Incomplete Third Nerve Palsy Due to a Carotid-Cavernous Fistula.

Introduction: The approach to oculomotor nerve palsies involves the exclusion of compressive, infective, inflammatory, or ischemic lesions. Dural arteriovenous fistulae, including carotid-cavernous fistulae (CCF), are known causes of third nerve palsy. However, diagnosis can sometimes be delayed or missed due to the various clinical presentations.

Starvation-induced diplopia and weakness: a case of beriberi and Wernicke's encephalopathy.

A 56-year-old teetotaller man with hypertension and gout presented with a week duration of painless worsening diplopia on a background of loss of weight and appetite, generalised lethargy and weakness for 1 year. On examination, he was noted to be hypothermic and tachycardic with generalised muscle wasting. Proximal myopathy, lower limb fasciculations and areflexia, restricted bilateral eye abduction and nystagmus were observed.
