He was very clumsy in many things, often injuring himself, and he couldn't learn to read and write properly in school, even though he knew a lot otherwise. He claimed that the letters would all run away from him and that dinosaurs would eat them, and he was afraid of many things. The visual defect known as strabismus is an important factor in the gross and fine motor as well as psychological development of children. Therefore, there is significant interest in occupational therapy regarding information on the effects, influences, and correction possibilities of strabismus. This book contains, in an understandable and comprehensible form, alongside the classic work by Uwe Wulff on disturbed binocular vision and school failure, contributions for occupational therapists as well as for non-ophthalmologists and non-optometrists regarding the correction of strabismus.
