When young children experience subnormal vision, an array of evaluation tools and techniques is used to assess visual function. Some children who have retinopathy of prematurity may require surgery. Post-operatively, at the Children's Low Vision Center in Boston, the pediatric ophthalmologist evaluates the child's visual functioning using a variety of devices. A tool called the Visual Hand Display has been introduced to enhance the physician's methods of evaluation, thereby achieving greater understanding of the child's visual responses. Collaborations among the doctors, educators, therapists, and patients are emphasized.
