Computer analysis of orbital fat and muscle volumes in Graves ophthalmopathy.
A technique using special computer programs and data from high-resolution computed tomographic scans has been developed that provides accurate and reproducible volume measurements for muscle and fat in the orbit. Normal values for retrobulbar fat and muscle were established in 19 adults. Nineteen patients with Graves exophthalmopathy were then studied, and a spectrum of change was found that in...
متن کاملThyroid-associated Ophthalmopathy
Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves' disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. Th...

متن کاملThiazolidinedione precipitated thyroid associated ophthalmopathy.
Thyroid associated ophthalmopathy (TAO), a cardinal clinical pointer to diagnose Graves' disease (GD), is seen less frequently in our country than in the West, but can have sight threatening consequences. Smoking, diabetes, male gender, increasing age and radioactive iodine treatment for thyrotoxicosis are known precipitating factors for TAO. We report four cases of thiazolidinediones (TZD) pre...
متن کاملSpontaneous bony orbital auto-decompression in thyroid ophthalmopathy.
Orbital 'auto-decompression' in TED (thyroid eye disease) is a well recognised phenomenon in older patients where lax orbital septa allow proptosis to decompress the orbit. Bony 'auto-decompression' in TED is a different entity which to the best of our knowledge has not been previously reported. We describe such a case which presented spontaneously, in the absence of trauma or bony pathology, a...
