Pediatric vision testing is normally recommended with the intention of detecting disorders early enough. The common disorders include amblyopia, misaligned eyes (strabismus) and refractive errors that may call for eye glasses. The most commonly used approaches include community settings such as schools, health fairs, or in medical institutions. Vision screener is the most important medical device that has made this form of testing so cheaply and easily accessible.
The devices enjoys support from published testimonials and findings in medical journals majority of which are validated and have been commissioned by renown medical professionals. The public on the other hands have added their support in praising the level of efficiency and importance of these devices. There are used by school nurses, pediatricians, opticians and Lions club because they are very easy to use. In fact, one does not need any medical background to use one and interpret the results.
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.
For this reason, both the use and result interpretation is very easy and you can also take advantage of the documentation options that are available. The operational procedure for the device is very easy and takes less than one second for the display of results. It is for this reason that even non-medical staff finds it easy to conduct vision screening.
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.
In order to diagnose myopia, the nearsightedness is checked and farsightedness checked for hyperopia. The other checks that are done include comparison of pupil sizes for both eyes for anisocoria and determination of symmetric eye alignment for corneal reflexes. All these happen automatically in seconds hence the immediate results displayed on the screen.
A PASS displayed on the screen implies that all readings are within the recommended limit meaning that none of the conditions has been detected. In case of one or more of measurements or not within the limit, the result displayed is a REFER. Either a REFER or PASS is displayed on the screen as soon as the measurement is complete.
This can either be a PASS that indicates that all measurements are within the normal range and hence none of the conditions has been detected. In case any of the measurement is not within the normal range, a REFER is the result displayed and it requires visiting the optician.
