RESUMO

Introducción: La oftalmopatía tiroidea (OT) es un trastorno debilitante en pacientes con enfermedad tiroidea autoinmune, principalmente enfermedad de Graves, que se desarrolla entre el 30 a 50% de los casos. Objetivos: Describir las características clínico-oftalmológicas y la evolución de los pacientes con oftalmopatía tiroidea activa moderada severa tratados con bolos de metilprednisolona que acuden al Hospital Central del Instituto de Previsión Social en el tiempo comprendido entre enero de 2018 y setiembre de 2021. Materiales y métodos: Investigación de diseño observacional, con estudio descriptivo, retrospectivo. Resultados: Se revisaron fichas de 34 pacientes con OT activa moderada severa que recibieron bolos de metilprednisolona basado en las guías EUGOGO 2016, de los cuáles se excluyeron 3 pacientes por tener fichas incompletas y otros 3 pacientes ya que requirieron tratamiento de segunda línea previo al término del esquema de 12 sesiones. De los 28 pacientes estudiados, la edad promedio fue de 43,6 ±13,1 años, el 89% de sexo femenino y el 28,5%, fumadores. En cuanto a la función tiroidea de la población previo al tratamiento, se constató hipertiroidismo en el 82%, hipotiroidismo en el 11% y eutiroidismo en el 7%; y posterior al tratamiento, se constató hipertiroidismo en el 78,6% (subclínico), eutiroidismo en el 17,9% e hipotiroidismo en el 3,5%. La mayoría (92.6%) contaba con anticuerpos contra el receptor de TSH positivo, con un promedio de 18 ± 9,9 mIU/Ml. Respecto a la actividad de la oftalmopatía según la escala CAS, se constató un promedio de 4,1 ±1,0 previo al tratamiento y posterior 1,2 ±1,4; de ellos el 46,4% presentó un estado leve según escala de gravedad, 39% sin criterios de gravedad y 14 % persistió en moderada -severa. Se constató mejoría de la agudeza visual tras el tratamiento (57,1%), el promedio de exoftalmía previo al tratamiento fue 22,2 mm y posterior 21,1 mm; se presentó diplopía en el 7,1% previo al tratamiento y en el 3,6% posterior al tratamiento. Conclusión: El tratamiento con glucocorticoides endovenosos en la oftalmopatía de Graves moderada-severa (esquema EUGOGO 2016) fue muy efectivo, revirtiendo la actividad y consecuentemente ayudando a disminuir la gravedad, en la gran mayoría de nuestros pacientes. Esto podría explicarse porque la oftalmopatía era incipiente y por el alto grado de adherencia de los pacientes en el contexto de un manejo multidisciplinar bien protocolizado.

Introduction: Graves' orbitopathy (GO) is a debilitating disorder in patients with autoimmune thyroid disease, mainly Graves' disease, which develops in 30 to 50% of cases. Objectives: To describe the clinical-ophthalmological characteristics and evolution of patients with moderate-to- severe active GO treated with methylprednisolone boluses who attended the Central Hospital of the Institute of Social Security between January 2018 and September 2021. Materials and methods: Observational design research, descriptive, retrospective study. Results: Records of 34 patients with active moderate-to-severe GO who received boluses of methylprednisolone based on the EUGOGO 2016 guidelines, were reviewed, of which 3 patients were excluded due to having incomplete records and another 3 patients since they required second-line treatment prior to end the 12-session scheme. Of the 28 patients studied, the average age was 43.6 ±13.1 years, 89% were female and 28.5% were smokers. Regarding the thyroid function of the population prior to treatment, hyperthyroidism was found in 82%, hypothyroidism in 11% and euthyroidism in 7%; and after treatment, hyperthyroidism was found in 78.6% (subclinical), euthyroidism in 17.9% and hypothyroidism in 3.5%. The majority (92.6%) had positive thyrotropin receptor antibodies, with an average of 18 ± 9.9 mIU/Ml. Regarding the activity of orbitopathy according to the CAS scale, an average of 4.1 ±1.0 was found before treatment and 1.2 ±1.4 after; Of them, 46.4% presented a mild condition according to the severity scale, 39% without severity criteria and 14% persisted in moderate-severe. Improvement in visual acuity was noted after treatment (57.1%), the average exophthalmia before treatment was 22.2 mm and after 21.1 mm; Diplopia occurred in 7.1% before treatment and in 3.6% after treatment. Conclusion: Treatment with intravenous glucocorticoids in moderate-severe Graves' orbitopathy (EUGOGO 2016 scheme) was very effective, reversing the activity and consequently helping to reduce the severity, in the vast majority of our patients. This could be explained because the orbitopathy was incipient and by the high degree of patient adherence in the context of well-protocolized multidisciplinary management.

