Depending on the size and placement of the crescent, an eye care professional or a trained technician can determine if there is a possible refractive error or an alignment problem. A group of pediatric ophthalmologists donate their time to analyze those photos that indicate possible vision problems. The postcard states that the child shows symptoms of amblyopia and recommends that the child receive a complete eye exam with an eye care professional of their choice. Questionnaires are mailed to the parents' two months after the postcard is sent, to ask if the child received a professional eye exam and what the results of the exam were. Photo shows normal vision.
Photo shows hyperopia.
Note the size and placement of the crecents in the pupil. Many of the families whose children show symptoms of amblyopia have no idea the children suffer from vision problems. Children often do not exhibit signs that parents recognize. The Amblyopia Screening program is an effective tool in both identifying amblyopia and emphasizing to parents the importance of regular eye exams from infancy and on.
