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.
This important device is supported by a list of impressive testimonials resulting from validated studies which are qualified by positive reviews from the general medical profession and the public. It is so easy to use hence preferred by pediatricians, Lions club and school nurses. Given that the only necessary compliance is a short fixation of camera, this form of screening works for all children. The device works by producing a specially designed sound targeted to provoke the fixation.
The common features of this device includes its proven accuracy of screening results, ability to screen both of the eyes simultaneously and the fact that screening is actually performed in a distance of up to 3.3 feet or one meter away from the device. The process lasts for only 0.8 seconds after which either pass or refer screening results are displayed automatically as the test result. This allows for very easy use and interpretation. The user also enjoys variety of documentation options that are available.
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.
In order to come up with results, the measurements performed include determination of refraction size, pupil size and the corneal reflexes. These are then compared to referral criteria that are age based. For anisometropia, refractions of both eyes are compared while corneal irregularity is determined for astigmatism.
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.
The comparison of refraction of the two eyes is done for anisometropia while astigmatism is diagnosed by determining the cornea irregularity. For myopia and hyperopia, the nearsightedness and farsightedness are determined respectively. Other conditions that can be detected include anisocoria through the comparison of the two pupil sizes corneal reflexes which requires that symmetric eye alignment is determined. All these are done automatically after which the result is displayed.
The results can be saved and printed in different formats thanks to an internal database. The database makes it possible to review the previous records in an organized or chronological order. In addition to this, the device is also cheaply available hence saves a lot of money and time that could be wasted in having to visit an optician.
