Prevalence of hyperthyroidism, hypothyroidism, and euthyroidism in thyroid eye disease: a systematic review of the literature.

BACKGROUND: Thyroid eye disease is an autoimmune disorder of the orbital retrobulbar tissue commonly associated with dysthyroid status. The most frequent condition is hyperthyroidism, although it is also present in hypothyroid and euthyroid patients. The prevalence of thyroid conditions in patients with thyroid eye disease had been previously evaluated; however, there is no consensus on a global prevalence. The study aims to estimate the prevalence of hyperthyroidism, hypothyroidism, and euthyroidism in patients with TED, through a systematic review of literature. METHODS: We conducted a systematic review of the literature following the PRISMA guidelines, in MEDLINE, COCHRANE, EMBASE, Science Direct, and LILACS databases. Inclusion criteria were primary studies of patients with a diagnosis of thyroid eye disease made by an ophthalmologist or with diagnosis criteria, with measurement of thyroid function (TSH, T3, and free T4), and diagnosis of the primary thyroid condition. A quality assessment was made through the Joanna Briggs Institute Quality tools. Finally, we extracted relevant details about the design, the results, and the prevalence of thyroid disorders in thyroid eye disease. RESULTS: The initial search revealed 916 studies, of which finally thirteen met inclusion criteria. Six studies were performed in Europe (Germany, Wales, and Spain), five in Asia (Iran, South Korea, Japan, and Singapore), one in North America (USA), and one in Africa (Ghana). The global prevalence, in patients of thyroid eye disease, was 10.36% for hypothyroidism, 7.9% for euthyroidism, and 86.2% for hyperthyroidism. CONCLUSIONS: Professionals should be aware that thyroid eye disease can be present in patients with a normal thyroid function. The assessment for these patients is based on orbital images; serum TSH, T3, and free T4; antibody levels as thyrotropin receptor antibodies; and thyroperoxidase levels. Additionally, we want to encourage research in this field in other regions of the world such as Latin America. SYSTEMATIC REVIEW REGISTRATION: PROSPERO ID CRD42020107167.

A cyclic vertical deviation with dysthyroid ophthalmopathy: a case report.

BACKGROUND: Cyclic strabismus is a very rare condition of ocular motility characterized by alternating strabismus and orthotropia. We report a patient with a 48-h cycle of vertical deviation associated with dysthyroid ophthalmopathy that spontaneously resolved. CASE PRESENTATION: A 40-year-old woman experienced sudden onset vertical double vision. She had already been diagnosed with hyperthyroidism. Asymmetric enlargement of the inferior and medial rectus muscles was demonstrated in her left eye on computed tomography, and was compatible with dysthyroid ophthalmopathy. She clearly described the "every-other-day" pattern of diplopia that spontaneously switched around 8 o'clock every night. She exhibited left hypotropia of 35 prism diopters on a bad day, and 7 prism diopters on a good day. CONCLUSIONS: This case illustrates that cyclic vertical deviation may spontaneously resolve along with the course of the underlying diseases that initiated the cyclic deviation, especially in patients with conditions involving motor component changes such as dysthyroid ophthalmopathy.

Change in Quality of Life after Orbital Decompression Surgery in Patients with Dysthyroid Ophthalmopathy

PURPOSE: To evaluate the effect of orbital decompression surgery on quality of life in thyroid-associated ophthalmopathy (TAO) patients. METHODS: From August 2014 to December 2015, 80 patients diagnosed with TAO at our clinic were retrospectively analyzed. The patients were divided into 2 groups: 30 patients who underwent orbital decompression surgery and 50 patients who did not receive surgery. The Korean version of the Grave's ophthalmopathy specific quality of life (GO-QoL) questionnaire was completed by all patients. We compared questionnaire scores between groups and analyzed demographic and clinical factors affecting change in GO-QoL. RESULTS: The patients who underwent orbital decompression had lower mean GO-QoL score for appearance in comparison with patients without orbital decompression (p < 0.001). The mean GO-QoL score for appearance was increased from 28.8 ± 17.1 to 51.5 ± 18.8 after orbital decompression (p = 0.024). The mean GO-QoL score for visual function was not different between the patients who did not receive surgery and the orbital decompression group. The mean GO-QoL score for visual function was not changed after orbital decompression. There was a significant relation between postoperative proptosis degree and change in GO-QoL score for appearance after orbital decompression. CONCLUSIONS: GO-QoL score for appearance was significantly improved after orbital decompression surgery, and psychological interventions should be considered to enhance the quality of life outcomes.

Oftalmopatía de Graves y tratamiento con I131 / Graves´ Ophthalmopathy and Radioiodine Treatment

La oftalmopatía de Graves (OG) es un desorden autoinmune que representa la manifestación extratiroidea más frecuente de la Enfermedad de Graves. Se describen múltiples factores que pueden influir en el desarrollo/progresión de la enfermedad, entre ellos el tratamiento con I131. El objetivo de esta monografía es analizar la bibliografía existente sobre la relación entre OG y tratamiento con I131, teniendo en cuenta su fisiopatología así como los factores de riesgo asociados y su profilaxis.

Graves´ ophthalmopathy (GO) is an autoimmune disorder representing the most common extrathyroidal manifestation of Graves' disease. Multiple factors can influence the development / progression of the disease, including treatment with 131I. The aim of this paper is to analyze the existing literature on the relationship between OG and treatment with I131, considering the pathophysiology and associated risk factors and prophylaxis.

Evaluation of Mood Disturbance in Korean Patients With Dysthyroid Ophthalmopathy

PURPOSE: to measure mood disturbance of Korean patients with dysthyroid ophthalmopathy according to the severity of ophthalmopathy. METHODS: Fifty patients with dysthyroid ophthalmopathy (mean age: 46.6+/-12.1 years; 32 female patients and 18 male patients) were included, and classified into 2 groups according to the disease severity. Twenty-five patients were classified with moderate/severe diseases (study group) and 25 patients classified with negligible/mild disease (control group). All patients completed a mood survey of 65 questions to assess differences in the degree of emotional distress. RESULTS: Analysis of each group showed that patients with moderate/severe ophthalmopathy had significantly greater emotional distress than patients with negligible/mild ophthalmopathy according to the Korean Profile of Mood States mean total score (p=0.03). In particular, patients with disfigurement (proptosis predominant group) had significantly worsen emotional distress compared with the control group (p=0.007), whereas patients with diplopia (diplopia predominant group) had no significant difference compared with the control group (p=0.60). CONCLUSIONS: Patients with moderate to severe ophthalmopathy have significant emotional distress, and severe mood disturbance especially when disfiguring signs are predominant. The psychological burden of the disease should be recognized, and routine follow-up recommended along with additional psychiatric consultation.
