Abstract
PURPOSE: To evaluate the refraction in children measured with Plusoptix® without cycloplegia vs. Retinomax® apparatus with cycloplegia. PATIENTS AND METHODS: Measure of refraction with Plusoptix® in children>1year old referred for systematic vision screening, then measurement after cycloplegia with cyclopentolate by the Retinomax® device. RESULTS: Thirty-three children were included, i.e. 66eyes. Mean age was 40.7months (minimum 12; maximum 114). The Spearman correlation coefficient for the spherical equivalent was 0.52 (Plusoptix® vs. Retinomax® comparison; P<0.0001=moderate correlation). The Spearman correlation coefficient was 0.73 for astigmatism (Plusoptix® vs. Retinomax® comparison; P<0.0001=strong correlation). The Plusoptix® sensitivity for measurement of refraction was 57%, 43% and 43% respectively for spherical equivalent, sphere and astigmatism. DISCUSSION AND CONCLUSION: The correlation of astigmatism values is strong, whereas the correlation of sphere values is moderate. Plusoptix® seems to be unable to measure the exact refraction, because there is too large a dispersion of refraction measurements with Plusoptix®, compared to the exact refraction measured with the Retinomax®. Moreover, the sensitivity of Plusoptix® is low. Cycloplegic refraction remains indispensable in children.
