Eye doctors practicing primary care can benefit from the additional routine referrals generated by VERA and specialist eye doctors can help more students identified by VERA to improve their visual abilities. A practitioner who has encouraged his local schools to use VERA reported that as of the first 90 VERA referrals to his practice (many more have followed), VERA was 90% accurate in identifying students who subsequently benefited from vision therapy. He went on to state that:

"The difference between these VERA referrals and typical school referrals is the inclusion of evidence of visual skills dysfunction. Parents had also received written materials from the school and had been referred to websites discussing vision and learning. This resulted in parents more often appreciating their child's potential vision problems and the connection to classroom performance.

During the past year an additional school district and a private elementary school near the practice have also begun to use VERA. The director of special services in the first district to use VERA reported recently that their district currently has the lowest rate of student classification for special education in the county. This is not only due to VERA and subsequent vision therapy, but she says that screening and remediation of learning related vision problems have been a significant factor."

Research
VERA research has revealed that except for visual acuity, most vision screening has limited correlation to reading grade level and/or curriculum-based assessments. By contrast, visual efficiency correlates well with academic standing and the results of functional vision examinations. As you know, this type of vision screening requires expertise, and is why school screening misses many vision issues which affect learning.

Additional research defined VERA's accuracy in identifying students with visual efficiency problems when compared to teams of vision and reading specialists assessing the same students. VERA's identification protocol is approximately 60% sensitive (the proportion of actual positives which are correctly identified) and 90% specific (the proportion of negatives which are correctly identified as such).

Using VERA in a professional office
VERA's routine screening can be used as a pre‐examination screening for visual acuity, hyperopia and the presence of binocular vision for patients of any age. The visual efficiency screening can be given if the patient passes the routine screening or once their vision correction is in place. The entire screening can be run by an assistant and areas of potential weakness can then be confirmed during your examination. During or after the vision therapy evaluation, VERA can be used as a demonstration of need to patients and/or parents.

Even if your practice does not provide vision therapy services, screening for visual efficiency can enable an appropriate and appreciated referral with a minimum of time and effort.

NOTE: Because VERA's design is as an institutional screening, the program may differ from usual in-office testing as follows: The visual acuity screening has test lines which correspond to 20/20, 20/25, 20/30, 20/40, 20/70, 20/200 and 20/400. Other lines have been omitted to render an institution's vision screening more efficient without changing the pass/fail accuracy. Nonetheless, the program gives an accurate indication of whether or not your patient's visual acuity requires correction.

The routine binocular vision screening includes tests for suppression, stereopsis and phoria which are not scored individually. Passing the binocular screening requires passing any 2 of the three tests, indicating whether additional binocular testing is advised.
