The training level of volunteers and service groups is not known. These children need to be referred to an eye care specialist regardless of screening outcome. Rescreening Prior to referral children who do not pass part of the initial screening or who are unable to respond to screening should be rescreened within two weeks. Referral and Follow Up Sample forms are provided in the guidelines to notify parents of screening results, to follow up on referrals, and to receive results from the eye doctor. Survey respondents report using a variety of methods to notify parents of the results of their child's visual screening.
Some respondents report using more than one method.
Knowing the outcome of the referral for a professional eye examination is critical to the success of a vision screening program. Five percent of the schools screen for distance vision only if a student has a vision concern, not at any specific grade level. Table 2 below shows the instruments used for distance vision screening by the respondents. Some respondents report using a combination of instruments. A variety of other screening charts are used by respondents.
