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.
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.
Among several other features, the vision screening device gives results with proven accuracy and screens both eye balls simultaneously. In addition to this, the screening is done at a distance of one meter away (3.3 feet) from the camera. It lasts for only 0.8 second and displays results automatically on the screen. This makes it very easy to use and interpret the results that can also be stored in a data base for later reference through the various documentation options 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.
