wide range of competences and interests, was among the first Greek physicians to produce educational treatises for both students and doctors of medicine. Among these is his medical treatise Surgery which deals with thyroid operations and goiter symptoms as well as post-operative lesions which included a record of his extensive experience, learned recommendations, deep insights, and advanced techniques. In this medical archive, which is preserved in the National Library of Greece, there is, for example, the physician's vivid description of a thyroidectomy that he performed which illustrates his expertise as a surgeon as well as the surgical knowledge of his times. Aretaios was not the first to perform this operation in Greece: he was, however, the first to document it, which he did for the benefit of his fellow Greeks and of surgeons worldwide.

Mucoceles can often present as a complication after prior sinus surgery or maxillofacial trauma when mucosal drainage is obstructed. Their presence in the orbit following orbital wall fracture and subsequent repair represent an exceedingly rare complication whose occurrence is limited to a few reported cases in the literature. In these patients, continuous cyst expansion and subsequent mass effect may lead to ophthalmic symptoms, including orbital pain, proptosis, diplopia, and globe dystopia. We report the discovery of an orbital mucocele after orbital floor fracture repair and its possible association with the nonporous reconstruction plate utilized for fixation. When a patient with history of orbital wall reconstruction presents with new-onset ocular symptoms, an orbital mucocele should be considered as a potential diagnosis.

Meta-Analysis Review
A meta-analysis: elucidating diagnostic thresholds of peak systolic flow velocities in thyroid arteries for the discrimination of Graves' disease and destructive thyrotoxicosis.
OBJECTIVE
This meta-analysis examines peak systolic velocities (PSVs) in thyroid arteries as potential biomarkers for thyroid disorders, which includes treated and untreated Graves' disease(GD) and destructive thyrotoxicosis(DT).
METHODS
A search across databases including PubMed, Google Scholar, Embase, and Web of Science identified studies assessing peak systolic flow velocity in the inferior thyroid artery (ITA-PSV) and superior thyroid artery (STA-PSV) diagnostic efficacy in GD and DT.And the search was restricted to publications in the English language.The analysis compared STA-PSV and ITA-PSV across patient groups, evaluating intra-group variances and synthesizing sensitivity and specificity data.
RESULTS
The analysis covered 18 studies with 1276 GD, 564 DT patients, and 544 controls. The difference of STA-PSV between GD group, DT group and normal group and the difference of ITA-PSV were analyzed in subgroups, and there was no statistical significance between subgroups when comparing any two groups. Normal subjects displayed intra-group ITA-PSV and STA-PSV differences with established cut-off values of 20.33 cm/s (95% CI, 17.48-23.18) for ITA-PSV and 25.61 cm/s (95% CI, 20.37-30.85) for STA-PSV. However, no significant intra-group differences were observed in the STA-PSV and ITA-PSV cut-off values among groups with GD or DT. The combined cut-off values for these patient groups and normal subjects were 68.63 cm/s (95% CI, 59.12-78.13), 32.08 cm/s (95% CI, 25.90-38.27), and 23.18 cm/s (95% CI, 20.09-26.28), respectively. The diagnostic odds ratio(DOR) for these values was 35.86 (95% CI, 18.21-70.60), and the area under the summary receiver operating characteristic (SROC) curve was 0.91, with a sensitivity estimate of 0.842 (95% CI, 0.772-0.866).
CONCLUSION
PSVs in thyroid arteries are useful diagnostic tools in distinguishing DT from GD. A PSV above 68.63 cm/s significantly improves GD diagnosis with up to 91% efficacy. No notable differences were found between superior and inferior thyroid arteries in these conditions.

PURPOSE
Orbital fibroblasts play key roles in the pathogenesis of Graves' orbitopathy (GO), and previous findings have shown that endoplasmic reticulum (ER) stress and autophagy also contribute to GO. In this study, we investigated the presently unclear roles of inositol-requiring enzyme 1 (IRE1) and related autophagy processes in the pro-fibrotic mechanism of GO.
MATERIALS AND METHODS
Orbital adipose/connective tissues were obtained from eight GO patients and six normal individuals during surgery. GO fibroblasts were transfected with IRE1 small-interfering RNA and treated with bafilomycin A1 (Baf-A1) to evaluate the inhibitory effects of ER stress and autophagy, and protein-expression levels were analyzed through western blotting after stimulation with transforming growth factor (TGF)-β.
RESULTS
TGF-β stimulation upregulated IRE1 in GO orbital fibroblasts, whereas silencing IRE1 suppressed fibrosis and autophagy responses. Similarly, Baf-A1, an inhibitor of late-phase autophagy, decreased the expression of pro-fibrotic proteins.
CONCLUSION
IRE1 mediates autophagy and the pro-fibrotic mechanism of GO, which provides a more comprehensive interpretation of GO pathogenesis and suggests potential therapeutic targets.

