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.
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.
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.
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.
