This booklet was inspired by the need of educators and therapists of preschool students who are blind and visually impaired to share their observations of children with Optic Nerve Hypoplasia (ONH) and the therapies found to be helpful when working with these children. The work done at the Blind Childrens Center is very rewarding, and these educators and therapists never imagined that one day they would take on such a challenging, yet rewarding endeavor. Chances are that if one is reading this booklet it is because they have a child with ONH or are working with a child with this condition. Whatever the reason, these authors hope readers find the information included both helpful and educational. The intention was to make this booklet user friendly and easy to read. When the authors started thinking about writing about their experiences with children who have this diagnosis they were not sure if there would be an audience for it. As they searched for literature on the subject, they found that very little has been written on the educational implications that ONH presents. What has been written is filled with medical terminology which makes it sometimes difficult to read and understand. The aim of this booklet is to be as straight-forward and as easy to understand as possible. To be accurate, however, when discussing such a complex diagnosis the authors did need to use terminology that requires clarification. At the end of the booklet, they have included appendixes that have definitions, Web sites and organizations that may be helpful. Following the introduction (Rosalinda Mendiola), the table of contents presents the following four chapters: (1) Vision Issues: A Multidisciplinary Approach (Rosalinda Mendiola); (2) Strategies for the Classroom Teacher: Working with Preschool Children with ONH (Cheryl Bahar); (3) Occupational Therapy: For Children with Optic Nerve Hypoplasia and Associated Developmental Concerns (Jill Brody); and (4) Speech and Language Development: In Children with ONH (Gayle L. Slott). Appended are: (1) Terms Commonly Used in Relation to ONH; and (2) Web sites of Interest. A list of references is also included.
