Abstract: Miller Fisher syndrome (MFS) is a triad of total external ophthalmoplegia, ataxia, and areflexia, while botulism has the usual clinical presentation of involvement of cranial muscles and palsies with blurred vision, diplopia, ptosis, dilated pupils, and facial paralysis, caused by a bacterial neurotoxin which attacks proteins involved in presynaptic vesicle release. In this report, we needed to make the differential diagnosis between MFS and botulism in a patient who presented with acute ophthalmoparesis and a history of diarrhea three days before, which started two days after consuming tinned food. Routine laboratory, neurophysiologic, and imaging investigations were normal. A clinical diagnosis of Miller Fisher syndrome was reached by anti-ganglioside GQ1B and GM1 Ig G and M antibody investigations which proved positive. The patient was treated with intravenous immunoglobulin two weeks after (in the late period) the symptoms started and he has recovered completely. Systemic autoimmune diseases should be considered in patients with bilateral ophthalmoparesis. As in the present patient, the evaluation of specific antibodies helps in the diagnosis and thus early effective treatment is possible.
