Intoxication with beta, beta' -iminodipropionitrile: a model of optic disc swelling.

Human and experimental pathologic studies have suggested that optic disc swelling is due to enlargement of axons in the optic nerve head. Beta, beta' -Iminodipropionitrile (IDPN), a toxin known to produce neurofibrillary swellings in proximal portions of motor and sensory axons, was used to induce axonal lesions in the visual system of guinea pigs and dogs… CONTINUE READING