RESUMO

La orbitopatía asociada al tiroides es la primera causa de afección inflamatoria orbitaria y de exoftalmo en adultos. Su progresión puede generar complicaciones, las cuales, ante un manejo inoportuno u omisión diagnóstica, pueden conllevar a disfunción visual irreversible. De aquí la importancia de garantizar un diagnóstico y tratamiento adecuados, para lo cual es fundamental un correcto manejo imagenológico. Con el propósito de actualizar y sistematizar el conocimiento sobre el diagnóstico por imágenes de la orbitopatía asociada al tiroides, se realizó una revisión de las publicaciones relacionadas con el tema de las últimas dos décadas. La búsqueda y la localización de la información se apoyaron en la elección de palabras clave/descriptores que configuraron su perfil. Además, se analizaron las ecografías, tomografías computarizadas y resonancias magnéticas de los pacientes diagnosticados con esta enfermedad en el Instituto Cubano de Oftalmología Ramón Pando Ferrer, durante los últimos 10 años. Todo lo investigado confirma que las técnicas de imagen son claves para establecer el diagnóstico de la oftalmopatía asociada al tiroides, pero jamás sustituirán a la historia clínica detallada y el examen físico minucioso. El médico se equivoca gravemente cuando pretende obviar la importancia del juicio clínico. La omisión de este principio, en el mejor de los casos, solo conducirá a diagnósticos casuales(AU)

Thyroid-associated orbitopathy is the leading cause of orbital inflammatory disease and exophthalmos in adults. Its progression can generate complications, which, in case of inopportune management or diagnostic omission, can lead to irreversible visual dysfunction. Hence the importance of guaranteeing an adequate diagnosis and treatment, for which a correct imaging management is essential. With the purpose of updating and systematizing the knowledge on the imaging diagnosis of thyroid associated orbitopathy, a review of the publications related to the subject of the last two decades was carried out. The search and localization of the information was supported by the choice of keywords/descriptors that configured its profile. In addition, ultrasound scans, CT scans and MRI scans of patients diagnosed with this disease at the Cuban Institute of Ophthalmology Ramón Pando Ferrer, during the last 10 years, were analyzed. All that has been investigated confirms that imaging techniques are key to establish the diagnosis of thyroid-associated ophthalmopathy, but they will never replace a detailed clinical history and a thorough physical examination. The physician is seriously mistaken when he pretends to ignore the importance of clinical judgment. The omission of this principle will, at best, only lead to casual diagnoses(AU)

RESUMO

PURPOSE: The purpose of the study was to measure the effect of rim-off deep lateral decompression for Graves orbitopathy on the lateral rectus muscle path and oculomotor balance. METHODS: Retrospective analysis of the medical records and pre- and postoperative computed tomography scans of 34 orbits of 23 patients who underwent deep lateral decompression alone. The oculomotor balance of these 23 patients was measured with the alternate cover test and prisms before and after surgery. Bezier functions were used to measure the postoperative path of the lateral rectus in all decompressed orbits. RESULTS: Deep lateral decompression induced a curvilinear deformation of the lateral rectus. There was no significant correlation between the position of the point of maximum muscle displacement and the size of the residual lateral wall. The changes in the lateral rectus path had no adverse effects on the oculomotor balance of the patients. CONCLUSIONS: The location of the curvilinear deformation of the lateral rectus does not depend on the residual segment of the lateral wall. The changes of the lateral rectus path have no deleterious effect on the oculomotor balance.

