Interpretation of the 2022 ETA/ATA consensus on the management of thyroid eye disease / 中华内分泌代谢杂志

In December 2022, the European Thyroid Association(ETA) and American Thyroid Association(ATA) jointly released a consensus statement on the diagnosis and management of thyroid eye disease(TED). Taking into account the benefits and risks, the consensus provides specific recommendations for essential therapeutic agents. It also covers 34 key recommendations on the diagnosis and treatment decision-making, basic therapy and care, and risk factor control for TED.

Adjunctive Middle Turbinectomy for Endoscopic Medial Orbital Wall - Thyroid Eye Disease Decompression

Abstract Introduction Middle turbinate resection (MTR) is commonly performed during endonasal endoscopic sinus and skull base surgery. Objective The purpose of this study was to characterize the additional orbital soft-tissue volume expansion during endoscopic medial orbital wall decompression with adjunctive MTR. Methods A retrospective review of patients who underwent endoscopic medial wall decompression with MTR was performed. The imaging software AW (GE Healthcare, Chicago, IL, USA) was used to overlay pre and postoperative orbital computed tomography (CT) images to visualize the preoperative position of the middle turbinate and the postoperative orbital soft tissue in the ethmoid bed. The imaging software Vitrea (Vital Images Inc., Minnetonka, MN, USA) was used to manually segment postoperative scans to determine the volume of orbital tissue which had filled the space previously occupied by the middle turbinate or medial to it. Results Nine orbits from 5 patients were included in this study; all patients were female with a history of hyperthyroidism. The average age was 55.6 years (range 32- 74). Of the 9 orbits, 7 (78%) had orbital soft tissue within the space of the resected middle turbinate postoperatively. The average volume of orbital tissue within or medial to this space was 0.83 +/- 0.67 cc. No patients had any postoperative complications. Conclusions In this patient cohort, adjunctive middle turbinate resection for endoscopic medial orbital wall decompression added ~ 0.83 cc of volume for orbital soft tissue after medial wall decompression. Middle turbinate resection is a useful adjunct to the orbital surgeon's armamentarium to augment the results of a medial orbital decompression for select patients.

A rare case of acute thyroid eye disease in a young male

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.

Clinical Study of Ocular Manifestations of Thyroid Disease in Tertiary Eye Care Center

Introduction: Thyroid eye disease (TED), Graves’ ophthalmopathy, or Thyroid associated orbithopathy (TAO) are an immunemediated inflammatory disorder that produces expansion of the extraocular muscles and fat in the orbit. TED is most commonlyassociated with Graves’ hyperthyroidism but can also be noted in hypothyroid and euthyroid states.Aim: The aim of the study is to evaluate the ocular manifestation of thyroid dysfunction (TD).Materials and Methods: A prospective non-randomized observational study was carried out on 106 patients of TD. They wereexamined in detail for demography, systemic, and ocular examination and laboratory investigation. Period of study was 1 year.Results: In this study, average age of presentation of TD was 42.54 years. Female-to-male ratio was 3.1:1. Lid retractionwas the most common (82.4%) lid sign in patients of hyperthyroidism while in patients of hypothyroidism, it was lid edema(28.9%). The second most common lid sign was lid lag which was present 70.6% cases. Proptosis was present in 52.9%hyperthyroid patients. Three patients had unilateral proptosis. Corneal ulcer (due to exposure keratopathy) was present in17.6% of hyperthyroid patients.Conclusion: Females were more commonly affected. However, ocular manifestations were more severe in male. Hence, it isimportant to rule out TD in patient with other ocular symptom.

Three Wall Orbital Decompression for Compressive Optic Neuropathy in Thyroid Ophthalmopathy / 대한이비인후과학회지

Thyroid ophthalmopathy is an autoimmune disease that affect the orbital and periorbital soft tissue, characterized by bulging eye (exophthalmos) and compressed orbital structures, such as the optic nerves. The indications for surgical treatment for thyroid ophthalmopathy include decreased visual acuity caused by optic neuropathy, conjunctivitis and progressive facial deformity caused by exophthalmos. Orbital wall decompression by nasal endoscopy resulte in good cosmetic effects and visual recovery. Balanced orbital decompression is considered to be a safe and effective surgery that can help avoid postoperative diplopia. We introduce three successful cases of orbital wall decompression for the treatment of thyroid ophthalmopathy.

