Optic Neuropathy: Cassava Poisoning?

Abstract

When a middle-aged male patient presented with painless vision loss, a pale optic disc, and predominantly papillomacular bundle damage in both eyes for unknown reasons, Leber’s hereditary optic neuropathy and other diseases that may cause optic atrophy in both eyes should be ruled out at first, and furthermore, the history of toxin and drug exposure should be taken into consideration to exclude the possibility of toxic optic neuropathy.
