[Evidence for the developmental theory of myopia. 1. The role of accommodation in the development of myopia]

The causal part of weakened accommodation in the formation of myopia is linked with the visual activity at near-distance. Feeble accommodation can be caused by a morphological deficiency of the ciliary muscle and its insufficient training, also by a reduced blood-supply of the eye and by the influence of general diseases on the ciliary muscle. For the first time the thought is expressed to prevent myopia and its progression by influencing the accommodative apparatus of the eye.
