Abstract
To evaluate the effect of Cyclosporin A in the management of Graves' ophthalmopathy, we treated 13 patients with severe euthyroid endocrine eye disease with the immunosuppressive drug. Follow up consisted of clinical investigation, laboratory evaluation with detailed thyroid function tests and complete ophthalmological assessments including A and B scan ultrasound and computerized tomography (CT) of the orbits. Cyclosporin A given over 4–7 months resulted in improvement of clinical signs and symptoms of the disease due to a positive effect of the drug on soft tissue changes. The more objective methods did not demonstrate any unequivocal change in proptosis, visual acuity, intraocular pressure and thickness of extraocular muscles. Cyclosporin A was not able to stop acute progression of ophthalmopathy in one patient and did not obviate surgical decompression of the orbits in two more patients. There was no measurable effect of treatment on the underlying immunological process with regard to thyroid disease.
