  • Abstract
  • Look Inside

Four subjects, who were congenitally blind or who lost sight in early infancy, were followed up in order to investigate the acquisition process of visual functions following surgery to recov-er vision. The investigations included learning process in discriminating color, two-dimensional shape, solid form and perspective drawings.

Subject M.M. lost sight due to keratomalacia 10 months after birth. After successful optic iridectomy, we started to have her learn to discriminate between two colored patches since she could not see any color immediately after the operation.
