ABSTRACT

This study aimed to investigate the effect of orbital wall decompression surgery and reduction of proptosis on the choroidal vascularity index (CVI) and subfoveal choroidal thickness (SFCT) in patients with thyroid eye disease (TED). Fifty-one eyes from 38 patients with controlled TED and proptosis were enrolled in this study. The majority of the patients (50.9%) had a clinical activity score (CAS) of zero, and none had a CAS greater than 2. The patients underwent a complete baseline ophthalmologic examination, and their choroidal profile alterations were monitored using enhanced depth imaging optical coherence tomography (EDI-OCT) before and during the three months after surgery. Changes in SFCT, luminance area (LA), total choroidal area (TCA), and the choroidal vascularity index (CVI) were measured as the ratio of LA to TCA in EDI-OCT images. The participants had an average age of 46.47 years, and 22 were female (57.9%). The SFCT of the patients exhibited a significant reduction over the follow-up period, decreasing from 388 ± 103 to 355 ± 95 µm in the first month (p < 0.001) and further decreasing to 342 ± 109 µm by the third month compared to baseline (p < 0.001). The CVI exhibited a drop from 0.685 ± 0.037 at baseline to 0.682 ± 0.035 and 0.675 ± 0.030 at 1 and 3 months post-surgery, respectively. However, these changes were not statistically significant, indicating comparable decreases in both LA and TCA. There was a significant correlation between improved proptosis and reduction in SFCT (p < 0.001) but not with CVI (p = 0.171). In conclusion, during the three months of follow-up following orbital wall decompression, CVI did not change, while SFCT reduced significantly. Additionally, SFCT was significantly correlated with proptosis reduction, whereas CVI was not.

ABSTRACT

Purpose: This study aims to report correlations between thyroid-stimulating immunoglobulin (TSI) and both clinical and radiological parameters in recent-onset symptomatic thyroid eye disease (TED) patients. Methods: A prospective cohort study of TED patients managed at the Chinese University of Hong Kong from January 2014 to May 2022. Serum TSI levels were determined with the functional assay. Outcomes included the Clinical Activity Score (CAS), marginal reflex distance1 (MRD1), extraocular muscle motility restriction (EOMy), exophthalmos, and diplopia. The radiological assessment included cross-sectional areas and signal of extraocular muscles on STIR-sequence MRI. Results: A total of 255 (197 female) treatment-naive patients, with an average onset age of 50 ± 14 years (mean ± s.d.), were included. Elevated pre-treatment TSI level was observed in 223 (88%) patients. There was a weak positive correlation between TSI and CAS (r = 0.28, P = 0.000031), MRD1 (r = 0.17, P = 0.0080), and the size of the levator palpebrae superioris/superior rectus complex (r = 0.25, P = 0.018). No significant correlation existed between TSI and STIR signals. The AUC and optimal cut-off value for clinical active TED were 0.67 (95% CI: 0.60-0.75) and 284% (specificity: 50%, sensitivity: 85%). In total, 64 patients received intravenous methylprednisolone (IVMP) during the study interval, and they had a higher baseline TSI level than those who did not have IVMP (P = 0.000044). Serial post-IVMP TSI among the 62 patients showed a significant reduction compared to the baseline level (P < 0.001). Both the baseline and post-IVMP TSI levels, and percentages of TSI changes were comparable between patients who responded and did not respond to the first course of IVMP. Conclusion: TSI can be a serum biomarker for the diagnosis, prognosis, and treatment response of TED. Further validation should be warranted.

ABSTRACT

A patient in his 20s presented with a change in the appearance of his left eye with evidence of relative afferent pupillary defect. Imaging revealed a giant frontoethmoidal osteoma, a benign sinonasal tumour, invading three-quarters of the orbit. Multidisciplinary discussion involving opthalmology, maxillofacial surgery, neurosurgery and otolaryngology resulted in the decision to attempt entirely endoscopic excision of this lesion, which was performed with successful outcomes. This case demonstrates how a sinonasal osteoma should be considered in the differential diagnosis for a patient presenting with proptosis or other eye signs suggestive of compression of the orbital compartment. This case report and literature review highlights the possibility of managing giant sinonasal osteomas with orbital extension through a completely endoscopic approach.

