Exophthalmos occurs in more than half of the patients with childhood Graves' disease, while severe Graves' ophthalmopathy is uncommon in children. Myasthenia gravis is even more rare in association with Graves' disease. A 7-year-old girl is reported; she had ptosis for two years; this was treated irregularly, and she then developed exophthalmos, ophthalmoplegia and thyroid goiter. Her laboratory tests showed T3 496 ng/dl, T4 17.05 ug/dl, TSH < 0.1 uU/ml, fT4 > 4.2 ng/dl. Antithyroglobulin antibody was 1:25600 and antimicrosomal antibody was 1:102400. Myasthenia gravis was confirmed by a positive neostigmine test. Due to allergic reaction to propylthiouracil, she was treated with carbimazole and propranolol. Thereafter the thyrotoxicosis was was well controlled. The ocular-type myasthenia gravis remained stable with minimum medical treatment.

A 44 year old diabetic woman presented with diplopia and bilateral ptosis and mild exophthalmos. The patient was clinically euthyroid, the baseline thyroid function tests were normal, but the thyroid stimulating hormone response to thyrotrophin releasing hormone was flat. Computed tomographic scan and magnetic resonance imaging of the orbits showed left medial and inferior rectus muscle thickening, more prominent on the left side, consistent with Graves' disease. The tensilon stimulation test resulted in resolution of the ptosis and partial improvement of the ophthalmoplegia. The single fibre electromyography was consistent with a defect in neuromuscular transmission. However, forced duction test was normal and anti-acetylcholine receptor antibodies were undetectable. Significant improvement of the extraocular muscle function and resolution of the right ptosis had resulted from anticholinesterase therapy. These findings and the clinical response to therapy were consistent with concomitant euthyroid Graves' ophthalmopathy and ocular myasthenia gravis. Coexistent isolated ocular myasthenia gravis and Graves' ophthalmopathy is rare and should be considered in patients with findings of ocular myasthenia and extraocular muscle dysfunction.

Graves' ophthalmopathy occurs in 2% to 7% of patients with Graves' disease with the major manifestations being proptosis, ophthalmoplegia, optic neuropathy and/or eyelid retraction. Although autoimmune in nature, the precise pathophysiology is unknown. The course of the ophthalmopathy is not influenced by the mode of treatment of the hyperthyroidism. In addition to restoration of the euthyroid state, the aims of treatment include relief of eye pain, correction of extraocular muscle dysfunction, protection of visual acuity and improvement of appearance. Specific therapy depends on the severity of the ophthalmopathy and varies from lubricating eye drops in mild disease to high-dose steroids and radiotherapy or decompressive surgery in severe cases.

The authors report one case of Graves' ophthalmopathy with a palpebral asymmetry, which was characterized by a left ptosis and a right palpebral retraction. In connection with Graves' disease, many ocular signs were described, including exophthalmos, ophthalmoplegia, palpebral retraction and visual loss, but unilateral ptosis was rarely reported. The orbital CT-scanning demonstrated the bilateral enlargement of the extraocular muscles, due to the infiltrative process met in Graves' disease. The ptosis and the palpebral retraction were suspected to be related to the extension of this infiltrative process in the levator palpebrae.

A retrospective analysis of 29 patients with Graves' ophthalmopathy treated from 1973-1986 was undertaken to evaluate the use of radiation therapy (RT). Most patients presented with advanced disease; 20 had been treated with steroids and 8 had undergone prior surgery with orbital decompression. Post-RT evaluation was performed by the patients' Radiation Oncologist, Ophthalmologist, and Endocrinologist with a median follow-up period of 45 months. The overall assessment of the patients' disease was judged as improved with respect to the majority of signs and symptoms in 48%. Soft tissue changes were relieved in 78% and proptosis reduced in 52%. Ophthalmoplegia responded poorly and was improved in only 24%. After RT, 26/29 (90%) of patients have had no further steroid requirements. Thirteen patients underwent surgery for residual signs/symptoms post radiation therapy, indicating that combined modality may be necessary in many patients with advanced disease.

A treatment technique employing retrobulbar supervoltage radiotherapy (XRT) in Graves' ophthalmopathy is described. Twenty-eight patients have been treated and followed between 1980-1983. Twenty-six of 28 patients (93%) showed some response, with 19/28 (68%) having a good to excellent response. Four of 28 (14%) had recurrent symptoms post-XRT. Soft tissue signs and symptoms were relieved and disease progression arrested in the majority of patients, but proptosis and ophthalmoplegia responded poorly. High dose corticosteroids have generally been the alternative form of therapy for this disease. Post-XRT, 24/28 (86%) of patients have had no further steroid requirements, and been spared the associated complications. Treatment was well tolerated, with only five patients (18%) demonstrating a transient worsening of symptoms which settled entirely within 2 weeks. No long-term complications have been encountered. Eleven patients had post-XRT CT scans which were compared to pre-treatment scans and clinical response. Nine of 11 patients (82%) had CT changes in general agreement with the observed clinical response, but the degree of involvement seen on the initial CT scan was not predictive of response nor the risk of relapse. XRT with the described technique is felt to be an effective, safe, and practical approach to the disabling and disfiguring complications of severe Graves' ophthalmopathy.