RESUMO

Se comunica una serie de tres casos clínicos que consultaron al servicio de Reumatología por compromiso orbitario y renal. Uno de ellos presentó pseudotumor orbitario con proteinuria en rango nefrótico; se realizó biopsia y se encontró infiltrado linfoplasmocitario denso y fibrosis estoriforme con inmunohistoquímica: 15 células IgG4+ por campo de alto poder y relación IgG/IgG4 ≤40%, concluyendo diagnóstico de enfermedad relacionada por IgG4. El segundo y tercer caso presentaron compromiso ocular con "ojos de mapache" y lesiones amarillentas en párpados, ambos con proteinuria >500 mg/24 h, con biopsia de piel rojo Congo positiva y birrefringencia verde manzana con luz polarizada. Se discuten distintos diagnósticos diferenciales poco frecuentes a tener en cuenta en estos pacientes.

A series of three cases that consulted the rheumatology service due to orbital and renal involvement is reported. One of them presented orbital pseudotumor with proteinuria in the nephrotic range, a biopsy was performed, finding dense lymphoplasmacytic infiltrate and storiform fibrosis with immunohistochemistry: 15 IgG4 positive cells per HPF and IgG/IgG4 ratio ≤40%, concluding diagnosis of IgG4 related disease. The second and third cases presented ocular involvement with raccoon eyes and yellowish lesions on the eyelids, both with proteinuria greater than 500 mg/24 h, with apple-green birefringence of amyloid on congo red staining. Different rare differential diagnoses to take into account in these patients are discussed.

RESUMO

OBJECTIVE: Graves' disease (GD) is the main cause of hyperthyroidism among adults. It is an autoimmune condition classically marked by the Merserburg Triad (goiter, thyrotoxicosis, and orbitopathy), but the change in presentation of GD over time has rarely been studied. To determine changes in the clinical presentation of patients with GD in the last 30 years. METHODS: The study evaluated 475 patients diagnosed with GD between 1986 and 2016 in a single center. Patients were evaluated regarding epidemiological aspects, thyroid function, inflammatory activity of the eyes evaluated by the Clinical Activity Score; CAS, severity evaluated by NOSPECS classification and thyroid volume estimated by ultrasonography. RESULTS: Patients assessment identified an increase in the mean age of diagnosis of GD (p < 0.02), a reduction in thyroid volume (p < 0.001) and less intense orbital involvement from 2007-2016 compared to 1986-2006 (p = 0.04). The number of smoking patients was smaller from 2007 to 2016 (28.7%) than 1986 to 2006 (42.8% p = 0.001). The TSH and TRAb values did not had significant changes. CONCLUSION: GD presentation appears to be changed in the last years compared to the typical initial presentation. There is a less frequent inflammatory involvement of orbital tissue, smaller goiters, a lower number of smokers and diagnosis at older age.

RESUMO

BACKGROUND: Graves' orbitopathy (GO) is the most common extrathyroidal manifestation of Graves' disease (GD), an autoimmune disorder arising from the activity of T lymphocytes against antigens that infiltrate thyroid tissue, orbital tissue and extraocular muscles. An increase in oxidative stress has been discovered in autoimmune thyroid disease, encouraging investigation into new forms of treatment. Selenium has been described as a treatment option given its antioxidant properties. The present study evaluates the decrease of progression and inflammatory signs in patients with mild GO with oral selenium supplementation. METHODS: Controlled, randomized, single center trial at an ophthalmology referral center in Mexico City. Patients at least 18years of age with mild GO according to the CAS classification were included; exclusion criteria in addition to corticosteroid treatment included smokers or selenium allergy. Each patient was randomized into one of two groups. Group A took placebo tablets which consisted of 100µg of starch twice a day for 6months, and group B took a 100µg selenium tablet twice a day for 6months. The patients from both groups were examined and evaluated using a CAS score before and after the first, third and sixth month of treatment. RESULTS: Thirty eyes of 30 patients were studied. The pretreatment values showed no statistically significant differences between groups (P>0.05). Intergroup analysis showed statistically significant differences in palpebral fissure and CAS score between the pretreatment values and six months after treatment in the selenium group (P<0.05). No differences were found in any variables in the placebo group during the study period (P>0.05). No adverse events were reported. CONCLUSIONS: This is the first study in a Mexican population demonstrating that oral selenium decreases clinical activity and stops progression in patients with mild GO.

