[Management of patient with Gaves' orbitopathy].

Graves' orbitopathy (GO) is the most common and important extrathyroidal manifestation of Flajani-Basedow-Graves' disease, with autoimmune etiology. In most cases they are mild forms, in 3-5% they are severe and progressive. For therapeutic purposes, it is classified according to the severity (mild, moderate-severe or sight threatening), to the activity (active if clinical activity score is >=3), and to the impact on quality of life. The choice of medical or surgical therapy depends on the activity of the disease. Therapy for mild GO consists of abolition of risk factors, local treatments, oral administration of selenium. Therapy for moderate-severe and active GO consists of administration of intravenous, oral, topic and local (retrobulbar, peribulbar and subconjunctival) glucocorticoids (GC). The therapy of choice, after careful selection of patients, is pulse therapy with intravenous GC, with 79% of response. Orbital radiotherapy is effective in 60% of cases; diabetes mellitus and hypertension are absolute contraindications. Contemporary administration of oral GC and orbital radiotherapy are more effective than single therapies. Marginal and not validated therapies are cyclosporine, somatostatin analogues, TNF-a inhibitors and rituximab. The treatment for dysthyroid optic neuropathy (DON) consists of combination of steroids, orbital radiotherapy and, if necessary, orbital decompression surgery. The surgical therapies are orbital decompression and rehabilitative surgery.
