Objective determination of accommodation in 38 children with permanent central scotoma due to amblyopia on one side (with central and eccentric fixation) revealed: 1. The physiological adaptation of refraction for far and near distances did not serve its purpose. 2. There was either no or an irregular response on hyperopia, which was produced by placing concave lenses in front of the eye while fixing a far object, or on myopia produced by placing convex lenses in front of the eye while fixing a near object. 3. On hindering clear vision which could not be compensated by accommodation there was contrary to normal eyes no reactive change of refraction at all or only a poor one. The accommodation behavior in eyes with permanent central scotoma due to amblyopia does not differ from that in eyes with permanent central scotoma due to organic lesions when using the same test methods.