RESUMO

PURPOSE: To assess the sensitivity and specificity of lateral midpupil lid distances for the detection of upper lid lateral flare. METHODS: Lateral lid flare was determined by unanimous agreement among six experienced oculoplastic surgeons in the grading of photographs obtained for patients with Graves orbitopathy (GO). Bézier lines were employed to extract the upper eyelid contours of the patients and a control group of age and sex matched subjects. Custom software was employed to determine 5 lateral midpupil eyelid distances. The sensitivity and specificity of each measurement in detecting lateral flare were estimated from receiver operating characteristic curves. The non-parametric Kruskal-Wallis one-way analysis of variance (ANOVA) with Dunn's posthoc test was used to compare the median values of the contour parameters between groups. RESULTS: The degree of agreement between judges evaluated with the Fleiss' Kappa test was relatively high (K = 0.69, z = 16.6, p < .0001). The raters classified 12 lids with lateral lid flare (LLF) and 7 without LLF in patients with GO. There was no agreement on the presence or absence of LLF in 11 lids. In all eyes, lateral midpupil lid distances diminished from the center of the eyelid towards the lateral canthus. Receiver operating characteristic analysis for the midpupil distances revealed that the fourth distance from the center demonstrated high sensitivity and specificity in detecting flare. At this location (2.5 mm medial to the lateral canthus) a midpupil distance equal to or greater than 60% of the margin reflex distance (MRD1) indicated the presence of flare. CONCLUSIONS: - A single measurement of a lateral midpupil eyelid distance 2.5 mm medial to the lateral canthus is a sensitive and specific measurement for the diagnosis of the LLF.

RESUMO

PURPOSE: To systematically review the literature on the deep lateral orbital decompression (DLD). METHODS: The authors searched the MEDLINE, Lilac, Scopus, and EMBASE databases for all articles in English, Spanish, and French that used as keywords the terms orbital decompression and lateral wall. Two articles in German were also included. Data retrieved included the number of patients and orbits operated, types of the approach employed, exophthalmometric and horizontal eye position changes, and complications. The 95% confidence intervals (CI) of the mean Hertel changes induced by the surgery were calculated from series with 15 or more data. RESULTS: Of the 204 publications initially retrieved, 131 were included. Detailed surgical techniques were analyzed from 59 articles representing 4559 procedures of 2705 patients. In 45.8% of the reports, the orbits were decompressed ab-interno. Ab-externo and rim-off techniques were used in 25.4% and 28.8% of the orbits, respectively. Mean and 95% CI intervals of Hertel changes, pooled from 15 articles, indicate that the effect of the surgery is not related to the technique and ranges from 2.5 to 4.5 mm. The rate of new onset of diplopia varied from zero to 8.6%. Several complications have been reported including dry eye, oscillopsia, temporal howling, lateral rectus damage, and bleeding. Unilateral amaurosis and subdural hematoma have been described in only one patients each. CONCLUSIONS: The low rate of new-onset diplopia is the main benefit of DLD. Prospective studies are needed to compare the rate of complications induced by the 3 main surgical techniques used.

RESUMO

PURPOSE: To describe pre- to post-treatment changes in clinical activity score (CAS) and exophthalmometry in patients with Graves orbitopathy treated with tocilizumab (TCZ). MATERIAL AND METHODS: Eight Mexican patients presenting with active Graves orbitopathy (CAS>3/7) previously treated with glucocorticoids received 1 monthly dose of TCZ for 6 months. CAS, EUGOGO severity assessment and exophthalmometry were used to evaluate clinical status, with serum measurement of thyroid-stimulating hormone receptor antibodies (TR-Ab) for biochemical evaluation before and after application of TCZ. RESULTS: Eight patients were analyzed: 6 male (75%), 2 female (25%): mean age, 45.9±11.2 years; mean weight, 85±18.3 kg. Mean TR-Ab level at treatment outset was 291.9±96.4%, mean CAS 4.1±0.3 and mean exophthalmometry 21.2±3.2 mm. After TCZ treatment, mean TR-Ab level fell to 172.7±54% (P=0.001), mean CAS to 1.1±0.6 (P=0.001) and mean exophthalmometry to 19.3±2 mm (P=0.02). CONCLUSIONS: TCZ is a therapeutic option for glucocorticoid-resistant orbitopathy, and should be considered in second line due to the cost of treatment or in first line in patients with contraindications to intravenous GC pulse therapy.

