Graves' orbitopathy (GO) is the main extrathyroidal manifestation of disease (GD). Choice treatment should be based on assessment clinical activity and severity GO. Early referral to specialized centers fundamental for most patients with Risk factors include smoking, thyroid dysfunction, high serum level thyrotropin receptor antibodies, radioactive iodine (RAI) treatment, hypercholesterolemia. In mild active GO, control risk factors, local treatments, selenium (selenium-deficient areas) are...

Background: At the onset of thyroid-associated orbitopathy (TAO), most patients are hyperthyroid, while scarce data available on euthyroid/hypothyroid TAO. The aim this study was to assess prevalence, phenotype, and psychosocial burden with initially Methods: medical records 461 consecutive unselected TAO followed at a specialized joint thyroid–eye clinic were analyzed within retrospective cross-sectional study. Main outcome measures prevalence eu- or hypothyroid as well ophthalmic signs...

In patients with thyroid-associated orbitopathy (TAO), the dry eye syndrome occurs frequently, and symptoms signs of both disorders overlap making early accurate differential diagnosis difficult. A differentiation via specific markers is warranted.Tear fluid samples 120 subjects TAO, TAO + eye, controls were collected. The measured using matrix-assisted laser desorption ionization mass spectrometry. identified proteins tested antibody microarrays.Proteomics deregulated in eye. Compared...

Background Graves’ orbitopathy (GO) is subject to epidemiological and care-related changes. Aim of the survey was identify trends in presentation GO European Group On Orbitopathy (EUGOGO) tertiary referral centres initial management over time. Methods Prospective observational multicentre study. All new referrals with diagnosis within September–December 2019 were included. Clinical demographic characteristics, timelines therapeutic decisions recorded. Data compared a similar EUGOGO performed...

Although several risk factors for retinal vein occlusion (RVO) are known, what triggers RVO is unclear in many cases. We aimed to evaluate the relevance of multiple patients with RVO. The Gutenberg Study an observational case-control study that assessed thrombophilic, cardiovascular, ophthalmic, and drug-related participants same number matched controls. Conditional logistic regression analysis was chosen estimate due factors. Of 92 RVO, 46 (50%) had central 31 (33.7%) branch 15 (16.3)...

Common autoimmune disorders tend to co-exist in the same subjects and cluster families. The objective of this study was determine prevalence co-morbidity patients with thyroid disease (AITD) without thyroid-associated orbitopathy (TAO). This a cross-sectional conducted at an academic tertiary referral centre. Of 1310 AITD [n = 777 or 59% Graves' (GD) n 533, 41% Hashimoto's thyroiditis (HT)] followed specialized joint thyroid-eye out-patient clinic, 176 (13·4%) had adult type polyglandular...