ABSTRACT

Immunoglobulin G4-related disease (IgG4-RD) is characterized by a systemic fibroinflammatory infiltrate that often involves the orbit in addition to other tissues. Thus it has to be considered in the differential diagnosis of orbital tumors. We report the clinical case of a 64-year-old woman who presented with right mydriasis, progressive proptosis and paralysis of the third cranial nerve of 1 year of evolution. Cranial MRI identified an intraconal lesion of the right orbit, located between the external and inferior rectus muscles and the optic nerve, and she was scheduled for surgery by transcranial approach with lateral micro-orbitomy. A satisfactory macroscopic excision was achieved with no remarkable complications and a definitive deferred histological result of pseudotumor by IgG4-RD. Follow-up for 24 months showed no tumor recurrence, and the patient clinically improved from ophthalmoplegia. This case highlights the efficacy of lateral orbitotomy in the etiologic diagnosis and successful therapeutic outcome of complex orbital lesions associated with IgG4-RD pseudotumor.

ABSTRACT

PURPOSE: To evaluate the clinical outcomes of intravenous tocilizumab (TCZ) injection in patients with moderate-to-severe active thyroid eye disease (TED). METHODS: Patients with active and moderate-to-severe TED who did not respond to conventional therapies were treated with TCZ from June 2019 to January 2021. The medical records of the patients were evaluated before the treatment. We analyzed patient demographics, including the duration of Graves' disease and TED, and assessed subjective symptoms, such as diplopia and ocular movement, clinical activity score (CAS), modified NOSPECS score, and exophthalmos before treatment and at 4, 8, 12, and 16 weeks after the first drug injection. Blood tests, including TSH Rc Ab and TS Ab, were performed before treatment and 24 weeks after the first injection. And orbital computed tomography (CT) was performed and Barrett's Index was calculated at baseline and after completion of all injections. RESULTS: Nineteen completed the scheduled treatment. There were no significant side effects, other than herpes zoster in one case and headache and dermatitis in another. Clinical symptoms before and 16 weeks after the treatment showed mean CAS decreased by 2.4 points, mean modified NOSPECS score decreased by 3.7 points, and mean exophthalmos decreased by 0.4 mm. Diplopia and extraocular muscle limitation improved in ten and remained stationary in five of the 15 patients, who presented with extraocular motility abnormalities. Six of 11 patients who underwent orbit CT showed improvement in muscle size. The mean TSH Rc Ab decreased by 7.5 IU/L and TS-Ab decreased by 162.9%. CONCLUSION: TCZ can treat active moderate-to-severe TED, showing high drug compliance and reasonable response to inflammation and extraocular motility abnormality.

ABSTRACT

BACKGROUND: Graves' disease is the autoimmune activation of the thyroid gland causing diffuse enlargement and hyperfunction of the gland. Manifestations of Graves' disease are multisystemic and include thyroid orbitopathy; pretibial myxedema, also referred to as thyroid dermopathy; and thyroid acropachy, described as a severe form of thyroid dermopathy. Our paper focuses on an atypical case of thyroid dermopathy. CASE PRESENTATION: An 11-year-old Saudi male presented with a prominent diffuse goiter and exophthalmos. Investigations were consistent with a diagnosis of Graves' disease. The physical exam showed diffuse, non-pitting swelling of the ankle and penis, mimicking a lymphatic malformation. Further, multiple nodules were found on the hands and feet. Treatment of the nodules with cautery resulted in more severe nodules. CONCLUSION: This report describes rare presentations of thyroid dermopathy mimicking lymphatic malformation. The Koebner phenomenon can explain this patient's atypical presentations. Intralesional injections of triamcinolone and total thyroidectomy showed clear improvement.

