It is now possible to achieve pediatric vision testing in a school setting or in medical fairs thanks to revolutionary vision testing device known as the vision screener. This is a device that works in amazing manner and is able to capture several details from the eyes, perform measurement and compare them to predetermined data and give back results in a fraction of a second. It is now common in health fairs, preschools and grade schools, medical institutions and may also be available in hands of pediatricians and family doctors as it is not restricted to opticians only.
With solid scientific background and support from several studies and testimonials published in medical journals, this is a device that has gain favor with several medical professionals, government agencies and non-governmental organizations alike. Currently, it is used by nurses in schools, pediatricians, opticians, members of the Lions club and many other professionals. The only required compliance is the camera fixation and there is a specially designed sound to achieve by provoking fixation.
The only required compliance is a short camera fixation. It has high level of accuracy and the results can be fully trusted. It is also able to screen two eyes all at once and the distance required for screening is about one meter or 3.3 feet from the camera. After just 0.8 seconds, the (PASS or REFER) results can be displayed on the screen automatically.
This simplicity in operation makes it possible for any ordinary person with no training to be able to perform the screening. When the person to be screened is in the correct position, the device trigger is pulled. This result to a unique sound that helps achieve fixation after which the images of eye balls are captured on a white triangle on the screen. Several measurements then follows after which the results can be displayed. The tolerance level is set at +-2 inches or +-5 centimeters.
The measurements performed revolve around refraction size, the size of the pupil and the cornea reflexes. These are then compared with the data used for referral to determine if they are within the normal range or not and the PASS or REFERAL results is then generated. In order to diagnose anisometropia, the refractions of both of the eyes are compared and the deference compared with the standards reference.
There are several conditions that are detected after the performance of a number of measurements and tests which revolve around measuring and comparing the sizes of cornea reflexes, the pupil size and the refraction size. These data is then compared to predetermined data used for referral.
All the measurements are automatically performed followed by a PASS which indicates that all the measurements for all the conditions are within the normal range. In case one or more measurements does not fall within the normal range, the REFER measurement will be displayed.
These results can be saved as the device has an internal database. These can be displayed later on and for many patients in a chronological order helping in data manipulation and other uses. It eliminates the need for visiting an optician when unnecessary yet ensures that you have opportunity to seek help at the earliest sign of eye condition problem.
