Visual optics in toads (Bufo americanus)

  title={Visual optics in toads (Bufo americanus)},
  author={Ute Mathis and Frank Schaeffel and Howard C. Howland},
  journal={Journal of Comparative Physiology A},
Aspects of visual optics were investigated in the American toad (Bufo americanus). The development of the refractive state of the eye during metamorphosis was followed with IR photoretinoscopy. Frozen sections documented the changes in optical parameters before and after metamorphosis. There is a difference in light sensitivity between juvenile and adult toads. Binocular accommodation in adult toads was observed. 1. IR photoretinoscopic measurements showed that the refractive state of the eye… CONTINUE READING
