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.
This means that even non-medical staff can actually perform the screening. The person to perform screening starts by pulling the camera trigger to start; this is followed by a sound that is meant to attract attention. The image of both eyes is captured on a white triangle on the screen that then allows for performing the necessary measurements. The recommended screening distance is one meter (3.3 feet) from the camera. The tolerance level is +-5 centimeters or +-2 inches. The results are then displayed on the screen in a matter of seconds.
Once the patient or a person to be screened is at the right distance from the camera; the operator then pulls the trigger which is followed by a unique sound used to help the patient focus at the device. The images of both eyes are then captured on a white screen after which the measurements of various parts are done automatically.
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.
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.
