Introduction: The link between nutritional status and either optic or peripheral neuropathies is well established with tobacco, ethanol, deficiencies in thiamine, vitamin A, B12, B3 and B6 and protein-energy malnutrition all being causative.
Case presentation: We describe the case of a 32-year-old Afro-Caribbean of Jamaican origin presenting with blurred vision and a painful burning sensation in his feet. The clinical features were consistent with optic and peripheral neuropathy.
Conclusions: The patient followed a strict vegan diet and consumed no animal products. A review of the literature highlights similarities between this case and Strachan's syndrome, a combination of optic and peripheral neuropathy and cutaneous excoriation, providing further evidence for the association between this clinical presentation, dietary deficiency and, as recently postulated, previous residence in a tropical or sub-tropical climate.
