Anwendung einer +3-Brille bei frühkindlichem Sehscreening mit dem PlusOptix A12R

Abstract

Purpose. The aim of this study was to examine the benefit of +3-glasses as a supplement to the measurement of ob- jective ametropia using the PlusOptix A12R vision screener in children. Material and Methods. Experience from practice and the evaluation of the measurement results with and without the use of the +3-glasses are presented. In addition, a way of interpreting the results in practice is presented. Results. The measurement with both methods was evaluated in 1534 out of 2760 cases. The measurements showed no significant difference (z = -0.250, p = 0.802, r = -0.005), how- ever, showed greater scatter results in the measurement with +3-glasses. If you select the more positive measurement, the mean is shifted by 0.26 dpt (SD = 0.68) towards hyperopia. In addition, a lower scatter result and a significant difference to the measurement without glasses are achieved. This is in pairs between 0 D and 4.75 D, with an average of 0.27 (SD = 0.46), with 261 cases (17 %) differences of 0.75 D or more. Conclusion. If only the measurement with +3-glasses is con- sidered, there is no benefit at first. However, the professional selection between the measured values provides a more re- liable statement about the refractive status, especially about the influence of accommodative compensation of hyperopia. The cost-effective production of the glasses, a high acceptan- ce by the children, the low time required and the additional safety of the results speak for the use of the +3-glasses in early childhood vision screenings.