RESUMO

Purpose: The aim of the present study was to analyze quantitively the lower lid contour of patients with Graves orbitopathy.Methods: Bézier curves were manually adjusted to the ciliated and nasal (or lacrimal) portions of the lower lid contour of 41 patients with Graves orbitopathy and 43 normal subjects using National Institute of Health (NIH) ImageJ software. Considering the main coordinates of the Bézier functions, the Matlab software was employed to express the lid contours with 1000 points. The first order numerical derivative of the curves was calculated in order to compare the curvature of the whole lid contour of patients and controls. The same comparison was made for the temporal and nasal contour segments. Other parameters measured included the location of the lowest point on the contours (contour peak); the position of the lateral and medial canthi, as well as the angle formed by the lower lacrimal punctum and the vertex of the inner canthus.Results: The curvature of the temporal portion of the lid contours of patients and controls correlated with both the height of the lateral canthus and the magnitude of the MRD2. Graves retraction affects the medial and lateral portion of the lid. Both segments were more curved in patients than in controls. The lower punctum was significantly lowered, increasing the angle between the lower punctum and the medial canthus.Conclusions: The increased lateral curvature of the lower lid seen in patients with Graves disease is a natural geometric effect of the increment of MRD2. The nasal portion of the lid is also significantly lowered by retraction.

RESUMO

Background: Quality of life (QoL) studies in patients with mild to moderate Graves' orbitopathy (GO) are scarce. Methods: The original GO-QoL questionnaire was translated to Portuguese and administered to 323 patients with Graves' disease. The clinically active score (CAS) was used to evaluate GO activity, and the NO SPECS and EUGOGO classifications were used to estimate GO severity. Results: The internal consistency of the GO-QoL, evaluated using Cronbach's alpha, was optimal. In people with Graves' disease and long-duration GO, both visual function and appearance scores were negatively associated with the CAS and NOSPECS and EUGOGO classifications (P < 0.001). Asymmetry and proptosis were significantly associated with the visual function and appearance domains, and diplopia was related to the visual function score. In addition, multivariate regression stepwise analysis revealed that disease severity, according to the EUGOGO classification, was associated with the visual function and appearance scores; asymmetry, presence of proptosis, and young age were associated with the appearance score (P < 0.001). The visual function and appearance scores were negatively correlated with the CAS and NOSPECS and EUGOGO classifications (P < 0.001). Conclusion: Graves' orbitopathy has a negative impact in QoL in patients with mild to moderate disease, even after an extended period, rendering GO a chronic disease. The GO-QoL questionnaire can be helpful in identifying patients in need of attention and support.

RESUMO

RESUMEN La orbitopatía tiroidea es una enfermedad autoinmune, en la que una reacción inflamatoria genera aumento de la presión orbitaria con protrusión de su contenido. A menudo es autolimitada y sus síntomas más frecuentes son retracción palpebral, exoftalmo y diplopía. Existen casos severos con compromiso de la agudeza visual por compresión del nervio óptico. El diagnóstico es clínico, pero debe complementarse con una tomografía computarizada. Su tratamiento depende de la gravedad y actividad de la enfermedad, siendo los procedimientos quirúrgicos, como la descompresión orbitaria, de elección en exoftalmo y neuropatía óptica compresiva. El pilar de tratamiento en la orbitopatía tiroidea severa es la cirugía descompresiva. Se han descrito múltiples técnicas, pero con limitaciones. La descompresión endoscópica transnasal, es considerada actualmente el procedimiento de elección, ya que permite una buena visualización de la pared medial, con resultados comparables y menores complicaciones, respecto a métodos tradicionales. Describimos un caso de oftalmopatía tiroidea severa, con exoftalmo, diplopía y disminución de la agudeza visual, en la que se realizó una descompresión endoscópica con muy buenos resultados.