A Demographic Profile And Awareness Study Of Hyperthyroidism Among Patients In A Tertiary Hospital In Western India

Background and objectives- To study the demographic profiling and awareness of hyperthyroidism among patients reporting to our hospital. Methods- A randomized retrospective study was done consisiting of 50 patients who were diagnosed with hyperthyroidism in the Out patient department of our hospital during two year period after approval by ethical committee. The data obtained were tabulated, analysed, assessed and formulated. Results- Females were more commonly affected, with age group of 60-69 being more commonly affected in the male and female category, with majority of patients belonging to the class III of kuppusamy socio-economic classification. On laterality males had more bilateral involvement with women having predominantly unilateral involvement. On treatment study, males were on a strict treatment regime as compared to their counterparts. In the socio-economic classification majority of class V category were not on any treatment. On awareness majority of male & female patients were equally unaware of the fact that they were suffering from hyperthyroidism. Conclusions- Our study showed that majority of female patients were affected, off treatment and unaware of the disease. Patients of lower socio-economic class were off treatment and unaware of the disease. As we found the group of 60-69 years were more commonly involved a thorough survey and screening of this age group is essential. With proper awareness, screening, check-ups, camps and education among we can make a remarkable difference in treatment in restoring visual function, appearance and help a reclusive patient to become socially reintegrated.

Optic Neuropathy in Thyroid Eye Disease: A Case Series / 가정의학회지

In patients with thyroid disease, ocular involvement or thyroid ophthalmopathy is common, irrespective of their thyroid status. A common feature of thyroid eye disease is eyelid retraction, which leads to a classical starry gaze (Kocher sign). Treatment with radioactive iodine (RAI) is a known therapy for hyperthyroidism. However, this treatment may lead to or worsen thyroid ophthalmopathy. We report a case series of two patients with thyrotoxicosis, who presented with an atypical and subtle occurrence of thyroid eye disease (TED) soon after RAI therapy. One of the patients was initially diagnosed and treated for dry eyes; however, over a period of time, the patient's vision progressively deteriorated. Clinical and radiological investigations confirmed thyroid ophthalmopathy with low serum thyroid hormone levels. Both patients recovered well after immediate intensive intravenous steroid treatment. These cases highlight the importance of recognizing partial ptosis as one of the presenting signs of active TED among general practitioners and physicians.

Minimally invasive surgery for thyroid eye disease.

Thyroid eye disease (TED) can affect the eye in myriad ways: proptosis, strabismus, eyelid retraction, optic neuropathy, soft tissue changes around the eye and an unstable ocular surface. TED consists of two phases: active, and inactive. The active phase of TED is limited to a period of 12–18 months and is mainly managed medically with immunosuppression. The residual structural changes due to the resultant fibrosis are usually addressed with surgery, the mainstay of which is orbital decompression. These surgeries are performed during the inactive phase. The surgical rehabilitation of TED has evolved over the years: not only the surgical techniques, but also the concepts, and the surgical tools available. The indications for decompression surgery have also expanded in the recent past. This article discusses the technological and conceptual advances of minimally invasive surgery for TED that decrease complications and speed up recovery. Current surgical techniques offer predictable, consistent results with better esthetics.