ABSTRACT

PURPOSE: Patients with thyroid eye disease (TED) can present with asymmetric disease. The purpose of this study was to evaluate the prevalence of asymmetric TED in an Australian cohort and investigate clinical, biochemical, and radiological associations of asymmetric TED. METHODS: This was a retrospective study of patients with TED who underwent Hertel exophthalmometry and orbital computed tomography (CT) scans. Asymmetry was defined as a difference in the globe protrusion of ≥ 3 mm using Hertel exophthalmometry. Data was collected on patient demographics, clinical disease presentation, thyroid function tests and antibody levels. Muscles volumes were determined by manually segmenting the extraocular muscles on CT scans using a commercially available software. RESULTS: 172 orbits from 86 patients were included in the study. 28 (33%) patients had asymmetric TED. No significant differences were observed in age, gender, thyroid hormone status, anti-thyroid peroxidase levels, thyroid stimulating hormone receptor antibodies, disease activity status, or dysthyroid optic neuropathy between the asymmetric and non-asymmetric groups. The extraocular muscle volumes were significantly higher in the asymmetric orbit compared to its contralateral orbit. CONCLUSION: Asymmetric TED is a reasonably common occurrence in the course of TED. It is associated with higher extraocular muscle volumes, suggesting muscle enlargement as one of the underlying contributors to asymmetric proptosis. Thyroid eye disease should be considered in the differential of asymmetric orbital inflammatory disease.

ABSTRACT

Raine syndrome (RNS) is a rare autosomal recessive osteosclerotic dysplasia. RNS is caused by loss-of-function disease-causative variants of the FAM20C gene that encodes a kinase that phosphorylates most of the secreted proteins found in the body fluids and extracellular matrix. The most common RNS clinical features are generalized osteosclerosis, facial dysmorphism, intracerebral calcifications and respiratory defects. In non-lethal RNS forms, oral traits include a well-studied hypoplastic amelogenesis imperfecta (AI) and a much less characterized gingival phenotype. We used immunomorphological, biochemical, and siRNA approaches to analyze gingival tissues and primary cultures of gingival fibroblasts of two unrelated, previously reported RNS patients. We showed that fibrosis, pathological gingival calcifications and increased expression of various profibrotic and pro-osteogenic proteins such as POSTN, SPARC and VIM were common findings. Proteomic analysis of differentially expressed proteins demonstrated that proteins involved in extracellular matrix (ECM) regulation and related to the TGFß/SMAD signaling pathway were increased. Functional analyses confirmed the upregulation of TGFß/SMAD signaling and subsequently uncovered the involvement of two closely related transcription cofactors important in fibrogenesis, Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ). Knocking down of FAM20C confirmed the TGFß-YAP/TAZ interplay indicating that a profibrotic loop enabled gingival fibrosis in RNS patients. In summary, our in vivo and in vitro data provide a detailed description of the RNS gingival phenotype. They show that gingival fibrosis and calcifications are associated with, and most likely caused by excessed ECM production and disorganization. They furthermore uncover the contribution of increased TGFß-YAP/TAZ signaling in the pathogenesis of the gingival fibrosis.

