The most-widely used Photoscreener in the end of the 20th Century was developed by Dr. Howard Freedman from Redmond, Washington. ABCD has had excellent experience with 18 of these cameras which were marketed and supported by a company called Medical Technology and Innovations (MTI). This same camera will be available from Feakins Howson Partnership since it is no longer supported by Eye Care International (5/06). By October 2006, Please contact Photoscreener, Inc. Dr. Freedman developed a sturdy, portable, simple-to-use device with a superb dim-light focusing mechanism called the EyeCor. This photoscreener was desiged to work with Polaroid 337 high-speed B&W film (this film has been replaced by 667 film and older cameras must be retrofit). The PhotoScreener takes two, sequential, orthogonal magnified images. The flash is oriented above, and to the right of the child so hyperopic light crescents are located down (not hidden by the brow) and the the child's left side. The camera runs on rechargeable batteries but also by A/C cord. A package of film will screen ten children, unless repeat images are required (highly recommended by ABCD if image quality not good on first try). |

News (5-06) from Jeremy Feakins, the other man behind this great tool: Firstly, in 1992 I
acquired the rights to the technology for a vision screening device (EyeCor)
from the inventor, Howard Freedman. I then established Medical Technology
(MTI) and using Dr. Freedman’s technology developed a vision screening
device MTI named the PhotoScreener. The Food and Drug Administration (FDA)
of the US Government in 1995 granted MTI marketing clearance for the PhotoScreener. |
