Miller-Fisher syndrome is defined as ophthalmoplegia, ataxia and areflexia. 
Considered as a variant of Guillain-Barré syndrome, it differs in its clinical 
presentation and by anti-GQ1b antibody positivity. The authors report a case of 
Miller-Fisher syndrome characterized by ataxia and complete ophthalmoplegia. 
Through this example, the range of ophthalmologic clinical manifestations are 
discussed.
