Low Vision in Children
This slide collection covers most of my slides on the specific features in thedevelopment of preschool visually impaired children, mostly children with moderateor severe low vision. The texts next to the thumbnail pictures are rather short.If you want to read more, references to my articles and booksare at the end of the text. I have received some of the slides from the teachingcollections of my colleagues and coworkers. The legends of these slides mention thesources. About one half of the slides have been photographed by parents or therapistsof my little patients, often specifically requested for my lectures. I would liketo express my heart felt thanks to everyone who has helped in building this teachingmaterial.
Level of wakefulness
Spatial concepts I
Spatial concepts II
Spatial concepts III
Visual impairment affects all areas of development. The most important areas are communication, bonding, level of wakefulness, motor development, spatial concepts, balance, object permanence, picture perception, incident learning, language development and social interaction. The three last mentioned areas of development belong to special education rather than ophthalmology and are therefore not included in this slide collection.
In the area of motor development the effect is most noticeable in oculomotor functions, head control, hand regard, bringing hands to midline, reaching and in starting to move.
Visually impaired infants and children need to use compensating techniques. Some visually impaired children develop mannerisms.
