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 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.
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.
The diagnosis for astigmatism on the other hands depends on determination for cornea irregularities. For hyperopia and myopia, the farsightedness and nearsightedness are performed respectively. The pupil sizes are compared for anisocoria while the symmetry of eye alignment is necessary for the cornea reflex.
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.
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.