Comparison of Rebound Tonometry and Goldmann Applanation Tonometry in Restrictive Thyroid Eye Disease

PURPOSE: To compare the intraocular pressure (IOP) measured using the rebound tonometer (RT) and Goldmann applanation tonometer (GAT) in the primary position and upgaze in restrictive thyroid eye disease (TED). METHODS: We measured the IOP in 30 subjects (54 eyes) who visited an ophthalmologist between May 2014 and May 2015. This study included 16 healthy volunteers (32 eyes) and 14 TED patients (22 eyes). The outcome measurements were the comparison of IOP readings; both intergroup and 2 measurements using the RT and the GAT for patients with restrictive TED and the control group. Upgaze IOP was measured on the central cornea with a 20-degree chin-down posture. RESULTS: Both TED patients and controls showed an increase in IOP in upgaze compared with primary position (p < 0.001). There was a significant difference in mean differential IOP between patients and controls measured using RT and GAT, respectively (p < 0.001). In the control group, there was no significant difference between the 2 instrument readings in upgaze as well as primary position for patients with restrictive TED (p = 0.853 in TED; p = 0.260 in controls). CONCLUSIONS: Based on our results, the mean IOP in conventional upgaze was significantly increased in TED patients compared to primary position using both the RT and GAT and no difference in RT readings compared with GAT readings. The RT can be used to establish IOP since no significant difference between the upgaze and the primary position readings was observed in patients with restrictive TED and is a simple and effective diagnostic tool unrelated to the position and the direction of gaze.

Evaluation of Prognostic Factors and Outcomes of Single-Stage Adjustable Strabismus Surgery in Thyroid Eye Disease

PURPOSE: To evaluate the prognostic factors that contribute to favorable surgical outcomes of single-stage adjustable strabismus surgery in thyroid eye disease. METHODS: Retrospective review of clinical case notes were done of all patients who had surgical treatment for strabismus related to thyroid eye disease under the care of a single hospital between January 2005 and December 2012 (n = 30). Factors that possibly influenced the outcome were statistically analyzed for significance. "Successful" surgical outcome was defined as patients whose residual deviation was within 8 prism diopters and free from diplopia in the primary position on postoperative 1 year. RESULTS: Mean preoperative vertical deviation was 17.5 prism diopters (PD) and horizontal deviation was 20.3 PD. Mean follow-up time was 12.4 months. Twenty-four patients (80.0%) had successful surgical results. Four patients (13.3%) needed further surgery due to recurrence of previous strabismus and two patients (6.7%) needed prism glasses due to remaining strabismus. Previous history of proptosis (p = 0.02), optic neuropathy (p = 0.01), intravenous (IV) steroid pulse therapy (p = 0.02), number of times of IV steroid pulse therapy (p = 0.01), and orbital decompression surgery (p = 0.03) were different between success and failure groups. CONCLUSIONS: Single-stage adjustable strabismus surgery under topical anesthesia showed a success rate of 80% for strabismus patients with thyroid eye disease. Patients who previously had proptosis, optic neuropathy, IV steroid pulse therapy, and orbital decompression surgery significantly showed unsuccessful results after strabismus surgery.

Treatment modalities of thyroid related orbitopathy.

Aims: The aim was to highlight recent advances in the treatment of thyroid eye disease. Settings and Design: Review article. Materials and Methods: Existing literature and the authors’ experience was reviewed. Results: Thyroid ophthalmopathy is a disfiguring and vision‑threatening complication of autoimmune thyroid disease that may develop or persist even in the setting of well‑controlled systemic thyroid status. Treatment response can be difficult to predict, and optimized algorithms for disease management do not exist. Thyroid ophthalmopathy should be graded for both severity and disease activity before choosing a treatment modality for each patient. The severity of the disease may not correlate directly with the activity; medical treatment is most effective in active disease, and surgery is usually reserved for quiescent disease with persistent proptosis and/or eyelid changes. Conclusions: Intravenous pulsed corticosteroids, orbital radiotherapy, and orbital surgical techniques form the mainstay of current management of thyroid ophthalmopathy. Immunosuppressive and biologic agents may have a role in treating active disease although additional safety and efficacy studies are needed.