A case of Graves' ophthalmopathy, ocular myasthenia gravis (MG) and Hashimoto's thyroiditis is presented, an association that has not been previously reported. A 22-year-old woman presented with exophthalmos and a normal-sized thyroid. Four years later, shortly after delivery of her second child, ocular MG developed. Twenty years after her initial symptoms, Hashimoto's thyroiditis and mild hypothyroidism were diagnosed. Treatment of the latter brought about marked improvement of the ophthalmoplegia. The differential diagnosis of ophthalmoplegia is discussed, and the importance of recognizing and treating hypothyroidism in MG is emphasized. Since Hashimoto's thyroiditis as well as MG have an abnormality of T-lymphocyte regulatory function, and the autoimmune process is directed in both diseases against cell membrane receptors, they can be considered as pathogenetically related. The reported case exemplifies this association.

The effects of different methods of treatment of Graves' ophthalmopathy were evaluated in a series of 48 patients. Thirty-six patients were given combined treatment with orbital cobalt irradiation and systemic 6 alpha-methylprednisolone (methylprednisolone). Included in this group were 12 of 24 consecutive patients who were randomly assigned to either combined therapy or systemic methylprednisolone alone. The degree of ocular involvement and responses to treatment were evaluated by numerical scoring (ophthalmopathy index) and clinical assessment. Of the 36 patients treated by combined therapy, 12 (33%) showed excellent responses, 14 (39%) showed good responses, 9 (25%) showed slight responses, and 1 (3%) had no response. Treatment was more effective for soft tissue involvement, newly developed ophthalmoplegia, and optic neuropathy, while proptosis and longstanding ophthalmoplegia were less responsive. There was an inverse relationship between the duration of ophthalmopathy and the efficacy of treatment, more favorable results being observed when symptoms had been present for less than 2 yr. Treatment with systemic methylprednisolone alone was also effective, but, in general, responses were less satisfactory; 4 of the 12 patients of this group (33%) had good responses, 6 (50%) had slight responses, and 2 (17%) had no response. The results obtained in the 24 patients randomly assigned to combined therapy or steroid treatment alone were compared by evaluating changes in the ophthalmopathy index. Mean initial ophthalmopathy indices (6.4 vs. 6.2, respectively) showed no significant differences between the 2 groups, whereas the mean decrease in the group receiving combined therapy (4.8) was significantly greater (P less than 0.05) than that in the other group (3.2). In conclusion, the present study indicates that both orbital cobalt irradiation combined with systemic methylprednisolone treatment and systemic methylprednisolone therapy alone are valuable methods of treatment for Graves' ophthalmopathy, but the combined therapy proved to be more effective.

Thirty-four patients with childhood Graves' disease were examined to determine the incidence and severity of Graves' ophthalmopathy in children and adolescents. Twenty-three of the 34 patients formed a population of childhood Graves' disease unselected for ocular disease; 11 were unaffected and 12 (52.2%) had findings considered to be of mild functional importance. The remaining 11 patients were referred for evaluation because of a history of Graves' ophthalmopathy; eight (72.7%) exhibited findings of mild severity and three the more meaningful complications of ophthalmoplegia. There were no cases of dysthyroid optic neuropathy or sight-threatening corneal involvement. Both the presence of asymmetric ocular manifestations and increasing severity of disease seem to correlate with increasing age. Although ophthalmoplegia does occur infrequently, Graves' ophthalmopathy in children and adolescents seems to be a substantially more benign process than that seen in adults.

Malignant exophthalmos or the ophthalmic component of Graves' disease is a functionally impairing and cosmetically deforming disorder of orbital tissue, separate from the sympathetic effects of thyrotoxicosis. The deposition of immune complexes of thyroglobulin and its antibodies within orbital muscles results in progressive exophthalmos, ophthalmoplegia, chemosis, and lid fullness. Increasing intraorbital edema and optic nerve tension may produce irreversible retinal ischemia. If unresponsive to medical treatment, patients exhibiting increasing loss of visual acuity are therefore candidates for emergency surgery. Early attempts at surgical correction of the mechanical aspect of Graves' ophthalmopathy were unsuccessful. The current technique of transantral orbital decompression, when done before extreme advancement of the ocular disease, is successful and meets the following objectives: It restores visual loss and prevents further deterioration of visual acuity, protects the cornea, restores extraocular muscle movements, decreases intraorbital pressure, produces a satisfactory cosmetic result, and avoids serious complications. Patients with persistent extraocular muscle imbalance or lid lag may ultimately require oculoplastic surgery.
