Photoscreener FAQs
Photoscreeners
A photoscreener is a device, like the iScreen Vision Screener 3000, which captures two “red reflex” images of a child’s eyes. A “normal” red reflex means light is passing through the eyes normally and focusing on the retina in a way that creates symmetrical images – oftentimes a reddish color – in both eyes. Red reflex images that are asymmetrical, have dark spots, display a white-colored crescent-shaped reflex, or don’t create a red reflex at all can all be indications of various eye abnormalities.
The iScreen Vision Screener 3000 captures digital images of red reflex and corneal light reflex images from the eyes. Other photoscreeners, such as MTI, use film to capture images of the eyes. MTI’s device was the most-widely used photoscreener. It was developed by Dr. Howard Freedman from Redmond, Washington. Dr. Freedman developed a photoscreening device called the EyeCor. The EyeCor photoscreener was designed to work with Polaroid 337 high-speed B&W film (this film has been replaced by 667 films and older cameras must be retrofit). A package of film screened ten children. In 2004, the technology was sold to Eye Care International. Feakins Howson Partnership (FHP) purchased the PhotoScreener technology from Eye Care International. Although there are still many MTI devices in use, the film is increasingly difficult to find and many previous users of MTI are transitioning to digital photoscreeners such as the iScreen Vision Screener 3000?
No. Although our devices are based on similar principles of using a camera to obtain a red reflex image, there is no relationship between iScreen and MTI.
iScreen Vision’s photoscreener is a digital photoscreener, while MTI has a film-based photoscreener. iScreen’s Vision’s images are analyzed at a centralized analysis center to ensure consistency and quality, while MTI images are analyzed by the users of the device
Yes. Fill out our contact us form, and we will have our sales team contact you to discuss our trade-in options.
