title: [A new aspect of the anomalies of visual acuity in relation with the four principal directions of the test (author's transl)].
abstract: The visual acuity in the four principal directions of the test of Landolt-C is different. This difference increases in the near vision but not in a regular manner, and neither for a certain direction nor in a given period of the experiment. We have proposed a neural interpretation for this phenomenon.