ABSTRACT

OBJECTIVE: This study aimed to identify factors affecting proptosis recovery in spheno-orbital meningioma (SOM) surgery and assess functional and oncological outcomes. METHODS: Data from 32 consecutive SOM surgery cases (2002-2021) were analyzed. Clinical, radiological, operative, and oncological parameters were examined. Proptosis was assessed using the exophthalmos index (EI) on MRI or CT scans. Statistical analyses were performed to identify predictive factors for proptosis recovery. RESULTS: Proptosis improved in 75% of patients post-surgery (EI decreased from 1.28 ± 0.16 to 1.20 ± 0.13, p = 0.048). Patients with stable or worsened EI had higher body mass index (28.5 ± 7.9 vs. 24.1 ± 4.7, p = 0.18), Simpson grade (IV 75% vs. 65%, p = 0.24), and middle sphenoid wing epicenter involvement (63% vs. 38%, p = 0.12), but no significant factors were associated with unfavorable exophthalmos outcomes. The improvement group had higher en plaque morphology, infratemporal fossa invasion, and radiation treatment for cavernous sinus residual tumor (88% vs. 75%, p = 0.25; 51% vs. 25%, p = 0.42; 41% vs. 25%, p = 0.42, respectively), but without statistical significance. Visual acuity remained stable in 78%, improved in 13%, and worsened in 9% during follow-up. Surgery had a positive impact on preoperative oculomotor nerve dysfunction in 3 of 4 patients (75%). Postoperative oculomotor nerve dysfunction was observed in 25%, of which 75% fully recovered. This occurrence was significantly associated with irradiation of an orbital tumor residue (p = 0.04). New postoperative trigeminal hypoesthesia was observed in 47%, of which 73% recovered. All SOMs were classified as WHO grade 1, and complementary treatments achieved oncological control, requiring gamma-knife radiosurgery in 53% and standard radiotherapy in 6%. CONCLUSIONS: Surgery effectively improves proptosis in SOM, though complete resolution is rare. The absence of predictive factors suggests multifactorial causes, including body mass index and tumor resection grade. Postoperative oculomotor nerve dysfunction and trigeminal hypoesthesia are common but often recover. Gamma-knife radiosurgery maintains long-term oncological control for evolving tumor residue.

ABSTRACT

Este manuscrito presenta un caso de un leiomioma orbitario de larga evolución en un joven de 14años. El tumor era inusualmente grande y causaba una proptosis severa y una afectación importante de la musculatura ocular. El paciente presentaba amaurosis, una oftalmoplejía completa, dolor ocular espontáneo e incapacidad para cerrar los párpados. Debido al tamaño del tumor y a su progresión, se realizó una exenteración orbitaria derecha para eliminar todo el contenido orbitario, incluyendo el tumor y el globo ocular. El procedimiento quirúrgico tenía como objetivo prevenir la recurrencia del tumor y mejorar la calidad de vida del paciente. El análisis histopatológico confirmó el diagnóstico de leiomioma orbitario. Este caso presenta un interés particular por el grado de evolución que ha alcanzado. La extirpación completa del tumor y un seguimiento a largo plazo son necesarios para prevenir la recurrencia y garantizar resultados óptimos para el paciente. Además, este caso refleja las grandes diferencias en el acceso a la sanidad en las diferentes regiones del mundo. (AU)


This manuscript describes an exceptional case of a long-standing orbital leiomyoma in a 14-year-old male. The tumor was unusually large, causing severe proptosis and significant involvement of the ocular muscles. The patient presented with amaurosis, complete ophthalmoplegia, spontaneous eye pain, and the inability to close the eyelids, leading to psychological distress. Due to the tumor's size and progression, a right orbital exenteration was performed to remove all orbital contents, including the tumor and the eyeball. The surgical procedure aimed to prevent tumor recurrence and improve the patient's quality of life. The histopathological analysis confirmed the diagnosis of orbital leiomyoma. This case presents a particular interest due to the degree of evolution it has reached. Complete tumor excision and long-term follow-up are necessary to prevent recurrence and ensure optimal patient outcomes. This report underscores global healthcare disparities and the complexity of managing rare orbital neoplasms in diverse country settings. (AU)

ABSTRACT

This study aimed to assess the feasibility of utilizing a surgical guide, designed through digital medical technology, in lateral orbital decompression surgery. METHODS: In total, 18 patients with thyroid-associated ophthalmopathy (TAO), who underwent orbital balance decompression surgery at the Affiliated Eye Hospital of Nanchang University between September 2018 and August 2022, were included. Orbital CT scanning was performed on all patients with TAO, and Mimics 21.0 software was used to reconstruct a three-dimensional model of the orbit based on the CT data. The osteotomy guide plate for lateral orbital decompression surgery was designed using 3-matic 13.0 software, adhering to the criteria of surgical effectiveness and safety. The surgical positioning guide was designed using Geomagic Wrap 21.0. Once printed, the surgical guide was sterilized with low-temperature plasma and applied during surgery. Of the nine patients treated using a surgical navigation system, three cases experienced cerebrospinal fluid leakage complications during the procedure, and two exhibited inadequate bone removal along the lateral wall. In contrast, among the nine patients treated with surgical guides, no intraoperative cerebrospinal fluid leakage or evidence of insufficient lateral wall bone removal was observed, highlighting a statistically significant distinction between the two cohorts (p = 0.046). Postoperative improvements were notable in best-corrected visual acuity (BCVA) and exophthalmos for patients afflicted with extremely severe TAO. The surgical guide, designed with digital medical technology, has been shown to be an effective and secure auxiliary tool in lateral orbital decompression surgery. It not only aids in reducing the incidence of intraoperative complications, but also enhances the accuracy and safety of surgery. These improvements offer robust support for continued exploration in this field within clinical practice.