ABSTRACT Thyroid orbitopathy is an autoimmune disease in which an inflammatory reaction generates increased orbital pressure with protrusion of its contents. It is often self-limiting and its most frequent symptoms are eyelid retraction, exophthalmos and diplopia. There are severe cases with compromised visual acuity due to compression of the optic nerve. The diagnosis is clinical, but must be complemented with a computed tomography scan. Its treatment depends on the severity and activity of the disease and the surgicals procedures such as orbital decompression is the best choice in exophthalmos and compressive optic neuropathy. The treatment in severe thyroid orbitopathy is decompressive surgery. Multiple techniques have been described, but with limitations. The transnasal endoscopic decompression is currently considered the gold standard, since it allows a good visualization of the medial wall with comparable results and less complications, compared to traditional methods. We present a case of severe thyroid ophthalmopathy, with exophthalmos, diplopia and decreased visual acuity, in which a transnasal endoscopic decompression was performed with very good outcomes.

RESUMO

ABSTRACT Objective Thyrotoxicosis is established risk factor for osteoporosis due to increased bone turnover. Glucocorticoids often administered for Graves' orbitopathy (GO) have additional negative effect on bone mineral density (BMD). Our aim was to examine the influence of thyroid hormones, TSH, TSH-receptor antibodies (TRAb) and glucocorticoid treatment on bone in women with Graves' thyrotoxicosis and Graves' orbitopathy (GO). Subjects and methods Forty seven women with Graves' disease, mean age 55.6 ± 12.8 (23 women with thyrotoxicosis and 24 hyperthyroid with concomitant GO and glucocorticoid therapy) and 40 age-matched healthy female controls were enrolled in the study. We analyzed clinical features, TSH, FT4, FT3, TRAb, TPO antibodies. BMD of lumbar spine and hip was measured by DEXA and 10-year fracture risk was calculated with FRAX tool. Results The study showed significantly lower spine and femoral BMD (g/cm2) in patients with and without GO compared to controls, as well as significantly higher fracture risk. Comparison between hyperthyroid patients without and with orbitopathy found out significantly lower spine BMD in the first group (p = 0.0049). Negative correlations between FT3 and femoral neck BMD (p = 0.0001), between FT4 and BMD (p = 0.049) and positive between TSH and BMD (p = 0.0001), TRAb and BMD (p = 0.026) were observed. Fracture risk for major fractures and TRAb were negatively associated (p = 0.05). We found negative correlation of BMD to duration of thyrotoxicosis and cumulative steroid dose. Conclusions Our results confirm the negative effect of hyperthyroid status on BMD. TRAb, often in high titers in patients with GO, may have protective role for the bone, but further research is needed.

RESUMO

BACKGROUND: The study was designed to compare the outcome of full-thickness blepharotomy and transconjunctival eyelid lengthening in the correction of upper eyelid retraction (UER) in patients with Graves' orbitopathy (GO). METHODS: This is a prospective randomized interventional study. Following ophthalmic examination, determination of the ocular surface disease index (OSDI) and photography, 27 patients with UER were randomly assigned to either graded full-thickness blepharotomy (G1) or transconjunctival Müller muscle recession and graded disinsertion of the levator palpebrae superioris muscle (G2). Six months later, patients were reevaluated. Digital images were analyzed with the assistance of customized software. A standardized "normal range" of upper eyelid height and contour was calculated based on healthy controls. The outcome of the two groups was compared. RESULTS: Forty-seven eyelids of 27 patients (19 female) with UER were included. Twenty-seven eyelids (15 patients) were allocated to G1 and 20 eyelids (12 patients) to G2. On average, surgery lasted 37.46 ± 5.73 min in G1 and 32.70 ± 8.39 min in G2. Based on the margin reflex distance, 93% of the eyelids in G1 and 85% in G2 were within the normal range after surgery. The corresponding figures for lid contour were 63 and 55%. Both groups displayed significant improvement in OSDI scores. No significant difference was observed in the overall comparison. CONCLUSIONS: The two surgical techniques were equally effective in the treatment of UER from GO. Postoperative contour outcomes were considerably worse in patients with severe UER than in patients with mild or moderate UER, regardless of group.

