The Science Behind iScreen
For pediatric practices, using the iScreen device is simple. Staff members can quickly snap a picture of a patient and upload it to the cloud with one keystroke. Five minutes later, they receive a comprehensive report on iScreen’s secure customer portal, which includes information about whether the patient is at risk for potentially serious vision abnormalities and needs to visit an ophthalmologist or optometrist.
Behind the scenes, the iScreen Vision Screener 3000 works by using a sophisticated set of rapidly timed flashes at different angles. This enables the device to digitally capture “red reflex” images of the eye. If the patient has potential vision issues, the light pattern captured in the image will vary.
Once the picture is taken, software performs an initial analysis of the image. Other vision screening devices stop here. But with iScreen, the picture next goes to one of our certified ophthalmic professionals who each analyze tens of thousands of images each year. This off-site analysis of every patient screening is unique to iScreen, ensuring a high degree of quality control compared to devices that only depend on automated analysis. When you receive your iScreen report, you can be confident in the results, knowing they were determined by professionals with years of ophthalmological experience.
