The quality of life of patients with Graves’ orbitopathy (GO) may be seriously damaged due to the changes in appearance, working abilities and everyday activities. The reasons for the deterioration in quality of life in GO are proptosis, diplopiae and/or eyesight obstructions, as well as inflammatory changes in the soft tissues of the eye and eyelids. That is why the European Group for Graves’ orbitopathy (EUGOGO) have developed a special questionnaire with the aim to establish a standardised evaluation of how GO affects quality of life. It consists of two subscales with 8 questions each, which are all relevant in terms of everyday activities and psychosocial adjustment. The questionnaire is part of the criteria for the evaluation of the GO therapy response.