Orbital Morphology for Decompression Surgery in Thyroid Eye Disease Using 2-D Orbital CT and 4 Parameters

PURPOSE: To present easily measurable 2D orbit computed tomography (CT) reference data that can be used in a preoperative study for orbital decompression and classification of individual orbital morphologies. METHODS: The study sample was composed of 77 patients with orbital contusion (42 Asian males + 35 Asian females = 154 orbits) who visited the emergency room of the Korea University Guro Hospital from September 2012 to June 2013. Patients with orbital wall fracture, retrobulbar hemorrhage, or eyeball rupture were excluded. Medical records including 2D orbit or facial bone CT were retrospectively reviewed and 4 orbital parameters (orbital length, OL; globe length, GL; GL/OL ratio and 2D cone angle) were measured. RESULTS: The average OL was 42.53 +/- 2.46 mm (35.63-49.09 mm) and average GL was 24.83 +/- 1.09 mm (22.75-28.13 mm). The average GL/OL ratio using these 2 parameters was 0.59 +/- 0.04 (0.50-0.68). The posterior cone angle was on average, 45.96 +/- 5.91degrees (29.35-60.04degrees). CONCLUSIONS: Simple measurement of 4 parameters using 2D orbit CT and classification of Asian individual orbital morphology may help in the choice of the most effective surgical technique for decompression surgery in thyroid eye disease patients.

Clinical Efficacy of Blepharotomy for Upper Eyelid Retraction Associated with Thyroid Eye Disease

PURPOSE: To investigate the clinical efficacy of blepharotomy to treat upper eyelid retraction associated with thyroid eye disease. METHODS: A retrospective survey was performed with 9 eyes of 7 thyroid ophthalmopathy patients, who visited Korea University Medical Center from August 2009 to February 2011, and had undergone blepharotomy. The sex, age, change of upper eyelid retraction, postoperative complication, follow-up periods, and the surgical results were reviewed. To assess the efficacy of blepharotomy more objectively, the preoperative and postoperative pictures of patients were taken and the following lid parameters measured: marginal reflex distance 1, interpalpebral fissure height, total palpebral fissure area, upper nasal palpebral fissure area, and upper temporal palpebral fissure area. RESULTS: The mean age of patients was 37.4 years and mean follow-up period was 12.8 months. Five patients had undergone surgery unilaterally and 2 patients, bilaterally. Seven eyes of 6 patients had undergone full thickness blepharotomy and 2 eyes of 1 patient had undergone graded blepharotomy. According to the 3-month preoperative and postoperative picture analysis, all lid parameters improved significantly after blepharotomy (2.03 mm, 1.95 mm, 24.28 mm2, 12.98 mm2, and 16.21 mm2, respectively). Complications associated with blepharotomy included multiple and high folds in 2 eyes of 2 patients who had undergone full thickness blepharotomy. Re-operation was performed on only 1 eye and the result was satisfactory. CONCLUSIONS: Blepharotomy for upper eyelid retraction is a safe and highly effective surgery for upper eyelid retraction associated with symptomatic thyroid eye disease. This technique achieves excellent functional and cosmetic outcomes.

Bilateral versus unilateral thyroid eye disease.

Aims: The aim of this study was to compare demographics, clinical manifestations, associated systemic and ocular factors, severity and activity of patients with unilateral thyroid eye disease (U-TED) versus bilateral thyroid eye disease (B-TED). Materials and Methods: In a cross-sectional study, all patients with Graves’ hyperthyroidism and primary hypothyroidism seen in an endocrinology clinic were included from September 2003 to July 2006. Demographics, complete eye examination, severity score (NOSPECS, total eye score), and clinical activity score were recorded and compared in the B-TED and U-TED groups of patients. Results: From 851 patients with thyroid disorders, 303 (35.6%) had TED. Thirty-two patients (32/ 303, 10.56%) were found to have U-TED. Patients with U-TED (mean age 31.6 ± 11.6 years) were significantly younger than patients with B-TED (mean age 37.7 ± 14.7 years). Monovariate analysis (Chi-square and independent sample t-test) showed a significantly higher severity score in B-TED (U-TED 4.09±4.05, B-TED: 6.7±6.3; P= 0.002) and more activity score in B-TED (U-TED= 1.03±0.96, B-TED: 1.74±1.6, P= 0.001). However, multivariate analysis did not show any significant difference between the two groups in terms of age, gender, type of thyroid disease, duration of thyroid disease and TED, severity and activity of TED, smoking habit, and presentation of TED before or after the presentation of thyroid disease (0.1<P<1). Conclusion: This study did not find any significant difference between U-TED and B-TED in relation to the demographics, type of thyroid disease, associated findings, and severity and activity of TED.

