PURPOSE: To clarify in which cases of blow-out fractures ocular motility will naturally recover. DESIGN: A retrospective review of observational cases. METHODS: Involved ocular motility ranges were measured by the Hess screen test at 15 or 30 degrees in 23 nonsurgical blow-out fracture patients without muscle entrapment or strong mechanical ocular restriction and in eight surgical patients with the above. RESULTS: In nonsurgical patients, the eyes moved more than 10 or 20 degrees respectively on a 15- or 30-degree Hess screen test in the early period, whereas in the surgical patients, the eyes did not. No nonsurgical patients had serious ocular motility disturbances; however, natural ocular motility recovery in many patients took more than 4 weeks. CONCLUSIONS: When an involved eye without muscle entrapment or strong mechanical restrictions moves more than 10 or 20 degrees on each Hess chart, natural recovery can be expected.
The complications of dysthyroid ophthalmopathy should be known and screened in every patient since they can worsen visual prognosis and are critical to the decision for treatment. Ocular surface alteration can result from eyelid malposition, blinking deficiency, eye dryness, and proptosis. Oculomotor disorders are detected by coordimetry or a forced duction test. Optic neuropathy can be compressive or glaucomatous. Intraocular pressure elevation can result from elevation of intraorbital pressure, indentation by an enlarged muscle, or increased backflow in episcleral veins.
Graves' ophthalmopathy (GO) is the most frequent extrathyroidal manifestation of Graves' disease, an autoimmune disorder of the thyroid, whereas the precise pathogenesis still remains unclear. In Hashimoto's thyroiditis the occurrence of proptosis is an extremely rare event. The therapy for middle and severe courses of GO shows in partly disappointing results, although several therapy modalities are possible (glucocorticoid therapy, radiotherapy, antithyroid drug treatment, surgery). All these therapies lead in only 40 - 70 % to an improvement of the pathogenic symptoms. An intensive interdisciplinary cooperation is necessary to satisfy the requirements for the treatment of Graves' ophthalmopathy. As a consequence of the very different results of the few of clinical studies that were accomplished with reference to this topic, treatment by radiotherapy in the management of the disease is presently controversially discussed. In the German-speaking countries the radiotherapy is, however, firmly established as a therapy option in the treatment of the moderate disease classes (class 2-5 according to NO SPECS), especially if diplopia is present. This article describes the sequences, dosages and fractionation schemes as well as the risks and side effects of the radiotherapy. Altogether, radiotherapy is assessed as an effective and sure method. The administration of glucocorticoids can take place before the beginning of or during the radiotherapy. For the success of treatment the correct selection of patients who may possibly profit from a radiotherapy is absolutely essential. By realising that GO proceeds normally over a period of 2-5 years, which is followed by a period of fibrotic alteration, the application of the radiotherapy in the early, active phase is indispensable. A precise explanation for the effects of radiotherapy in treatment of the GO does not exist at present. The determination of the most effective irradiation doses was made from retrospectively evaluated collectives. Recently the results of a national survey of all German RT departments were published, initiated by the working group of the DEGRO (German Society of Radiooncology). In the most of the German radiooncology departments irradiation with 8 to 10 x 1.8-2.0 Gy 5 x weekly to 16 or 20 Gy is standard. Two recently published prospective German studies pointed out the equivalence of the effectiveness of a short therapy in low dose ranges up to 2.4 Gy as well as of a low proportioned irradiation during a longer period in relation to a standard therapy with 20 Gy. That is why at the moment it is not possible to give a definite recommendation with reference to dosages or the fractionation schemes. In 2003 the first European group (European Group on Graves ' Orbitopathy Experience -- EUGOGO) was founded for pursuing investigations of GO in multi-centric studies, mainly to improve therapy results.
