Graves' disease presenting with bilateral acute painful proptosis, ptosis, ophthalmoplegia, and visual loss.
Two middle-aged women presented with bilateral acute painful proptosis, ptosis, ophthalmoplegia, and visual loss. In both an initial diagnosis of orbital cellulitis was made, but they did not respond to systemic antibiotics. Orbital computerised tomographic (CT) scans were thus done within 36 h of admission and they showed grossly enlarged extraocular muscles in each case suggestive of dysthyroid eye disease. Clinical examination was otherwise normal. When high doses of systemic steroids were substituted for the antibiotics the physical signs resolved rapidly, accompanied by a dramatic reduction in the size of extraocular muscles on CT scanning. One patient subsequently became clinically hypothyroid, while the other showed clinical and biochemical evidence of thyroid overactivity. These case-reports suggest that patients with bilateral acute painful proptosis should have an early CT scan to exclude atypical dysthyroid disease. Delay in giving systemic steroids may allow the development of unnecessary visual loss due to optic nerve damage.
