• Atypical ocular bobbing resulted from an intentional poisoning from dimpylate (Diazinon), an organophosphate compound. In discussing the possible foci and mechanism for atypical ocular bobbing associated with acute organophosphate poisoning, we suggest acetylcholine as a neurotransmitter substance within the ocular motor pathway. A literature review has not shown any previous reported cases with this sign.
