YANES QUESADA, Marelis et al. Frequency and clinical characteristics of thyroid-associated orbitopathy in recently diagnosed hyperthyroid patients. Rev Cubana Endocrinol [online]. 2013, vol.24, n.3, pp. 258-269. ISSN 1561-2953.

Introduction: thyroid-associated orbitopathy is a frequent complication of hyperthyroidism. Objective: to describe the frequency and the characteristics of orbitopathy related to autoimmune disease of thyroids in patients who were recently diagnosed as hyperthyroidism cases. Methods: cross-sectional descriptive study. Every case was detected thyroid hormones and antiperoxidase antibodies at time of diagnosis. They were examined to evaluate the possible presence of orbitopathy whose ocular symptoms and signs were identified in those who had it. The comparison of results was made through summary statistics by using chi-square test. The statistical significance was p< 0.05. Results: seventy percent of patients had thyroid orbitopathy at the time of diagnosis. Females and Caucasians prevailed in the study group. The slight inactive form prevailed whereas the severe form was absent. The most common sign was palpebral retraction accounting for 90.32 %. There was no statistical association with age, smoking, race, thyroid hormone or antibody presence. Conclusions: orbitopathy is common at time of diagnosis of hyperthyroidism, palpebral retraction is the commonest sign and it was not associated to the studied clinical and biochemical factors.
