title: Isolated ptosis as acute ophthalmoplegia without ataxia, positive for anti-GQ1b immunoglobulin G.
abstract: Anti-GQ1b IgG antibody syndrome comprises a wide range of diseases presenting with ophthalmoplegia and ataxia. Anti-GQ1b antibodies have been strongly associated in the literature with Miller Fisher Syndrome, with acute ophthalmoplegia associated with Guillain-Barré syndrome, and with isolated ophthalmoplegia. Acute ophthalmoplegia presents as various combinations of external and internal ophthalmoplegia. Reported here is a novel case of isolated ptosis as a manifestation of ophthalmoplegia. The present finding of bilateral ptosis and areflexia with anti-GQ1b IgG antibody positivity helps confirm the existence of the syndrome. Further research is needed on diagnosis and treatment.
