A cooperative, charitable research project to vision screen every preschool Alaskan

the Ideal Photoscreener

“The ideal photoscreener is portable, simple, and user-friendly for children and parents. It should be quick and inexpensive. It should focus on active children in reduced illumination. It should be capable of instantaneously demonstrating a good image, capable of obtaining orthogonal images and capable of storing and transmitting images for interpretation. The ideal photoscreener allows efficient and infallible identification of each child. The ideal photoscreener has high validity detecting refractive and strabismic amblyopia risk factors and whether the ocular media are blocked. The ideal photoscreener also provides rapid interpretation of the image so the parent can either a) be reassured of probable normality, or b) seek a confirmatory complete eye examination soon. Inconclusive interpretations due to inadequate photoscreen image quality or fixation are frustrating for parents.”
