title: Abnormalities of the pupil and visual-evoked potential in quinine amblyopia.
abstract: Total blindness with a transient tonic pupillary response, denervation supersensitivity, and abnormal visual-evoked potentials developed in a 54-year-old man after the use of quinine sulfate for leg cramps. He later recovered normal visual acuity. A transient tonic pupillary response, denervation supersensitivity, and abnormal visual-evoked potentials in quinine toxicity, to our knowledge, have not been previously reported.