Graefe's Archive For Clinical and... Jun 2024To validate the Graves ophthalmopathy quality of life (GO-QOL) questionnaire in screening DON and to construct an effective model.
PURPOSE
To validate the Graves ophthalmopathy quality of life (GO-QOL) questionnaire in screening DON and to construct an effective model.
METHODS
A total of 194 GO patients were recruited and divided into DON and non-DON (mild and moderate-to-severe) groups. Eye examinations were performed, and quality of life was assessed by the GO-QOL questionnaire. The random forest, decision tree model, receiver operator characteristic (ROC) curve, accuracy and Brier score were determined by R software.
RESULTS
In GO-QOL, age, best corrected visual acuity (BCVA), exophthalmos, CAS, severity, and Gorman score were found to be factors related to visual function scores. On the appearance scale, gender, duration of GO, BCVA, exophthalmos, CAS and severity of GO were relevant. Both the visual function scores and appearance scores were significantly lower in DON groups than in non-DON groups (33.18 ± 24.54 versus 81.26 ± 17.39, 60.08 ± 24.82 versus 76.14 ± 27.56). The sensitivity, specificity, and AUC of the visual function scores were 91.1%, 81.7% and 0.939, respectively Visual function scores were used to construct a decision tree model. The sensitivity, specificity, and AUC of the model were 92.9%, 88.0% and 0.941, respectively, with an accuracy of 89.7% and a Brier score of 0.024.
CONCLUSIONS
Visual function scores were qualified as a screening method for DON, with a cutoff point of 58. A multifactorial screening model based on visual function scores was constructed.

Eye (London, England) Jun 2024The purpose of the study was to describe the ocular manifestations of rhabdomyosarcoma in a large cohort of children.
BACKGROUND/OBJECTIVES
The purpose of the study was to describe the ocular manifestations of rhabdomyosarcoma in a large cohort of children.
SUBJECT/METHODS
This was a retrospective observational cohort study. The medical records of all pediatric patients with head and neck rhabdomyosarcoma diagnosed between 1997 and 2021 at a tertiary-care pediatric hospital were analyzed. The main outcome measures were the incidence and prognostic role of ocular findings at presentation and long-term ocular complications.
RESULTS
There were 77 children with head and neck rhabdomyosarcoma in the study cohort with 38 patients showing ocular manifestations at presentation. Median age at diagnosis was 6.0 years, the median follow-up was 5.7 years and 54.5% were male. At last follow-up, 70.1% had no evidence of progression, 26.0% were deceased, and 2.6% were on palliative treatment. Orbital signs were common (44.2%). The most common ocular findings were proptosis (18.2%), restriction of extraocular motility (28.6%), strabismus/diplopia (22.1%) and ptosis (16.9%). The most common long-term complications were bony hypoplasia/facial asymmetry (40.3%) and keratopathy/dry eye (31.2%). Poor visual acuity (≤20/200) was noted in 13 (16.9%) patients with 5 (6.5%) patients requiring an exenteration. Survival was 100% in primary orbital RMS (p = 0.02), whereas any or a combination of cranial nerve palsies carried a poor prognosis (42% survival, p = 0.008).
CONCLUSIONS
In our cohort, half of children with rhabdomyosarcoma had ocular manifestations at presentation with about one-third showing orbital tumor involvement. Cranial nerve involvement carried a significantly worse prognosis for survival.

Review
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.

Review
PURPOSE
Histiocytosis is one of the most challenging diseases in medical practice. Because of the broad spectrum of clinical manifestations, systemic involvements, unknown etiology, and complex management, different types of histiocytosis are still a big question mark for us. Orbital histiocytosis is characterized by the abnormal proliferation of histiocytes in orbital tissues. It could affect the orbit, eyelid, conjunctiva, and uveal tract. Orbital histiocytosis can cause limited eye movement, proptosis, decreased visual acuity, and epiphora. In this study, we review the novel findings regarding the pathophysiology, diagnosis, and treatment of different types of histiocytosis, focusing on their orbital manifestations.
METHOD
This review was performed based on a search of the PubMed, Scopus, and Embase databases or relevant published papers regarding orbital histiocytosis on October 9th, 2023. No time restriction was proposed, and articles were excluded if they were not referenced in English.
RESULTS
391 articles were screened, most of them being case reports. The pathophysiology of histiocytosis is still unclear. However, different mutations are found to be prevalent in most of the patients. The diagnostic path can be different based on various factors such as age, lesion site, type of histiocytosis, and the stage of the disease. Some modalities, such as corticosteroids and surgery, are used widely for treatment. On the other hand, based on some specific etiological factors for each type, alternative treatments have been proposed.
CONCLUSION
Significant progress has been made in the detection of somatic molecular changes. Many case studies describe various disease patterns influencing the biological perspectives on different types of histiocytosis. It is necessary to continue investigating and clustering data from a broad range of patients with histiocytosis in children and adults to define the best ways to diagnose and treat these patients.