RESUMO

ABSTRACT Objective The aim of this study was to measure quality of life (QOL) impairment in individuals currently suffering from Graves' ophthalmopathy (GO) and to determine the correlation of GO-specific QOL scores with disease severity and activity. Subjects and methods Seventy three GO-specific QOL surveys were prospectively analysed and compared with GO status. The GO-specific QOL survey was translated into Spanish and applied to Argentine patients with Graves' disease (GD). Results were compared with presence or absence of GO, Clinical Activity Score (CAS), severity score, age, gender and thyroid function. Results Fifty-six patients answered the survey and underwent complete ophthalmic evaluation, 15 did not have GO and were considered to be a control group. Appearance QOL score for patients with GO (53 ± 31.4) was lower than the control group (88.3 ± 17) (p < 0,000), no difference was observed in functional QOL score. There was a negative correlation between GO severity and both functional (r = -0.575; p < 0.000) and appearance QOL (r = -0.577; p < 0.000). Functional QOL differed between patients with active GO vs control group (p = 0.043). Patients with active and inactive GO had lower appearance QOL scores than control group (p < 0.000, p < 0.001 respectively). Conclusions GO has significant impact on the life of these Argentine patients. QOL was worse in GO patients than in control group, functional QOL was mostly affected by the activity and appearance QOL was mainly altered by the effects of the disease. Patients with more severe GO had lower scores on both QOL scales.

RESUMO

Objetivo: evaluar los resultados terapéuticos obtenidos con la inyección de toxina botulínica en el músculo recto superior en pacientes con retracción palpebral moderada y grave en el curso de la orbitopatía tiroidea; determinar la influencia de algunos factores relacionados con estos e identificar las complicaciones y las reacciones adversas asociadas a su uso terapéutico. Métodos: se realizó un estudio descriptivo prospectivo en el Servicio de Oftalmología del Hospital Hermanos Ameijeiras en una serie de 21 casos con retracción palpebral moderada y grave en el curso de la orbitopatía tiroidea. La inyección de toxina botulínica en el músculo recto superior para la corrección de la retracción de la orbitopatía tiroidea se realiza por primera vez en el país. Resultados: fueron satisfactorios en el 66,7 por ciento de los casos. La edad y la gravedad clínica de la retracción fueron los factores que influyeron sobre la respuesta terapéutica (p= 0,013 y p= 0,015 respectivamente). Conclusiones: la inyección de toxina botulínica en el músculo recto superior es efectiva en la mayoría de los casos tratados, sobre todo en adultos jóvenes y con menor gravedad clínica de la retracción. La hipercorrección es la complicación más temida de este procedimiento(AU)

Objective: to evaluate the therapeutic results of the botulinum toxin injection in the upper rectus muscle in patients with moderate and severe eyelid retraction in the course of thyroid orbitopathy, and to determine the influence of some factors related to these patients and to identify the complications and adverse reactions associated to its therapeutic use. Methods: prospective and descriptive study was carried out at the ophthalmological service of Hermanos Ameijeiras hospital in a 21 case series study with moderate and severe eyelid retraction in the course of thyroid orbitopathy. The injection of botulinum toxin into the upper rectus muscle for the correction of retraction in thyroid orbitopathy was performed for the first time in the country. Results: in this group, 66.7 percent of patients had satisfactory results. Age and clinical severity of retraction were the factors having influence on the therapeutic response (p= 0.013 and p= 0.015 respectively). Conclusions: the botulinum toxin injection into the upper rectus muscle is effective in most of treated cases, mainly in young adults with less clinical retraction severity. Hypercorrection is the most fearful complication in this procedure(AU)