ABSTRACT

Superior ophthalmic vein thrombosis is a rare condition scarcely described in clinical literature with potentially severe consequences including permanent vision loss. This report details the case of a 70-year-old woman who presented with acute binocular horizontal diplopia, relative proptosis of the OD by 4 mm, and pain OD. On exam, visual acuity was 20/20 OD and 20/30 OS with full extraocular movements. CT revealed proptosis OD with a thrombosed superior ophthalmic varix. Evaluation for etiology of hypercoagulability was unremarkable, although the patient did have an asymptomatic COVID-19 infection 1 month prior. To the authors' knowledge, this is the first reported case of superior ophthalmic vein thrombosis secondary to an asymptomatic COVID-19 infection.

ABSTRACT

PURPOSE: We aimed to study reported cases of nasopharyngeal carcinoma presenting with ophthalmic manifestations with and without a prior diagnosis of nasopharyngeal carcinoma. METHODS: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A literature search was conducted using the MEDLINE database in PubMed and Google Scholar. We included patients with a previous diagnosis of nasopharyngeal carcinoma in Group I and those without a prior diagnosis of nasopharyngeal carcinoma in Group II. Data included demographics, clinical presentation, history of nasopharyngeal carcinoma, treatment, histopathological description, World Health Organization classification, and outcome. RESULTS: Fifty-eight patients (26 in Group I and 32 in Group II) were included. The male-to-female ratio was 3:1. The mean age of the patients (53.3 ± 11.7 years and 54.8 ± 16.2 years, respectively) and gender did not differ significantly between the two groups. The most common ocular presentations were diplopia and proptosis in the first group (each in 34.6%), whereas visual disturbance was most common in the second group (46.9%). Treatment options and World Health Organization grading were comparable. The outcome in 38 patients (after a comparable follow-up period) was significantly better in group II (p=0.003). There was no statistically significant difference in the outcome of 23 patients in correlation with World Health Organization grades II versus III irrespective of group (p=0.094). CONCLUSIONS: The demographics of patients with nasopharyngeal carcinoma presenting with ophthalmic manifestations were similar between the two study groups, with a wide age range and male predominance. Patients presenting initially to ophthalmologists with no history of nasopharyngeal carcinoma have a more favorable outcome. World Health Organization grading may have less value as a prognostic indicator.

ABSTRACT

BACKGROUND: This study aims to compare the changes in ophthalmic parameters among syndromic craniosynostosis patients who underwent craniofacial skeletal expansion procedures via distraction osteogenesis (DO). METHOD: A retrospective study was conducted involving syndromic craniosynostosis patients who underwent surgical expansion via the DO technique from the year 2012 to March 2022. Changes in six parameters which consist of visual acuity, refractive error, optic disc health, intraocular pressure, degree of proptosis and orbital volume were measured objectively pre and post-surgery. For categorical parameters, the Chi-square cross-tab test was done. Paired sample T-test was used for normally distributed variables. Wilcoxon signed-rank test was used for non-normally distributed data. RESULTS: Visual impairment was present in 21.4% of eyes before surgery and increased to 28.5% post-surgery. Three patients had changes of refractive error post-surgery with one developed hypermetropia, another developed anisometropia and the last had improvement to no refractive error. Two patients had optic disc swelling which was resolved post-surgery. Intraocular pressure changes were inconsistent post-surgery. All patients achieved a significant reduction in the degree of proptosis post-surgery. Orbital volume calculation using computed tomography (CT) scans shows a significant increase in volume post-surgery for all patients. CONCLUSION: Our study shows a significant increase in orbital volume post-surgery with a reduction in the degree of proptosis. Optic disc and nerve health improved after the surgery. Changes in terms of visual acuity, refractive error and IOP were inconsistent after the surgical intervention.

