The indications for orbital decompression are determined in the course of thorough eye examination. An important objective of examination of a patient with thyroid eye disease (TED) is determination of inflammation activity and severity. Orbital decompression is a surgical procedure that can be performed in both the active and non-active stages of the disease. However, the indications for the surgery in these cases are different. Optic neuropathy and severe corneal disease are threatening complications that may lead to permanent visual loss and generally occur in the presence of active orbital inflammation. If treatment with high-dose corticosteroids has proven ineffective, an urgent surgical procedure consisting of orbital decompression and, in case of involvement of the cornea, eyelid and corneal surgery has to be performed. Owing to significant progress in technology, improvement of methods and accumulated experience over the past decade, the indications for bone orbital decompression have extended compared to the time when this procedure was used only in patients with extremely severe TED. The most common complication of the orbital decompression is the development or deterioration of previously existing binocular diplopia and strabismus. In addition, other parameters may change as well, including the position of the globe, the eyelids, the angle of deviation of the eye, and intraocular pressure. Thus, bone orbital decompression is a major step of a comprehensive, often multistage, system of rehabilitation of patients with severe refractory TED.