Thyroid associated ophthalmopathy- a review

Thyroid associated ophthalmopathy is an autoimmune disorder affecting the orbital and periorbital tissues. Hyperthyroidism is commonly associated with thyroid associated ophthalmopathy, however in 5% to 10% of cases it is euthyroid. Genetic, environmental and endogenous factors play a role in the initiation of the thyroid ophthalmopathy. Smoking has been identified as the strongest risk factor for the development of the disorder. The pathogenesis involves activation of both humoral and cell mediated immunity with subsequent production of gycoaminoglycans, hyaluronic acid resulting in oedema formation, increase extraocular mass and adipogenesis in the orbit. The natural history of the disease progresses from active to inactive fibrotic stage over a period of years. Diagnosis is mainly clinical and almost all patients with ophthalmopathy exhibit some form of thyroid abnormality on further testing. Treatment is based on the clinical severity of the disease. Non-severe cases are managed by supportive measures to reduce the symptomatology and severe cases are treated by either medical or surgical decompression. Rehabilitative surgery is done for quiescent disease to reduce diplopia and improve cosmesis.

Diagnostic ability of barrett's index to detect dysthyroid optic neuropathy using multidetector computed tomography

OBJECTIVES: The objective of this study was to evaluate the ability of a muscular index (Barrett's Index), calculated with multidetector computed tomography, to detect dysthyroid optic neuropathy in patients with Graves' orbitopathy. METHODS: Thirty-six patients with Graves' orbitopathy were prospectively studied and submitted to neuro-ophthalmic evaluation and multidetector computed tomography scans of the orbits. Orbits were divided into two groups: those with and without dysthyroid optic neuropathy. Barrett's index was calculated as the percentage of the orbit occupied by muscles. Sensitivity and specificity were determined for several index values. RESULTS: Sixty-four orbits (19 with and 45 without dysthyroid optic neuropathy) met the inclusion criteria for the study. The mean Barrett's index values (± SD) were 64.47 percent ± 6.06 percent and 49.44 percent ± 10.94 percentin the groups with and without dysthyroid optic neuropathy, respectively (p<0.001). Barrett's index sensitivity ranged from 32 percent to 100 percent, and Barrett's index specificity ranged from 24 percent to 100 percent. The best combination of sensitivity and specificity was 79 percent/72 percent for BI=60 percent (odds ratio: 9.2). CONCLUSIONS: Barrett's Index is a useful indicator of dysthyroid optic neuropathy and may contribute to early diagnosis and treatment. Patients with a Barrett's index >60 percent should be carefully examined and followed for the development of dysthyroid optic neuropathy.

The Clinical Result of Somatuline(R) Therapy in Thyroid Ophthalmopathy

PURPOSE: Octreotide, a potent synthetic somatostatin (SM) analogue, was recently evaluated and found to have a beneficial effect in thyroid eye disease (TED). Lanreotide (LRT: Somatuline(R)), a new SM analogue, is more active and has a much longer duration of action. The aim of this study was to report the therapeutic effect of LRT on the treatment of TED. METHODS: Four patients of mean age 42.5 years had severe acute thyroid-related ophthalmopathy symptoms. The NOSPECS system was applied in this study to evaluate the response to treatment. They received 40 mg LRT i.m. every 2 weeks over a period of 3 months. RESULTS: All of them showed a significant improvement of acute inflammatory symptoms in both eyes. The average of TED score was 3.6, while it was 6.3 before the injection. Average clinical activity score of pre-injection was 4.1 and it markedly decreased to 1.3, and the self assessment score was 1.4, which means a moderate satisfaction. The amount of proptosis was found to decrease about 3.0 mm. CONCLUSIONS: We report our clinical experience that LRT has a beneficial effect on active TED and it is a good therapeutic modality for medical treatment.
