This book offers ophthalmologists and medical practitioners a concise, data-driven review of the information that is most relevant in guiding the diagnosis and management of thyroid-associated eye diseases (TED). Thyroid-Associated Eye Disease can be read in its entirety to give a perspective of the field, but also considered as a reference as clinical questions arise.   The goal is to deliver data- driven guidance and discreet approaches and suggestions useful for clinical practice and decision making. Advances in diagnostic evaluation, including autoantibody assessment, are reviewed, and the diagnostic features of euthyroid TED are also discussed. All relevant aspects of treatment are covered, from the use of radioactive iodine, long-term medical therapy, and surgical thyroidectomy through to the treatment of active TED by steroids and novel biologics and the role of minimally invasive surgery. Numerous supporting images are included, and helpful checklists will aid the practitioner in treatment decision making.
