EELLS, J.T et al. Deficiencia de folato y concentraciones elevadas de formato en suero y líquido cefalorraquídeo de pacientes con neuropatía óptica epidémica*. Rev Cubana Med Trop [online]. 2000, vol.52, n.1, pp. 21-23. ISSN 1561-3054.

We studied 62 patients aged 48 years as an average and diagnosed with bilateral optical neuropathy during an epidemics in Pinar del Río province. Of these patients, 42 showed the optical form whereas 20 had the mixed form of optical neuropathy. We researched into the levels of formate and folate in serum and cerebrospinal fluid samples and we found a marked deficiency of folates in more than 50 % of samples and high formate concentration levels in almost 25 % of samples. We concluded that nutritional shortages that lead to a reduction of folates, and the intake of small amounts of methanol in alcoholic drinks could lead to lacking energetic states which would facilitate that the optical nerve be affected and the epidemic optical neuropathy appear.