ABSTRACT

BACKGROUND: Orbital ischemic syndrome is a rare entity. The clinical signs typically demonstrate acute loss of visual acuity, chemosis, proptosis, ptosis, and total ophthalmoparesis. We report a case of a man who suffered an acute internal carotid artery occlusion and developed orbital ischemic syndrome after a mechanical thrombectomy. CASE PRESENTATION: A 57-year-old Vietnamese (Kinh ethnicity) man was brought to the emergency room with complaints of a speech disturbance, facial palsy, and severe weakness of the left arm and leg, which had started 4 hours earlier, after waking up. The National Institutes of Health Stroke Scale 12 (NIHSS 12) revealed the neurological score at admission. A head computed tomography scan showed no intracranial bleeding and an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) of 8 on the right brain. Computed tomography angiography showed an occlusion of the right internal carotid artery. After that, a mechanical thrombectomy was performed, and the internal carotid artery was completely reperfused. After 10 hours, he experienced orbital pain, proptosis, ptosis, chemosis, and ophthalmoplegia of the right orbit. He also had acute loss of visual acuity, and fundoscopic examination revealed papilledema, no retinal hemorrhage, and no bruit in orbital auscultation. Intraocular pressure in the right eye was measured at 50.5 mmHg. Computed tomography angiography showed no carotid-cavernous fistula, but slight enlargement of the right medial and lateral rectus muscles. He was treated with steroids and hyperosmolar agents and recovered 7 days later, but had persistent loss of visual acuity in the right eye. CONCLUSION: Orbital ischemic syndrome is a rare complication after mechanical thrombectomy treatment in acute ischemic stroke that can lead to loss of visual acuity.

ABSTRACT

The host environment is of critical importance for antibiotic efficacy. By impacting bacterial machineries, stresses encountered by pathogens during infection promote the formation of phenotypic variants that are transiently insensitive to the action of antibiotics. It is assumed that these recalcitrant bacteria-termed persisters-contribute to antibiotic treatment failure and relapsing infections. Recently, we demonstrated that host reactive nitrogen species (RNS) transiently protect persisters against the action of ß-lactam antibiotics by delaying their regrowth within host cells. Here, we discovered that RNS intoxication of persisters also collaterally sensitizing them to fluoroquinolones during infection, explaining the higher efficiency of fluoroquinolones against intramacrophage Salmonella. By reducing bacterial respiration and the proton-motive force, RNS inactivate the AcrAB efflux machinery of persisters, facilitating the accumulation of fluoroquinolones intracellularly. Our work shows that target inactivity is not the sole reason for Salmonella persisters to withstand antibiotics during infection, with active efflux being a major contributor to survival. Thus, understanding how the host environment impacts persister physiology is critical to optimize antibiotics efficacy during infection.

ABSTRACT

This manuscript describes an exceptional case of a long-standing orbital leiomyoma in a 14-year-old male. The tumor was unusually large, causing severe proptosis and significant involvement of the ocular muscles. The patient presented with amaurosis, complete ophthalmoplegia, spontaneous eye pain, and the inability to close the eyelids, leading to psychological distress. Due to the tumor's size and progression, a right orbital exenteration was performed to remove all orbital contents, including the tumor and the eyeball. The surgical procedure aimed to prevent tumor recurrence and improve the patient's quality of life. The histopathological analysis confirmed the diagnosis of orbital leiomyoma. This case presents a particular interest due to the degree of evolution it has reached. Complete tumor excision and long-term follow-up are necessary to prevent recurrence and ensure optimal patient outcomes. This report underscores global healthcare disparities and the complexity of managing rare orbital neoplasms in diverse country settings.
